The number of people killed on Missouri roads this year is up eight percent. Nearly 900 people have died in traffic crashes so far this year compared with just over 800 last year. Lieutenant Tim Hull with the State Highway Patrol says it’s hard to explain why the number of deaths is up and why drivers keep ignoring advice to wear their seat belts. Seven people died this weekend in traffic wrecks, a particularly bloody weekend. Hull says that points out that drivers much take precautions at all times – not just the long holiday weekends that get so much attention.
