This is to transmit the static energy from the lorry to the ground. If you wear a certain type of rubber shoe and you step out of a car, you will feel an electric shock running through your leg. When we have a chain or a conductor,the potential difference between the ground and the vehicle is zero

Thanks,
This sounds more like it.
Sometime I get out of my car and locking the door some mild electricity strikes me.
Not the best of feelings.

What would happen though if the static in the trucks was not arrested?

upus. Almost doesnt count.

This shock is terrible, especially if u had been cruising for long hours, pushing the window helps but it looks crude.
There must be a way of doing this, I will try to hang a nyororo chini ya gari yangu.
