Late at night, when crimes are more likely to happen, cop cars and taxicabs are often the only vehicles on city streets. Thus, the Taxicab, Limousine and Paratransit Association (TLPA)’s Transportation On Patrol (TOP) program trains taxicab drivers, and other “for hire” drivers, in a neighborhood watch program on wheels to assist law enforcement. TOP volunteers watch for criminal behavior, emergency situations and suspicious activity. This is reported to their dispatchers who in turn report the information to the proper authorities. Alternately, they can call 911 or a nonemergency police number on cell phones.
