Canadian Boating Exam Practice Quiz

What color light is displayed by government or police vessels engaged in assistance or law enforcement duties?

1. Red flashing light

2. Blue flashing light

3. Yellow flashing light

4. Green flashing light

The correct answer is: Blue flashing light

Government or police vessels use a blue flashing light to display their presence during assistance or law enforcement duties. This helps to differentiate them from other vehicles and alert drivers to move aside and allow them to pass through. It is important to not confuse this with red flashing lights, which are typically used for emergency vehicles such as ambulances and fire trucks. Yellow and green flashing lights are not commonly used by government or police vessels and are more commonly seen on construction or maintenance vehicles. These colors may not have the same level of recognition or authority for drivers to yield to. Therefore, the use of blue flashing lights is the most effective and appropriate option for government or police vessels in these situations.
