Before changing lanes, what should you do?

• A. Signal, check mirrors and blind spots, and ensure it's safe.
• B. Slow down significantly to create space.
• C. Change lanes without signaling if traffic is light.
• D. Accumulate speed to outrun others.

Answer: (A)

Before changing lanes, you need to communicate your intent and verify there’s a safe gap. Signaling lets other drivers know you’re moving over, while checking mirrors gives you an overall view of traffic behind and beside you. Because mirrors don’t show everything, a quick shoulder check to look into the blind spot is essential. If you confirm there’s enough space and it won’t force other drivers to brake or adjust suddenly, you can merge smoothly. This sequence helps prevent side-swipe collisions and keeps traffic moving safely. Slowing drastically, changing lanes without signaling, or trying to outrun others don’t provide a safe, predictable merge.
