Speed humps are asphalt mounds placed on roadways for the purpose of slowing traffic.
Speed humps are different than speed bumps, which are commonly seen in parking lots or on private streets. The City of Phoenix only allows speed humps on public streets. Unlike traditional police enforcement, speed humps provide continuous service. They may also help discourage cut-through traffic by diverting it elsewhere. Vehicles may drive on sidewalks or through front yards to avoid speed humps.
