Proceed
The sign indicates that you are allowed to proceed
When You See This Sign
When you see the police signal 'Drive forward' (P4) it means you may drive forward in the direction the officer indicates. Adjust your speed and check that the road is clear of pedestrians, cyclists, and obstacles before you continue. If the signal is not directed at you or if the officer changes the signal, wait and follow the new instruction.
Rules & Regulations
- The police signal takes precedence over traffic signals and road signs; when you receive P4 you must follow the police officer's instruction rather than traffic lights or road signs.
- P4 gives permission to drive forward in the direction the officer indicates, but the signal applies only to the vehicles or directions the officer is signaling to.
- You must adjust your speed and first check that it is safe to proceed — permission from the police does not automatically give the right to drive without regard for other road users.
- If the officer immediately changes the signal or another officer gives conflicting instructions, you must immediately comply with the new signal.
Tips for Drivers
- Look carefully at whom the officer is signaling to — arm direction and body language show whether P4 applies to your lane or only to certain vehicles.
- Reduce speed before you move forward and check for pedestrians, cyclists, and crossing traffic even after you have been given P4.
- Be prepared to stop if the officer changes the signal or if other road users act unexpectedly; act calmly and clearly.
- If you are unsure whether the signal applies to you, wait for a clear signal from the officer rather than driving in uncertainty.
Common Mistakes
- Believing that P4 automatically applies to everyone in the intersection — the signal may be directed only at one lane or a specific direction.
- Ignoring pedestrians or cyclists after receiving P4, even though you must check that it is safe before you proceed.
- Following the signal without checking for obstacles or accidents in your path — permission does not mean a free pass without risk assessment.

Exam Tip
On the theory test you may get a question where the police signal conflicts with the traffic light; the correct answer is that you should follow the police signal (P4) but still first make sure it is safe to drive forward.
Did You Know?
P4 is one of the standardized police signals in Sweden, and police signals have historically been used to direct traffic at accidents, events, and temporary stops — they have had precedence over traffic lights for a long time.
Frequently Asked Questions
Does P4 also apply at traffic lights?
Yes. The police signal takes precedence over traffic lights and road signs. However, you must always check that it is safe before you continue.
Does the signal apply to all lanes in the intersection?
No. P4 applies only to the vehicles or directions the officer is actually signaling to. Check the officer's arm direction and position to know if the signal applies to you.
Must I drive immediately when I get P4?
No, you may drive forward but must first ensure that the road is clear of pedestrians, cyclists, and other obstacles. If you are unsure, wait for a clearer signal.
What happens if I do not follow the police signal?
Failing to follow police signals is a violation of traffic rules and can lead to penalties and increase the risk of accidents. It can also create dangerous situations for other road users.
