What is a safe lane change procedure?

• A. Change lanes only at intersections.
• B. Change lanes without signaling when traffic is light.
• C. Check mirrors and blind spots, signal, and move smoothly into the adjacent lane.
• D. Cut across multiple lanes in one move.

Answer: (C)

Safe lane changes rely on making a deliberate, visible, and controlled move into an adjacent lane. Start by checking your mirrors to see how fast and how close vehicles are behind you and in the lane you plan to enter. Do a quick over-the-shoulder glance to check the target lane’s blind spot. If the lane gap is clear, signal early so others know your intention. Then smoothly steer into the adjacent lane, keeping your speed steady or adjusting to fit the flow of traffic, and avoid abrupt moves that could surprise other drivers. Once you’re in the new lane, maintain a safe following distance and resume normal driving, then cancel the signal and do a quick check of your mirrors and blind spots.

This approach keeps the maneuver predictable and reduces the chance of a sideswipe or collision. It’s safer than changing lanes at intersections, which often leaves little room to complete the move safely. It also avoids changing lanes without signaling, which deprives other drivers of your intentions, and it rejects crossing multiple lanes in one hard, rapid move, which gives far less time to judge gaps and react to others.
