Who can direct traffic on the roads?

The correct answer indicates that school crossing guards, police officers, and flaggers all have the authority to direct traffic on the roads. This is because these individuals are specifically trained or designated to manage traffic flow to ensure safety.

Police officers are equipped with the necessary training and authority to regulate traffic conditions, including directing vehicles and pedestrians. School crossing guards help facilitate safe crossing for children near schools, particularly during busy drop-off and pick-up times, and they also play a critical role in ensuring pedestrian safety. Flaggers are often present at construction sites where traffic patterns are altered, using hand signals or flags to direct vehicles safely through the area while work is being conducted.

The other choices do not provide a comprehensive understanding of who can direct traffic. While some may suggest restrictions, the reality is that various trained personnel contribute to traffic management in different contexts, underscoring the collaborative effort required to maintain road safety.
