Practice question

On a road, if there are double white lines and the line nearest to you is solid, what must you do?

  1. You must not cross the line.
  2. You may cross with caution.
  3. You may reverse to the next lane.
  4. You should overtake when safe.

Answer: A — You must not cross the line.

Double white lines divide traffic moving in opposite directions, and they indicate where overtaking is controlled. When the line closest to you is solid, you must not cross or straddle that line for overtaking. The restriction applies to your side, so you stay in your lane and wait behind the vehicle in front. You may only overtake if you reach a section where the line nearest you becomes broken and it’s safe to do so.
