Whenever the Clark Regional Communications Agency receives a request from the police department for tow truck service, it shall make a reasonable attempt to contact the tow truck service licensee first on the rotation list prepared for that purpose and shall instruct the first licensee contacted to respond. If the first licensee contacted indicates that it is unable or unwilling to respond at the scene with the appropriate equipment within twenty minutes of the agency’s call, the agency shall make a reasonable attempt to contact the next licensee on the rotation list. This procedure shall be followed for each subsequent licensee on the rotation list until a licensee can be contacted and indicates that it is able and willing to arrive at the scene within twenty minutes. Each licensee which the agency attempts to so contact shall have its name placed at the end of the rotation list regardless of whether it actually responded to the call, could not be contacted, or was unable or unwilling to respond as directed. (Ord. M-2507 §26, 1984)
