Road signs forcing truck drivers to use only the right lane cropped up this week along Interstate 12 in Livingston Parish as part of a push by State Police to decrease aggressive driving in the construction-heavy area.

The increased policing effort comes in response to several traffic-snarling crashes and increased reports of drivers speeding, swerving and not paying attention behind the wheel along I-12 generally between Walker and Livingston, said Trooper 1st Class Jared Sandifer, a State Police spokesman.

The Department of Transportation and Development said it installed 15 of the new road signs, which read “trucks use right lane only,” in the area of I-12 where construction crews have been working since November to widen the roadway from four lanes to six lanes.

There are several state laws that troopers could cite to issue tickets for violators of the new rule, Sandifer said, most notably Revised Statute 32:56, which forces drivers to obey traffic control devices in general.

But both State Police and DOTD agree that truckers don’t deserve all the blame for traffic problems in the area.

“This is not just about 18-wheelers,” Sandifer said. “We’re going to be looking for aggressive drivers.”
