No vehicle shall be licensed as a taxicab until it has been thoroughly inspected by the Chief of Police or such other official as the Mayor and City Council may direct, and found to be in a safe, satisfactory and sanitary condition for the transportation of passengers. All such licensed taxicabs shall thereafter be inspected in the same manner quarterly between the first and fifth of January, April, July and October of each year. If any vehicle licensed as a taxicab is involved in a collision or accident, notice thereof shall be given to the Mayor and City Council or to such other official as they may direct, and an inspection shall be made of the taxicab before it can be again used in service. The report of all such examinations shall be filed with the Mayor and City Council. (1988 Code § 9-904)
