1. Speed cushion

A speed cushion is a type of traffic calming device — similar to a speed hump — but with gaps in between so that emergency vehicles like fire trucks or ambulances can pass through without slowing down, while regular cars still have to slow down.

  • Cars have to slow down because their wheels hit the bumps.
  • Buses or emergency vehicles (with wider wheelbases) can straddle the gaps and avoid the bumps.
  • This way, traffic is calmed without delaying emergency services.
