(A) Any wrecker service which possesses a valid City of Dillon business license located within three (3) miles from the city limits of Dillon is eligible to be place on the wrecker rotation list. If a wrecker fails to respond to calls for service within fifteen (15) minutes from the time it is notified on three (3) separate occasions within a twelve (12) month time period, the wrecker service will be automatically removed from the wrecker rotation list regardless if the wrecker is located within three (3) miles from the city and possesses a valid City of Dillon business license.
(B) A city business license is not required of a wrecker service at the request of the owner or driver of a wrecked or disabled vehicle when there is nothing to indicate that the service was anything other than an isolated, incidental or casual one. Repeated services by a wrecker shall be considered as engaging in business and shall be required to obtain a business license.
