Reduce Speed
The sign indicates that you should reduce your speed
When You See This Sign
When you see the police signal 'Reduce speed' you should immediately lower your speed to a safe level and adjust your driving to the traffic situation. Watch for further instructions from the police and be prepared to stop or follow other directions.
Rules & Regulations
- Reduce speed (P8) is a police signal that is binding — you must immediately reduce your speed and adapt your driving to the prevailing conditions.
- The signal applies to the direction toward which the police's gesture is directed and covers all vehicles affected by the signal.
- After you have reduced your speed you should be prepared to follow additional police orders, for example to stop, pull over to the side, or follow a designated diversion.
- Failure to follow the police signal can lead to a warning, fines, or, in serious cases, other legal consequences.
Tips for Drivers
- Brake gently and in a controlled manner when you see the signal — check your rearview mirrors to avoid being rear-ended.
- Slow down in good time so you can stop safely if the police give further instructions, for example to pull onto the roadside.
- Pay attention to who the police are directing the signal at (an entire lane, a specific vehicle, or traffic in one direction) so that you act correctly.
- At night the police may use an illuminated sign or a flashlight. Recognize the light pattern and respond in the same way as to the daytime signal.
Common Mistakes
- Thinking that the signal is only a recommendation — many fail to realize that it is legally binding.
- Braking suddenly without checking the mirrors, which increases the risk of being rear-ended.
- Confusing the police's 'Reduce speed' with a permanent speed limit sign and believing that a new official speed limit has been introduced.
