You are driving a truck with a maximum authorized mass of less than 3,500 kg inside a tunnel where overtaking is prohibited. What safety distance must you keep from the vehicle in front?
Right of way
Explanation
When driving a truck with a **Maximum Authorized Mass (MAM) of less than 3,500 kg** through a tunnel where overtaking is prohibited, you must maintain a **safety distance of at least 100 meters** from the vehicle in front.
- This distance is necessary to avoid collisions in case of sudden and unexpected braking.
- In tunnels, it is crucial to maintain this minimum distance to ensure safety, as space is limited and conditions can be more dangerous due to lack of visibility and the possibility of gas accumulation.
- Vehicles that can carry more than 3,500 kg must maintain an even greater distance of **150 meters**, due to their larger size and weight, which requires more space to stop safely.
Therefore, for a truck of less than 3,500 kg, the correct distance to maintain is **at least 100 meters**.
