Question 1196

On roads outside built-up areas with three lanes in the same direction, may a passenger car towing a trailer use the left lane?

  1. No, under no circumstances.
  2. Yes, when the combination's length does not exceed 7 meters.
  3. Yes, but only to pass other vehicles.
Show answer and explanation

Correct answer: Yes, when the combination's length does not exceed 7 meters.

If the vehicle combination does not exceed 7 meters in length, it may use the left lane when circumstances warrant it and without obstructing those behind. The restriction to the two right lanes applies to longer combinations.
