When should you check your mirrors?

Checking your mirrors before changing lanes, turning, or merging is essential for safe driving. This practice allows you to be aware of your surroundings and spot any vehicles, pedestrians, or obstacles that may be in your path. By doing so, you ensure that your maneuvers are safe and that you are not putting yourself or others in danger. This habit promotes defensive driving by keeping you informed about the traffic conditions around you, ultimately reducing the risk of collisions.

The other options suggest infrequent or poorly timed checks, which can lead to dangerous situations on the road. It's vital for drivers to maintain a regular habit of checking their mirrors, particularly before making significant changes to their driving path.
