Missouri State Highway Patrol officials are hoping this year’s numbers of those killed and injured on Missouri’s roads for the Fourth of July holiday weekend are much lower than a year ago. Those numbers showed more than 1,200 crashes with 20 people dead and 621 injured. Patrol Spokesman Lieutenant Tim Hull says they’ll start counting Friday night through late Monday night. Hull says driver inattention still remains the number one cause of accidents while drinking and driving and speeding take their tolls as well. He encourages everyone in a vehicle to buckle up this weekend. Hull says the patrol will be out in full force this weekend, watching.
