What is a proper procedure for changing lanes safely?

The procedure for changing lanes safely involves several critical steps, and looking over your shoulder while signaling is an essential part of that process. This method ensures that you are aware of your surroundings, particularly of any vehicles that may be in your blind spot, which are not visible in your mirrors. Signaling indicates to other drivers your intention to change lanes, promoting better communication on the road and reducing the likelihood of accidents.

Relying solely on mirrors does not account for the areas that are not visible in those mirrors, leaving potential hazards unrecognized. Focusing only on pedestrians disregards other vehicles and obstacles that could be present in the lane you are intending to enter. Following the correct procedure significantly enhances safety for everyone on the road.
