Colo. - Bus drivers in Colorado this year observed at least 575 cars illegally pass the bus stop sign in a one-week period, according to national survey.
"It is a big issue because last year there were a lot of children nationwide either killed or severely injured because someone ran a school bus stop arm," said David Hartzell, the director of transportation for the Harrison School District.
The survey was conducted by the National Association of State Directors of Pupil Transportation Services.
The flashing red and amber lights on school buses generally indicate you should stop 20 feet in front or behind the school bus.
Josy Campbell, the operations manager for the Harrison School District, said it's best if people err on the side of caution.
"If you're unsure of when or where to stop for a school bus, maybe it's just better to stop," Campbell said.
Last year, a driver in Indiana killed three siblings after passing the school bus' flashing stop sign.
"A child should never die trying to go to school," Hartzell said. "Unfortunately, it does happen."
In response to similar incidents, Campbell and other school administrators are working to add more information on school bus traffic laws in Colorado's driver's license guides.
"We didn't want to be a community that later said 'Oh shucks, we should have done something. We should have been more proactive,'" Hartzell said. "We'd rather be proactive than reactive."
