Tallahassee, Florida:
The Florida Highway Patrol is releasing a report on the fog- and smoke-shrouded Interstate 75 crash that killed 11 people in January.
The inspector general's report on whether state troopers erred when they reopened the highway shortly before the massive pileup is due out Thursday.
At least a dozen cars and pickup trucks, six semi-trailer trucks and a motorhome collided in north Florida near Gainesville. Some vehicles burst into flames, making it difficult to identify the victims.
The highway was blanketed with smoke from a wildfire as well as fog.
The report also may help officials decide whether to change protocols for determining when to shut down and reopen highways.
The Legislature, meanwhile, has appropriated money for visibility evaluation equipment and signage to warn travelers on all Florida interstates.
