Blind spots are danger areas that cannot be seen in your mirrors.Before making any sideways movements, such as changing lanes or passing another vehicle, quickly turn your head to check for other vehicles. Avoid driving in someone else's blind spot. This can be just as dangerous as not checking your own. Speed up or drop back,but don't stay in the other driver's blind spot. When sharing the road with large trucks, be particularly aware of their blind zones. As a rule, if you can’t see one of the trucks side mirrors, the truck driver can’t see you. In addition, when merging in front of large trucks, be sure to allow substantial distance between you and the truck. This is because large trucks require greater braking distance to maneuver and stop.
