Checking Brakes
1. Apply towing vehicle semitrailer handbrake control.
2. Have assistant watch semitrailer wheels as you move semitrailer forward. Semitrailer
wheels should not move. If they move, recheck tractor-to-trailer airhose connections.
OPERATION
Driving
When driving the truck tractor and semitrailer, the overall length of the unit must be kept in mind when
passing other vehicles and when turning. Because the unit is hinged in the middle, backing is also
affected.
Turning
When turning corners, allow for the fact that the semitrailer wheels turn inside the turning radius of the
truck tractor. Make a right turn at a road intersection and then cut sharply to the right. This will
keep the semitrailer off the curb.
