Traffic signsAustria
51. Road surface
A road surface warning indicates that the road ahead may be uneven, damaged or in poor condition and could affect the stability, steering or braking of a vehicle. The hazard may include bumps, depressions, potholes, broken pavement or other irregularities in the road surface.
Drivers should reduce speed where necessary, maintain a safe distance and avoid sudden steering or braking when passing over an irregular surface. The exact meaning and appearance of the warning sign vary between countries, so drivers must follow the local traffic signs and regulations.

Warning for a bad road surface.
What should you do when you see a road surface warning?
Reduce speed where necessary, increase your awareness of the road ahead and be prepared for changes in the vehicle's stability or direction.
🔗 gov.uk • Great Britain Highway Code, Rules 226–237; national guidance example
Does a road surface warning impose a specific speed limit?
Not normally. A warning sign alerts drivers to a hazard rather than establishing a numerical speed limit. A separate speed-limit sign may be used where a particular maximum speed is required.

52. Provisional licence
A provisional licence allows a learner driver to practise driving on public roads before obtaining a full driving licence. The conditions vary between countries and may determine whether the learner must be accompanied by an approved supervisor, which vehicles may be driven, where and when driving is permitted and how long the licence remains valid. A provisional licence is normally subject to stricter rules than a full licence and is intended specifically for learning and gaining practical driving experience.
Wikimedia.org • Usien • CC BY-SA
What is a provisional driving licence?
The meaning depends on the jurisdiction. In Great Britain and Flanders, a provisional licence can authorise learning under specified conditions. In the Australian Capital Territory, a provisional licence follows the learner stage and assessment. It is not a universal synonym for a learner licence.

🔗 gov.uk • GOV.UK, driving lessons and learning to drive; GB learner rules
Can you drive alone with a provisional licence?
Check the jurisdiction, licence stage and its conditions. In Flanders, some provisional licences require a registered supervisor, while another option permits independent practice after approved training. In Great Britain, car learners must follow the supervision rules. Other countries may use provisional for a later licensing stage.
🔗 vlaanderen.be • Flanders, obtaining a category B driving licence; learner provisional licences
🔗 gov.uk • GOV.UK, driving lessons and learning to drive; GB learner rules
How long is a provisional licence valid?
There is no universal validity period or renewal procedure. Check the issuing authority’s rules for the particular licence. For example, Flanders distinguishes 18-month and 36-month provisional learner licences; another jurisdiction may use provisional for a different stage altogether.

53. Runaway truck ramp
A runaway truck ramp, also called an emergency escape lane, is a specially constructed lane designed to stop a vehicle that has lost effective braking, particularly a heavy vehicle descending a steep hill. The ramp may use an uphill gradient, deep gravel or another energy-absorbing surface to slow and stop the vehicle.
A driver who has lost braking ability should enter the escape ramp as early and safely as possible rather than trying to continue down the hill. Escape ramps are emergency facilities and must not be used for ordinary stopping, parking or turning.
Wikimedia.org • CC0
Can you use a runaway truck ramp for normal stopping or parking?
No. An escape ramp is an emergency safety facility and should be kept clear for vehicles that have lost effective braking or control.
54. City limit
A city limit is a boundary or roadside indication showing that a driver is entering or leaving a named city, town, village, locality or municipality. It is commonly marked by a place-name or boundary sign.
The meaning of these signs varies between countries. A city-limit or locality sign may identify an administrative boundary, a named settlement or a traffic-related boundary. It does not necessarily mark the beginning or end of a legally defined built-up area, and passing the sign does not always change the applicable speed limit or other traffic rules.
Wikimedia.org • Mate Csepanyi • CC BY-SA
What is a city limit?
A city limit identifies the boundary of a named city, town or municipality. A roadside place-name or boundary sign may identify that boundary, a locality or a legally defined built-up area; its exact meaning depends on the sign system.
🔗 gov.uk • UK Department for Transport, Know Your Traffic Signs, boundary signs
City limit.
End of city limit.
Does a city-limit sign always mark a built-up area?
No. A city-limit or locality sign may simply identify a place or administrative boundary. A legally defined built-up area can use a different sign or definition.
🔗 gov.uk • UK Department for Transport, Know Your Traffic Signs, boundary signs
What is the difference between a city limit and a built-up area?
A city limit identifies the boundary of a named place or administrative area. A built-up area is a traffic-law concept that may affect rules such as default speed limits. The two boundaries can coincide, but they do not have to.
🔗 gov.uk • UK Department for Transport, Know Your Traffic Signs, boundary signs
55. Cyclist crossing
A cyclist crossing is a designated place where cyclists cross a road or carriageway. It may connect sections of a cycle path or provide a specific crossing point where cyclists move from one side of the road to the other.
Cyclist crossings are usually identified by road markings, traffic signs or traffic signals. Priority rules vary between countries, so cyclists and drivers must follow the signs, signals and local traffic rules that apply at the crossing.
Wikimedia.org • Linie29 • CC BY-SA
How fast may cyclists approach an uncontrolled cycle crossing in Austria?
At a cyclist crossing (Radfahrerüberfahrt) without traffic lights or a traffic officer, cyclists generally must approach at no more than 10 km/h, unless no motor vehicles are currently travelling nearby.
Can a cyclist suddenly ride in front of an approaching car at an Austrian cycle crossing?
No. Section 68(3a) prohibits entering an uncontrolled cyclist crossing immediately and unexpectedly in front of an approaching vehicle. Cyclists must observe the crossing-specific precautions.
56. Horn
A horn is a sound-producing device used to warn other road users of danger or to attract their attention when necessary for safety. Most motor vehicles are equipped with an electric horn operated from the steering wheel. Traffic laws generally restrict unnecessary or excessive horn use, especially in built-up or residential areas. The horn should therefore be used as a warning device rather than as a way to express frustration or greet other road users.
Wikimedia.org • C. Löser • CC BY
What is a car horn?
A car horn is a sound-producing warning device used to alert other road users when their attention is needed for safety.
🔗 gov.uk • Great Britain Highway Code, Rule 112; national guidance example
When should you use the horn?
The horn should generally be used when a sound warning is necessary to help prevent danger or an accident. The exact circumstances in which horn use is permitted depend on local traffic laws.
🔗 gov.uk • Great Britain Highway Code, Rule 112; national guidance example
Can you use the horn to show annoyance?
Generally, no. A horn is intended as a safety warning device, and unnecessary or excessive use may be prohibited by local traffic rules.

57. Licence plate
A licence plate, also called a registration plate or number plate, is a plate displaying a unique registration identifier assigned to a vehicle by the competent registration authority. It allows the vehicle to be identified for purposes such as registration, traffic enforcement, taxation, insurance and parking control.
The appearance, format, placement and number of plates required vary between countries and vehicle categories. Drivers must ensure that required licence plates are correctly fitted, clearly visible and legible and must follow the local rules when a plate is lost, stolen, damaged or replaced.
Wikimedia.org • JoachimKohlerBremen • CC BY-SA
What is a licence plate?
A licence plate is a plate displaying the registration identifier assigned to a vehicle. It allows authorities and other authorised systems to identify the vehicle's registration.
Is a licence plate the same as a registration plate?
Yes. Licence plate, registration plate and number plate are different terms commonly used for the plate displaying a vehicle's official registration number.
What should you do if a licence plate is lost or stolen?
Follow the local reporting and replacement procedure. For example, UK guidance says stolen plates should be reported to the police and DVLA, and replacement plates are needed before driving. Check the registration authority’s procedure for a lost plate; it may differ from the theft process.
58. Charging station
A charging station is a location equipped with one or more charging points where the battery of an electric or plug-in hybrid vehicle can be connected to an electricity supply and recharged. Charging stations may be located along public roads, in car parks, at service areas or on private property.
Charging spaces may be reserved for vehicles that are charging and can be subject to parking restrictions, time limits, payment requirements or other conditions. Drivers must follow the traffic signs, parking regulations and charging instructions applying at the location.
Wikimedia.org • GT1976 • CC BY-SA
What is a charging station?
A charging station is a location where electric vehicles can be connected to an electricity supply to recharge their batteries. A station may contain one or several individual charging points.
🔗 tfl.gov.uk • Transport for London, electric vehicles and charging points; London example
Who can use an electric-vehicle charging station?
Charging stations are intended for vehicles that can be externally charged, such as battery-electric vehicles and plug-in hybrid vehicles. The exact vehicle categories permitted may be indicated by local signs or operator conditions.
🔗 tfl.gov.uk • Transport for London, electric vehicles and charging points; London example
Can a charging station have a maximum parking time?
Yes. Traffic signs, parking regulations or charging conditions may establish a maximum duration to encourage drivers to move their vehicles and make the charger available to others.
🔗 tfl.gov.uk • Transport for London, electric vehicles and charging points; London example
59. Dangers
A general danger warning sign warns road users of a hazard ahead that is not represented by a more specific warning sign. The particular danger may be explained by a supplementary panel, text, symbol or other indication placed with the warning sign.
Drivers should increase their attention, observe the road ahead and adapt their speed to the nature of the hazard and surrounding conditions. The exact appearance of the sign and the way the danger is identified vary between countries, so road users must follow the local traffic signs and regulations.
Wikimedia.org • ŠJů • CC BY-SA
What does a general danger warning sign mean?
A general danger warning sign indicates that there is a hazard ahead that is not represented by a more specific warning sign in the local traffic-sign system.
Warning for a danger with no specific traffic sign.
What should you do when you see a general danger warning sign?
Increase your attention, observe the road and surroundings carefully and adapt your speed where necessary so that you can respond safely to the hazard.
Does the sign impose a specific speed limit?
Not normally. A warning sign alerts road users to danger rather than establishing a numerical speed limit. A separate speed-limit sign may be provided where a specific maximum speed is required.
60. Cyclist
A cyclist is a person who rides and controls a bicycle. Cyclists are road users and, in many countries, bicycles are legally treated as vehicles, meaning cyclists must follow many of the same traffic rules that apply to other drivers together with rules specifically intended for cycling.
Cyclists should use designated cycling facilities where required, obey traffic signs and signals and ride in a predictable and safe manner. The exact rules governing road position, priority, equipment and permitted cycling areas vary between countries.
Wikimedia.org • Benreis • CC BY-SA
Where should cyclists ride?
This depends on local rules. Cyclists may be required to use a cycle path or designated cycling facility, while in other situations they may ride on the carriageway.
61. Bus
A bus is a motor vehicle designed to transport multiple passengers, usually along roads as part of public transport, school transport, private transport or another passenger service. Buses generally have more passenger capacity than cars and may be designed to carry seated passengers, standing passengers or both.
Special rules may apply to buses concerning the driving licence, passenger capacity, speed limits, seat belts, bus lanes, stops and passenger boarding. The legal classification of buses and coaches and the rules applying to them vary between countries, so drivers and passengers must follow the local traffic regulations.
Wikimedia.org • Ralf_Roletschek • GFDL
What is a bus?
A bus is a motor vehicle designed to transport a relatively large number of passengers. It may be used for public transport, school transport, private services or other passenger transport.
🔗 gov.uk • Great Britain Highway Code, Rules 83–88; national guidance example
🔗 gov.uk • Great Britain Highway Code, Rules 221–223; national guidance example

62. Police
Police are public authorities responsible for enforcing laws, maintaining public safety and managing situations that may affect road traffic. In traffic, police officers may control vehicles, enforce traffic rules, investigate collisions, direct traffic and respond to emergencies.
Road users must follow lawful instructions given by police officers or other authorised traffic-control personnel. Police directions may temporarily override traffic lights, road signs or normal traffic arrangements, depending on local law.
Wikimedia.org • Chris Sampson • CC BY-SA
What is the role of police in road traffic?
Police help enforce traffic law, investigate collisions and respond to risks on the road. For example, Greater Manchester Police describe targeted road enforcement, a round-the-clock roads-policing response and specialist serious-collision investigation. Exact responsibilities and powers vary by jurisdiction.
🔗 gmp.police.uk • Greater Manchester Police, Roads Policing Strategy2024–2026
Must you obey a police officer directing traffic?
Yes. Lawful directions given by an authorised police officer must be followed. In many countries, those directions take precedence over traffic lights, road signs and normal priority rules.
What should you do if police signal you to stop?
Slow down, follow the officer's directions and stop at a safe location as instructed. Do not make sudden movements or continue driving unless directed to do so.
63. Ambulance
An ambulance is a vehicle equipped and used to provide emergency medical assistance or transport patients to or between healthcare facilities. Ambulances may carry medical equipment and trained personnel who can provide treatment during transport.
During an emergency response, an ambulance may use warning lights and a siren and may receive special priority or exemptions from certain traffic rules. Other road users must follow the local rules for emergency vehicles, make sufficient space and avoid obstructing their passage.

What is an ambulance?
An ambulance is a specially equipped vehicle used to provide emergency medical assistance and transport sick or injured people.
🔗 gov.uk • Great Britain Highway Code, Rule 219, emergency vehicles; national guidance example
What should you do when an ambulance approaches?
Make space safely for an ambulance on an emergency response, following the local rules and any lawful directions. Slow down or stop where necessary without sudden or dangerous movements. Do not assume that its emergency status allows you to pass a red light or disregard another traffic control.
🔗 gov.uk • Great Britain Highway Code, Rule 219, emergency vehicles; national guidance example
Can an ambulance exceed the speed limit?
Many countries permit emergency vehicles to depart from certain normal speed rules during an urgent mission, subject to safety requirements and national legislation.
🔗 gov.uk • Great Britain Highway Code, Rule 219, emergency vehicles; national guidance example
64. Police signals
Police signals are hand gestures, body positions, lights or other signals used by police officers or other authorised persons to control traffic. They may require road users to stop, proceed, change direction or follow another temporary traffic arrangement.
Road users should observe and obey police signals even when they differ from the normal traffic signs or signals. The exact gestures and their meanings vary between countries.
Wikimedia.org • Pressestelle BFK Urfahr-Umgebung • CC BY
What should you do if a police officer gives a signal you do not expect?
Slow down, pay close attention and follow the officer's instruction. Do not continue simply because a traffic light or road sign would normally allow you to proceed.
65. European emission standard
A European emission standard, commonly called a Euro standard, is a European vehicle classification based on limits for pollutants emitted by vehicles and their engines. Successive standards, such as Euro 4, Euro 5 and Euro 6, introduced progressively stricter requirements for pollutants such as nitrogen oxides, particulate matter, carbon monoxide and hydrocarbons.
A vehicle's Euro standard is determined as part of its type approval and depends on factors including the vehicle category, fuel type and applicable emissions legislation when it was approved. Euro standards may also be used by authorities to determine access to low-emission zones, but local access rules vary between countries and cities.
Wikimedia.org • Rfeba • CC0
What is a European emission standard?
A European emission standard, or Euro standard, classifies vehicles according to the emissions requirements they had to satisfy when approved for use in the European market.
🔗 consilium.europa.eu • Council of the EU, Euro 7 adoption explanation, 12 April 2024
What do Euro 4, Euro 5 and Euro 6 mean?
Euro 4, Euro 5 and Euro 6 identify successive stages of European vehicle-pollutant requirements. The applicable limits depend on the vehicle, engine and pollutant, so a higher number does not mean that every individual numerical limit changed. Later stages can also alter testing and durability requirements.
🔗 consilium.europa.eu • Council of the EU, Euro 7 adoption explanation, 12 April 2024
Can petrol and diesel vehicles with the same Euro number have different emission limits?
Yes. The applicable emission limits and testing requirements can differ according to the vehicle category, engine and fuel type even when vehicles belong to the same general Euro generation.
🔗 consilium.europa.eu • Council of the EU, Euro 7 adoption explanation, 12 April 2024
66. Pothole
A pothole is a hole or depression in the road surface caused by wear, weather, water, repeated traffic loads or deterioration of the pavement. Potholes can vary greatly in size and depth and may develop gradually or become worse after freezing, heavy rain or repeated vehicle traffic.
Potholes can affect steering, braking and vehicle stability and may damage tyres, wheels or suspension components. Drivers and riders should observe the road ahead, adapt their speed and avoid sudden or dangerous manoeuvres when encountering damaged road surfaces.
Wikimedia.org • State Farm • CC BY
What is a pothole?
A pothole is a hole or depression that develops in a road surface when the pavement becomes damaged or deteriorates.
What should you do when you see a pothole?
Reduce speed when necessary, maintain control of the vehicle and avoid abrupt steering or braking. Only move around the pothole when this can be done safely without endangering other road users.
🔗 gov.uk • Great Britain Highway Code, Rules 226–237; national guidance example
Are potholes dangerous for cyclists?
Yes. Bicycle wheels can be strongly affected by deep holes or sharp edges, particularly when the cyclist has little time or space to avoid the hazard.
🔗 gov.uk • Great Britain Highway Code, Rules 226–237; national guidance example
67. Private property
Private property is land, buildings or other property owned or controlled by a private person, company or organisation rather than by a public authority. Examples can include private homes, driveways, company grounds, private car parks and access roads.
Private property may be completely closed to the public or may allow access to customers, visitors or other authorised users. The traffic rules that apply depend not only on ownership but also on whether the area is open to public traffic and how it is legally classified.
Wikimedia.org • Herzi_Pinki • CC BY-SA
What is private property?
Private property is property belonging to a private person or group, rather than being available for everyone’s use. In a road context, check the actual access rules before entering private land.
🔗 dictionary.cambridge.org • Cambridge Dictionary, ordinary private-property definition
Do road traffic rules apply on every private driveway?
Not necessarily. The applicable rules depend on the legal status and accessibility of the area. A driveway used only by its owner is different from a privately owned road that is open to general traffic.

68. Path
A path is a relatively narrow route intended for pedestrians and, where permitted, other road users or small vehicles. Paths may run through urban areas, countryside, parks, forests or between other roads and can be surfaced or unsurfaced.
A path is not necessarily the same as a footpath or cycle path. The road users permitted to use it depend on its legal status, width, traffic signs and local regulations.
Wikimedia.org • Tangopaso • CC0
Is a path the same as a footpath?
Not necessarily. A footpath is specifically intended for pedestrians, while a path may also permit cyclists or other users according to local rules.
Can cyclists use a path?
This depends on the legal status, width and signs applying to the path. Some paths permit cyclists, while others are reserved for pedestrians or particular users.
Can motor vehicles use a path?
This depends on local law. Some paths prohibit motor vehicles entirely, while narrow vehicles may be permitted on other paths unless traffic signs restrict access.
Who has priority when a path joins a larger road?
The applicable local priority rules determine who must give way. Special rules often apply when a minor path joins an ordinary road.
69. Particulates
Particulates, or particulate matter (PM), are tiny solid particles or liquid droplets suspended in the air. In road traffic, particulate emissions can come from vehicle exhaust, brake wear, tyre wear and road-surface wear, as well as dust that is disturbed by passing traffic.
Particulate matter is commonly classified by particle size. PM10 refers to particles with a diameter of up to approximately 10 micrometres, while PM2.5 refers to finer particles of up to approximately 2.5 micrometres. Vehicle emission standards, particulate filters and air-quality measures are used to reduce exposure to these pollutants.

70. Air pollution
Air pollution is the presence of gases, particles or other substances in the air at concentrations that can harm human health, the environment or ecosystems. Road traffic contributes to air pollution through exhaust emissions and through non-exhaust sources such as brake wear, tyre wear and road dust.
Important traffic-related pollutants include nitrogen oxides, particulate matter, carbon monoxide and volatile organic compounds. Some pollutants are emitted directly by vehicles, while others can form in the atmosphere through chemical reactions. Vehicle-emission standards, cleaner technologies and traffic-management measures are used to reduce these emissions.
Wikimedia.org • Emmanuelkwizera • CC BY-SA
What is air pollution?
Air pollution is the presence of harmful gases, particles or other contaminants in the air. Road transport can contribute through engine emissions, vehicle wear and dust; the sources and pollutants differ by vehicle and conditions.

71. Rush hour
Rush hour is a period when roads and public transport networks experience particularly high demand, commonly because large numbers of people are travelling to or from work, school or other regular destinations. It usually occurs during the morning and late afternoon or evening on working days.
Rush-hour traffic can result in congestion, slower speeds, longer journeys and frequent stopping. Drivers should maintain a safe following distance, remain patient, anticipate changing traffic conditions and follow any temporary or dynamic traffic-management measures.
Wikimedia.org • MDRX • CC BY-SA
What is rush hour?
Rush hour is a period when unusually large numbers of people travel at the same time, resulting in increased traffic and often congestion.

72. Road code
A road code is a collection of laws and traffic rules that regulate how people use public roads. It establishes rules for drivers, cyclists, pedestrians and other road users and covers subjects such as priority, speed, overtaking, parking, traffic lights, road signs and road markings.
Road codes differ between countries and sometimes between regions. Every road user is expected to know and follow the rules that apply where they are travelling, even when those rules differ from those in their home country.
Are road codes the same in every country?
No. Although many traffic rules and signs are similar internationally, each country establishes its own traffic legislation and may apply different rules, signs, speed limits and requirements.
73. Street gutter
A street gutter is a narrow channel along the edge of a road or street that collects and carries rainwater toward drains or other drainage systems. It is commonly located between the carriageway and the kerb and may be formed from concrete, paving stones or part of the road surface.
A street gutter is primarily a drainage feature rather than a traffic lane. Road users should take care near gutters because they may contain water, debris, drain openings or uneven surfaces.
Wikimedia.org • Airman 1st Class Alystria Maurer • CC0
Why should cyclists take care near street gutters?
Gutters may contain water, leaves, debris, drain covers or uneven surfaces, which can reduce grip or make cycling less stable.
🔗 gov.uk • Great Britain Highway Code, Rules 226–237; national guidance example
74. Cargo bike
A cargo bike is a bicycle designed to transport goods, children or other larger loads than can normally be carried on a conventional bicycle. Cargo bikes may use a box or platform in front of or behind the rider, an extended rear carrier or a multi-wheel design.
Cargo bikes can be powered entirely by the rider or equipped with electric pedal assistance. Their permitted dimensions, passenger capacity, use of cycle paths and electrical-assistance limits depend on the local traffic and vehicle regulations.
