Semi truck veered across three lanes of I-94 traffic in potential medical emergency crash that ejected driver

A truck driver is dead after a crash on Interstate 94 that sent him veering across three lanes of traffic and ended in an ejection. 

The accident happened on March 24th in Berrien County, Michigan on I-94 near the Indiana state line at 4:26 p.m.

According to 13 ABC, 45-year-old truck driver Jeffrey Oneal was heading eastbound on I-94 when nearby motorists noticed him struggling to maintain his lane. Oneal then suddenly veered left across three lanes of traffic and the median before traveling into the westbound lanes. Oneal then crashed into a second semi truck and was ejected from the truck cab. 

First responders attempted life saving measures on Oneal, but he succumbed to his injuries. The second truck driver, Pawel Dobrowolski, was unhurt in the accident. 

Witnesses say Oneal appeared to be in some sort of medical distress prior to the wreck. Authorities are still investigating the incident, and officials are waiting on an autopsy to determine if Oneal suffered a medical emergency. No further information has been released.
