2. Motorway
A motorway is a road specially designed and signposted for motor traffic. Motorways normally have separate carriageways for opposing traffic, controlled access through designated entrances and exits, no direct access to neighbouring properties, and no level crossings with other roads, railways or paths.
Special traffic rules apply on motorways. The permitted road users, speed limits, lane rules, tolls and emergency procedures vary between countries, so drivers must follow the local traffic signs and regulations.

How can you recognise a motorway?
A motorway is normally identified by a special motorway sign at its entrance. It commonly has separate carriageways, controlled entrances and exits, and no ordinary intersections or direct access to neighbouring properties.
Who may use a motorway?
Motorways are primarily intended for motor vehicles capable of travelling safely at motorway speeds. Pedestrians, cyclists, animals and certain slow vehicles are generally prohibited, but the exact access requirements differ between countries.
What is the speed limit on a motorway?
There is no universal motorway speed limit. The applicable limit depends on the country, road section, vehicle category and driving conditions. Posted or variable speed-limit signs may replace the general national limit.
How should you enter a motorway?
Use the entrance or acceleration lane to observe motorway traffic and adjust your speed where possible. Enter only when there is a safe gap and follow the local priority and merging rules.
How should you leave a motorway?
Move into the correct lane in good time and signal when required. Enter the exit or deceleration lane before reducing your speed, unless traffic, signs or road conditions require you to slow down earlier.
Which lane should you use on a motorway?
Follow the local keep-left or keep-right rule and any lane-direction signs. Lanes closer to the centre of the motorway are commonly used for overtaking, but lane-use rules differ between countries and vehicle categories.
Can you stop on a motorway?
Voluntary stopping and parking are normally permitted only in designated parking or service areas. Drivers may still have to stop because of congestion, an emergency or another unavoidable situation.
Can you reverse or make a U-turn on a motorway?
Reversing, making a U-turn and driving against the direction of traffic are generally prohibited. If you miss an exit, continue to the next suitable exit.
What should you do if your vehicle breaks down?
Move the vehicle out of the traffic lanes when this can be done safely, activate the hazard warning lights and follow the local breakdown procedures. Leave the vehicle safely, keep away from moving traffic and use a warning triangle or safety vest where required by local law.
What is the difference between a motorway and an expressway?
A motorway normally has the highest level of access control and is governed by specific motorway rules. An expressway may have similar characteristics but may permit different road users or contain lower-standard junctions. The legal distinction varies between countries.
