You’re safe in a car because the lightning will travel around the surface of the vehicle and then go to ground.
This occurs because the vehicle acts like a Faraday cage.
Michael Faraday, a British physicist, discovered that a metal cage would shield objects within the cage when a high potential discharge hit the cage.
What should you do if your car is struck by lightning?
If you are driving, pull to the side of the road, turn on your hazard lights, turn off the engine and wait out the storm. Fold your hands in your lap and avoid touching anything metal within the car.
Can you get electrocuted in a car?
When a car is struck by lightning, some of the current can flow through the vehicle’s electrical systems and metal things attached to the car such as radios, cell phone chargers, GPS units as well as car door handles, foot pedals, the steering column and the steering wheel.
What happens to your body when you get struck by lightning?
In the wake of a lightning strike
Immediately after being struck, the disruption the lightning would have caused to your heart’s electrical rhythm could result in cardiac arrest, one of the leading causes of death in lightning strike victims. The shock could also cause seizures or respiratory arrest.
