You are driving in a two-lane one-way street and try to overtake the vehicle driving in front of you. The main risk in deviating to the left is:
- The crossing of an unbroken separation line.
- An incoming vehicle driving in your opposite direction might appear on the lane to your left.
- Correct answer: Disturbing a vehicle driving in the left lane.
- Disturbing a vehicle driving behind you on your lane.
Why this is the answer
The correct answer in the official bank: Disturbing a vehicle driving in the left lane.
On a one-way road all traffic moves in the same direction, so no oncoming vehicle is expected. The main danger when moving left is cutting into the path of a vehicle already driving in the left lane or approaching in it from behind. Before changing lanes, check your mirrors and blind spot, signal, and move over only when the lane is clear.
