TUCSON, Ariz. -- They're meant to keep you safe on the road, but not all "bumps" are created equal. In fact, there are three configurations normally installed to help slow down vehicles.
These are facts you won't learn in driver's ed., but you will in Big Al's Traffic School.
First, there is the Speed Bump. This is the "most aggressive" of the three, with the shortest length and tallest height. Most of these are found in shopping centers, apartment complexes and other private property. According to the City of Tucson, it does not allow these to be installed on city-owned roads.
The Speed Hump is a medium length with a short height. A lot of times, these are found in neighborhoods. The City of Tucson says humps have been shown to be very effective in slowing down vehicles. Recent speed hump studies have shown a 40-60% reduction in vehicles exceeding the speed limit.
Speed Tables are also found in neighborhoods, plus near schools. These are the longest of the three installations but has the shortest height.
If you would like to request for a speed hump to be installed in your neighborhood, you can fill out a form on the City of Tucson's website.
