Rumble strips are a road safety feature that alert drivers by causing a tactile vibration and audible rumbling. They are most frequently encountered approaching an unexpected stop, such as a toll plaza. They may also be set horizontally across the road in groups, as a traffic calming method to slow drivers down.
Rumble strips were first implemented on the Garden State Parkway in New Jersey in 1952. Also known as "singing shoulders", they provided an alert system to prevent drivers from straying off the roadway.[1]
Rumble strips have also been placed within the double yellow line area in the center of the road, to alert drivers that drift into the opposing lane of traffic. And as recently as 2007, double-solid lines have been painted on newly paved sections of freeway for rumble strips to be more visible.
