The new rules come after two porters from a car dealership were caught recklessly driving two deputy cruisers. The porters blasted loud music over the radio system -- jamming county communications. They also used the car's public address system to tell people to get out of their way on the freeway.
Those two porters have since been fired.
In order to drive deputy cruisers, new porters will have to go through background checks and training sessions.
Cars in tow will also now be marked with a half dozen signs reading "in tow."
