Speed bumps can be an effective means of reducing speed and promoting safe driving. There are certain regulations that govern the use of speed bumps. Though the details differ from place to place, there are some generalities among them.


In most areas, a speed bump located in a public parking lot or on a public road requires a permit. On private property, such permits are not required.

Speed Limit

Speed bumps are usually restricted to areas where vehicles travel at speeds of less than 25 mph.

Placement and Grade

The steepest grade usually permitted for a speed bump is 8 per cent. Typically, it is required that continuous speed bumps be more than 300 feet apart.


Signs should be placed warning motorists of the bump they are approaching. Different localities require different minimum distances from the bumps.


If a speed bump on private property results in damage to a vehicle or injury, the owner of the property could be held responsible. This could have legal or financial consequences.
