It is declared to be the purpose and intent of this chapter that all wreckers, towing
services and wrecker services doing business within the area of the metropolitan government
be licensed and required to have adequate insurance coverage in force as set out in
this chapter for the protection and welfare of the public. The provisions of this
chapter shall not apply to a wrecker service located outside the area of the metropolitan
government and which occasionally passes through or delivers vehicles within the area
of the metropolitan government, unless such wrecker service picks up or delivers such
vehicles within the area of the metropolitan government more than five times within
any thirty-day period. Or unless the license or permit of such wrecker service, wrecker
vehicle or wrecker driver has been revoked by the metropolitan transportation licensing
commission; or unless the wrecker service consists of any of the owners or partners,
or immediate family members of any owner or partner, of any company or firm, the license
of which has been revoked by the metropolitan transportation licensing commission.
