Explanation
Rumble strips are installed on roadways to alert drowsy or inattentive drivers that their vehicle is drifting out of the travel lane or off the road. These strips consist of raised or grooved patterns in the pavement. When a vehicle's tires pass over them, they create a loud rumbling sound and a noticeable vibration in the steering wheel. This sensory warning can help wake a driver who may be falling asleep, helping to prevent fatigue-related crashes.
