More About Rumble Strips

This road safety tool simply alerts drivers by creating a rumbling sound as they drive over it. A cost-effective solution to reduce the number of accidents caused by inattentive drivers.

These markings are often referred to as audio-tactile line markings or audible lines. They are also known as sleepy bumps, waker-uppers, and drunk bumps.  

Speed moderation and lane dividing are crucial parts of traffic management. They make just the right amount of noise and vibration, warning drivers to slow down and stay in their lane. They don't crack or shrink, remaining strong and long-lasting. They protect people from potential danger from road crashes.

Frequently Asked Questions

What are rumble strips called in Australia?

In Australia, rumble strips are also commonly known as audio-tactile line markings (ATLM) or audio-tactile road line markings. They are typically small raised protrusions positioned along the edges and centre lines of roads.

What was the purpose of rumble strips?

The primary purpose of rumble strips is to alert inattentive or drowsy drivers through the vibrations and noise produced when their vehicle tires pass over them, helping prevent potential accidents by prompting drivers to remain attentive and focused on the road.

What is the speed limit for rumble strips?

It is advised that sleepy bumps should only be installed on road sections where the speed limit is 80 km/h or higher as they serve as a safety measure to warn drivers, especially when approaching certain road conditions or hazards.

Are rumble strips noisy?

Sleepy bumps can produce noise when vehicles drive over them, which is an intentional safety feature, as the noise alerts drivers and helps prevent accidents by promoting vigilance and attention to the road.

Why are they called "rumble strips"?

When a vehicle travels over a rumble strip, the driver hears an audible signal (a rumbling noise) and experiences vibrations. These sensory warnings effectively alert drowsy, distracted, or impaired drivers, decreasing the potential for accidents.
