LaJoie, who had been named to the 2012 NASCAR Next class of up-and-coming drivers, entered the 2013 season with only a limited schedule planned, including selected NASCAR Nationwide Series races for Tommy Baldwin Racing, however in June it was announced that he had signed with Richard Petty Motorsports as a development driver, with plans to run in the Nationwide Series later that year. In addition, LaJoie ran a limited schedule in the ARCA Racing Series in the second half of 2013, winning his first start of the year, and second career start, at Chicagoland Speedway in July, and then in his next race at Pocono Raceway in August.
In November 2013, it was announced that LaJoie would make his NASCAR Nationwide Series debut at Homestead-Miami Speedway that month, driving the No. 9 Ford for Richard Petty Motorsports. He was involved in an accident during the race and finished 34th.
In June 2014, LaJoie joined Biagi-DenBeste Racing to drive five races, starting at Kentucky. LaJoie struggled in these races, crashing in three of them. In September 2014, LaJoie made his Sprint Cup Series debut in the Sylvania 300 at Loudon, racing for Randy Humphrey Racing.

In 2017, LaJoie returned to the Cup Series and signed with BK Racing, driving the No. 83 Camry part-time. LaJoie made the Daytona 500 controversially, as he got into the left rear of Reed Sorenson about halfway through the first Can-Am Duel, which resulted in Sorenson hitting the inside wall and retiring from the race. Many were led to believe that LaJoie wrecked Sorenson on purpose to get into the 500, although LaJoie denied doing so. LaJoie initially competed for points in the Cup series with BK Racing but switched to Xfinity at the last race.
In 2018, LaJoie moved from BK Racing to TriStar Motorsports for a part-time schedule, splitting the No. 72 with Cole Whitt.

He made his second start for the team at ISM Raceway in March, once again blowing an engine early in the race. In the Coca-Cola 600, LaJoie went as high as eighth but finished 26th. At year’s end, TriStar shut down, throwing LaJoie out of his part-time ride.

LaJoie joined Go Fas Racing's No. 32 Ford in 2019. For the 2019 Daytona 500, Go Fas Racing made headlines by placing a picture of LaJoie's face on the No. 32 car as part of Old Spice's sponsorship. LaJoie finished 18th after blowing a right-front tire just 20 laps into the race. He scored two top tens during the year with a sixth at Daytona's Coke Zero Sugar 400 and seventh at Talladega's 1000Bulbs.com 500.

On August 21, LaJoie announced that he will part ways with Go Fas Racing at the end of the 2020 season.
LaJoie racing at Daytona International Speedway in 2021
LaJoie moved to Spire Motorsports' No. 7 on a multi-year agreement beginning in 2021.
Since 2020, LaJoie has been represented by Athelo Group, a sports agency based out of Stamford, Connecticut.
After a tweet sent on October 15, 2013 with content deemed racially stereotypical, NASCAR put LaJoie on indefinite probation and required him to go through sensitivity training.
Trying to make the 2017 Daytona 500 as an Open team with BK Racing (no starting spot guaranteed), LaJoie was turning his first laps at Daytona International Speedway during the Can-Am Duels due to practice being rained out. Trailing Reed Sorenson, the only other Open driver, with under fifteen laps to go, LaJoie spun out Sorenson in the tri-oval, ensuring himself a spot in the 500 and making Paul Menard start at the back of the field as Menard was also involved in the crash and had to start in a backup car. After the race, LaJoie said that "I do feel bad" and that "if that was my mom, I'd probably spin her out to make the Daytona 500 too." Sorenson was incensed after the incident, calling the crash "moronic" and "pretty crappy" while saying that LaJoie could have hurt somebody with reckless driving.
LaJoie is a Christian. His father, Randy LaJoie, is a two-time NASCAR Busch Series champion, winning the series title in 1996 and 1997.
LaJoie was a host of Motor Racing Network's Sunday Money podcast alongside Daryl Motte and MRN's Lauren Fox, talking about racing and current events; LaJoie and Fox were classmates in high school. In 2021, he began hosting his own podcast Stacking Pennies on NASCAR.com. (Courtesy Wikipedia)
