What should you be most concerned about when you see this sign?

This sign indicates that the shoulder is lower than the road in the area ahead. If you drift off of the roadway and one wheel drops onto a low shoulder, do not slam on the brakes or steer sharply to try to get back onto the roadway. This could easily cause you to lose control of your vehicle.

• Driving with your headlights out of alignment because one side of your car is higher than the other.
• Damaging a tire from drifting onto the shoulder.
• Hydroplaning, if the shoulder has water on it.
• Losing control of the vehicle if you drift onto the shoulder.
