When making a right turn at an intersection in a tractor-trailer, you should:

When making a right turn in a tractor-trailer, position yourself in the rightmost lane, begin the turn slightly later (further into the intersection) than a car would, and keep the rear of the trailer close to the curb to prevent vehicles from squeezing into the gap on your right. Swinging wide to the left before turning right is one of the most dangerous habits a CDL driver can develop because it invites smaller vehicles to dart into the right-side gap and creates 'right hook' collisions. The correct technique uses the natural off-tracking of the trailer to bring it through the turn smoothly. If you absolutely must occupy two lanes to complete the turn safely on a tight street, signal early and use both lanes from the start so no driver tries to pass on either side.
