When changing lanes, you should:

Slow down when making the move
Look over your shoulder for visibility
Turn on your hazard lights
Speed up for a quicker move

The correct answer is: Look over your shoulder for visibility

When changing lanes, looking over your shoulder will provide a better view of your blindspots and allow you to better assess the surrounding traffic, reducing the chances of a collision. Slowing down and turning on hazard lights are not necessary, as long as the lane change is executed smoothly and safely. Speeding up can increase the risk of a collision and should be avoided.
