What it means
Reserved lane for public transport vehicles including buses, trams, and minibuses. Private cars are forbidden.
What to do
- If you are not driving a bus, tram, or minibus, stay out of the marked lane or area.
- Check the sign for operating times; outside them the lane is usually open to all.
- Tram rails in the lane are slippery when wet; other traffic keeps clear anyway.
In the K53 test
Blue circle means command: the lane belongs to a bus, tram, or minibus while the sign applies. Using a reserved lane to jump a queue is the offence being tested.
Where you will see it
