What is the best way to check for vehicles in your blind spot?

The best way to check for vehicles in your blind spot is to quickly turn your head and glance over your shoulder. This action provides the most reliable method for detecting vehicles that may be present in the areas not visible in your mirrors. Turning your head allows you to see everything in that zone, including other drivers, cyclists, and pedestrians that may be right next to or behind your vehicle.

Using mirrors alone may not reveal all vehicles since blind spots are specifically areas around the car that cannot be seen through standard mirrors. While camera systems can offer additional visibility and help reduce blind spots, they cannot completely replace the need for checking visually. Listening for sounds of approaching vehicles is not a safe or reliable method, as it primarily depends on external noise and might not be effective in busy traffic environments or with quiet vehicles. Thus, turning your head and checking over your shoulder represents the most effective and proactive approach to ensuring safe lane changes or merges.
