First let me say that I'm a retired long haul driver.Forty years worth. HK has it mostly right. Budd bars and "tire billys" are routinely carried by the drivers seat. But any cop CAN bust you for having a weapon within reach if he happens to be an asshole looking for one more ticket for the day. He knows it won't stick in court but he also knows the driver will usually just pay the fine by mail or bond if it's low enough simply because of time and hassle. Gotta pay for city or county services somehow. A truckers friend better be in the side compartment or tool box.That said I personally have never been hassled for it. But yes it can be considered a weapon. Mostly state troopers or a county deputy have more important things to do than that. Now if your in urban California or New Jersey that goes out the window. Many drivers also carry firearms hid or concealed but that is a federal felony if caught. Boils down to how much your safety is worth and more importantly how big of a mouth do you have. Just my experience.
