When can flares be used in traffic control?

Flares can play a vital role in traffic control, particularly during emergencies when visibility is low or as a temporary caution indicator. They are designed to enhance safety by providing a visible warning to drivers in situations where conditions may be hazardous, such as accidents, breakdowns, or adverse weather conditions. The bright light emitted by flares makes them effective in alerting drivers to potential dangers, serving to reduce the risk of collisions.

While flares may be seen in various situations, their primary use is centered around emergencies requiring immediate attention. They are not restricted to only nighttime use, making them versatile tools under varying visibility conditions. Furthermore, while law enforcement may utilize flares, their use is not exclusive to scenarios where police presence is indicated; hence, they can be employed effectively by traffic control personnel without waiting for such advisement. Their practicality during emergencies underscores the importance of understanding the appropriate contexts for flare deployment in traffic management.
