A truck’s no-zones are the places around the truck where the driver is either unable, or finds it extremely difficult, to see other vehicles. Most commonly, these “no-zones” are to be found on either side of the cab, roughly 20 to 25 feet in front of the cab, or as much as 200 feet from the truck’s rear. Remember, if you cannot see the driver in the truck’s mirror, the truck driver cannot see you.
