Road Signs
Traffic Calming Signs
Traffic calming is the term used to describe physical features provided along a road to encourage drivers to reduce speed. These features are introduced for the safety of all road users,particularly pedestrians and cyclists. Traffic calming schemes can employ a variety of measures, including road humps and narrowings. Warning signs often indicate the type of measure to be expected. There may be an entry sign at the boundary of an area that has traffic calming features

Entrance to a traffic-calmed area. The name of the area may be shown. The sign may also be used in advance of the area and show a distance. Where the traffic-calmed area is reached by turning into a side road, the sign will include an arrow |

humps
Road humps may have a flat or round top, extending across the width
of the road or covering a whole junction. They may also be in the
form of a "cushion", covering only part of a traffic lane and designed
to allow buses and large emergency vehicles to straddle them, whilst
slowing other vehicles. Except in a 20 mph zone, warning signs are
erected at the beginning of the road where a hump or series of humps
is installed.

A road hump is normally marked with white triangle and edge line markings.

Road narrowings
Roads may be reduced in width by the use of build-outs on one or both sides. When placed on both sides, they may be opposite each other or staggered. Priority through the narrowing may be controlled by signs and "give way" markings. It is essential that you obey signs indicating priority to vehicles coming from the opposite direction.

If priority is not given to either direction at a road narrowing, you should ensure that you can pass through without endangering occupants in vehicles approaching from the other direction. Do not accelerate on the approach to a narrowing, but maintain as low steady speed and be prepared to give way to approaching traffic. Let any cyclists proceed ahead of you.

Home Zones


Home Zones are residential areas with streets designed to be places for people aswell as for motor traffic. The road space is shared among drivers and other road users. People could be using the Entrance to a Home Zone 20 mph zones Some traffic-calmed areas are indicated by the 20 mph zone entry sign. This sign, aswell as indicating a 20 mph speed limit, warns drivers that they are entering an area with traffic calming features, such as road humps and road narrowings. These features may not be individually signed, nor are there likely to be 20 mph speed limit repeater signs. In these areas, it is important that you adopt a steady low speed and avoid repeated acceleration and deceleration. Entrance to a 20 mph zone End of 20 mph zone and start of 30 mph speed limit 75 whole of the space for a range of activities. You should drive slowly and carefully and be prepared to stop to allow people extra time to make room for you to pass them in safety.
Quiet Lanes
Some minor rural roads may be designated as Quiet Lanes. These are appropriate for shared use by walkers, cyclists, horse riders and motor vehicles. You should drive slowly and carefully and be prepared to stop to allow people extra time to make room for you to pass them in safety.

Other features
Rumble devices across the road, either in the form of strips or
larger areas, may be used to provide a visual, audible and vibratory
effect, often in rural locations. The intention is to alert drivers
to a hazard ahead, usually a bend or road junction, and encourage
them to reduce speed. A warning sign may be used in association
with a rumble device to identify the hazard, but the device itself
is not the hazard and is not usually specifically signed.
Gateways into villages may be formed from the combination of speed
limit signs, yellow backing boards and village name plates. Central
hatched markings or islands may also be used to separate opposing
traffic. Drivers approaching the gateway should reduce speed and
observe the speed limit all the way through the village.
Some parts of the carriageway may have a coloured surface to emphasise
the road markings.
