In most cases and jurisdictions, towing companies are not required to notify the owners or drivers of illegally parked vehicles before towing them. This is as long as the parking facility’s parking policy is clearly communicated with the help of conspicuously posted and clearly stated signs and the two-away zones are properly identified. Most state laws do require the towing company to inform the appropriate authority/police about the towing action.  Certain state laws, such as that applicable in New Jersey, require police authorization before a vehicle can be towed away. California state law requires giving prior notice to vehicle owners in the form of either signage, parking violation notice issued at least 96 hours before towing, or notice to local law enforcement at least 24 hours before towing an obviously inoperable vehicle.
