It only took four laps in the NASCAR Chicago Street Race for a big crash, with seven cars involved in a Michigan Avenue pileup.
The start of the Grant Park 165 was calm and collected, but things quickly turned sideways as the No. 77 car, driven by Carson Hocevar, slammed into the wall as it turned into Michigan Avenue, quickly causing a chain-reaction crash.
Hocevar started third in the race, with his car towed to the pit area.
In addition to Hocevar, Brad Keslowski, Daniel Suarez, Will Brown, Todd Gilliland, Riley Herbst and Austin Dillon were caught up in the wreck, which caused an early delay as cars were cleaned from the track.
A red flag was flown on the track during the delay.
