A 75-year-old woman from Tennessee became confused while driving in Spring Hill Wednesday morning and caused a wrong-way crash on U.S. 19, authorities say.

According to the Florida Highway Patrol, Martha B. Lester was driving a Mercury sedan north on U.S. 19 just before 6:30 a.m. when she attempted a left turn at Forest Oaks Boulevard.

Troopers said during the turn, she became disoriented and began driving northbound in the southbound lanes of U.S. 19.

Lester's vehicle collided with a southbound Chevrolet sedan, driven by Ann M. Morton, 42, of Spring Hill.

Both women suffered minor injuries. Lester was transported to Bayonet Point Hospital.

Portions of the southbound lanes of the highway were closed for more than an hour, troopers said.

The crash is under investigation.
