When is a driver expected to cease all vehicle movement?

A driver is expected to cease all vehicle movement when directed by a police officer. This is crucial for maintaining safety and order on the road. Police officers are responsible for directing traffic, especially in situations where there may be accidents, roadworks, or emergencies. When an officer signals for a vehicle to stop, it ensures that the situation can be effectively managed, preventing further incidents and ensuring the safety of all road users.

In contrast, while a driver should be cautious when approaching a school zone or merging onto a highway, they are not required to stop completely unless specifically instructed to do so. Similarly, a green traffic light indicates it is safe to proceed, thus not requiring a cessation of movement. These distinctions underscore the importance of following direct instructions from law enforcement, which take precedence in ensuring public safety.
