TxDOT is getting ready raise the speed limit on Lubbock area roadways. A new state law takes effect on September 1st which allows three major changes.
The nighttime speed limit will now be the same as the daytime speed limit. The truck speed limit will be the same as other vehicles. And, where safety allows, the speed limit will go as high as 75.
Interstate 27 will be studied first. Who determines if 75 is a safe speed on the Interstate? Well, to a large extent, drivers do.
"Drivers will drive typically the speed limit they feel comfortable with," says Director of Transportation Operations in the Lubbock office of TXDot, Frank Phillips.
"We put counters out to get data," Phillips says. "From that we look at all the speeds, typically every two miles."
TxDOT uses a method called the 85 percentile. It's the speed at which most, but not all drivers, go.
"It's all about what the driving public feels comfortable driving. Drivers will drive typically the speed limit they feel comfortable with."
Phillips says it will take about two years for a contractor to study all the major routes in the Lubbock area. Interstates, federal highways, state highways, and even two lane roads are all treated the same in terms of determining the speed limit.
The new law also allows 85 miles, per hour but Phillips says no roads in the greater Lubbock area will qualify for that particular speed limit.
