They also assist with state road accidents when delays in clearing the roadway would cause undue traffic problems. On call 24 hours a day, the division is called upon to handle all fatalities on parish road and, again, if a state unit is not available, state roads. Traffic deputies also participate in public safety awareness programs such as seatbelt checkpoints and conducting mock accidents at area high schools.
Officers also conduct school zone traffic throughout the school year.
The division's two part-time deputies are responsible for handling funeral escorts within St. Charles Parish. All funeral escorts within the parish are provided free of charge.
