Which statement best reflects proper signaling before a lane change?

• A. Signal after you start the lane change.
• B. Do not signal if the road ahead is clear.
• C. Signal, check mirrors and blind spots, and ensure it is safe to move.
• D. Signal and move into the next lane immediately without checking.

Answer: (C)

Proper signaling before a lane change means you indicate your intention early, then verify the lane is safe before moving. Signal first to alert other drivers of your plan, giving them time to react. After signaling, check your mirrors and look over your shoulder or into your blind spots to see vehicles that may be in adjacent lanes or in areas not visible in the mirrors. Only proceed to move into the next lane if there is a clear gap and no one speeds up or blocks your path. The other options miss an essential step or safety check: signaling after you start the lane change reduces warning time; not signaling when the road seems clear denies others important information about your intentions; and signaling without checking and moving immediately bypasses the necessary safety verification before changing lanes.
