What actions are prohibited when driving on a motorway?

When driving on a motorway, certain actions are prohibited to maintain safety and ensure the smooth flow of traffic. Making U-turns is prohibited because it creates a dangerous situation on high-speed roads where vehicles are traveling at significant speeds. U-turns can lead to confusion for other drivers and increase the risk of collisions.

Stopping your vehicle on a motorway is also forbidden, except in emergencies. Stopping can disrupt the flow of traffic and pose a serious hazard to both the stopped vehicle and other road users. The speed of vehicles on motorways means that a stationary vehicle can be very hard to see and can lead to serious accidents.

Picking up passengers is not allowed because it can cause delays and lead to unsafe situations where drivers need to navigate complex movements while traffic is moving at high speeds.

Given these reasons, all the actions listed are prohibited on motorways to ensure the safety of all road users and maintain efficient traffic flow. Thus, the choice that encompasses all these restrictions captures the essence of motorway safety regulations.
