A wheel chock is a safety device used to prevent a truck or other vehicle from moving accidentally. 

If you want to know what may cause a truck to move, simply ask someone who has been run over by a speeding car or truck. It was most likely not choked. 

A wheel chock may be found in a variety of settings, including residential, construction, utility, industrial, mining, and even aircraft. 

We'll only cover applications in residential, utility, and industrial settings.

Possibility of an Accident

There are a few incidents that might cause a vehicle to move unexpectedly, some due to human error and others due to the pull of gravity. 

The following are some of the reasons for a truck's accidental movement:

• A truck stopped on an elevation with no parking brake or one that is worn out or damaged
• If parked on an incline, an overloaded vehicle may not be able to handle the weight and may begin to roll if not choked.
• A significant change in the weight of the vehicle when an item is withdrawn or added might cause movement.
• when no parking brake is used, particularly when the vehicle is parked on an incline.

Make It a Standard Operating Procedure

The basic truth is that if you know how to put down the chock and it's a habit for you, you're not as vulnerable. 

Whether you have just signed up with an independent company, utility, or phone provider, or are beginning a business where a wheel chock is a great idea to follow on a regular basis, the best thing to do as an individual is to get in the habit and remind yourself to do it. 

Put the following steps on your dash and, if necessary, on your staff washroom mirror for constant reminders:

• Set the truck or vehicle to park.
• Apply the parking brake.
• Put wheel chocks on both sides of the tire if you're on a slope.

That's the basics of remembering to use a wheel chock, so if you're in the delivery or maintenance business and need to stop your truck occasionally, use the chocks!
