Section 8: Safety Considerations
Car Safety Structures
- Aeroscreen: The titanium-framed ballistic screen protects the driver's head from debris and impacts while keeping the open-cockpit character of the car.
- Survival cell: The carbon-fiber monocoque, with front, rear, and side impact structures, is engineered to absorb crash energy and protect the driver.
- Restraints: The driver harness, fitted seat, and headrest work with the head-and-neck restraint to limit movement in an impact.
Circuit Safety
- SAFER barriers: Energy-absorbing barriers line oval walls and high-risk points on road and street courses to soften impacts.
- Run-off and barriers: Road courses use gravel traps and run-off; street courses use tire packs and reinforced walls where run-off is limited.
- Debris management: Full-course cautions are used to clear debris and recover stranded cars safely.
Safety and Medical Response
- The AMR INDYCAR Safety Team travels with the series and is stationed around every circuit for rapid response to incidents — extrication, fire response, and initial medical care.
- INDYCAR Medical provides on-site physicians and a medical center at each event; drivers involved in significant incidents are evaluated before being cleared.
- A concussion-evaluation and return-to-competition protocol governs when a driver may resume competition after a head impact.
Weather and Conditions
- On road and street courses, racing continues in the rain on wet-weather tires when conditions allow; the Race Director may red-flag for standing water or poor visibility.
- Oval racing is stopped for rain, because the cars cannot run safely on a wet oval; sessions are delayed or rescheduled.
- Lightning, extreme heat, and other hazards are monitored, and sessions are suspended when conditions are unsafe for competitors, crews, and spectators.
Driver and Crew Welfare
- Drivers must meet fitness standards appropriate to the physical demands of oval and road/street racing.
- Pit crew members are required to wear fire-resistant gear and helmets while working on pit lane.
- Mandatory orientation and refresher programs ensure drivers are prepared for the specific demands and speeds of each circuit type, especially superspeedways.
