Question 5849
You are driving a passenger car inside a tunnel where passing is prohibited. What safe following distance must you keep from the vehicle traveling ahead?
- At least 100 meters.
- At least 50 meters.
- At least 150 meters.
Show answer and explanation
Correct answer: At least 100 meters.
In the image, the no-passing sign is inside the tunnel. Since you are not allowed to pass, you must always stay at least 100 meters or 4 seconds behind the vehicle ahead, which is the minimum for passenger cars. The 150-meter gap is required for vehicles with a maximum authorized mass over 3,500 kg.
