Minnesota has hit the 300-mark for traffic deaths earlier than any year since 2007 — and officials say speeding is a major contributor, along with motorists who don’t buckle up.  Mike Hanson with the state Office of Traffic Safety says nearly all traffic fatalities are preventable, and mindset has a lot to do with it:

“That roadway isn’t meant for any individual to use as their own private playground….  It’s a cooperative venture and, when people don’t cooperate, when they bend or break the rules, that’s when tragedies happen.”

Hanson is urging motorists to focus on job number one — driving — as the state gets ready for another high-travel holiday — Labor Day weekend.
