Difficulty: Moderately Challenging
Step1
Remain with the vehicle. Do not leave the car or truck if caught out during a white out. Most times the vehicle will be spotted long before a person would be in a white out.
Step2
Keep the vehicle running for only 10 minutes at a time to keep warm. If the vehicle is left running the gas can expire more quickly, the car can overheat or the fumes inside the vehicle can overwhelm the people inside.
Step3
Roll down the windows slightly. This make sure there is enough fresh air coming into the vehicle so the occupants will not be overcome by the cars exhaust fumes.
Step4
Be sure that exhaust on the vehicle is not blocked. A blocked exhaust pipe can cause carbon monoxide to fill the vehicle.
Step5
Stay alert for carbon monoxide poisoning when caught in a white out. If people in the car become drowsy, dizzy, nauseous, confused or visually impaired, exit the car and let the vehicle air out.
Step6
Make sure the vehicle is clearly marked. Tie the brightest colored clothing available to the door handle or antenna.
Step7
Utilize the dome light in the car at night. This makes the vehicle more visible to passersby. However, only use it when the car is running or this may cause the battery to die.
