The Washington Post recently conducted an investigation into DC's traffic enforcement, and it turns out some of the worst traffic offenders in the District are city school bus drivers.

The school buses, driven by professionals whose sole job is to safely transport children, were caught speeding and running red lights hundreds of times over a four-year period.

According to the Post, DC operates a relatively small fleet of around 750 school buses, whose drivers have been caught on camera speeding and running red lights 347 times between 2009 and 2013.

Some drivers are repeat offenders, and the investigation found more than 20 drivers caught on traffic cameras were also involved in crashes. According to the Post, people were injured in four of those accidents.

No drivers were disciplined as a result of the tickets, and they collectively still owe the city around $13,000 in fines.

The Office of the State Superintendent of Education, which controls the city school bus fleet, recently began implementing changes that include the immediate termination of drivers caught speeding more than 15 miles over the speed limit.

"We know these things need to be taken care of, and now we have systems in place to do that," Solchenberger told the Post.
