Slower car, often not on the lead lap.

This straight section of track is usally located on the opposite side of the start/finish line.

A flame retardant, mask-like head covering worn by the drivers, complete with openings for the nose, eyes and mouth.

Open-wheel cars must be precisely balanced to make the handling accurate and predictable. Can be affected by humidity and temperature of the track.

Oval tracks are slanted away from the outside retaining wall to help the cars stay on the racing surface. Banking typically is several degrees more in the corners than on the straightaways.

When two cars race each other for the same place - whether first place or last place.

Shown in conjunction with a white number to a driver for dangerous or non-sporting on-track conduct. The offending driver must stop at his team's pit within one lap and consult the Clerk of the Course. A black and white diagonal flag is a "once-only" warning to a driver for non-sporting on-track behaviour. A black flag with red spot shown in conjunction with a competitor's number indicates the driver's car has a mechanical problem and he is must stop at his pit.

Tires have optimal working temperature and if this temperature is exceeded significantly, tires can blister. When this happens, rubber loses its internal construction and begins to fall apart.

A driver will position his car where he thinks another driver is going to try to pass him in order to make space unavailable.

At all times: A stationary blue flag is shown to a driver when exiting the pits to indicate other cars are approaching on the track at racing speed. During practice: Stationary - a faster car is behind. Give way. Waved - A faster car behind is about to overtake. Give way urgently. During Race: Stationary - A car behind is about to pass. Let it pass. Waved - Let the car behind through immediately or risk being penalised.

Turbo-charger forces air into combustion chamber with pressure that is much higher than atmospheric pressure. On most road-going cars equipped with turbo, this boost is limited under one bar but race cars go well beyond that.

A type of an air happer that is especially made to direct air onto the brakes to cool them down. These can very from race to race, following the needs of brake cooling, as one circuit/track may demand more brake performance than another.

Used only in handicap racing, the term breakout refers to a contestant running more quickly than he or she "dialed-in" his or her vehicle (i.e. predicted how quickly it would run). Unless his or her opponent commits a more serious infringement (e.g. runs a red light, crosses the centreline, or fails a post-race inspection), the driver who breaks out, loses. If both drivers break out, the one who runs closest to his or her dial-in is the winner.

Spinning the rear tires in water prior to a run, to heat and clean them for better traction. A burnout precedes every run.
