Section 8: Safety Considerations
8.1 Driver Safety Equipment — Mandatory Requirements
All NASCAR Cup Series drivers must wear the following safety equipment during competition and on-track activity:
- Helmet: A full-face helmet meeting the current Snell SA or SFI 31.1A/2020 (or higher) standard is mandatory. Open-face helmets are not permitted. Helmet certification labels must be visible and unaltered.
- Head and Neck Restraint (HANS Device): A HANS (Head and Neck Support) device or equivalent SFI 38.1-certified head and neck restraint is mandatory for all drivers. The device must be properly fitted and attached to the helmet via SFI-rated tethers. This requirement has been in effect since 2001 and is credited with substantially reducing the risk of basilar skull fractures.
- Fire Suit: A one- or two-piece SFI 3.2A/5 (or higher) rated fire-resistant driving suit is required. Fire suits must cover the driver's entire body except for hands, feet, and face. Suits must be in good condition with no tears, burns, or damage that compromises fire protection.
- Fire-Resistant Gloves: SFI 3.3/5 (or higher) rated fire-resistant driving gloves are required.
- Fire-Resistant Shoes and Socks: Fire-resistant driving shoes (SFI 3.3/5 or higher) and fire-resistant socks are required.
- Fire-Resistant Underwear: Nomex or equivalent fire-resistant long underwear (top and bottom) is mandatory to be worn under the fire suit.
- Window Net: A properly mounted and latched window net is required on the driver's side window. The window net must be in good condition and must be released quickly in the event of an emergency (quick-release mechanism required).
8.2 Car Safety Systems
The Next Gen car incorporates several mandatory safety systems:
- Roll Cage: A multi-point chromoly steel roll cage is mandatory, conforming to NASCAR's structural specifications. The roll cage includes a primary hoop, front hoop, roof halo bar, door bars (minimum six per side), and rocker panel protection bars.
- Fuel Cell: A safety fuel cell (bladder-type, SFI 28.1 or FT3/FT3.5 equivalent) is mandatory in place of a conventional fuel tank. The fuel cell is contained in a steel box mounted behind the rear axle.
- Fire Suppression System: An onboard fire suppression system (activating agent directed at the engine compartment, fuel cell area, and driver compartment) is mandatory. The system must be activated by a pull cable or button accessible to the driver and to safety personnel outside the car.
- Roof Flaps: Two aerodynamic roof flaps are mandatory on all NASCAR Cup Series cars. The flaps automatically deploy when airflow reverses over the roof (as in a spin), preventing the car from becoming airborne.
- Seat and Harness: A NASCAR-approved containment seat (custom-fitted, carbon fiber or aluminum with side-head containment wings) is required. The six-point harness (or NASCAR-approved equivalent) must be SFI 16.1-rated and no more than two years old.
- Kill Switch: An electrical master kill switch must be located on the dashboard and accessible to safety personnel through the driver's window. The kill switch must cut all electrical power and fuel flow.
- Tear-Off Panels: Windshield tear-off panels (multiple layers) are permitted and commonly used to maintain driver visibility during the race.
8.3 Track Safety Infrastructure
NASCAR works with track operators to ensure safety infrastructure meets required standards:
- SAFER Barriers (Steel and Foam Energy Reduction): SAFER barriers (also known as "soft walls") are required along the perimeter walls of all NASCAR Cup Series tracks. These barriers consist of steel tubing backed by foam blocks that absorb impact energy, significantly reducing the deceleration forces transmitted to the car and driver during wall impacts.
- CATCH Fence: Catch fencing is required around the perimeter of all NASCAR Cup Series tracks adjacent to spectator areas. The fencing is designed to retain debris and car components within the racing surface area in the event of a crash.
- Infield Care Center: A fully equipped medical care center (NASCAR Infield Care Center) staffed by NASCAR-contracted medical personnel must be present at all Cup Series events. The facility includes trauma care capabilities and is staffed throughout all on-track sessions.
- Safety Vehicles: Multiple Safety and Rescue Team vehicles, including fire suppression units, advanced life support units, and extrication-capable response vehicles, must be stationed on the infield at all times during on-track sessions.
8.4 Caution and Red Flag Procedures for Safety
NASCAR Race Control will immediately display the yellow caution flag or the red flag in response to any on-track incident presenting a safety hazard. The red flag requires all cars to immediately reduce speed and stop at a designated location on the racing surface (typically in front of the pit lane entrance) until NASCAR Race Control deems it safe to resume activity. Under a red flag, crew members may not work on cars unless specifically authorized by NASCAR for safety-related repairs (such as extinguishing a fire or clearing a safety concern). No car may pit during a red flag period without NASCAR authorization.
8.5 Pre-Event Safety Inspections
All safety equipment worn by the driver (helmet, HANS device, fire suit, gloves, shoes) is subject to inspection by NASCAR Technical Officials. Equipment that does not meet current NASCAR certification standards or that is found to be in a damaged or compromised condition may be rejected, requiring replacement before the driver is permitted to participate in on-track activity. Safety equipment certifications (Snell, SFI) have defined expiration periods; expired certifications are not accepted.
8.6 Post-Crash Medical Protocols
Following any significant on-track incident, NASCAR Safety Team personnel respond immediately. The driver may not exit the car until cleared by the Safety Team unless there is an immediate life-threatening hazard such as fire. The NASCAR Medical Director has authority to remove any driver from competition and require medical evaluation at any time. NASCAR employs a standardized concussion assessment protocol; any driver suspected of sustaining a concussion must be evaluated by NASCAR medical personnel and must receive clearance from the NASCAR Medical Director before returning to competition.
