If you are waiting a red light and police officer signals for you to keep driving, you should keep driving as a police officer's signal has the highest priority.

If you are driving and encounter several instructions at the same time, the following order of priority applies:

1. Police officer's signal
2. Traffic signals (light and sound signals)
3. Road signs
4. General traffic rules (for example the priority to the right-rule)

It is called "police officer's signal", but the following occupational groups also have the authority to direct traffic:

• Vehicle inspectors
• Escorts for wide, long and heavy loads
• Customs officials
• Traffic wardens (parking officers)
• Road workers with a red flag
• Other persons appointed by an authority to direct traffic
