Various features can be provided to slow down the speed of the traffic:

• Road humps
• Road narrowing’s, central islands and chicanes
• Mini roundabouts

Some traffic-calmed areas are indicated only by a 20 mph speed limit sign. This speed limit sign, in addition to advising the maximum speed limit, also indicates that there may be traffic calming features within the signed zone and these may not be individually signed. You should drive at a steady speed within the speed limit, and avoid frequent acceleration and deceleration within these areas.

You may come across ‘Road Humps’, they may be round or flat top humps that are laid across the carriageway. They may be used on roads where there is a speed limit of 30 mph or less. In some areas, the humps are in the form of ‘cushions’ which only cover part of the lane and are designed so that larger vehicles, especially buses, can straddle them. If these are provided outside 20 mph zones, there will normally be:

• Warning signs at the beginning of the section of road where the hump or series of humps are installed

• Triangle and edge line-markings at each hump. Roads may become narrowed by the use of ‘build-outs’ on one or both sides of the road. If these are provided outside 20 mph zones there will normally be.

• Warning signs indicating which side of the road narrowing occurs.
