76. Power steering
Power steering is a steering system that assists the driver in turning the vehicle's wheels, reducing the physical effort required at the steering wheel. The assistance may be provided hydraulically, electrically or by a combination of systems.
Power steering makes vehicles easier to manoeuvre, particularly at low speeds and while parking. The amount of assistance may vary with vehicle speed so that steering remains stable and responsive during faster driving.

What happens if power steering fails?
Steering may become considerably heavier or a warning may appear. The driver should maintain control, reduce speed safely and have the steering system checked as soon as possible.

77. Visual scanning
Visual scanning is the driving technique of continuously observing the road ahead, mirrors, side areas and surrounding traffic to identify hazards and changing traffic situations as early as possible. Effective scanning means moving attention regularly between different parts of the traffic environment rather than concentrating on a single point.
Drivers should look well ahead, check mirrors regularly and observe relevant side areas and blind spots, particularly before changing speed, direction or road position.
Wikimedia.org • B137 • CC BY-SA
Why is scanning important?
Scanning helps drivers identify hazards earlier and gives them more time to adjust speed, position or direction safely.
78. Mirror
A mirror is a device fitted to a vehicle that allows the driver to observe traffic behind and beside the vehicle without turning away from the road ahead for an extended period. Vehicles commonly use an interior rear-view mirror and one or more exterior side mirrors.
Mirrors help drivers monitor surrounding traffic before changing direction, changing lane, overtaking, merging or slowing down. Because mirrors cannot show every area around a vehicle, drivers should also check their blind spots by direct observation where necessary before manoeuvring.
Wikimedia.org • Petar Milošević • CC BY-SA
What is a vehicle mirror?
A vehicle mirror allows the driver to observe traffic and other road users behind or beside the vehicle.
What is the difference between an interior and exterior mirror?
An interior rear-view mirror normally provides a view through the rear window, while exterior side mirrors provide views along the sides and towards the rear of the vehicle.
Can a damaged mirror affect road safety?
Yes. A cracked, loose, missing or badly adjusted mirror can reduce the driver's view of surrounding traffic and should be repaired or replaced when necessary.
79. Fuel
Fuel is a source of energy used to power a vehicle's engine. Common vehicle fuels include petrol, diesel, LPG, CNG and alternative fuels. Electric vehicles use electricity rather than conventional liquid or gaseous fuel.
Drivers should always use a fuel that is compatible with their vehicle. Using the wrong fuel can damage the engine or fuel system, while economical driving and proper vehicle maintenance can reduce fuel consumption.
Wikimedia.org • Santeri Viinamäki • CC BY-SA
Which fuels are commonly used in road vehicles?
Common road-vehicle fuels include petrol, diesel, LPG, CNG and compatible alternative fuels. Battery-electric vehicles store electricity in a traction battery; other electric-drive designs, such as fuel-cell vehicles, obtain their propulsion energy differently.

80. Fuel gauge
A fuel gauge is an instrument on a vehicle's dashboard that indicates approximately how much fuel remains in the fuel tank. It usually displays a scale from empty to full and may also include a low-fuel warning light.
The reading is an estimate and can change slightly when the vehicle is on a slope, accelerating, braking or cornering. Drivers should refuel before the tank becomes completely empty.
Wikimedia.org • Santeri Viinamäki • CC BY-SA
What does a fuel gauge show?
A fuel gauge shows the approximate amount of fuel remaining in the vehicle's tank. Most gauges use a scale between empty and full.
Is a fuel gauge completely accurate?
Treat the fuel gauge as an estimate and follow the handbook’s low-fuel warnings. Do not assume that one indicated level guarantees an exact usable quantity or remaining distance; the display and warning behaviour depend on the vehicle.
81. Petrol
Petrol, also called gasoline, is a liquid fuel commonly used in spark-ignition engines. It is produced mainly from petroleum and may contain renewable components such as ethanol.
Different grades of petrol are identified by their octane rating and ethanol content. Drivers should always use a fuel that meets the specifications recommended by the vehicle manufacturer.
Wikimedia.org • WhisperToMe • CC0
What is the difference between E5 and E10 petrol?
E5 and E10 indicate the permitted ethanol content of petrol. E5 contains up to 5% ethanol by volume, while E10 contains up to 10%. Drivers should check whether their vehicle is compatible with the selected fuel.

🔗 gov.uk • GOV.UK, E10 petrol explained; GB fuel-compatibility example
82. Diesel
Diesel is a liquid fuel used in compression-ignition engines. Unlike petrol engines, diesel engines ignite the fuel through the heat produced by compressing air rather than by using spark plugs.
Diesel fuels can contain renewable components such as biodiesel. Drivers should always use a diesel grade that is approved by the vehicle manufacturer, as using an incompatible fuel can damage the engine or fuel system.
Wikimedia.org • Okq8 se • CC BY-SA
Can every diesel vehicle use every type of diesel?
No. Compatibility depends on the vehicle and engine. Drivers should follow the manufacturer's specifications before using fuels such as B10, higher biodiesel blends or synthetic diesel.

83. Diesel exhaust fluid
Diesel exhaust fluid (DEF) is a liquid used by many modern diesel vehicles with selective catalytic reduction (SCR) systems to reduce harmful nitrogen oxide (NOx) emissions. In Europe it is commonly known by the trade name AdBlue.
DEF is not diesel fuel and is stored in a separate tank. It is a solution containing high-purity urea and water that is injected into the exhaust system, where it helps convert nitrogen oxides into less harmful substances.
Wikimedia.org • Lenborje • CC BY-SA
What should you do when the DEF warning appears?
Refill the DEF tank with fluid that meets the specification required by the vehicle manufacturer. Do not ignore the warning, because some vehicles can restrict operation or prevent restarting if the DEF supply becomes empty.

84. Car insurance
Car insurance is financial protection for risks associated with owning or using a motor vehicle. Depending on the policy, it can cover liability for injury or damage caused to other people, as well as damage to, theft of or other losses involving the insured vehicle.
The minimum insurance required by law varies between countries. Drivers can often purchase additional cover beyond the compulsory minimum, such as collision, comprehensive, theft, fire or roadside-assistance protection.
Wikimedia.org • Charles Edward Miller • CC BY-SA
What does car insurance cover?
Coverage depends on the policy. Liability insurance generally covers injury or damage caused to other people, while optional forms of insurance may also cover damage to the insured vehicle, theft, fire or other risks.

85. First aid kit
A first aid kit is a collection of medical supplies intended for providing immediate basic care after an injury or accident. A vehicle first aid kit commonly contains items such as sterile dressings, bandages, adhesive plasters and other basic wound-care materials.
Some countries require certain vehicles to carry a first aid kit, while in others it is only recommended. The kit should be stored where it can be reached when needed, and its contents should be checked regularly so that required items remain complete and usable.
Wikimedia.org • Red Cross • CC0
Why should a first aid kit be carried in a vehicle?
A first aid kit provides basic materials that can be used to treat injuries or control bleeding while waiting for professional medical assistance.

86. Fire extinguisher
A fire extinguisher is a portable safety device used to control or extinguish a small fire. Vehicle fire extinguishers are designed for fires that may involve materials, fuel, electrical equipment or other components, depending on the extinguisher type.
Some countries require certain vehicles to carry a fire extinguisher, while in others it is only recommended. An extinguisher should be securely mounted, readily accessible, suitable for vehicle use and kept in working condition.
Wikimedia.org • Senado Federal • CC BY
What should you do if your vehicle catches fire?
Stop safely, get everyone out and move to a safe place away from the vehicle. Call the emergency services. Do not open a burning engine compartment or put yourself at risk trying to fight the fire.
🔗 gov.uk • UK Highway Code, vehicle maintenance, Vehicle fire safety; 🔗 wegcode.be • Belgian Vehicle Technical Regulations, Article 70, extinguisher mounting (Belgian example)
Where should a vehicle fire extinguisher be kept?
It should be securely mounted in an accessible location and protected from damage. Drivers should also check its condition, seal and expiry or service information according to the applicable requirements.
87. High-visibility clothing
High-visibility clothing is clothing designed to make a person easier for other road users to see. It commonly uses bright fluorescent material combined with retro-reflective strips that reflect light from vehicle headlights.
High-visibility clothing is especially useful when a driver or passenger must leave a vehicle after a breakdown or emergency. Requirements vary between countries, so drivers should check whether a reflective safety vest must be carried or worn.
Wikimedia.org • Kecko • CC BY
Is high-visibility clothing compulsory for drivers?
This depends on the country. Some countries require a reflective vest to be carried in the vehicle and worn in specified breakdown or emergency situations, while others only recommend it.
🔗 gov.uk • GOV.UK, driving abroad and destination equipment requirements
88. First aid
First aid is the immediate assistance given to a person who is injured or suddenly becomes ill before professional medical help is available. Its purpose is to preserve life, prevent the condition from becoming worse and support recovery.
At a road accident, first aid begins with making sure the scene is safe, assessing the casualty and contacting the emergency services when necessary. Assistance should be limited to actions the helper knows how to perform safely.
Wikimedia.org • Cory H Jones • CC BY-SA
Should an injured person always be moved?
No. An injured person should generally not be moved unnecessarily because movement can worsen certain injuries. Moving the casualty may be necessary when remaining in the location creates an immediate danger, such as fire or approaching traffic.

89. Concrete step barrier
A concrete step barrier is a concrete vehicle-restraint barrier with a stepped or sloping face profile. It is used along roads or in central reservations to contain and redirect vehicles that leave their intended path and to reduce the risk of entering opposing traffic or reaching dangerous roadside hazards.
Concrete step barriers may be cast in place or made from connected prefabricated sections. Their containment level, impact behaviour and permitted movement depend on the particular barrier system and installation.
Wikimedia.org • Pushcreativity • CC BY-SA
What is the purpose of a concrete step barrier?
A concrete step barrier is designed to contain or redirect a vehicle that leaves its intended path. It can be used to separate opposing traffic or protect road users from dangerous areas beside the roadway.

🔗 highways.fhwa.dot.gov • US FHWA, barriers, terminals and concrete/cable system design FAQ
90. Barriers
Barriers are physical devices used to block, restrict, guide or separate traffic. They can protect road users, close roads or lanes, control access, separate opposing traffic or shield people and work areas from moving vehicles.
Road barriers may be permanent or temporary and can include gates, boom barriers, concrete barriers, movable barriers and other restraint or closure systems. Drivers must respect barriers and must not pass them when they indicate that a road or area is closed.
Wikimedia.org • Wfm • CC BY-SA
May you drive past a closed traffic barrier?
No. A closed barrier normally indicates that access is prohibited or unsafe. Drivers should stop and follow any accompanying signs, signals or instructions rather than attempting to drive around it.

91. Vehicle lights
Vehicle lights are lighting and signalling devices fitted to a vehicle to help the driver see, make the vehicle visible and communicate intentions to other road users. They include dipped-beam and main-beam headlights, position lights, daytime running lights, rear lights, brake lights, direction indicators, reversing lights, fog lights and hazard warning lights.
Drivers should use the appropriate lights for the visibility, weather and traffic conditions. Lights must be kept clean and in working condition, and lights that can dazzle other road users should only be used when permitted.
Wikimedia.org • Christopher Ziemnowicz • CC BY-SA
When should main-beam headlights not be used?
Main beams should be changed to dipped beams whenever they could dazzle approaching or preceding road users. The precise requirements and distances vary between countries.
92. Street lights
Street lights are fixed lighting installations used to illuminate roads, intersections, crossings, footpaths and other public traffic areas during darkness. They improve visibility of the roadway, road users and potential hazards.
Street lighting does not replace a driver's responsibility to use the vehicle's required lights or to adapt speed to visibility. Lighting levels can vary considerably between roads, and some roads may be only partly illuminated or completely unlit.
Wikimedia.org • Exploringlife • CC BY-SA
Should you use main-beam headlights on a well-lit street?
Main beam should not be used when it could dazzle other road users, and many countries require dipped beam instead on sufficiently illuminated roads. Drivers should use the appropriate lighting for the road and traffic conditions.
93. Dipped beam
Dipped beam is the low-beam setting of a vehicle's headlights. It illuminates the road ahead while directing the light downward so that it is less likely to dazzle drivers and other road users.
Dipped-beam headlights are normally used at night, in poor visibility and whenever main beam could dazzle another road user. They provide less illumination than main beam but are suitable for normal driving when other traffic is nearby.
Wikimedia.org • Ehsnils • CC BY-SA
What is the difference between dipped beam and main beam?
Dipped beam directs light lower and is suitable when other traffic is present. Main beam projects light farther ahead but must be switched off when it could dazzle other road users.
94. High beam
High beam, also called main beam, is the headlight setting designed to illuminate the road a long distance ahead. It provides stronger and farther-reaching illumination than dipped beam but can dazzle other road users if used incorrectly.
High beam is mainly useful on dark roads where there is no nearby traffic that could be dazzled. Drivers must switch to dipped beam whenever required by traffic conditions or national rules.
Wikimedia.org • Ehsnils • CC BY-SA
Can high beam be used on a well-lit road?
Often not when the existing road lighting already provides sufficient visibility. National traffic rules may specifically require dipped beam instead in adequately illuminated areas.
95. Fog lights
Fog lights are vehicle lights designed for use in conditions where visibility is seriously reduced by fog, snow or other severe weather. Front fog lights illuminate the road ahead at a low level, while rear fog lights make the vehicle more visible to road users approaching from behind.
Fog lights should only be used in the conditions permitted by local traffic rules. Rear fog lights are particularly bright and can dazzle or distract following drivers when visibility is good.
Wikimedia.org • Ehsnils • CC BY-SA
Should fog lights be used in normal weather?
No. Fog lights should only be used when the applicable traffic rules and weather conditions justify them. Rear fog lights in particular can cause unnecessary glare when visibility is good.
96. Front fog lights
Front fog lights are low-mounted vehicle lights designed to improve illumination of the road immediately ahead when visibility is reduced by fog, snow or heavy rain. Their beam is generally wide and directed low towards the road surface.
Front fog lights should only be used in the weather conditions permitted by local traffic rules. They are supplementary lights and should not be used unnecessarily in normal visibility.
Wikimedia.org • Ehsnils • CC BY-SA
Should front fog lights be used in normal weather?
Use front fog lights only where local law permits them and follow the vehicle instructions. Poor visibility is a common permitted circumstance, but exceptions differ. Do not assume that the same restriction or visibility threshold applies in every country.
97. Rear fog lights
Rear fog lights are bright red lights at the rear of a vehicle that make it easier for following road users to see the vehicle when visibility is severely reduced. They are much brighter than normal rear position lights.
Because rear fog lights can dazzle or distract drivers behind, they should only be used in the weather conditions permitted by local traffic rules and should be switched off when visibility improves.
Wikimedia.org • Ehsnils • CC BY-SA
Should rear fog lights be switched off when visibility improves?
Yes. They should only remain on while the conditions that justify their use continue. Exact legal requirements vary between countries.
98. Side lights
Side lights, also called position lights, are low-intensity vehicle lights used to make a vehicle visible and indicate its presence and approximate width. Unlike dipped-beam or high-beam headlights, they are not designed to illuminate the road far enough for normal driving at night.
Side lights are commonly used together with other vehicle lighting and may also be used to make a stationary or parked vehicle visible in darkness. Their required use depends on national traffic rules.
Wikimedia.org • Chris828 • CC0
Can side lights be used when a vehicle is parked?
Yes. In some countries, position or parking lights must be used when a vehicle is parked on the road at night or in poor visibility. The exact requirements depend on local traffic rules.
99. Turn signals
Turn signals, also called direction indicators, are flashing lights used to communicate a driver's intention to turn or move laterally, such as when changing lanes. They normally flash on the side towards which the vehicle intends to move.
Turn signals should be activated early enough to give other road users useful warning and should be cancelled once the intended movement has been completed. Signalling does not itself give the driver priority or make an unsafe manoeuvre permissible.
Wikimedia.org • Ehsnils • CC BY-SA
Are indicators required for Uruguayan turns and lane changes?
Yes. Use the corresponding side’s flashing indicators.

100. Hazard lights
Hazard lights, also called hazard warning lights, make all of a vehicle's direction indicators flash simultaneously. They are used to warn other road users that the vehicle or traffic situation presents an unusual or immediate danger.
Hazard lights may be appropriate after a breakdown, collision or when warning following traffic of a sudden hazard. They should not normally be used as a substitute for proper parking, signalling or vehicle lighting.
Wikimedia.org • Ehsnils • CC BY-SA
Can hazard lights be used to warn drivers behind of sudden congestion?
In many countries they may be used briefly to warn following traffic of an immediate danger such as a sudden queue. The exact rules governing their use vary between countries.
