First, if possible, advise the officer at the scene of your request so that he may relay the information to dispatch, and they in turn can relay the information to the wrecker service. When the wrecker service arrives on the scene, speak to the wrecker driver to make sure he knows the address of where you want your vehicle to go and make sure he/she knows who will be paying them when they arrive at the destination you requested. If no one is at the location to pay the driver, they will take the vehicle back to their storage facility and you will be charged for the extra mileage and storage of the vehicle.
