In Stanton the average number of people injured per automobile accident is consistently higher for accidents involving a taxicab than for those not involving a taxicab. Although all Stanton taxicabs are equipped with passenger seat belts, taxicab drivers reporter that passengers tend not to use them. It is likely, therefore, that if taxicab passengers were required to use seat belts, the number of people injured per accident would soon be no higher for taxicabs than for other automobiles.
