NASCAR released a major revision to its rulebook on Friday, officially removing all references to “playoffs” and “playoff points” to align with the return of the Chase for the Championship structure this season. This update formalizes the new rules while also incorporating related changes and various other adjustments reviewed during the offseason.
One key change involves how penalties for driver suspensions affect their championship chances. Previously, suspensions would cost drivers all playoff points, effectively ending their title run early, as seen with Austin Hill last season. Under the new rules, a suspended driver simply cannot earn points in the race they miss, but this no longer automatically eliminates them from contention. If NASCAR grants a waiver for reasons other than a NASCAR-initiated absence, the driver will start the final championship event with 2,000 points and no option to appeal NASCAR’s decision. A spokesperson clarified that suspended drivers now retain their regular season standings for postseason reseeding rather than dropping to 2,000 points.
NASCAR has also closed a loophole related to the Fastest Lap bonus point. Last year, drivers like Kyle Larson exploited damaged cars to set the fastest lap and earn an extra point, disadvantaging those still racing competitively. Now, any team whose vehicle is subject to the Damaged Vehicle Policy will be ineligible to receive Fastest Lap points for that event.
In addition, NASCAR plans to add grid spots 37 through 40 for new OEM vehicles during the first three races of 2026 under the Kaulig Racing banner with RAM trucks, allowing them to earn owner points; failing to win early on locks them in for the full season starting at race four.
Experienced Cup Series drivers can now enter up to 10 events in the O’Reilly Auto Parts Series and eight in the Craftsman Truck Series—an increase from five races in 2025. However, Cup drivers who earn points in the Cup Series cannot compete in the championship stages of the lower-tier divisions.
Age restrictions have been eased for the O’Reilly Truck Series, lowering the minimum age to 17 for tracks 1.25 miles or shorter and for road courses, making this consistent with the Truck Series limits.
Regarding race conduct, updated penalties for loose lug nuts differ between the Truck and O’Reilly Series, with escalating fines, crew suspensions, and potential disqualification for repeated infractions.
Weekly rankings and eligibility indicators, as well as stage lengths and pit road speeds, have been clarified with detailed visuals provided for the Cup, O’Reilly, and Truck Series.
Several tire tests are scheduled for 2026 at Las Vegas (March 16), Chicagoland (April 21-22), Iowa (May 12-13), and Indianapolis (June 2-3). Although tissue testing was recently conducted in North Wilkesboro, no further tests are currently planned.
For drivers returning from injuries, strict testing protocols have been established requiring medical documentation, controlled testing environments without spectators, and limitations on data and equipment use to ensure safety and fairness.
NASCAR also updated its prohibited substances list to include a wide range of stimulants, narcotics, ephedrine-based products, benzodiazepines, barbiturates, performance-enhancing drugs such as anabolic steroids and growth hormones, muscle relaxants, sleep aids, beta blockers, hormones, and metabolic regulators. The policy prohibits use of any substances not approved by health authorities or prescribed for legitimate medical reasons.
Finally, detailed stage lengths, pit road speed limits, and related race-specific rules have been outlined for each series to ensure consistency and adherence to safety standards.
Fan Take: These rulebook updates signal NASCAR’s commitment to refining the sport’s competitive structure while promoting fairness and safety. For fans, the return of the Chase format and adjusted suspension rules could lead to more exciting, unpredictable championships and keep more drivers in contention longer, making the 2026 season one to watch closely.
