NASCAR : Chaos Erupts at Daytona 500 as 20 Cars Collide in Dramatic Turn 4 Crash

A massive 20-car wreck, dubbed "The Big One," erupts on Lap 124 of the Daytona 500. Denny Hamlin attempts to pass leader Justin Allgaier in Turn 4, sparking chaos. Allgaier, in the No. 40 JR Motorsports Chevrolet, blocks Hamlin, who receives a bump from Ryan Blaney in the No. 12 Team Penske Ford. The collision sends Allgaier and Hamlin spinning, collecting numerous drivers in the process. Bubba Wallace navigates the disaster, seizing the lead unscathed. The wreck halts the race, resulting in a caution that lasts through Stage 2, handing Wallace the stage victory. Allgaier, Alex Bowman, and Todd Gilliland exit the race due to damage but are released from the infield care center shortly after. Hamlin's car remains intact but suffers radio issues. The green flag waves again on Lap 136 as the race resumes.
