A complete metal shield is necessary for full protection - so if you're stranded during a lightning storm, take cover inside a car with the windows wound up.
- Convertibles do not afford sufficient protection, even with the roof closed. A cloth top will not form a complete Faraday cage either and won't be safe.
- Fibreglass bodied cars are not safe as the outside body needs to be conductive to form a Faraday cage and fibreglass is an insulator.
- The person in the car must not be touching any metal object in the car
- Door and window handles, radio dials, CB microphones, steering wheels, and other inside-to-outside metal objects should be left alone during close-in lightning events.
- Small riding mowers and golf buggies are examples of unsafe vehicles.
