What should I do if my car breaks down on an expressway like NLEX or SLEX?

Turn on your hazard lights and steer the car onto the shoulder as far from moving traffic as you can. Set up your early warning device well behind the car, then have everyone get out and wait behind the guardrail, not beside the car. Call the expressway’s hotline, which is posted on road signs and on the toll ticket, for towing or roadside assistance.
