ELIZABETHTOWN, Ky. — A Kentucky State Police trooper rescued four people from an overturned vehicle that was beginning to catch fire Friday afternoon following a collision on Interstate 65 in Hardin County.

KSP Post 4 responded at approximately 2:10 p.m. to a two-vehicle collision near the 87-mile marker of southbound I-65. A caller reported that one vehicle had overturned with a family trapped inside and that the vehicle was smoking.

Trooper Blaine Miller was in the area responding to an unrelated incident and arrived at the scene almost immediately, according to KSP.

Miller found four people trapped inside the overturned vehicle, which was smoking and beginning to catch fire.

The trooper breached the vehicle’s front windshield, climbed inside and helped remove all four occupants to safety, KSP said.

The occupants were identified as Samantha Bloom, 28; Joshua Bloom, 22; Sarah Bloom, 26; and Savannah Bloom, 24, all of Louisville.

A preliminary investigation indicates a tractor-trailer operated by Steven Hawkins of Munfordville was traveling southbound when it merged from the middle lane into the right lane near the 87-mile marker.

According to KSP, the tractor-trailer forced a 2013 Honda CR-V, driven by Savannah Bloom, off the right shoulder.

The Honda then rolled several times before coming to rest on its side.

All four occupants of the Honda sustained minor injuries and were transported to Baptist Health Hardin in Elizabethtown. They were treated and released, according to KSP.

Hawkins was not injured and declined medical treatment.

KSP Post 4 was assisted at the scene by the Hardin County Sheriff's Office, Hardin County EMS, Glendale Fire Department, Central Hardin Fire Department and Elizabethtown Fire Department.

The crash remains under investigation.
