Many motorists believe that truck or bus drivers can see the road
better because they sit higher than the driver of a car. In fact,
large vehicle drivers have serious blind spots into which a car can
disappear from view.
Side blind spot: Be careful when passing a large vehicle.
If you can't see the driver's face in his or her side mirror or
window, he or she can't see you and may not know you're there.
Front blind spot: When passing a large vehicle, make sure
that you can see the entire front of the truck or bus in your inside
rear-view mirror before you pull back in front. It takes a large
vehicle twice the time and room to stop as it does a car.
