Which vehicles are typically equipped with amber flashing beacons on the roof?

Amber flashing beacons are commonly used on vehicles that are involved in activities where visibility and caution are essential, such as maintenance operations on roads and highways. These vehicles are often engaged in tasks that could pose a risk to both the crew working on the road and passing drivers. The use of an amber beacon serves to alert other road users to exercise caution and be aware of potential hazards ahead, such as slow-moving or stationary work zones.

Emergency response vehicles typically use red and blue flashing lights to signify urgency and the need for other vehicles to yield. Passenger taxis often have a designated light but do not generally use amber flashing beacons, and private cars do not require such warning systems as they do not typically operate in scenarios that necessitate extra caution for other road users. Thus, maintenance vehicles are the ones that appropriately utilize amber flashing beacons to ensure safety in their operational environment.
