What is the best way to check your blind spots before changing lanes?

The best way to check your blind spots before changing lanes is to turn your head and look over your shoulder. This action allows you to gain a full visual perspective of areas not covered by your mirrors, which is crucial for safe lane changes. While mirrors are helpful, they may not capture everything, particularly smaller vehicles like bicycles and motorcycles that might be in your blind spots.

By physically turning your head, you are more likely to notice any vehicle that could be in your way, allowing for a safer maneuver. This technique is vital in defensive driving, ensuring that all potential hazards are considered before proceeding.
