What does checking over your shoulder help you identify?

Checking over your shoulder is a crucial driving technique that allows you to visually confirm the presence of any vehicle in your blind spot. These blind spots are areas around your vehicle that cannot be seen through standard mirrors. By turning your head and looking over your shoulder, you gain a wider field of vision that provides you with an accurate view of any vehicles or obstacles that may be hidden from your mirrors. This practice is essential for safe lane changes and merging, as it ensures that you are aware of your surroundings and can make informed decisions while driving. Recognizing vehicles in your blind spot helps prevent accidents and promotes safer road-sharing with other drivers.
