A speed hump is not the same as a speed bump.
- Speed humps are wider, put in local roads, and slow drivers to around 30 to 35 km/h to drive over them.
- Speed bumps are narrower, put in parking lots, and slow drivers to a near stop to drive over them.
Speed bumps are 80 millimetres (3 inches) high and 4 metres (13 feet) long.
Choosing the right location for a speed hump
Speed humps work best when they're designed and spaced appropriately. They're usually spaced
- 125 to 225 metres apart on local roads, and
- 60 to 100 metres apart on lanes.
When we're deciding where to put in a speed hump, we also look at
- manholes and catch basins
- grade of road
- road alignment
- length of road
- road shoulder or curb
Funding for speed humps
Funding for speed humps comes from Surrey's traffic calming program. Speed humps cost around $2000 to $3000 each.
Advantages of speed humps

- Potential for an increase in traffic noise and vibration
- Discomfort for local residents who must travel over them every day
