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 clear communication with other drivers and careful space checks. Start by checking your mirrors to see traffic behind and in the lanes beside you. Then briefly look over your shoulder to check the blind spots in the direction you want to move, because vehicles can hide in those spots even when your mirrors show nothing. Signal your intention early so others know what you’re about to do. When you find a safe gap, smoothly steer into the adjacent lane, maintaining your current speed and steady steering so your movement is predictable. Finish the maneuver by settling into the lane and continuing to monitor traffic.

This approach avoids common risks: changing lanes at intersections is typically unsafe due to cross-traffic; changing lanes without signaling leaves others unaware of your plans; and attempting to move across multiple lanes in one motion makes it very hard to see vehicles in blind spots and increases the chance of a collision.
