The license button or badge shall be worn by the driver on his hat or coat in a manner as is plainly visible. The photograph shall be conspicuously displayed in the vehicle. The licensee shall comply with the terms of this chapter and all ordinances or laws governing the operation of taxicabs and motor vehicle which may now be in effect or which may hereafter become effective.
