The Emergency and breakdown bay sign indicates a designated area where vehicles can stop in case of an emergency or breakdown. These bays are typically located along highways or busy roads to provide a safe space for drivers who need to pull over due to mechanical issues or other emergencies.

According to German traffic regulations, when you see this sign, it is a signal that you are approaching a portion of the road where you can safely stop your vehicle without obstructing traffic, provided that you have a legitimate reason such as a vehicle breakdown or an emergency.

It's important to use these bays only for their intended purpose. They should not be used for parking or resting unless it is an emergency situation. Always ensure that your vehicle is clearly visible to oncoming traffic when you use an emergency or breakdown bay, and remember to follow safety procedures when exiting your vehicle.
