Do speed humps reduce cut-through traffic?

Their primary purpose is speed reduction. Traffic diversion is a side effect; some motorists may avoid humps by using nearby streets, which is a potential disadvantage.

What types of speed humps are available?

Common designs include circular speed humps (12 ft long) for neighborhood access streets and flat-topped speed humps (22 ft long) for local neighborhood streets.

What are the material and color options for the speed bumps?

They are moulded from durable recycled rubber. Available in black and yellow, with the yellow color being a rubber compound compressed into the bump, not painted on.

Product Q&A

Q:What is the difference between a speed hump and a speed bump?

A speed hump is a gradual rise (12-22 ft long, 3-4 inches high) allowing vehicles to pass at 20 mph without discomfort. A speed bump is abrupt (1-3 ft long), causing vehicles to slow to almost a stop.

Q:How do speed humps help control traffic speed?

They cause a gentle rocking motion that creates driver discomfort, encouraging drivers to slow down to 20 mph. They are placed every 200-600 feet on residential streets.

Q:What happens if I drive over speed humps at high speeds?

At high speeds, speed humps can cause significant discomfort and act like bumps, jolting the vehicle's suspension and its occupants or cargo.

Q:Can speed humps be installed on any street?

No, they are typically placed only on residential streets with no more than two lanes and a speed limit of 30 mph or less. They are not installed on curves, steep slopes, or near emergency facilities.

Q:How are drivers warned about upcoming speed humps?

Warning signs like 'Road Humps Ahead' are placed before the series. The humps are also marked with diagonal white stripes for proper visibility.
