A driver is traveling on a multi-lane highway and needs to change lanes. Before initiating the lane change, the driver should perform which of the following checks in the correct sequence?

  1. ACheck mirrors, signal, check blind spot, then change lanes.
  2. BCheck mirrors, check blind spot, signal, then change lanes.
  3. CSignal, check mirrors, check blind spot, then change lanes.
  4. DCheck blind spot, signal, check mirrors.
Show answer & explanation

Correct answer: A. Check mirrors, signal, check blind spot, then change lanes.

The proper sequence for a lane change is to first check mirrors to identify general traffic, then signal your intention, then perform a final check of your blind spot for vehicles you couldn't see in the mirrors, and finally, if clear, change lanes.

Why the other options are wrong

  • B. Signaling after checking mirrors and blind spot reduces the time others have to react to your intention.
  • C. Signaling before checking mirrors means you might signal into an unsafe situation without prior awareness.
  • D. Checking the blind spot before signaling is out of sequence and less effective.

Lane Change Sequence

The correct sequence for a lane change is to check mirrors, signal your intention, check your blind spot, and then, if clear, proceed with the lane change.

  • Mirrors first for general awareness.
  • Signal communicates intent.
  • Blind spot check is final verification.

Memory trick: Mirrors, Signal, Blind Spot: My Safe Bet.
