Red and Amber Flashing Lights on the Motorway

Red flashing lights mean you must not proceed in the lane or lanes it applies too.

Amber flashing lights warn of a hazard ahead.

These signals will be situated above each lane, on the central reservation or at an entrance to the motorway.

Signals on the central reservation apply to all lanes and signals above are separate for each lane.

With the amber flashing lights signals will indicate a temporary hazard like reduced speed limit, fog, ice, change lane or leave motorway at next exit.

With the red flashing lights signals and a red cross, do not proceed in that lane. Red flashing lights and white T-shapes: do not enter the motorway.
