 DPS asking drivers to be careful on the roadways this holiday weekend, cautioning them to avoid driving mistakes that can turn a happy holiday into a tragedy. To watch their speed, make sure they're putting their seatbelts on, reduce the distractions, don't drive impaired by drugs or alcohol. Highway Patrol Sergeant Brad Cutler says they'd like to see a repeat of last year when there were no fatalities on Arizona's highways on the 4th of July.
