Tunnel marker
The sign is a tunnel marker and makes the course of the road or an obstacle clearer.
When you see the sign
Use the marking to read the road ahead and to see the tunnel wall or other obstacles more clearly. Adjust your speed and road position if the marking indicates that the road alignment changes direction or that the lateral clearance becomes narrower.
Rules
- Sign 914.H is a tunnel marking that makes the road alignment or an obstacle in a tunnel more clearly visible.
- The marking does not, in itself, require you to drive in a particular direction, give you priority, or impose a specific speed limit.
- The right-hand variant is used to mark the right side of the road or tunnel alignment.
- You must still follow lane markings, road markings and any mandatory, warning or prohibitory signs in the tunnel.
Tips
- Look along the line of markings to identify curves and changes in the tunnel alignment early.
- Keep a good distance from the right-hand tunnel wall, especially where the markings indicate reduced lateral clearance.
- Do not fix your gaze on a single marking; shift your focus further ahead along the road alignment.
- Be prepared for the marking to highlight a tunnel wall, tunnel portal or other fixed structure close to the carriageway.
Common misconceptions
- Some people think the marking means they are required to turn right. Its main purpose is to make the road alignment or an obstacle more clearly visible.
- The sign is often confused with an obstacle marker, where the diagonal stripes point down towards the side on which the obstacle can be passed.
- Some interpret the marking as indicating a speed limit, but it does not set a specific speed.
Test yourself
Easy
What does this marking mean?
- AIt clarifies the right side of the road's or tunnel's course.
- BIt sets a special speed limit through the tunnel.
- CIt requires all vehicles to turn right.
- DIt indicates that an obstruction may only be passed on the right side.
Medium
You are driving in a tunnel where the lane bends to the right. This marking is along the right side, and the speed limit is posted as 60 km/t. What do you do?
- AI drive to the right of the marking because the stripes determine the side to pass on.
- BI turn sharply right because the marking requires a particular direction of travel.
- CI follow the course of the lane and adjust my speed without exceeding 60 km/t.
- DI increase my speed to 80 km/t because the marking cancels the posted speed limit.
Hard
This marking is placed at an obstruction in a tunnel. What can you safely assume when choosing which side to pass on?
- AI must pass the obstruction on the right because the diagonal stripes determine the side to pass on.
- BI must pass the obstruction on the left because the marking is on the right side.
- CI may pass the obstruction on either side because the marking overrides other regulation.
- DI must use the lane, road markings and other signs to determine which side to pass on.
Theory test tip
In the theory test, the trap may be to choose that the diagonal stripes show which side an obstacle should be passed on. That is the meaning of specific obstacle markers; this sign is a tunnel marking that makes the road alignment or an obstacle more clearly visible.
Did you know
Tunnel markings are used because contrasts, distances and the curvature of the road can be more difficult to judge in artificial tunnel lighting. The right-hand variant helps make the right-hand boundary and the road's continuing alignment easier to perceive.
Frequently asked questions
Do I have to turn right when I see this marking?
No, the marking does not independently require you to turn. It helps you see the right side of the tunnel or road alignment.
Does the marking indicate which side an obstacle can be passed on?
Not in the same way as an obstacle marker with diagonal stripes. You must use road markings, signs and the actual layout of the carriageway to determine where to drive.
Does the sign mean that the speed limit is lower?
No, the tunnel marking does not change the speed limit. You must nevertheless adjust your speed to the visibility, curvature, tunnel width and other conditions.
Why is a separate marking used in tunnels?
In tunnels, the lighting conditions and uniform walls can make it more difficult to judge the road alignment and the distance to fixed structures. The marking provides better visual guidance and makes obstacles more noticeable.
