What do blue motorway signs with lines on them mean?
Motorways are one of the most daunting parts of learning to drive. It’s no surprise that many people don’t know what everything means.
The blue-lined signs on the motorway are countdown markers to the next exits. The first is 270 metres from the start of the slip road and the rest are positioned 90 meters apart. Before you approach the slip road, merge into the left lane.
