Backing Into a Loading Dock at Night
It is 11 p.m. and you must back a 53-foot trailer into a loading dock on the right side of a narrow access road. The dock apron is dimly lit, there is a low concrete barrier on the left of the apron, and a parked forklift near the dock door. A yard worker is available but is standing near the dock door, not behind the trailer. There is no traffic on the access road. Your tractor has good mirrors and a backup alarm.

You should get out and look at the apron before backing - confirm the barrier position, the forklift location, and the clear path. Then position the tractor so the trailer is aimed straight at the dock before you begin backing, using a pull-up if needed to get the angle right. The yard worker should be repositioned as a spotter behind and to the side of the trailer, in your mirror view, not standing by the dock door where you cannot see them. Agree on hand signals before you start. Back slowly, using both mirrors, and stop if you lose sight of the spotter.
2. Why is backing to the right harder than backing to the left here, and what does that mean for your approach?
Read the worked answer
Backing to the right (the blind side for a left-hand-drive tractor) is harder because the trailer disappears from the right mirror sooner and the geometry is less visible. The practical answer is to avoid blind-side backing when possible: if the apron allows, approach so you can back from the left, or use a pull-up to convert the maneuver into a more visible one. If you must back right, use the spotter and go slower, checking both mirrors continuously. The judgement is to choose the approach that maximizes what you can see, not just the shortest path to the dock.
3. Halfway back, the spotter steps out of your mirror view. What do you do?

Stop immediately. A spotter out of view means you have lost your eyes behind the trailer, and the forklift and barrier are close. Do not continue on the assumption the spotter is clear. Set the brake, and either wait for the spotter to reappear in view or get out and look yourself. The rule is simple: if you cannot see the spotter, you do not move. Backing blind near a barrier and a forklift is exactly the situation that rule exists for.
