Learn the fundamentals of car racing.

Britannica describes automobile racing as a professional and amateur sport run on roads, tracks and closed circuits around the world, and lists Grand Prix, speedway, stock car, sports car, drag, midget car racing, karting and hill climbs among its forms. That variety is why newcomers find it confusing: the flags, the start procedure, the way a winner is decided and even the meaning of a white flag change from one organization to the next.

This section covers the basics. It explains how racing is organized, what the flags mean under three rule sets (the FIA's, SCCA's and NASCAR's), how a professional race weekend runs, the basic physics of grip, and the entry-level ways to drive on a track. The pages that touch safety state requirements as the organizers publish them, with the year of the source, and point you back to the current rules of the event you enter.

Four ideas to carry with you

Flags are not universal

Under FIA Appendix H (2026), a white flag warns of a much slower vehicle on track. SCCA shows it two stations before a slow or emergency vehicle. In NASCAR it means one lap to go. The event's supplementary regulations and briefing say which flags it uses, and those are what you follow. See flags.

Grip is shared

Wikipedia's article on the friction circle, citing vehicle dynamics textbooks, describes a tyre as having a limited total amount of horizontal force, which it shares between cornering and braking or accelerating. How much it has depends partly on the load pressing it down, so weight moving around the car changes each tyre's share. See how grip works.

Entry-level events are not races

SCCA says plainly that its track days are not races, and SCCA Time Trials says time trials are not wheel-to-wheel competition. Autocross is run against the clock on a course laid out with cones. Wheel-to-wheel racing needs a licence, which comes after schooling. See getting started.

Instruction is built in

NASA requires an instructor for its first HPDE group, and the 2026 SCCA Track Day Rules give novices classroom sessions and an observing coach. SCCA requires a Drivers' School or an accredited school before a road racing licence. See track days and licences and schools.

Where to go next

Once these basics are familiar, the technique section explains driving principles as schools and coaches teach them, starting with the racing line. The disciplines section describes each type of racing in more depth, the equipment section covers helmets and safety gear, and the events section covers the governing bodies and major series. Unfamiliar words are defined in the glossary.
