Motorway signs, signals and road markings
Symbol signed diversion routes”. Sometimes There is a need to close a section of road, perhaps because of an accident, or as part of the work to improve or maintain the road network. As you are diverted off the road you will see the diversion sign with a symbol next to it. Different symbols indicate different routes, so be sure to keep following the same symbol, for an introduction to the system the Highways Agency has produced this video
Most motorway signs have a blue background with white lettering, numbers and borders, although tourist destination signs,as on other roads, have brown backgrounds
To ensure that direction signs are absolutely clear to drivers travelling at motorway speeds, it is necessary to limit the number of destinations shown. Your destination might not appear on the motorway signs: when planning a journey, it is advisable before setting off to check the junction number of the exit you require. Junctions can be identified by the number shown on a black background in the bottom left-hand or top left-hand corner of motorway signs (or, in the case of overhead signs, in a separate panel also indicating the distance to the junction). Junction numbers are usually shown on road maps, so it is easy to check these before starting your journey. On the motorway, these numbers can be used as a guide to your location. However, not all junctions have an exit in both directions, so numbers may not be consecutive. Where new junctions have been constructed, the number may be followed by a letter
A road other than a motorway is called an "all-purpose road". At the point where you join a motorway, a special symbol is used to indicate the start of motorway regulations. A direction sign on an all-purpose road will normally use this symbol to indicate a motorway slip road or the beginning of a motorway.
Where a sign shows a motorway route number on a blue background without the symbol, the route indicated will normally be an all-purpose road that you should follow to reach the motorway.
Blue direction signs, with the motorway symbol and large route numbers, indicate that a motorway or motorway slip road leads directly from a junction with an all-purpose road.
The motorway junction number, shown on the black background, may not always be included
On the approach to a junction with a motorway, a direction sign on an all-purpose road has blue panels that include the motorway symbol. The panels may include the junction number on a black background. The name in capital letters is a regional destination
This sign, with the motorway number in brackets on a blue background, but without the motorway symbol, indicates the route to take from a junction ahead in order to reach the motorway.
The motorway is not accessed directly from this junction
Signs for junctions on the motorway
On the approach to a junction, direction signs are usually located 1 mile and 1/2 mile in advance, and at the exit point. Where junctions are close together, these distances may be reduced,normally to 2/3 mile and 1/3 mile respectively. The signs may be mounted at the side of the road or overhead.
Signs located at the side of the motorway. These are used where there is a deceleration lane. The number of lanes through the junction remains the same
|The first two signs on the approach to a junction show the destination and the route number for the exit only. The distance shown (usually 1 mile or ˝ mile) is the distance to the exit (start of the deceleration lane). The junction number is shown on the black background||This sign is located at the start of the deceleration lane and includes destinations reached by staying on the motorway||A final route direction sign is usually located where the exit slip road separates from the main carriageway|
|Countdown markers indicate the distance to the start of the deceleration lane. Each bar represents about 100 yards|
Overhead sign for junctions with deceleration lanes, where the number of lanes through the junction remains the same
This sign is used on the approach to the junction (usually 1 mile and˝ mile in advance) and at the start of the deceleration lane. Destinations and route numbers are shown for both the exit and the motorway ahead. Countdown markers are normally provided for the deceleration lane
Signs located at the side of the motorway where one or more lanes leave the main carriageway to become the exit slip road. This type of junction is known as a lane drop
sign is normally located 1 mile and ˝ mile before the junction and
shows the appropriate lanes to use for various destinations. In this
example, the left-hand lane leads directly to the exit slip road;
the centre and right-hand lanes continue through the junction
This sign, with the inclined arrow, is normally located just before the left-hand lane leaves the main carriageway
Overhead signs for a lane-drop junction
A confirmatory sign may be provided just after the point where the slip road has separated from the main carriageway. It is used where signs on the approach to the junction are either overhead or located at the side of the motorway
Lane-drop junctions do not use the countdown markers, as there is no deceleration lane for drivers to move into. A special road marking is used at lane drops between the main carriageway and the lane that leads to the exit slip road. This marking usually commences at the 1/2 mile advance sign.
Some junction layouts may be more complex and designed to allow a heavier flow of traffic to leave the motorway. A traffic lane may be shared by traffic both continuing ahead and leaving the motorway.
This shared lane has a deceleration lane separated from a lane drop by chevron road markings. In the example, the left-hand lane is used for the exit slip road only, the centre lane is the shared lane, and the right-hand lane is for ahead traffic only.
A sign mounted at the side of the motorway shows the road layout. An overhead sign shows the appropriate lanes to use for each destination.
A sign mounted at the side of the motorway shows the arrangement of traffic lanes Central
Overhead sign showing appropriate lanes for the different destinations
Other types of sign in advance of junctions
Where two junctions are very close, they may both be shown on the same sign, together with the distances and junction numbers. The sign that is located where the deceleration lane starts for the first exit will normally show the second exit place names and route number with the ahead destinations
This overhead sign indicates a junction that has two exits. The first exit has a deceleration lane and is indicated by the upper part of the sign. The second exit is a lane drop. Traffic continuing along the motorway should use the centre and right-hand lanes
Signs showing lanes that join the main carriageway at junctions
slip road joins the main carriageway as a lane gain to increase the
number of lanes from two to three. A distance panel may be added
The right-hand lane of the slip road joins the main carriageway as a merge with an acceleration lane. This is followed by the left-hand lane which joins the main carriageway as a lane gain. Chevron road markings normally separate the two lanes on the slip road. The distance may be omitted
Direction signs on exit slip roads (the green panels indicate a primary route; the white panels indicate a non-primary route)
Direction signs where the main carriageway of a motorway ends at a roundabout
Motorway ends at a junction with an all-purpose road
Motorway ends at a junction with another motorway
Signs for tourist destinations
Tourist destinations are shown on signs with brown backgrounds. On the main carriageway of a motorway, these are separate from the main direction signs and are usually sited 3/4 mile and 1/4 mile from the junction (although they do not show the distance to the junction). On exit slip roads and where the motorway ends at around about, the main direction signs may show tourist destinations on a brown panel, in the same way that they show other destinations on green and white panels (see page 83).However, separate brown signs are likely to be used at these locations to avoid putting too much information on a single sign. See pages 100 to 102 for more information about tourist signs.
Where it is not practicable to provide tourist destination signs within 1 mile of a junction or there are more destinations than can be accommodated on the signs, this sign maybe used in advance of the main 1 mile direction sign for the junction. It may also be used when the junction layout is complex "leave at Junction 24"is then varied to "follow" plus a destination
Signs for motorway service areas
On most motorways, service areas are provided at intervals of not more than 30 miles, half an hour at normal motorway driving speeds. These service areas are open 24 hours a day, every day of the year, and provide fuel, free parking (up to 2 hours),refreshments, toilets and disabled access. Other facilities, including telephones, motels and tourist information, may also be provided. Some motorway service areas are accessed directly from the main carriageway, others via junctions with other roads,where they will also be available to non-motorway traffic.
Alternative signs indicating the entrance to a service area accessed directly from a motorway. May be used to indicate the direction to a motorway service area located on an all-purpose road
Where a motorway service area is situated on an all-purpose road,the signs off the motorway,indicating the services, should have a blue background (older signs may have a green or white background). The geographical name of the services may be shown on these signs, but not the operator’s name (this is shown only on the signs on the motorway). The word "Services"may be incorporated into other direction signs, including the sign on the exit slip road from the motorway. Where these signs have a green or white background, the word "Services"(with or without a geographical name) will normally be placed on a blue panel.
Signs may be provided to indicate that services are not available on the motorway.
Sign on motorway indicating that no services are available ahead. Drivers should leave the motorway if service facilities are required
Sign on all-purpose road indicating that no services are available on motorway ahead. The motorway number may include a compass point (e.g. "M 41(N)") if services are available in one direction but not the other
Other signs on motorways
A route confirmatory sign is provided after most junctions. This shows the motorway number and the distances to the main destinations ahead
Where there are more destinations than can be accommodated on the direction signs at a junction, a sign such as this may be used in advance of the 1 mile direction sign. It advises drivers of the route to be followed (or junction to leave at) for destinations that cannot be accommodated on the main junction sign
This sign indicates a slip road that leads to a maintenance compound and is not available to the general public
Where a motorway has been widened but the original bridges retained, there may be no hard shoulder under or over the bridge. Where this occurs, signs will indicate the distance over which this applies. There will be hatched markings on the hard shoulder at the point where it comes to an end
Observation platforms are sometimes provided at the back of the hard shoulder. These are reserved for authorised vehicles, such as those of the Highways Agency's Traffic Officers or the police
Marker posts, located at the back of the hard shoulder at 100 metre intervals, show the direction to the nearest emergency telephone (housed in an orange box). You can use the telephone to contact the control centre in case of an emergency or breakdown
Direction signs for drivers of goods vehicles
Signs indicating the end of motorway regulations
|Sign located at the entrance to a service area accessed directly from the motorway, or a maintenance compound||Sign located on main carriageway to indicate the distance to the end of the motorway||Sign located where the motorway ends on either the main carriageway or exit slip road|
Motorway signals and variable signs
These advise of abnormal traffic conditions ahead (e.g. lane closures or fog) and may indicate a speed limit. Where variable speed limit signs are mounted over individual lanes and the speed limit is shown in a red ring , the limit is mandatory. Speed limits that do not include the red ring are the maximum speeds advised for the prevailing conditions.
Signals and variable signs may apply to individual lanes when mounted overhead or, when located on the central reservation or at the side of the motorway, to the whole carriageway. They are normally blank, but when they indicate a restriction the reason may not always be obvious. There may have been an accident ahead, so take no chances and obey the signals. When red lamps are flashing above your lane, you MUST STOP unless you can move safely to a lane where red signals are not showing.
Lamps flashing from side to side in pairs, together with a red cross, mean"do not proceed in the traffic lane directly below". These signals are mounted above the carriageway: there is a signal for each traffic lane. A previous signal may direct you into an adjacent lane . More than one lane may be closed to traffic
Signals and variable signs above each lane of the motorway
Signals and variable signs at the side of the motorway
These apply to the carriageway as a whole and are either located on the central reservation or mounted above the hard shoulder in combination with variable signs that display information about road works, congestion and diversions ahead. The amber lamps flash in pairs from top to bottom
All lanes closed (signs for carriageways with four, three or two lanes). Do not enter the motorway when the red lamps are flashing in pairs from side to side
Older type of motorway signal
On some motorways, particularly in Scotland, you may encounter this type of signal mounted at the side of the carriageway. Flashing amber lamps indicate that there is a hazard ahead. You should not exceed a speed of 30 mph until you have passed this hazard
