Whenever a Highway Patrol officer investigates an accident where the owner or operator is contacted at the scene, the officer shall inquire of the owner and/or operator as to what tow car he or she desires and attempt to secure the same. If the owner and/or operator requests a tow car from a considerable distance and another tow car can be obtained much closer and in the officer's judgment, should be, because of the hazardous situation created by wrecked vehicles, then it will be the officer's responsibility to explain to the owner and/or operator the importance of eliminating the hazard created by the wrecked vehicles by requesting the nearest tow car. When the owner and/or operator requests a tow car from a considerable distance and the wrecked vehicle can be pushed off the travelled portion of the highway with the assistance of persons at the scene, this should be done instead of calling a local tow car just to remove the vehicle from the travelled portion of the highway, and in such instances the owner and/or operator shall be informed that it is his or her responsibility to guard the wrecked vehicle until the arrival of the requested tow car.
