LEE COUNTY, Miss. (WTVA) -- The Natchez Trace Parkway a two-lane highway, and there's very little room for error for drivers.
Park rangers say they are working to keep commercial vehicle drivers off the Natchez trace.
They said if they catch you, you could spend some time behind bars.
"We are actively looking for them, and we are enforcing that," said U.S. Park Ranger Timothy McElwain.
U.S. Park Rangers are now lying in wait for commercial vehicle drivers to take their chance on the Natchez Trace parkway.
"It's truck that takes up the entire lane width, and it's already a narrow roadway," said McElwain.
McElwain said this puts all other drivers in danger and is why signs are prohibiting commercial vehicles.
"We had 406 traffic stops alone just for commercial vehicles," said McElwain.
Park rangers issued more than 140 citations on those stops.
Mcelwain added commercial vehicles are also endangering people who may be walking or biking along the trace.
"The main big issue is poor planning of the driver's trip," McElwain.
Park rangers are urging commercial vehicle drivers to take routes that do not include the trace.
Driving the trace can earn you a trip to jail.
"It is a misdemeanor crime, so that can be fined up to 500 dollars and six months imprisonment," said McElwain.
U.S. Park Rangers are asking the community to call and report commercial vehicles they see on the Natchez trace.
However, they said don't call 911, instead call 1-800-300-park(7275)
