For reasons of safety and proper regulation, only State Police can summon such aid. State Police patrol the Parkway around the clock. Do not flag down passing vehicles. However, alert passersby to your need for help by tying a white handkerchief to the left-hand door handle, raising your car hood or blinking your lights. Passing motorists are asked to report such signals at the next toll plaza to expedite aid.
Tokens are valid indefinitely.
