Each Formula One car is required to carry the number published by the FIA at the start of each season. This number appears on the side and nose of the car and is at least 25 mm in height, so as to be clearly visible. Unlucky number 13 is excluded from the list

FIA-appointed race officials who are responsible for the reviewing of on-track events during Grand Prix weekends involving teams and drivers and, where necessary, assessing penalties

The weight of an F1 car in race trim, including the driver and full fuel tank

The time it takes a driver to react to the green starting light on the Christmas Tree, measured in thousandth of a second. The reaction-time counter begins when the last amber light flashes on the Tree, and stops when the vehicle clears the stage beam

A metal blade that extends the width of the rear deck lid on a stock car. It creates downforce on the back of the car, which gives the car more traction and better handling

Thirty minutes before the scheduled start of a Grand Prix, the cars leave the pits to cover a single reconnaissance lap. At the end of the lap, they are then aligned on the starting grid in qualifying order. Those drivers who wish to cover a second reconnaissance lap must travel down the pit lane at a greatly reduced speed, and may not in any circumstances drive through the Starting grid

A special piping device that was designed to refuel cars safely during pit stops. It is possible to deliver 60 litres of fuel in 5 seconds

A stop scheduled to regroup cars still in rally. No service is allowed

In a quest to maintain level performance field and keep cars safer. In some forms of motorsports, cars are required to have maximum air intake channel restrictor. Since engine power is dependent on amount of air, this is effective way to keep engine power in check

Race tracks with complex configurations of left and right-hand turns at varying angles. Tracks have a tendency of elevation changes as well. Example: Sears Point Raceway and Watkins Glen International

Section between two time controls that is not either stage, regrouping or service area

Roll bars are made of strong steel tubing with a minimum thickness and are part of the car's protective frame. The roll cage safeguards the driver and important components of the car from impact with other cars and walls or other barriers

Every F1 car is obliged to have two rollover structures (rollbars) that stand above a reference plane (higher than the driver's head). The first must be in front of the steering wheel, but no more than 25cm forward of the top of the steering wheel. The second must be behind the driver, and at least 94cm above the reference plane. Both rollover structures must be designed and fabricated in such a way that the driver and his steering wheel are at least 70mm below their highest points at all times

When a stock car gets sideways on the track, the flaps pop up and act much like the flaps on an airplane wing, slowing the car and helping prevent it from becoming airborne

A driver competing in their first year of the series

This annual award is given to the first-year driver whose combined average finishes are higher than any other first-year driver

A crew member changes the pressure on the rear springs to adjust the handling of the car. A wrench is inserted in a hole in the rear window of the car during a pit stop

Revolutions per minute, or rpm, is a measure of engine speed as determined by crankshaft spin

Influences the handling of the car. To increase tension, a piece of rubber is placed between the coils of a spring. To decrease tension the piece of rubber is taken out
