Loose tow chains can cause instant wildfires
Planning on towing anything this year? Trailer, boat, dirt bike, jet ski, etc.? Here’s an important rule to keep in mind: always check for dragging chains.
If the chains attached to your rig hang down and scrape along the ground, those dragging chains can easily generate sparks, igniting roadside grass and plants and unintentionally starting a fire. And you might be miles away before it spreads!
Knowledge is key to preparedness
Many wildfires begin due to a simple lack of information. People don’t know what they don’t know about fire risks and how to avoid them. Properly securing tow chains is one area people may not be aware of, but letting them drag could have serious consequences.
Here are some tips for avoiding fires on the road:
- Before pulling away with your tow rig, check all chains to be sure they’re properly secured, well above street level.
- Make stops along the way to ensure no chains have come loose or fallen into a dangerous position.
- If you see another driver dragging chains or causing sparks, try to alert them to the danger.
- Can’t get the other driver’s attention? Consider making note of the vehicle and alerting a nearby police officer, sheriff’s deputy, or a non-emergency reporting number.
Another fire prevention tip for traveling on the road? Please don’t toss the remnants of anything you’re smoking out the window. Even a small smoking-related ember can cause major damage.

Dragging chains is a real concern
The risk of fires innocently started by someone with loose chains on a trailer is very real. California examples include incidents in Marin County and Mendocino County. But it’s not just a California problem. In fact, the great State of Montana has produced a helpful video on the subject.
Have a fun and safe summer—but please, if you’re towing, protect against sparks by checking for dragging chains.
