Extremely Loud Sound Systems
Of course, the cops can’t give you a ticket if you have a massively powered audio system in your car and drive with it around. But if you pump that bass beyond the legal limits, be sure that a patrol car will follow you. However, the definition of “loud” varies from state to state. Also, most cops measure the decibel level as well as the distance from the car to determine if your audio system is too loud.
