- ACheck mirrors, signal, check blind spot, then change lanes.
- BCheck mirrors, check blind spot, signal, then change lanes.
- CSignal, check mirrors, check blind spot, then change lanes.
- DCheck blind spot, signal, check mirrors.
Show answer & explanationAnswer & 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.
