What does "checking your blind spots" mean?

Answer: B — Looking over your shoulder to ensure no vehicles are in areas you cannot see in your mirrors

Checking your blind spots means looking over your shoulder to ensure that there are no vehicles in areas you cannot see in your mirrors. This is a crucial safety practice for motorcycle riders, as blind spots are zones around your vehicle that cannot be viewed through your mirrors. By turning your head and visually checking these areas, you gain a complete understanding of your surroundings, which is essential when changing lanes or merging into traffic. This action helps ensure that you are aware of other vehicles that may be approaching from behind or to the sides, making it a vital part of safe riding habits.
