Quick Answer
A person can survive for up to 3 days inside a stranded vehicle, depending on factors like temperature, humidity, and air quality, but it's essential to make a plan and try to escape within the first 24 hours to avoid dehydration and CO poisoning.
Staying Alive in a Stranded Vehicle
When you find yourself trapped inside a vehicle after an accident, your primary goal is to stay calm and plan a course of action. The average temperature inside a vehicle can rise to 120°F (49°C) within an hour, so it’s crucial to use the sun’s shade and any available ventilation to cool down. Open your windows slightly to allow for airflow, but avoid opening them too wide to prevent heat from entering.
Signaling for Help and Staying Hydrated
Use any available materials to create a visible signal for help, such as flashing a mirror or using flares. Make sure to stay hydrated by drinking the available water, which should last for at least 2 days. Ration the water to avoid dehydration, aiming for 1-2 cups per day. If you have a first-aid kit, use it to treat any minor injuries.
Avoiding Carbon Monoxide Poisoning
Carbon monoxide (CO) is a silent killer that can accumulate inside a vehicle from the engine. Be aware of the signs of CO poisoning, such as headaches, dizziness, and nausea. Never start the engine inside the vehicle with the windows closed, as this can lead to rapid CO buildup. If you need to charge your phone or other devices, use a battery pack or a hand-crank charger to avoid the risk of CO poisoning.
