根因分析

汽车的橡胶轮胎不能提供显著绝缘；金属底盘充当法拉第笼，将闪电导引至乘员周围。下车会使您暴露于直接雷击和地面电流。

English

A car's rubber tires do not provide significant insulation; the vehicle's metal chassis acts as a Faraday cage, conducting lightning around the occupants. Exiting the car exposes you to direct strike and ground current.

解决方案

  1. Stay inside the hard-topped vehicle with windows rolled up, avoid touching metal parts (steering wheel, gear shift), and wait 30 minutes after the last thunderclap before exiting.
  2. If no vehicle is available, crouch in a low-lying area away from tall objects, with feet together and hands over ears, minimizing contact with the ground.

无效尝试

常见但无效的做法:

  1. 75% 失败

    Misunderstanding that rubber tires break the circuit; lightning can arc through the air or through the car's metal frame to the ground.

  2. 60% 失败

    Assuming a convertible or soft-top car offers the same protection; it does not, as the Faraday cage requires a continuous metal roof.
