Warning for Bridge
The sign indicates an opening bridge.
When You See This Sign
When you see the sign, slow down and be prepared to stop. Look for flashing lights, barriers and instructions, and only pass when it is clear and safe to do so.
Rules & Regulations
- The sign warns that a movable bridge is ahead; reduce your speed and be prepared to stop.
- Always obey traffic signals, flashing lights and any barriers at the bridge; do not pass when a red light is shown or the barriers are down.
- Do not stop or park on the bridge or its approaches in a way that would obstruct opening or passage.
- Show extra consideration when queues form and follow any instructions from traffic controllers or road markings at the bridge.
Tips for Drivers
- Brake in good time when you see the sign and scan the road ahead for vehicles that may stop suddenly.
- Keep a safe distance to the vehicle in front so you can stop safely if the bridge opens or the barriers come down.
- Look for warning lights, audible signals and barriers before passing — never pass on a red light or when a barrier is lowered.
- Be extra careful in darkness, fog or poor visibility as signals and obstacles may be harder to detect.
Common Mistakes
- Thinking the sign warns of low bridge clearance rather than that the bridge can open.
- Continuing to pass despite flashing red lights or lowered barriers.
- Stopping or parking too close to the bridge and thus obstructing the opening mechanism or space for crossing traffic.

Did You Know?
The sign is often used at bascule, swing and lift bridges in archipelagos and at major canals where boat traffic regularly requires the bridge to be opened.
Frequently Asked Questions
Do I always have to stop when I see the sign?
No, the sign is a warning and you should reduce speed and be prepared to stop. However, you must stop if a red light is shown or the barriers are down.
What do I do if I'm already on the bridge when it starts to open?
You should avoid being on a movable bridge when it opens. If you are accidentally on the bridge, drive off as quickly and safely as possible and follow any instructions from traffic personnel.
Does the rule also apply to cyclists and pedestrians?
Yes, all road users are covered by the warning and any signals at the bridge. Cyclists and pedestrians must not pass when there is a risk of the bridge opening or when signals prohibit passage.
