Priority vehicle

All road users must yield to priority vehicles without creating a dangerous situation. For example, ignoring a red traffic light or using an emergency lane is prohibited!

A vehicle is only considered a priority vehicle if it is simultaneously displaying both blue visual and audible signals. If either of these signals is missing, it is not a priority vehicle.

Sometimes priority vehicles weave through traffic. You must then create space to allow the priority vehicle to pass.
You can do this by, for example, swerving to the left or right.
First, you must check the direction from which the priority vehicle is approaching. Then, for safety reasons, you must determine the best course of action to create space as safely as possible. Adjust your speed if necessary. It is also important to pay attention to other road users. When everyone is swerving to the right, you must follow them. When everyone is swerving to the left, you must also swerve to the left. This also gives the driver of a priority vehicle a clear indication of where they can proceed most safely. You must do this without violating traffic regulations or causing danger.
