The use of speed bumps is widespread around the world, and they are most commonly found where vehicle speeds are statutorily mandated to be low,
usually 40 km/h (25 mph), or 8 to 16 km/h (5 to 10 mph) in car parks.
Although speed bumps are very effective in keeping vehicle speed down, their use is sometimes controversial as they can cause noise and possibly vehicle
damage if taken at too great a speed.
Speed bumps are very effective in front of schools, hospitals, dangerous places on streets to warn drivers and decrease the speed of the vehicles.
