Precautions and preparedness

If you are traveling this weekend or planning to recreate using ATVs or similar vehicles, take the following precautions to avoid starting a wildfire:

  • Avoid driving or parking your vehicle in tall grass.
  • Never throw a lighted cigarette out of a vehicle.
  • When pulling a trailer, attach safety chains securely; loose chains can drag on the pavement and cause sparks, igniting roadside fires.
  • Look behind you before driving away from fire-sensitive locations such as areas with tall grass or campsites to check for signs of a developing fire.
  • Always use a spark arrester on internal combustion engines.
