What should you do if you cannot see the truck driver's face in their mirrors?

If you cannot see the truck driver's face in their mirrors, the best course of action is to not change lanes. This is because large vehicles like trucks have significant blind spots, and if a driver cannot see you in their mirrors, they may not be aware of your presence. By refraining from changing lanes, you protect yourself and avoid potential collisions, as moving into a lane where the truck driver is unaware of your position could lead to dangerous situations.

Maintaining a safe distance from large vehicles and ensuring that you can be seen in their mirrors is essential for roadway safety. This is particularly important because truck drivers have limited visibility and are often unable to see smaller vehicles if they are in their blind spots. Thus, staying in your lane until you are confident that you can safely change lanes is a prudent decision that enhances safety for everyone on the road.
