Are your drivers and spotters speaking the same language?
Maneuvering a commercial truck and trailer into a tight spot or through a busy area in a yard is no easy feat. A common best practice is to use spotters to help drivers safely navigate through these obstacles.
Even with this additional set of eyes and ears, drivers must remain alert and effectively communicate with the spotter.
Common, basic hand signals
To help avoid hazards, a spotter directs the commercial driver using hand signals to make a desired vehicle movement. To be effective and safe, the spotter and driver must speak the same language.
Unlike some industries such as construction, the hand signals used throughout the trucking industry are not standardized. Drivers and yard employees should be trained on common, basic hand signals.
When at a shipper or receiver’s facility, the driver obviously has less control over the situation. The company’s standardized hand signals may not be recognized. The driver needs to discuss agreed upon hand signals with the yard or warehouse employee who is directing the driver.
The more commonly used hand signals that should be standardized include:
- Pull forward to the left
- Pull forward to the right
- Back up
- Back up — driver’s side
- Back up — passenger’s side
- Distance to travel
- Stop
- Slow down
- Emergency stop
Above all, the stop signal needs to be clearly understood. It could make the difference between a safe docking and a crushed worker. Variations include both arms crossed with hands in fists, or hands straight up. In any event, the driver and spotter must agree on the stop signal, reinforced by yelling loudly to stop.
Driver’s safety measures
A driver should assess their surroundings before backing up and following a spotter’s directions:
- Walk around the commercial vehicle, making sure nothing is in the path of the tires;
- Observe people in the area;
- Check for obstructions in the cab that would block the line of sight of the mirrors; and
- Verify the position of the spotter (i.e., back of the trailer using the passenger-side mirror).
The driver must stop the vehicle immediately when:
- Unsure of the spotter’s signals. They must clarify the meaning before proceeding.
- Their attention is drawn away from the spotter (including looking away from the mirrors). They should continue only after confirming the last signal.
Spotter’s role
Spotters have their own safety concerns. They must be alert to:
- The position of the trucks, and
- Other hazards approaching or in the truck or trailer’s path.
To ensure their own personal safety, they should:
- Wear bright clothing or a vest,
- Be visible in the driver’s passenger mirror,
- Avoid walking backward while giving instructions to the driver,
- Assume a position that’s a safe distance from the truck,
- Make sure nothing will be in their walking path, and
- Keep eye contact with the driver at all times.
To make sure the driver knows where the spotter is at all times, they may need to change positions frequently so that they are visible in the driver’s passenger mirror.
Key to remember: A driver and spotter must effectively communicate to ensure the safety of the truck, spotter, and bystanders in busy yards and loading docks.
