Should children be required to wear reflective vests at school bus stops? That’s the opinion of a South Carolina man after he was involved in a tragic incident last month.

At 6:30 in the morning, a 15 year old girl, escorting her younger siblings to school, tried to cross a four lane highway. Wearing dark clothes and crossing away from an intersection, she was struck first by a semi and then struck again as she was lying in the roadway. Police didn’t charge either driver because they felt there was little either driver could do to avoid hitting her.

Torn by the incident, the driver of the second vehicle wrote a letter to his state representative asking for a law that would require children at school bus stops to wear reflective vests.

His proposal isn’t a bad idea. While it may not be necessary for the state to pass a law, it is certainly something that school boards should encourage and parents can easily do on their own. With the time change last month, many kids are heading out to school while it’s still dark. Kids are impulsive and don’t always follow the rules. Anything that can be done to make them more visible is a good idea.

A quick search for children’s reflective vests on Google shows a wide variety of vests from $5 to $15. A cheap price to make the kids more visible. Reflective tape can also be sewn or pasted on backpacks at a very low cost.
