California Vehicle Code 22349 defines the maximum speed permissible on public highways.
The main purpose of a speed bump is to slow down traffic. A car going over a speed bump quickly risks damage to itself and its passengers. Speed bumps are best used in parking lots and other places where keeping traffic slow is important to avoid accidents with pedestrians and parked cars.
Speed bumps are designed to encourage a driver to drive slowly. Taking a speed bump at a high rate of speed will most certainly damage your vehicle.
If the public have access to the road, it is covered by the Road Traffic Act 1998 and is treated as a public road in the eyes of the law. Even so, it is unlikely that the police would be interested in assisting with enforcement, therefore the owner of the road may wish to install self-governing tools such as speed bumps and chicanes to slow traffic.
