Backing & Maneuvering · Driver Training VideoUsing a Spotter & Hand Signals

Backing crashes are some of the most preventable crashes in this industry, and almost all of them trace back to the same root cause: the driver couldn't see what was behind or beside the trailer, and backed anyway.

Before you ever put the truck in reverse, get out and look. Walk the path the trailer will actually take, not just where the tractor is aimed — check for curbs, dock plates, parked equipment, and anyone on foot. If you can get a spotter, use one.

Position matters

A spotter belongs at the rear corner the trailer is swinging toward, somewhere you can hold them in your mirror the whole time — never directly behind the trailer, where a slow roll could catch them. Use one spotter, not two.

Agree on the signals before you move, not during. A waving arm pulling toward the body means keep coming. A raised fist, or crossed arms held overhead, means stop. Both hands up, urgent and repeated, means stop right now — no second-guessing that one.

The one rule that overrides every signal: if you lose sight of your spotter in the mirror, stop the truck immediately. Don't ease forward hoping they reappear, and don't guess where they went. Stop, wait, and re-establish visual contact before you move another inch.

Your company standard: get out and look before every blind or tight backing move, whether or not a spotter is available. When a spotter is available, use exactly one, agree on the signals before the truck moves, and treat losing sight of them as an automatic stop.

None of this is about slowing the job down by much — a good walk-around and a clear set of signals cost you a minute, maybe two. What they buy back is the one thing you can't undo: somebody's clearance, a dock door, a fellow driver standing where you couldn't see them.
