When should you check your blind spot when riding?

Checking your blind spot is crucial for safe riding, especially before changing lanes or merging. This area is typically outside of the standard line of sight and is not visible through mirrors alone. By checking your blind spot, you ensure that there are no vehicles or obstacles present that could lead to a collision.

It’s essential to be vigilant in this way, as other road users, like cars or bicycles, may occupy these hidden areas. Making it a routine practice to check your blind spot prior to making any lane changes or merging movements enhances overall safety on the road. The other options do not capture the necessity and frequency of checking blind spots during the most critical moments of riding.
