What it means
This lane is reserved for the exclusive use of buses and trams to facilitate public transport flow.
What to do
- If you are not driving a bus or tram, stay out of the marked lane or area.
- Check the sign for operating times; outside them the lane is usually open to all.
- Never stop in the shared lane; trams cannot steer around you.
In the K53 test
Blue circle means command: the lane belongs to a bus or tram while the sign applies. Using a reserved lane to jump a queue is the offence being tested.
