NASCAR issued penalties to at least 13 drivers at Rockingham Speedway ahead of Truck Series action this weekend.

While it’s a rare off weekend for the Cup stars, the O’Reilly Auto Parts Series and Truck Series are in action in North Carolina, with a jam-packed schedule across Friday and Saturday.

Truck Series action is being squeezed into one day, with practice, qualifying and race action all taking place on April 3.

However, as is the case at every event on the NASCAR calendar, the trucks had to go through technical inspection before hitting the track, and several cars have been punished after being scrutinized.

13 drivers in total were held back for 10 minutes at the start of Truck Series practice on Friday.

While often punishments are only handed out for more than one technical inspection failure, FOX Sports’ Bob Pockrass has revealed that the drivers in question have been penalized for failing inspection on their first attempt for two consecutive weeks.

Those drivers whose trucks failed inspection on the first time through and were held for 10 minutes at the start of practice were:

Truck No. 10 — Corey LaJoie — Kaulig Racing
Truck No. 12 — Brenden Queen — Kaulig Racing
Truck No. 16 — Justin Haley — Kaulig Racing
Truck No. 18 — Tyler Ankrum — McAnally Hilgemann Racing
Truck No. 22 — Clayton Green — Team Reaume
Truck No. 33 — Frankie Muniz — Team Reaume
Truck No. 34 — Layne Riggs — Front Row Motorsports
Truck No. 56 — Timmy Hill — Hill Motorsports
Truck No. 81 — Kris Wright — McAnally Hilgemann Racing
Truck No. 90 — Justin S Carroll — Terry Carroll Motorsports
Truck No. 91 — Christian Eckes — McAnally Hilgemann Racing
Truck No. 93 — Caleb Costner — Costner Motorsports
Truck No. 99 — Ben Rhodes — ThorSport Racing

On top of this, the No. 69 truck driven by Jonathan Shafer this weekend failed inspection multiple times on Thursday.

Last time out at Darlington, four trucks failed tech twice ahead of the event, resulting in the ejection of their respective truck chiefs and the loss of pit stall selection for this weekend at Rockingham.

It is unclear what Shafer and his team will be hit with as a result of their failures, but he will be a DNQ for Friday’s race, regardless, after a crash and heavy damage to his truck in practice.

What is NASCAR tech?

Every weekend, no matter the race, track, or event, NASCAR requires all teams to pass inspection before hitting the circuit.

If a team fails tech on the first instance, it must fix the issue and repeat the process all over again until it passes.

According to NASCAR, the point of inspections is to level the sport’s playing field as much as possible.

The website also outlines the five stations of a standard inspection, which are as follows:

Station 1: Car is elevated to visually inspect the nose, under the body and inside.

Stations 2-3: Body is visually inspected using a handheld template to ensure the body conforms to regulations.

Station 4: Optical scanning is used to inspect the chassis and body of car.

Station 5: Holding blocks are removed and final safety inspection is done.
