CDL · Passing and lanes

At which points during a lane change should you look in your mirrors?

Correct answer: All of these are correct.

Answer options

  1. AOnce you have finished changing lanes
  2. BJust after you start moving into the new lane
  3. CBefore you signal and again after signaling
  4. DAll of these are correct Correct

Why

Mirror checks are needed at every stage: before the move, after turning on the signal, right as the vehicle begins to shift lanes, and when the lane change is complete. A vehicle can slide into a blind spot at any moment, so one glance is not enough.

Tip Treat your mirror checks as covering the entire lane change, from before you signal until you are settled in the new lane.
