Which statement best describes when you should change lanes?

• A. Change lanes whenever you feel space.
• B. Change lanes as soon as you see space, regardless of speed.
• C. Check mirrors only, then merge.
• D. Change lanes only when it is safe, signaling and checking, and execute smoothly.

Answer: (D)

Lane changes should only be made when it is safe. That means signaling your intention, checking for space in the lane you want to enter, and ensuring there is a clear gap before you move. You should also check again by looking over your shoulder to verify there’s no vehicle in your blind spot, and you may need to adjust your speed to fit smoothly into the traffic flow. Executing the maneuver smoothly helps other drivers anticipate you and avoids abrupt movements. If you change lanes just because you think there’s space, you might misjudge other drivers’ speeds or miss someone in your blind spot. If you rely only on mirrors without checking your blind spots, you could cut someone off. If you change lanes without signaling or without ensuring safety, you increase the risk of a collision. So the best practice is to signal, check, and move smoothly only when it’s truly safe.
