Question 5997
In a tunnel, what safe following distance must you leave from the vehicle traveling ahead?
- Only the distance sufficient to avoid colliding if it brakes suddenly.
- At least 100 meters when you do not intend to pass.
- 200 meters.
Show answer and explanation
Correct answer: At least 100 meters when you do not intend to pass.
In a tunnel, if you do not intend to pass, leaving enough distance to brake without a collision is not enough. You must stay at least 100 meters or 4 seconds behind the vehicle ahead, or 150 meters or 6 seconds if your vehicle's maximum authorized mass is over 3,500 kg. If you intend to pass where it is allowed, you must still keep enough distance to brake.
