Which sequence is recommended when preparing to change lanes?

• A. Signal, check blind spots, then merge into the target lane.
• B. Check blind spots first, then signal, then merge.
• C. Signal, check mirrors and blind spots, then execute.
• D. Check mirrors only, then change lanes.

Answer: (C)

The best sequence emphasizes letting others know your intention first, then thoroughly surveying the area before moving. You start by signaling to indicate you plan to change lanes, giving drivers around you time to react. After signaling, you check the mirrors to see what’s directly behind and in adjacent lanes, which helps you gauge speed and distance of traffic you might pass. Then you perform a blind-spot check to confirm there isn’t a vehicle in the lane you’re about to enter that you can’t see in your mirrors. Only when the space is clear do you execute the lane change smoothly. The other sequences fall short because they either skip the mirror check, delay signaling, or rely only on mirrors without confirming the blind spots, which can miss close or fast-approaching vehicles.
