How can I avoid CO poisoning from my car or truck? Print

Exhaust from a car warming up outdoors.

  • Have a mechanic check the exhaust system of your car or truck every year. A small leak in the exhaust system can lead to a build up of CO inside the car.
  • Never run your car or truck inside a garage that is attached to a house even with the garage door open. Always open the door to a detached garage to let in fresh air when you run a car or truck inside.
  • If you drive a car or SUV with a tailgate, when you open the tailgate open the vents or windows to make sure air is moving through. If only the tailgate is open CO from the exhaust will be pulled into the car or SUV.
