Speed Bump Regulations & Laws

- Where To Find Them

If you’re looking into installing speed bumps in your parking area or on a local side street, you’ll want to do your research first.  If you have a contractor doing the installation for you, they may already know what the requirements are.  But if not, you’ll need to find out to be sure you’re not doing anything that could cause problems later.

You may find that there are specific requirements that dictate the proper installation of speed bumps that are specific to your area.  The fact is that laws, regulations and recommendations vary everywhere you go.  These change from state to state, city to city and township to township.

For example, according to the state of California, speed bumps installed on public property such as a parking area or side street are supposed to be 3-1/2″ high x 12″ wide and must have a 6′ incline on either side of each location.  In contrast, in the state of Wisconsin, there are no regulations on file at all.  This means that the state allows each city or township to decide if there are specific requirements, and if so, what they might be. It is also up to the city or township to enforce these requirements.

If you have plans to install speed bumps, it is best to check city codes before you begin to be sure they’ll be installed within acceptable regulations.  You can start by visiting your local City Hall, Township or Code Enforcement office for instructions.  Normally they can give you written prints and instructions for installation to be sure they are installed in accordance with their guidelines.  There’s a good chance that if you install according to city requirements you’ll be within state codes as well.

A great online directory to help you get started in finding your state or local office would be www.StateLocalGovt.net.  Go there and simply select your state, for a listing of state offices that might be involved. If you want to find your local government website follow the links from your county.

Look for the “code and enforcement department” or even the “ordinance department” for some help.  They should be able to direct you to the rules and regulations that you’ll need to follow to install your speed bumps in your area.
