Where is the Anti-Static Grounding Strip Installed on a Car?

Automotive anti-static grounding strips are installed on certain vehicles such as tanker trucks or those transporting hazardous materials. When these vehicles are in motion, actions like acceleration, deceleration, and bumping can cause the gasoline inside the tank to slosh around. The constant friction between the gasoline and the tank walls generates static electricity. If too much static electricity accumulates, it can become dangerous. Therefore, tanker trucks require anti-static grounding strips to safely discharge this static electricity. Regular household vehicles do not need such devices. Static electricity is a common phenomenon in daily life. For example, during winter when skin tends to be drier, touching metal objects can release static electricity, giving a person the sensation of being shocked. When different objects come into contact, the concentration and work function of charge carriers on their surfaces vary, causing these carriers to migrate from one surface to another. If the two objects are then separated, one will carry a positive charge while the other will have a negative charge. Static electricity is essentially a reaction that occurs when solids, liquids, or gases undergo friction, spraying, or sudden decomposition.
I remember when I was driving, static electricity was quite annoying, especially when getting in and out of the car during winter—always getting a little shock. Anti-static grounding strips are usually installed on the metal brackets of the rear bumper or the rear chassis area because those spots are close to the ground and can effectively discharge static electricity when parked. On my own car, the strip is fixed next to the exhaust pipe, bolted tight to ensure good metal-to-metal contact. When choosing the location, avoid moving parts—don’t install it on the shock absorber to prevent wear while driving. The height of the installation is also crucial—too high and it’s ineffective, too low and it might scrape the ground. As an extra tip, grounding strips don’t just prevent shocks; they also protect onboard electronics like navigation or audio systems from static interference. During regular maintenance, check if the strip is rusted and clean it promptly to extend its lifespan by a few more years.
When I first bought a car, I was also confused about this thing. Later, I learned that anti-static grounding strips are usually installed at hard points on the rear part of the car, such as the bottom of the bumper or the chassis near the wheels. Why install it there? Because as soon as you park, it grounds and discharges the accumulated static electricity. Installation is quite simple—just buy a ready-made strip kit and find a flat metal surface to clamp or screw it into. Newbies don’t need to worry, just avoid choosing plastic or insulated spots. Static electricity may seem minor, but when it accumulates, it can damage equipment or give you a shock when opening the door. After I installed mine on the side of the rear bumper, the problem decreased significantly. Just make sure the position doesn’t interfere with driving and stays suspended without dragging on the ground.
