Hairpin
Slow speed, 180 degree turn. Executed with help of handbrake.
HANS
Head And Neck Support, a safety device that rests on user's shoulders and is attached to helmet via straps. It's intention is to reduce whip-lash injuries in accidents by restraining the head movement.
Helmet
Besides fire-resistant overalls, helmet is primary safety device worn by the drivers. There are two distinct types of helmets, open face and full face (also called integral). An intermediate model has been introduced by italian manufacturer Stilo, incorporating fully integral intercom with microphone boom coupling as protection.
Homologation
A procedure in which FIA confirms that a car (or other piece of equipment, FIA also approves accessories like helmets) meets technical requirements of the rules. Laid in simple terms, homologation starts out with manufacturing stating that they have this car, contructed out of these parts and coming up to these specifications. Forms they have filled out are then checked against the actual car by FIA to certify that statements are correct and comply with the technical regulations.
If homologation is passed, the car is thereafter deemed homologated and can be used in rallies. There are modifications that do not need a new homologation but in a case of more extensive modifications, manufacturers create a new evolution of the car and homologate it. Manufacturer can make only one new homologation of the same car annually. See also scrutineering.
