What should remain activated during a traffic stop to warn oncoming traffic?

During a traffic stop, it is essential for emergency lights to remain activated to warn oncoming traffic. Emergency lights serve a critical function by making the stopped vehicle highly visible to other drivers, thereby promoting safety on the road. This visibility is especially important during low-light conditions or in areas with high speeds.

The use of emergency lights alerts motorists that there is a police presence and that they should proceed with caution. This is crucial not only for the safety of the officer conducting the stop but also for the safety of the individuals in the stopped vehicle and any passing traffic.

Although sirens can also be used to alert traffic, they primarily serve to signal immediate attention to stop or yield, rather than to provide ongoing warning during the stop. Traffic flares could provide warning as well, but they require setup and are not as effective for prolonged stops as emergency lights that are integrated into the vehicle. Hazard lights might signal a warning from a vehicle that is disabled or an emergency situation but are not specifically designed for police presence and do not provide the same degree of visibility or indication of authority as emergency lights do.
