at Charlotte Motor Speedway, and was voted the most popular driver on the circuit. Winston Cup Series Moroso made his debut in Winston Cup in 1988 at Charlotte in the No. 47 Peak Antifreeze Chevrolet for Hendrick Motorsports, finishing 14th. He would race one more time in 1988 and ran two races in 1989 as a warm up for the following season. Moroso declared he was running for Rookie of the Year in the 1990 season, driving the No. 20 Crown Central Petroleum Oldsmobile for his father. The highlight of the season was a ninth-place finish in the Pepsi Firecracker 400 at Daytona. Other than that, Moroso posted no wins, no top 5's, and only 1 top 10 and DNF'd in 15 races. Death On September 30, 1990, four days after his 22nd birthday, Moroso was killed in an automobile crash on North Carolina Highway 150 near Mooresville, North Carolina, only hours after finishing 21st in the Holly Farms 400 at North Wilkesboro Speedway. Traveling at an estimated , Moroso lost control of his vehicle in a curve with a posted speed limit, skidding over 200 feet before being struck in the driver's side door by an oncoming car in the opposite lane. The resulting collision killed both Moroso and Tammy Williams, a 27-year-old nursing assistant, wife and mother who was driving in the opposite lane. The passenger in Moroso's vehicle, girlfriend Debbie Bryant, as well as a passenger in Williams' vehicle both survived with injuries. Investigations revealed that he had been driving under the influence of alcohol. Moroso had been seen drinking several beers at a Cornelius, North Carolina, lounge prior to the crash, and his blood alcohol level was found to be 0.22, over twice the then legal level of 0.10. He also had been convicted of speeding four times between 1987 and 1989, and had been involved in two prior highway crashes which included a rollover. Judges could have revoked his license at least twice but the charges were reduced. Moroso earned enough points after completing just 25 of 29 races that he was awarded the Raybestos NASCAR Rookie of the Year Award in 1990, the only driver to ever receive the award posthumously.
