Here’s a mantra you may repeat to yourself in Austin traffic (likely in-between bouts of profanity): The left lane is for passing only.
Despite the fact that passing on the left is the safest practice (and the fact that Texas has prohibitions against passing on the right), it’s a practice that’s routinely disregarded – just ask any Central Texas motorist.
The Texas Department of Transportation (TXDoT) is trying to do something about that, by installing a little reminder on Texas highways: some 3,400 signs stating “Left Lane for Passing Only.”
Before you get your hopes up, here’s the rub – they’re only going up on highways with speed limits over 75 mph. That excludes Mopac and Interstate 35 as they cut through most of Central Austin.
