How should you use your mirrors before changing lanes?

• A. Check mirrors only after starting the lane change.
• B. Ignore mirrors and rely on instinct.
• C. Check rear and side mirrors to assess traffic; check blind spots before changing lanes.
• D. Change lanes suddenly without looking.

Answer: (C)

Before changing lanes, you should check your mirrors to understand what’s happening behind and beside you. Start with the rear-view and side mirrors to gauge traffic, gaps, and how fast others are moving. But mirrors don’t show everything—the blind spots are areas you can’t see in the glass. A quick shoulder check into the lane you want to enter makes sure the blind spot is clear. Once you’re sure it’s safe, signal and move smoothly into the lane. Relying on instinct or changing lanes without looking is unsafe and can put you and others at risk.
