Timmy Hill

Hill began his racing career in 2005 by karting at the age of 12. During his first season, he recorded more than 80 victories, as well as winning two World Karting Association championships, two King George Speedway championships, the Concord Speedway Winter Championship. He also finished third in the World Karting Association National Championship. Once the 2005 season concluded, he began racing Bandoleros. In 2006, he scored ten wins. One year later, Hill began racing Legend cars and in the Allison Legacy Series. During the season, Hill failed to win a race. However, in 2008, he managed to win four Legend car races and two in the Allison Legacy Series. In the Allison Legacy Series, he finished fifth in the point standings.

During the 2009 season, Hill won ten Allison Legacy Series races and finished first in the point standings. In Legend cars, he won two races in the Winter Heat Series and won the Summer Shootout at Charlotte Motor Speedway. In the following year, he began racing in the ARCA Racing Series and the K&N Pro Series East while continuing racing Legend cars. In Legend cars, he won seven races, while recording two top-ten finishes in the K&N Pro Series and one in the ARCA Racing Series.

In 2011, Hill began racing in the NASCAR Nationwide Series at Phoenix International Raceway, having been too young to compete in the season opener at Daytona International Speedway, not yet having passed his eighteenth birthday. During the season, he had a best finish of 11th at Road America and finished 17th in the point standings, winning the Rookie of the Year award. After a close battle with Blake Koch and Ryan Truex, Hill edged Koch by a single point at Homestead-Miami Speedway to take Rookie of the Year honors. He competed in 33 of the 34 events scheduled for the season, and scored top-20 finishes in five.

For 2013, Hill returned to the No. 32 team for a part-time schedule of 19 races with OXY Water and U. S. Chrome sponsorship, and declared for Sprint Cup Rookie of the Year honors (again) He would finish third in the Rookie of the Year standings, behind full-time drivers Ricky Stenhouse Jr. and Danica Patrick.

Hill would drive the No. 33 Chevy part-time for Circle Sport in 2014 after starting the year without a ride after he was replaced in the No. 32 by Travis Kvapil that year. He was involved in a controversy at Bristol when, while running in last place, Hill failed to slow his car under caution and crashed into the rear of the stopped car of Matt Kenseth, who was running in second place at the time. Hill would later state that his spotter did not tell him the caution flag was out, and he did not see the safety lights around the track turn on. NASCAR on Fox analyst Darrell Waltrip famously called out Hill for a "rookie mistake" at the moment of the incident, though he recanted his harsh tone late in the broadcast. He also practiced and qualified Landon Cassill's No. 40 Circle Sport car at Sonoma when Cassill was in Road America for the Nationwide race that day. Hill would also drive in two races each for the Identity Ventures Racing and Xxxtreme Motorsports teams. IVR was a team with a limited alliance with Michael Waltrip Racing. At Pocono in June, he drove the No. 66 Toyota and would finish 36th. At New Hampshire in July, he drove the team's other car, the No. 87, to a 41st-place finish. In his two races in Xxxtreme's No. 44, Hill finished 43rd (at Dover) and 42nd (at Martinsville in October).

In 2015, Hill returned to Identity Ventures, now renamed Premium Motorsports, where he would drive part-time in both the No. 62 in the Cup Series and the No. 94 in the Truck Series and later the No. 98 in Cup as well after they bought the Phil Parsons Racing team. He made his first Xfinity Series (previously Nationwide) start of the season at Texas in the No. 13 for Carl Long's MBM Motorsports team. Hill would make 6 more starts with Long, but his best finish would come in his first of three starts with JGL Racing, where he finished 11th in the No. 26 Toyota at Daytona in July. In the Truck Series, Hill would run a total of 12 races for Premium Motorsports in the No. 49 Chevy Silverado. Nine races resulted in top 20 finishes with a best finish of 15th at Dover and Kentucky. Hill's 2015 Cup debut came in the July race at Loudon. His best finish came at Pocono, where he finished 36th. Hill would go on to run 11 more races for Premium Motorsports.

Hill's 2016 season started in the season-opening Truck race at Daytona, driving the No. 49 for Premium. After running up front in the top 10 for most of the race, Hill was spun out while running in the top 5 on the last lap, relegating him to 14th. As of September, Hill had run 11 Xfinity races with a best finish of 22nd at Loudon in the No. 13 for MBM. Hill announced in August that he would be running the remainder of the 2016 Xfinity Series season for MBM.

In 2017, Hill returned to Rick Ware Racing to drive the No. 51 in the Cup Series starting at the Daytona 500, but failed to qualify. Starting at Dover, Hill would drive for MBM Motorsports in the No. 66 as well at Kentucky and possibly more races. At the Brickyard 400, Hill avoided numerous incidents to record his and MBM's best finish, a 14th.

In 2018, Hill continued to drive for MBM at multiple levels, scoring his and MBM's first top ten, a seventh at Daytona in July. He continued with MBM in 2019, earning a seventh-place finish at Bristol in August in a car that was fielded in collaboration with Hattori Racing Enterprises.

Hill became married in January 2018. His younger brother Tyler races part-time in the ARCA Racing Series, Xfinity, and Truck Series.

During the 2019 NASCAR Gander Outdoors Truck Series season, Hill formed Hill Motorsports, fielding the No. 56 Silverado part-time for himself and brother Tyler Hill; the number was used by their father Jerry during his career. The team used trucks acquired from MDM Motorsports over the 2018–2019 offseason.

The team debuted in the 2019 TruNorth Global 250 at Martinsville Speedway. In the second Martinsville race of the year, the NASCAR Hall of Fame 200, Hill escaped multiple wrecks to finish fifth.
