any vehicle as a taxicab unless the taxicab business or titleholder has obtained a
license issued by the unified government. Such license shall cover all vehicles used
as taxicabs operated by the taxicab business or titleholder. Such license shall be
required for the operation of any taxicab for which passengers are solicited within

for every taxicab providing transportation for hire between two points within the
city limits. At the option of the licensee, a vehicle for which a taxicab license
has been issued can be operated as a livery vehicle if, during such operation, a sign
is displayed on both the front and back of the right-hand sun visor stating in characters
at last two inches high: NOT IN TAXICAB SERVICE.
