The fastest posted speed limit in the country can be found in the Lone Star State. Texans are familiar with driving on roadways with 70 or 75-mph speed limits. There are even a few sections of highways where 80 mph is the maximum speed. However, the fastest posted speed limit in the country of 85 mph is only found in a certain stretch of Texas highway. State Highway 130 between State Highway 45 in Austin and Interstate 10 in Seguin is where drivers can legally drive 85 mph. The 85 mph segment runs about 41 miles. The stretch of speedy highway passes through towns such as Mustang Ridge, Mendoza, and Lockhart.
