In the tunnel shown in the image, if you do not intend to overtake, what safety distance must you keep from the vehicle in front?
Right of way
Explanation
Minimum distance in tunnels without overtaking
- In a tunnel, if you are not going to overtake, keep at least **100 meters** or an interval of **4 seconds** from the vehicle ahead.
- For vehicles with **MMA > 3,500 kg**: minimum **150 meters** or **6 seconds**.
Why? In tunnels, there is **lower visibility** and **less space to maneuver**. Maintaining these distances gives you **reaction time** in case of sudden stops or incidents and reduces the risk of chain collisions.
