Road tunnel signs
These lane control signs will be found above each traffic lane at, or on, the approach to the entrance to a road tunnel and at regular intervals inside a road tunnel. When the signs are operational, the amber lights at the top, and at the bottom, will flash in turn.
A green arrow pointing down means the lane is open and it is permitted to proceed in that lane.

Go (lane open)
A red X means the lane is closed. You must stop. You must not pass this sign. It has the same effect as a stop sign.

Stop (lane closed)
A green arrow pointing to the left means you must move into the left-hand lane. In doing so you must observe the general rules of the road relating to safely changing lanes.

Move into the left-hand lane
A green arrow pointing to the right means you must move into the right-hand lane. In doing so you must observe the general rules of the road relating to safely changing lanes.

Move into the right-hand lane
The following sign means that goods vehicles and large non-passenger vehicles with three or more axles cannot use the right-hand lane of the carriageway. You must travel in the left-hand lane of the carriageways in a road tunnel.

In a tunnel goods vehicles cannot use right-hand lane (by reference to number of axles)
The regulation does not apply when:
There are two forms of speed limit signs in tunnels.
