What action should you take if you are unsure if the lane change is safe?

When you are unsure if a lane change is safe, the best course of action is to check your mirrors and blind spots. This step is crucial because it allows you to gather the necessary information about your surroundings before making a maneuver. Checking mirrors provides a view of vehicles approaching from behind or alongside you, while looking into blind spots ensures you are aware of any vehicles that may be in a position where they could not be seen in your mirrors.

Being thorough in your checks helps prevent accidents and ensures you make informed decisions. If you do not take the time to assess your environment, you increase the risk of colliding with another vehicle or causing confusion on the road. Safety should always be the priority when driving, and thorough checking before changing lanes is a fundamental practice for all drivers.
