Can Cars Avoid Lightning Strikes?

Automobiles do not have lightning protection capabilities. The car's outer shell is a large metal enclosure that forms an equipotential body, so people inside the vehicle don't need to worry about being struck by lightning. However, the vehicle itself is a conductor that easily attracts lightning. If lightning strikes the car, walking near the vehicle may expose you to ground-transmitted currents. During thunderstorms, avoid using mobile phones. The signal magnetic field of a phone changes during a lightning strike, and the powerful discharge process creates a strong electromagnetic field around. Car owners should retract external antennas and temporarily turn off car audio systems during thunderstorms to prevent lightning-induced currents from entering the vehicle and causing electrical circuit failures. When a car is struck by lightning, the instantaneous high voltage may damage electronic components inside, rendering electronic devices inoperable. Do not rashly exit the vehicle to inspect its condition, as the outside is more dangerous than the interior. During thunderstorms, even if the car runs out of fuel, do not refuel. In stormy weather, the air contains numerous charged particles. Refueling during lightning may introduce stray currents into the fuel tank, potentially causing fires. Additionally, if flammable fuel vapors disperse into the surrounding air and are coincidentally struck by lightning, both the vehicle and fuel tank could explode.
Cars can indeed provide some protection against lightning to a certain extent. During thunderstorms, the metal body of the car acts like a safe cage, directing the lightning's current straight to the ground and protecting the people inside from harm. This is called the Faraday cage principle, which sounds fancy but is actually quite simple: the car body surrounds you, and the current travels along the exterior, not entering the interior. However, this isn't 100% safe; if the tires aren't properly grounded or if you open the door and step out, the risk increases. From my years of driving experience, during thunderstorms, it's always safer to park in an open area, keep the windows tightly closed, and avoid touching metal parts—much safer than standing outside. Remember to check the weather forecast in advance to avoid unnecessary risks.
Avoiding lightning in cars is a topic I've researched online and experienced firsthand. During thunderstorms, a car is indeed a safe place: the metal body can redirect the lightning current around the interior, protecting you. I once encountered a sudden thunderstorm on the highway—the car shook quite frighteningly, but both I and the car were unharmed, thanks to this principle. However, don’t rely on it too much; tires have rubber, which provides decent insulation, but if parked near trees or on high ground, the risk of lightning strikes doubles. During thunderstorms, it's best to park in low-lying areas, turn off electronic devices like phone chargers, and ensure safe driving is the priority.
The lightning protection feature in cars is indeed present. The metal body of the vehicle can effectively conduct lightning current away, preventing injuries to people inside, especially in open areas where it is noticeably safer. However, potential risks still exist, such as conductive door handles or aging tires, which may lead to accidents. I have witnessed incidents of lightning striking cars where the occupants remained unharmed, but the outside was highly dangerous. Therefore, during thunderstorms, it is best to stay inside the car without unnecessary movement, and simply closing the windows can significantly improve safety.
