The Florida Highway Patrol is monitoring parts of I-75 for smoke issues caused by a nearby brush fire.
Authorities are urging drivers to use caution when traveling near the 446 mile marker in Hamilton County. Visibility may deteriorate due to the smoke, especially during the night.
Drivers are encouraged to reduce their speed and use low-beam headlights.
The warning comes on the anniversary of the deadly I-75 25-car pileup between Ocala and Gainesville. That crash killed 11 when fog and smoke from a brush fire caused deadly conditions.
