Drivers in Texas, Iowa, and Indiana will enjoy higher speed limits next month as legislation raising the top speeds on rural roads takes effect.

On Friday, Texas Governor Rick Perry (R) signed HB 2257 into law making 80 MPH the maximum allowable speed in the state. Rural portions of I-10 and I-20 will enjoy the new top speed, while other rural roads could see the limit rise to 75 MPH. Both the state House and Senate adopted the legislation without opposition last month.

On July 1, a law signed by Iowa Governor Tom Vilsack (D) creating a 70 MPH speed limit goes into effect. This new limit better reflects the actual speed of cars on rural highways which averages 69.8 MPH according to sensors embedded into the pavement.

In May, Indiana Governor Mitch Daniels (R) signed SB 217 into law raising the maximum limit from 65 MPH to 70 MPH in areas with less than 50,000 population. The law also raises the limit for trucks from 60 to 65 MPH, and gives a 10 MPH boost to several roads currently posted at 55 MPH. The state will begin placing the higher-limit signs on July 5.
