Rules

The Junior Dragster program is designed to allow youth, as young as 8 years of age and up to 17, the opportunity to race against their peers in the replicas of the models
that the Pros drive. Juniors may compete through the calendar year of their 18th birthday, provided they are in competition between January 1 and their birthday.
IHRA Junior Dragsters are restricted to competition in half-scale cars over a distance of 1/8 mile. The competition structure is designed to be conducted on an ET
dial-your-own format, or preset index on a heads-up breakout basis (much like IHRA’s Quick Rod class). Functional taillight mandatory on all entries. A photocopy of
every competitors birth certificate must accompany all license applications along with an original parental confirmation agreement and original release and waiver of
liability. Competitors must make 6 passes to obtain or upgrade IHRA license. (2 launches, 2 half track and 2 full passes within ET range for respective license).

Class Designations
BEGINNER:
Age 8 or 9 only; ET restricted to 12.90seconds or slower based on either ET dial-your-own or heads-up basis. Breakout rules apply. One warning will be issued if a
competitor runs quicker than 12.70. If the competitor does this a second time at the same event, they will be disqualified from the event. Any competitor running
quicker than 12.50 at any time will be disqualified for the remainder of the event.

ADVANCED:
Age 10 to 17; modified engines meeting IHRA rules accepted. Class based on either dial-your-own ET or heads-up Pro start. ET restricted to 8.90 or slower. Breakout rules
apply. One warning will be issued if a competitor runs quicker than 8.70. If a competitor runs quicker than 8.70 a second time, at the same event, they will be disqualified
for the remainder of the event.

MASTER:
Age 12 to 17; must meet all requirementsfor Advanced, PLUS: minimum 1 full licensed competition season mandatory; the competitor must provide documentation of
experience and submit it with all license applications, licensing by IHRA or Track official after 3 approved runs between 7.90 and 8.90); 3.2A-1 jacket and 3.2A-1 pants
required; full face helmet, rack & pinion steering, and steel brake lines mandatory. ET 7.90 or slower; maximum speed of 85 mph: One warning will be issued if a
competitor runs an elapsed time of 7.850 or quicker. If a competitor does this a second time at the same event they will be disqualified for the remainder of the event
and their license will be suspended for 1 calendar year from the date of the infraction.

Due to the radical combinations available, additional safety requirements may be mandated if deemed necessary by the technical department.

STARTING PROCEDURES
All juniors may not be fired until ready to go into the burnout box. Juniors must be at the head of staging and waiting for the signal to start. Under no circumstances
should the junior be started at the rear of staging and driven forward to the burnout box.

RESTARTS
After initial start-up, one chance will be given to restart the car within a reasonable time at the starter’s discretion. The crew person should keep the starter close by in
case its needed.

Push starting anyvehicle is prohibited.

STAGING
Once an entry reaches the front of the staging lanes for a run, it must be prepared to fire and race. In order to be a legitimate race winner, the competitor must start,
self stage the vehicle and take the green light. This rule also applies to single runs. All competitors will be given one chance to re-fire their entry, provided no part of the
vehicle is past the ready line. Crew members are prohibited from touching the vehicle once it reaches the “ready line” or cone. The ready line will be clearly identified by
orange cones places adjacent to the track surface prior to the staging area 10ft from the beam. Once any portion of the vehicle crosses the ready line, re-starting is
prohibited.

Crewmembers touching the vehicle past the ready line will result in disqualification.

STAGING: “Auto Start” will be used in all classes at National Events. Once both cars are pre-staged and the first car fully stages, the second car has a predetermined
amount of time (15 seconds) to stage before the tree is automatically activated. This predetermined amount of time is referred to as “Time Out”. If the second car fails
to stage before the system ”Times Out”, it will be given a red light. If either car rolls deep after “Auto Start” has been activated, the competitor accepts the deep staging
and will not be pulled back.

“CourtesyStaging” is mandatory at all Junior events in all categories. If a competitor unintentionally lights both bulbs before the opponent stages, the starter will pull the
vehicle back and allow to re-stage. This is considered a pull back and will only be permitted one time.

DEEP STAGING: Is allowed but not guaranteed. If a car wishes to deep stage, they must clearly write the word “deep” on both sides of the entry in clear view to the
starter and control tower. The Auto starter system will be activated when both cars are pre-staged, so if you are staging deep you should do it in a timely fashion.

Crew member may assist the entry in the pre-staging of the vehicle. Once the entry is pre-staged, crew members must be behind the vehicle and out of both
competitors view.

Pull Backs in the case of complete over staging are permitted one time if time permits. If the auto start system cycles during the pull back, the run will stand. If a car
deep stages accidentally, there will be no pull back.

THE FINAL STAGING MOTION, USING APPLIED POWER, MUST BE IN A FORWARD MOTION GOING FROM PRE-STAGE TO STAGE.

SUPPORT GROUP

COMMUNICATIONS: 2-way radios prohited.

COMPUTERS: Prohibited. See General Regualtions for specific information.

DATA RECORDERS: Permitted. May be utilized to record engine RPM, cylinder head and exhaust temperature. No sensor of any type may be used on the front wheels or
spindles. All data recorders and related components including switches, push buttons and wires must be located outside of the drivers compartment and isolated from
the drivers view. Data recorders may only be activated by a crew member and must be done before the entry reaches the ready line of the cone. The units may not
display any information to the driver or remote location. A tachometer that incorporates download capabilities is classified as a data recorder. (See General Regulations:
Data Recorders/Electronic Devices for specific information.)

GAUGES: Engine and cylinder head temperature gauges are permitted. A tachometer meeting specific guidelines is also permitted. (See General Regulations: Data
Recorders/Electronic Devices for specific information).

STAGING DEVICES: Mechanical, hydraulic, electric or pneumatic staging systems prohibited.

TIRES & WHEELS
TIRES: Rear tires; 18” diameter x 7 ˝" wide minimum, measured at widest or tallest point. All front tires must have a manufacturer’s maximum inflation rating. Tires
may not be inflated above manufacturer’s rating. All tires must be pneumatic. No solid tires. Treatment of tires in the lanes, burnout area or starting line is not permitted
and tire covers must be removed before entering staging lanes.

WHEELS: Front wheels, five-inch diameter minimum with a minimum spindle diameter of ˝”. Front spindle must be able to retain a cotter pin, or use a nylon locking-type
nut, Rear wheels, eight-inch diameter minimum. No modifications allowed to any wheels.
TOWING

Tow vehicles in the form of golf cart, three or four-wheel support vehicle is mandatory. Full-size tow vehicles prohibited. Driving of Jr. Drag Racing vehicle through pits is
prohibited. Tow vehicle to be operated “ONLY’ by an adult or street-licensed individual. Any time a Jr. Drag Racing vehicle is being towed, the driver must be seated in the
cockpit. No passengers. The tow strap may not be attached to any point of the roll cage. It is recommended that all entries utilized a fluorescent or brightly colored flag
attached to the entry any time the vehicle is being towed. Minimum height of flag is five feet. The junior must be either towed from the top end of the track or pushed
from the base of the timing tower back to their pit stall.

WARM-UPS
Any time a car is started, whether in the pits or in the staging lines, a qualified driver must be seated in the vehicle.
