Magic Glasses: Spotters and Distraction
- Apr 2
- 3 min read
At first glance, a spotter is just someone helping a truck reverse into a site. Put on the Magic Glasses, and you see something else. You see either a strong safety control or a weak link. The difference is focus, positioning, and communication.
Quick Scene-Setter
A mobile crane or Hiab is reversing into a tight site.
There are parked vehicles. Workers moving nearby. A building with low eaves on the left-hand side. Limited turning space.
A spotter stands behind the truck guiding it in.
From a distance, it looks routine.
What Most People See
The truck is moving slowly.
A spotter walking behind it.
Occasional hand signals.
The driver is checking the mirrors.
It appears controlled.
But look closer.
The driver must:
Watch both side mirrors.
Monitor the rear camera.
Check the front corners of the cab.
Watch overhead structures.
Manage steering and braking.
Interpret signals.
If the driver must constantly look for hand signals, something gives.
Usually, it is attention to a blind spot.
And the spotter?
Walking.
Looking over their shoulder.
Possibly distracted.
Possibly too close to the vehicle.
The risk is not speed.
The risk is divided attention and proximity.
What the Magic Glasses Show You
Reversing a crane or Hiab into a site is a high-risk activity.
You have:
Large blind spots.
Crush zones.
Swing areas.
Overhanging structures.
Pedestrians who may not understand the danger.
The hidden hazard is cognitive overload.
If the driver must:
Look for hand signals.
Watch mirrors.
Watch the front corner.
Check overhead clearance.
They are splitting their visual focus.
That increases the chance of:
Contact with a structure.
Striking a pedestrian.
Crushing a spotter who is standing too close.
Now compare the two approaches.
Approach One
Spotter relies on hand signals.
The driver repeatedly looks away from the mirrors to confirm signals.
Spotter stands close to remain visible.
Approach Two
Spotter uses a radio.
The driver instructs the spotter to stand clear.
Spotter positions outside crush zones.
The driver keeps eyes on the mirrors and the surroundings.
The driver uses their ears to receive instructions.
The second approach reduces exposure immediately.
Why Radios Improve Control
Using radios changes the risk profile:
The driver’s eyes stay where they should be - on mirrors, blind spots, and structures.
The driver’s ears receive information.
The spotter can stand further away and out of danger.
Clear verbal commands replace guesswork.
Communication becomes continuous, not intermittent.
The driver can also communicate:
“Stand clear.”
“Call stop early.”
“Watch the front left corner.”
“Check overhead clearance.”
“Stop.”
The spotter becomes an active risk controller, not just a signal giver.
Positioning Matters
A trained spotter should:
Stand where they can see the hazard.
Stand where the driver can hear them.
Stay outside crush zones.
Avoid walking backwards.
Avoid standing between the truck and fixed objects.
The driver should:
Confirm who the nominated spotter is.
Confirm the communication method.
Set a clear stop protocol.
Stop immediately if communication is lost.
No one else should give instructions.
The Real Risk
Magic Glasses do not just see a truck reversing.
They see:
A potential crush point at the rear.
A blind front corner.
A roofline or eave is at risk of contact.
A pedestrian entering from the side.
A distracted spotter glancing at a phone.
Distraction removes your primary safety control.
When the spotter is distracted, or the driver is overloaded, you have reduced margin for error.
The Controls That Matter
Nominate one spotter only.
Use radios where visibility is restricted.
Keep the spotter out of crush zones.
Set minimum stand-off distances.
Identify key blind spots before moving.
Identify overhead hazards before moving.
Establish a clear “stop” command.
Stop immediately if communication is unclear or lost.
No mobile phone use while spotting.
Magic Glasses Checklist – Spotters and Distraction
Is there one clearly nominated spotter?
Is the spotter positioned outside the crush zones?
Is radio communication being used where appropriate?
Has the driver identified the front corner and overhead risks?
Is the spotter free from distraction?
Is there a clear stop protocol?
Will the truck stop immediately if communication is lost?
Most reversing incidents do not start with speed. They start with distraction and divided attention.
A spotter is not just there to help the truck move. They are a safety control.
Free the driver’s eyes.
Keep the spotter clear.
Use clear communication.
That is what the Magic Glasses see.
Magic Glasses: The magic glasses come from the reality of - when I look at my books, I don't see a problem. But when my accountant looks at the books, it's a whole different story. He must have a special set of glasses.
As PCBU's, Officers and Workers, we have an obligation to learn what we are up to and the risks. Our actions and the standards we accept also affect those around us. This magic glasses post is made to help others see what we see.
