Can I ground myself while driving a car or truck?
You can’t ground yourself to the Earth while driving a vehicle. However, you can put an Auto Seat Mat on the car seat and connect the cord with an alligator clip to the metal chassis under the seat. The sweat from your body will create a channel of moisture and conductivity through your clothes to the mat.
The chassis represents a relative ground plane, enough to act as a “sink” into which you discharge the static electricity that builds up on the body as a result of the clothes you wear rubbing against the seat. This rubbing action, brought about by the vibration of the moving car, creates the static electricity on your body.
