13. Proper vehicle maintenance should be followed including:

• Securing trailer chains, no dragging parts ensuring they do not drag on the ground.

• Check tire pressure, driving on exposed wheel rims will throw sparks.

• Carry a fire extinguisher in your vehicle and be prepared to use it.

• Properly maintain brakes, brakes worn too thin may cause metal to metal contact which can cause a spark.

• Do not drive your vehicle onto dry grass or brush. Hot exhaust pipes and mufflers can start fires that you will not even see until it is too late.
