A police signalling disc is displayed towards you from a vehicle driving in front of you. What does this mean?

When a police signalling disc is displayed from a vehicle in front of you, it indicates that you must follow the commands of the police. This means you should comply with two key aspects:

1. You have to follow the vehicle until it comes to a complete stop. This is important for maintaining order and ensuring safety during police operations.
2. You may not overtake the vehicle because the police may need to control traffic or manage a situation ahead.

The third option, which states you must turn in a specific direction indicated, is not applicable in this context. The focus of the police signaling disc is on following and not overtaking, which is crucial for allowing the police to carry out their duties effectively.

Understanding these rules helps promote safety and cooperation on the road when law enforcement is involved.
