What it means
Command: Route reserved for vehicles with dimensions or loads exceeding legal limits. Usually includes escort vehicles.
What to do
- If you are not driving an abnormal-load vehicle, stay out of the marked lane or area.
- Check the sign for operating times; outside them the lane is usually open to all.
- Expect escorted, very slow, very wide loads where this applies.
In the K53 test
Blue circle means command: the lane belongs to an abnormal-load vehicle while the sign applies. Using a reserved lane to jump a queue is the offence being tested.
