Under what circumstance can utility service vehicles utilize flashing amber lights?

Utility service vehicles are authorized to utilize flashing amber lights primarily to increase visibility and alert other road users to their presence, especially during situations that may pose a potential risk. Flashing amber lights are commonly deployed in scenarios involving emergencies, as these lights signify caution and a need for other drivers to exercise caution around these vehicles.

In the context of emergencies, the visibility provided by these lights plays a crucial role in ensuring the safety of both the utility workers and other motorists, as they may be undertaking tasks that could disrupt normal traffic flow or pose hazards. Although utility service vehicles might engage in maintenance or other operations, the key circumstance that allows for the use of flashing amber lights centers around the nature of those activities related to emergency responses.

The other situations, such as performing regular maintenance or being parked on the side of the road, may not justify the use of flashing amber lights in the same way that emergencies do, as they might not always present the same urgent need for heightened visibility and caution. It is essential for drivers to recognize that the presence of flashing amber lights is primarily a signal of an emergency scenario requiring careful attention.
