Jennifer Jo Cobb

In 2018, Cobb joined Racing Total for her NASCAR Whelen Euro Series debut at Circuit Ricardo Tormo in Valencia.

On May 29, 2015, Cobb angrily approached the race car driven by Tyler Reddick on foot after apparently by being spun out by Reddick's truck at the Lucas Oil 200. It was expected that Cobb would be the first driver penalized under the new NASCAR rule instituted after Kevin Ward Jr. died in a similar incident. She wound up receiving a $5,000 fine from the officials.

During practice for the 2015 Chevrolet Silverado 250 at Canadian Tire Motorsport Park, Cobb crashed and was subsequently caught on camera removing a cell phone from her truck. Cobb was given a P3 penalty by NASCAR for having a non-engine electronic component in her truck. As a result, Cobb was fined $5,000, plus an additional $2,500 for an infraction occurring while still on probation for the incident with Tyler Reddick where she left her truck following a crash. Cobb was the first driver penalized by NASCAR under the no cell phone rule since it was implemented following the 2012 Daytona 500.

For the 2014 season, Cobb again ran in the Truck Series in her own No. 10 Chevrolet Silverado. The team began the season with a 21st-place finish in the NextEra Energy Resources 250. At the SFP 250 Cobb raced to 13th place which earned her highest finish of the season, she then had another strong run at the North Carolina Education Lottery 200 (Charlotte) finishing 16th. However, since that 16th-place finish, the team has seen a decline in performance as they have only managed to eclipse a best of 20th on three different occasions (Dover, Kentucky, and Michigan).

Cobb also ran one race in the No. 87 car for Rick Ware Racing at the Kansas Lottery 300 finishing 24th, which was her first Nationwide Series start of 2014.

On May 15, 2013, her team's hauler (which was formerly owned by Circle Bar and purchased by Cobb when she bought the No. 10 truck from them) and some other various equipment was stolen by fellow driver and team owner Mike Harmon, who Cobb previously was a driver for part-time in the Xfinity Series in 2007 and 2009. Although Harmon stated that he was innocent, he was arrested and charged with stealing this equipment since they belonged to Cobb. Harmon stole those items in association with his sister and Dave Novak, a former partner in the ownership of Cobb's team who later moved over to Harmon's team. On May 28, officials from the Rowan County Sheriff's Office seized five Camping World Truck Series trucks and two Nationwide Series cars, which were stated as belonging to Cobb, from Harmon's garage.

In 2012 Cobb ran the entire Camping World Truck Series schedule in the No. 10, along with selected Nationwide Series races in the No. 13. She returned to the Camping World Truck Series for 2013.

Cobb is married to NASCAR crew chief and former driver Eddie Troconis, who was Cobb's crew chief in the Xfinity Series in 2012. They married in 2015. Troconis currently crew chiefs for AM Racing's No. 22 truck driven by Austin Wayne Self in the Truck Series, which Cobb also currently competes in with her own team.

For 2011, Cobb continued racing her own No. 10 truck full-time in the Camping World Truck Series, and also drove the first 5 races in the Nationwide Series in the No. 79 for 2nd Chance Motorsports. On the truck side, Cobb became the highest finishing female in Truck Series history by finishing 6th at the 2011 NextEra Energy Resources 250. She would hold this record for nine years, when Natalie Decker broke the record with a fifth-place finish, also at the season-opening Daytona race, in 2020. Cobb later announced that she would run the full season with 2nd Chance Motorsports in their No. 79 Ford and run for Rookie of the Year. Cobb later gave her truck's owners points to Chase Mattioli and his team while she also started her own driver development program with Cody Cambensy planning to drive in the Truck Series in 2011. She later left 2nd Chance Motorsports after a dispute with owner Rick Russell over whether to start and park after losing their second car at Las Vegas, where she confirmed she is not a start and park driver. Rick Ware Racing later gave her a ride in the No. 41.

In early 2011, Cobb for her own team called Jennifer Jo Cobb Racing and partnered with U.S. Army Family and MWR Command to launch Driven 2 Honor, a promotion honoring women in the U.S. Military. Jennifer hosted 2 female service members and their guests at the first 5 Nationwide races of the 2011 NASCAR season.

In 2010, Cobb announced that she would run full-time in the truck series, after purchasing the assets of the No. 10 truck team from Rick Crawford, whose Circle Bar Racing downsized from a two-truck operation to one — Crawford's own No. 14 (which would also close down early in the season). Cobb kept the same truck number and owner points from Circle Bar. Also that year, Cobb became the highest female points finisher in history in any of the three major NASCAR Series to that time, achieving 17th place.

On July 19, 2008, she competed in the Camping World Truck Series event at the Built Ford Tough 225. She started in 35th and finished 26 driving the No. 74 Dodge for The Annexus Group completing 144 laps. On April 27, 2009 she competed at the O'Reilly Auto Parts 250 driving the No. 73 Dodge for Derrike Cope Inc. She started 34th and completed 72 laps before experiencing engine trouble, finishing 26th out of 35 drivers winning a purse of $10,680.

In 2006, Cobb created a line of clothing for female race fans called Driver Boutique. Proceeds from the sales of this line go towards her racing efforts, and she has attempted to qualify for various Busch and ARCA races in 2007 with the Driver Boutique sponsorship.

In 2004, Cobb made her NASCAR debut in the Busch Series at Homestead-Miami Speedway. She drove the No. 50 Vassarette Chevrolet for Keith Coleman Racing and finished 43rd due to a crash on lap 2.

She started racing in 1991 at Lakeside Speedway. Her father, Joe Cobb, races at Lakeside Speedway in the modified division. Since 2002, she has made 9 starts in the ARCA Racing Series, including 3 top-10s in 3 starts in 2004 while driving for Keith Murt.
