A truck driver and their passenger escaped unharmed after a drowsy driving accident early Wednesday morning. 

The accident occurred on August 19th at approximately 1:38 a.m. in Castaic, California. 

According to On Scene News, the semi truck was traveling along The Old Lake and Lake Hughes Roads near Interstate 5 when the driver reportedly fell asleep, causing the rig to overturn. 

When emergency crews arrived, they discovered a small patch of grass had caught fire as a result of the crash, and quickly distinguished it. 

Luckily, both the truck driver and their passenger were able to escape the overturned rig on their own, apparently uninjured. 

The truck was hauling 40,000 pounds of dog food at the time of the crash.
