Which motor vehicles may freely choose their lane inside built-up areas?

All motor vehicles with a permissible total mass of up to 3.5 tons are allowed to choose their lane freely in built-up areas according to German traffic regulations. This rule promotes the efficient flow of traffic, allowing lighter vehicles to maneuver as necessary, especially in urban settings where road space may be limited. By designating this flexibility for these specific vehicles, the traffic rules aim to balance safety and traffic efficiency while maintaining order on the roads. It is essential to be familiar with such rules to ensure compliance and enhance road safety for all users.
