Which action should be avoided during a lane change?

Speeding up to merge quickly during a lane change is a dangerous action to avoid because it can lead to loss of control and increases the risk of colliding with other vehicles. When a driver accelerates excessively while changing lanes, it can create unexpected situations for both the merging driver and other road users, compromising safety.

Maintaining a safe and consistent speed allows for better judgment by both the merging driver and nearby drivers. It's essential to signal your intention to change lanes so that other drivers are aware of your movements, and using mirrors and checking blind spots are vital in ensuring that the lane change can be conducted safely. Looking over your shoulder serves as an additional precaution to confirm that the lane is clear. Failing to adhere to these safety practices can result in serious accidents, highlighting why speeding up to merge quickly is inappropriate in lane change scenarios.
