Safety

Every move matters.

Yard trucks, trailers, and people on foot share the same pavement. Our goal is zero harm, and our spotters follow these rules on every shift.

Our commitment

Your safety. Our priority.

That line opens our Spotter Orientation. The goal behind it is zero harm: everyone on the team goes home safe at the end of every shift.

Orientation covers yard rules, equipment inspections, coupling and uncoupling, backing, and defensive driving. It also covers the site itself: the buildings, the docks, the parking, and who to call on each shift.

The rules are enforced. Failing to report an accident, skipping a seat belt, and reckless driving are disciplinary offenses.

On every shift

Six rules our spotters follow.

  • Full pre-trip inspection

    Before every shift, spotters check the truck’s tires, fluids, lights, mirrors, and seat belt and log it on a daily inspection form. Steer tires need at least 6/32 inch of tread, and drive tires 4/32.

  • Three points of contact

    Spotters keep two hands and a foot, or one hand and two feet, on the truck every time they climb in or out. They face the truck, never jump down, and never get on or off while it’s moving.

  • Speed and people on foot

    Yard trucks stay at 20 mph or less. If a spotter loses sight of a pedestrian or another vehicle, they stop and don’t move again until they’ve confirmed everyone is safe.

  • Get out and look

    When a spotter isn’t sure the path is clear or the trailer will fit, they get out of the truck and check. They back at 1 mph or less.

  • Focus in the cab

    Seat belts stay on whenever the truck moves, at any speed, and nobody rides outside the cab. Phones go through a headset with one ear uncovered, and spotters don’t text while operating.

  • Report it right away

    Spotters report every collision, injury, spill, and hazard to their supervisor or central dispatch as soon as it happens, along with any unsafe work they see.

Coupling

Every hookup follows the same nine steps.

If a trailer isn’t locked on, it may slide off the fifth wheel. That’s why every hookup includes a tug test before the trailer is lifted.

  1. Inspect the fifth wheel

    Make sure it’s greased, working, and in the right position.

  2. Plan the pull-out

    Make sure you have room to pull the trailer away from the dock.

  3. Line up the kingpin

    Position the fifth wheel so it lines up with the trailer’s kingpin.

  4. Back in slowly

    Back to the trailer, shift into neutral, and set the fifth wheel flush with the bottom of the trailer.

  5. Connect the air lines

    Hook up the air lines and supply air to the trailer.

  6. Lock on

    Set the trailer brakes and back under until the fifth wheel locks onto the kingpin.

  7. Tug test

    Once you hear the lock, pull forward gently to confirm the trailer is securely connected.

  8. Raise the trailer

    Lift the trailer until the landing gear is off the ground.

  9. Pull the chocks and go

    Remove the wheel chocks if they’re in place, then move the trailer.
