Thunderstorms bring unpredictable lightning strikes. While staying indoors is safest, a car’s metal chassis can protect you when you’re stranded on the road.
Contrary to popular belief, tires don’t provide safety. High‑energy bolts can melt rubber, as seen in bicycle and motorcycle incidents. Instead, the car’s body acts as a Faraday cage, directing the electric charge around the passenger compartment and safely into the ground.
Soft‑top convertibles pose a higher risk. Lightning can strike the fabric, ignite the roof, and start a fire. In such vehicles, seek shelter in a nearby building if a storm approaches.
When you spot early storm cues—darkening sky, sudden wind, distant thunder—pull to a safe spot. Turn off the engine, activate hazard lights, and keep windows closed. Avoid touching metal parts that are connected to the chassis: door handles, dashboard electronics, steering wheel, gearshift, and windows.
Lightning can travel through the ground and rainwater, so wait at least 30 minutes after the last audible thunder before re‑entering or touching the vehicle. Storms can strike miles away, so caution remains essential.
While passengers usually survive, the vehicle often suffers damage. Visual signs include burn marks, cracked or shattered glass, melted plastic, and scorch marks near the strike point. Airbags may deploy unexpectedly, and the front antenna or tires can melt.
Electrical systems are vulnerable: the vehicle’s ECU, sensors, and safety electronics can be fried, causing steering, braking, or engine failures. Even if the car runs, a post‑strike inspection by a qualified mechanic is advised.
