What is the maximum rail size allowed in Georgia?

I’m looking into getting a set of rails that extend from the front of your bumper so that I can ram other cars without causing damage to my truck. I want them to be as long as possible so I can get some real speed before nailing a slowpoke on my street. What’s the law with this?

Get a set of 'bull guards', cow catchers with receiver hitch for a winch-- then you have relatively legal emergency/safety accessory. Looks better on truck- if a car then the sort of police use 'push' bumper,light and siren external mounts that usually have a DOT approval sticker.

the law is, it's a crime to use your vehicle to run other cars off the road
