The M7 Reversible Lane Boundary marking signifies a lane where traffic direction can change based on time or signals. This dynamic system is used to manage traffic flow, especially during peak hours. Drivers must always obey overhead lane control signals and signs, as the lane's direction can alternate. Incorrectly entering a reversible lane against the permitted direction is extremely dangerous and will be penalised.
Learn the key details of the M7 - Reversible Lane Boundary road sign, including its function, what it communicates to drivers, and how it applies in real traffic situations in Sweden. Use this overview to understand the sign clearly and recognise it confidently during the Swedish driving theory exam.
This marking defines lanes that can be opened for traffic in one direction at certain times and in the opposite direction at others. It is used where capacity needs change, such as rush hour corridors. The line helps keep the reversible lane separated from adjacent lanes while the direction is controlled by signals or signs. Because direction can change, drivers must pay close attention to lane control signals and not rely only on habitual patterns.

The M7 marking indicates a lane that can be used for traffic in one direction at certain times and in the opposite direction at other times. It's crucial to follow the dynamic lane control signals and signs, as the direction of travel can change.
You must pay close attention to overhead lane control signals (like lights) and any accompanying signs. These signals will indicate if the lane is open for your direction of travel and at what speed. Never assume the direction is the same as on a previous journey.
Entering a reversible lane against the currently permitted direction is extremely dangerous. It can lead to head-on collisions with oncoming traffic. Always prioritise the overhead signals and signs over any habitual patterns of driving.
A common trap is assuming the lane direction based on past experience. Always remember that the M7 marking requires you to constantly check signals. Another trap could be confusion with other lane boundary markings; focus on the associated signals for direction.
You can change lanes into or out of a reversible lane, but only when the overhead signals permit it and when it is safe to do so. Always check your mirrors and signal your intentions. Crucially, ensure you are entering or exiting the lane in the currently permitted direction.
The speed limit for a reversible lane is determined by the overhead lane control signals. These signals might display a specific speed limit or a general instruction. Always adhere to the posted speeds or signals for that lane.
