They're called rumble strips, and they're designed to wake up fatigued motorists and keep them from drifting off the road.

They are called rumble strips and they are designed to alert you if you fall asleep at the wheel. I think they were first put on the shoulders for the semi drivers because they are known to fall asleep alot.

They are called rumble strips, and their used for when people start driving off the road they are alerted. Usually people who fall asleep at the wheel or who arent paying attention.

They cut lines in the pavement there so that if you run off the road because you fell asleep, it wakes you up and you can get back in your lane before you have an accident.

Rumble strips go across the road. What you describe some call a "road ratchet". Its to wake you up.
