 And if you think you need to pull over to the side of the road, do so only if it's an emergency, and never pull over to the median side of the highway. Park as far from the highway as possible. Turn on your hazard lights, make sure all passengers get out of the vehicle, and light flares if you have them. And don't risk your life trying to change a flat tire on a dangerous highway. Carefully drive to the nearest exit. To learn more, visit nationalpolice.org.
