AUSTIN, Texas -- Thousands of new signs are going up to remind drivers in Texas of "Left Lane for Passing Only" laws on highways with 75 mph or higher speed limits.
The Texas Department of Transportation on Friday announced plans to post about 3,400 additional signs by next summer in a renewed safety effort.
The 2011 Legislature approved 85 mph limits for some new stretches of road. Part of a toll road in the Austin area opens Oct. 24 with an 85 mph speed limit.
TxDOT official Carol Rawson says the left lane-passing signs are meant to help travelers have a safe, efficient and enjoyable trip.
Agency officials Friday did not immediately provide information on the current number of left lane-passing signs.
