A 23-year-old motorist died Wednesday in a head-on collision with a Mack truck on La. 662 in Assumption Parish.

Tasha Massoletti, of Morgan City, was driving northbound on La. 662 in a 2003 Ford F-150 about 9:30 a.m., when her truck crossed the center line and struck a Mack truck heading in the opposite direction, State Police Troop C spokesman Evan Harrell said.

Massoletti, who had been wearing a seat belt, was pronounced dead at the scene by the Assumption Parish Coroner’s Office, Harrell said.

The driver of the Mack truck, Carlos Gonzalez, 43, of Welsh, also was wearing a seat belt but was not injured. A breath test showed he had not been drinking.

It is not yet clear whether Massoletti was impaired, as toxicology results are pending, Harrell said.

The collision remains under investigation.
