Right Turn Around a Utility Pole with a 53-Foot Trailer

You are driving a 53-foot trailer with a 13-foot-6-inch height through a historic Georgia town. You need to make a right turn from a two-lane road onto a narrower two-lane street. A utility pole sits about 8 feet from the curb on the right corner, and a stop sign is on the left corner. The light is red, and a line of oncoming cars is waiting. Your trailer's rear axle is 40 feet behind the tractor's drive axles. The street you are turning onto has a parked delivery truck on the right about 60 feet past the corner. The tractor is a day cab with a 210-inch wheelbase, and your right mirror shows the trailer's right side but not the curb line. The pavement is dry, and you have a green light. A pedestrian is waiting on the right corner, and the street's travel lane is 10 feet wide.

1. Where do you position the tractor before starting the turn, and how do you use the mirrors through the turn?

Set up as far left in your lane as you safely can without crossing the centerline into the waiting oncoming traffic. The goal is to give the trailer's rear wheels room to track inside your path without climbing the curb or striking the utility pole. With the trailer axle 40 feet behind the drive axles, offtracking will be substantial; the trailer will cut the corner even if the tractor clears it.

Do not begin the turn when the tractor reaches the corner. Hold the wheel straight until the drive axles are nearly at the corner, then steer right smoothly. Watch the right mirror for the trailer tires and the pole; if the mirror does not show the curb line, lean or adjust the mirror before moving, or use a spotter. Watch the left mirror for tail swing, because the rear of a long trailer swings left as the tractor turns right. Keep the pedestrian in view and be ready to stop. A wide setup is useless if it puts you into oncoming traffic, so wait for a gap rather than forcing the turn.

2. What is the risk from the parked delivery truck 60 feet past the corner, and how does that change your plan?

Read the worked answer

The parked truck narrows the receiving lane to less than the full street width, and the trailer is already tracking to the inside of the turn. Because of offtracking, the trailer's right side will be closer to the right curb than the tractor's path, so the parked truck can become a collision hazard even if the tractor clears it easily.

Before turning, assess whether your trailer can complete the turn and still stay left of the parked truck. If the lane is too narrow, you may need to use more of the street, including part of the oncoming lane, but only after the oncoming cars have cleared and you have checked for pedestrians. If you cannot get the space, do not start the turn and then stop across the intersection; wait, or choose another route. A spotter at the right rear is useful. Keep the turn slow and watch the right mirror; the trailer's rear wheels are the ones that will hit the truck.

3. A car pulls into the gap on your right as you begin the turn. What do you do?

Read the worked answer

Stop the combination and hold it. The gap on your right is exactly where the trailer's rear wheels need to track, and a car there can be crushed against the curb or the parked truck if you continue. Do not swing left abruptly to avoid the car, because that can put the trailer into the oncoming lane or swing the rear of the trailer into the utility pole or the pedestrian.

Use the horn to warn the driver, keep your foot on the brake, and wait for the car to back out or for someone to direct traffic. If the car is blocking and cannot move, treat it as an intersection blockage: secure the brakes, put on hazards, and get help rather than forcing the turn. Once the gap is clear, resume the turn slowly and recheck both mirrors. The correct response is to protect the space the trailer needs, not to hurry through it.
