Nebraska and Iowa have joined nine other states in raising traffic law enforcement along Interstate 80.
The Nebraska and Iowa State Patrols are increasing their presence and making more vehicle checks as part of the "I-80 Challenge." The extra efforts began Wednesday and run through the end of the month.
Safety experts say the last week of July is the deadliest time of year for crashes along I-80. Several state roads departments along I-80 are displaying messages on electronic boards reminding motorists to wear their seat belts, obey the speed limits, avoid cellphone use and pay attention. Also, don't drive drunk or otherwise impaired.
The interstate runs 2,900 miles, from the San Francisco to Teaneck, N.J.
