Explanation
Rumble strips serve as an effective countermeasure against driver error by reducing run-off-road collisions through audible noise and physical vibration. When a vehicle crosses them, the combination of sound and vibratory warning alerts drowsy or distracted drivers, helping refocus their attention on maintaining proper lane position. These safety features-including shoulder, edge, and centerline rumble strips-are proven to enhance driver reaction times, ultimately decreasing crash severity on various road types, from freeways and multi-lane highways to two-lane rural routes.
