Snow chains are a basic winter safety tool for commercial drivers, but they only help when they are installed correctly and used at the right time. This ETON training page gives drivers a simple reference before winter routes, mountain passes, or chain-control conditions.
Before you start
Park in a safe, level location away from traffic. Set the parking brake, turn on hazard lights when appropriate, and wear visible safety gear. Do not try to install chains in an unsafe lane, blind spot, or shoulder position unless there is no safer option.
Check the chains before installation
- Confirm the chain size matches the tire.
- Lay the chains flat and remove twists.
- Inspect cross chains, hooks, cams, and fasteners for damage.
- Keep the hooks facing away from the tire sidewall when the chain design requires it.
Basic installation steps
- Drape the chain evenly over the tire with the cross chains centered on the tread.
- Move the vehicle only as needed to reach the inside and outside fasteners safely.
- Connect the inside fastener first, then connect the outside fastener.
- Tighten the cams or tensioners according to the chain style.
- Drive a short distance, stop safely, and recheck chain tension.
What drivers should watch for
Loose chains can damage tires, mud flaps, brake lines, and bodywork. Chains that are too tight or installed unevenly can fail under load. After installation, listen for unusual slapping, stop if the vehicle feels wrong, and recheck the setup before continuing.
When to remove chains
Remove chains when road conditions no longer require them or when posted chain controls end. Driving too far on clear pavement increases wear on chains, tires, and the road surface.
For ETON drivers, safety and preparation are part of the job. Review route conditions before departure, keep winter equipment ready, and ask a supervisor when requirements or conditions are unclear.
