Motorway signals and variable signs
Stop Road Closed
These advise of abnormal traffic conditions ahead (e.g. lane closures or fog) and may indicate a speed limit or provide journey time information. Where variable speed limit signs are mounted over individual lanes or at the side of the motorway and the speed limit is shown in a red circle, the limit is mandatory. Speed limits that are not shown in a red circle are the maximum speeds advised for the prevailing conditions. Signals and variable message 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 lights are flashing above your lane, you must stop unless you can move safely to a lane where red signals are not showing.
Where red flashing light signals and closure of all lanes are shown on a sign, the road is closed. You must not go beyond the sign in any lane or use the hard shoulder to avoid the road closure unless directed to do so by a police or traffic officer.
