Dale Earnhardt Sr. is survived by his wife Teresa Earnhardt and four children: Kerry Earnhardt, Kelley Earnhardt Miller, Dale Earnhardt Jr. and Taylor Nicole Earnhardt. The 2025 Daytona 500 will take place at 2:30 p.m. on Sunday, Feb. 16 at the Daytona International Speedway.

NASCAR icon Dale Earnhardt Jr. and JR Motorsports are set to make their highly anticipated Daytona 500 debut with Justin Allgaier behind the wheel of the No. 40 car, sponsored by Grammy-winner Chris Stapleton’s Traveller Whiskey brand.

Justin Allgaier will attempt to qualify for the 2025 Daytona 500 driving the No. 40 Chevrolet Camaro owned by Dale Earnhardt Jr. Greg Ives — Earnhardt Jr.'s crew chief in the Cup Series from 2015 to 2017 — will serve as the crew chief for the team.
