Additional safety devices such as jack stands are required to ensure safety in the event of jack failure. Disregard of, or failure to observe, this rule is grounds for immediate disqualification. LICENSE: Each driver of a vehicle entered in any event conducted at an IHRA sanctioned facility must have a valid State driver’s license beyond a learners permit and a Competition License if mandated by class requirements (except Junior Dragster). This license is subject to inspection at any time. All drivers running 0-9.99 ¼ mile or 0 to 6.39 1/8th mile must obtain an IHRA or accepted competition license. All drivers running 0-9.99 (6.49 1/8th mile) who have not previously held a Competition License will be given a special cockpit orientation (blindfold) test, and will be required to make a minimum of five (5) runs under the observation of IHRA officials . Sportsman licenses may be approved by a Certified Safety Inspector or IHRA Sanctioned Track Operator. Pro licenses can only be approved by Official IHRA Representatives and professional drivers at a 1/4 mile track. All applicants for professional licenses must be at least 18 years old prior to beginning the license procedure. The required solo passes include one moderate pass, two half passes, and two full passes. Parachute must be deployed on the full passes. A driver who is upgrading his license is required to make three runs; one moderate run and two at a speed representative of the class applied for. However, he too may be subjected to the blindfold test by a certified inspector.

An inactive license is defined as any racing memebr that has not utilized their competion license in 3 clandar years.
