Who can over-rule a traffic signal?

A crossing guard has a specific role in directing pedestrian traffic and ensuring the safety of children and other individuals crossing the street. During their duty, they are authorized to override traffic signals in order to assist pedestrians in crossing safely. This authority is granted to ensure that pedestrian safety is prioritized, especially in school zones where children may be present.

Other individuals, such as school bus drivers, traffic light technicians, and firefighters, have their own responsibilities but do not have the authority to override traffic signals in the same manner. School bus drivers must adhere to traffic laws while picking up or dropping off passengers. Traffic light technicians are responsible for the maintenance and functioning of traffic lights, not for managing traffic flow directly. Firefighters can request that traffic clears the way for emergency vehicles, but they do not have the direct ability to overrule signals like a crossing guard does when executing their duties.
