Okla. Stat. tit. 11, § 11-22-118

The municipal governing body is vested with full police powers,

for the purpose of preserving public health, safety and welfare,

over the operation, regulation and control of taxicabs within the

limits of the municipality. The municipal governing body may

prescribe regulations for the operation of taxicabs, which

regulations may include, and shall be limited to the following

specific powers and subjects:

1. Requirement of minimum insurance, bond or other indemnity

for public liability upon each taxicab; and if other than standard

insurance be permitted, requirement and specifications of terms and

conditions under which such other indemnity shall be accumulated,

held, maintained, managed, and disposed of to secure persons in

whose favor any liability shall arise out of the operation of

taxicabs;

2. Requirement of minimum standards of mechanical condition and

efficiency of any vehicle used as a taxicab, together with the power

to require inspections to insure compliance therewith;

3. Restriction of the loading of taxicabs to specified zones or

localities; including the power to prohibit and punish "cruising"

and the making of such other rules governing the manner of operation

of taxicabs as the public safety may require;

4. Determination, establishing, and enforcement of maximum

and/or minimum rates and charges to be made by taxicabs for the

transportation of passengers; including, but not requiring, the

establishment of zones as the basis of such rates, or the

requirement of taximeters as the basis of calculating such charges;

5. Requirement of municipal license for the operation of each

taxicab; together with the right to levy and exact an annual fee

therefor, and the right to revoke, cancel and thereafter refuse to

reissue such license for failure to comply with or for infractions

of regulations promulgated pursuant to this section. The granting

of any license may be made dependent upon the holding of a

certificate of convenience and necessity issued by the municipality,

if such certificates are provided as authorized by paragraph 6 of

this section; and

6. Requirement for the holding of a certificate of convenience

and necessity as a condition precedent to the issuance and holding

of a municipal license for the operation of a taxicab; including the

power to issue, deny, suspend and revoke such certificates.
