If you look in your mirror and then plan to change lanes, you no longer see a car approaching from the rear. You should:

• A. Wait to change lanes until you are sure the car is not in your blind spot
• B. Change lanes quickly before the car returns
• C. Turn on your hazard lights
• D. Accelerate to pass the car

Answer: (A)

Before changing lanes you must verify the lane is truly clear by checking your blind spots, not just what you see in the rearview mirror. A vehicle can be hiding in a blind spot even if the rearview mirror shows nothing behind you, so perform a quick shoulder check to confirm there isn’t a car in the lane you plan to enter. If you’re not certain the gap is safe, wait. Quick lane changes or trying to beat a car back into view can lead to a collision. Hazard lights aren’t an appropriate signal for lane changes, and accelerating to pass while another driver could reappear in a blind spot increases risk. Move over only when you’re sure the lane is clear.
