Question 5466

You are driving your passenger car on this road outside a built-up area with one lane for each direction; if you do not intend to pass the truck, what safe following distance must you leave?

  1. The distance that allows the vehicle traveling behind to pass me safely.
  2. 150 meters.
  3. 50 meters.
Show answer and explanation

Correct answer: The distance that allows the vehicle traveling behind to pass me safely.

In the image, you are following a truck on a road with one lane in each direction and a broken line, and a car is visible in the rearview mirror. If you do not intend to pass, you must leave enough distance to brake, plus a gap that lets the driver behind pass you safely. If someone approaches from the opposite direction during the maneuver, that driver can move in between you and the truck. For a passenger car, the rule sets no fixed distance in meters; the 50-meter gap applies to vehicles with a maximum authorized mass over 3,500 kg or a length over 10 meters.
