Oval racing has always been a dangerous endeavour. All it takes is for one small incident to trigger a series of events and that's exactly what happened at the Daytona 300.
With just 16 laps to go, Ty Dillion tries to make a move on fellow competitor Daniel Hemric, unfortunately for Dillion, he couldn't execute his pass, and the driver of the 54 car was spun around causing a massive multi-car collision forcing a safety car period.
You can watch the crash below.
