1. TECHNICAL INSPECTION
1.1. ELIGIBILITY INSPECTIONSANNUAL INSPECTIONS-

Prior to the first time a vehicle is entered into any EVENT for the current season; the
TECHNICAL MANAGER will issue a FORMULA DRIFT VEHICLE IDENTIFICATION (VID)

number/sticker and conduct an annual inspection of each vehicle. Upon verification ofcompliance to the rules, an annual tech sticker will be issued and affixed to the main roll bar
hoop at driver’s left. Only vehicles that have passed the annual Inspection, and have anannual tech sticker affixed, will be allowed to compete unless approved by the TECHNICALMANAGER.

Issuance of the tech sticker is not an endorsement of the performance of the vehicle, nor anindication that the vehicle meets all of the required Technical Specifications. The tech sticker
signifies that the vehicle has passed the initial Safety Inspection and will be permitted to go
on course during scheduled FORMULA DRIFT practice, qualifying and drift sessions.

The annual tech sticker will be withheld from any vehicle that does not comply with therequired Safety Specifications. If the tech sticker is withheld, it is the team’s responsibility tomeet with the TECHNICAL MANAGER to determine what action is required to achievecompliance. The TECHNICAL MANAGER shall maintain inspection records of each enteredvehicle.

To be eligible for competition in an EVENT, all vehicles must have:
A FORMULA DRIFT VEHICLE IDENTIFICATION number (VID)

A current annual technical inspection sticker
EVENT INSPECTIONS-

At a time and place and in a manner determined by event officials, prior to racing activities of
any nature (including without limitation qualifying, competition, practice, testing etc.) all
vehicle and driver equipment must undergo a technical inspection.

In addition, every vehicle is subject to further technical inspection at any time before, during

or after an event, at the time and in the place and manner directed by any event official.

Formula Drift may at any time inspect, seal for inspection, and/ or tear down a participant’s
vehicle. Not complying in full with any inspection request will result in disqualification forfurther competition and such other penalties as deemed appropriate by Formula Drift. All
5

FORMULA DRIFT International Championship2020 PRO Technical Reguｌations International Version 1.1
determinations by event officials regarding the timing and method of technical inspection

shall be final and not subject to appeal or review.

Technical inspection assists event officials with determining, in their judgment, eligibility forparticipation in an event. The technical inspection does not in any way change the fact thatthe driver, the crewmembers, and the vehicle owner are ultimately responsible for the safety
and operation of the vehicle and equipment.

The participant agrees that participant is in the best position to know about the construction
and operation of participant’s vehicle, equipment, and clothing, and whether there has been
compliance with all Formula Drift rules, regulations and agreements, including but notlimited to those contained in the Rulebook. Moreover, in the case of technical violations, theparticipant acknowledges, understands and agrees that the participant is charged with fullknowledge of every component of participant’s vehicle and that even if a third party hascaused the participant’s vehicle to be noncompliant, the participant will still be responsible

for and charged with any applicable violation and sanction. Disclaiming knowledge of theparticular part or parts, or disclaiming knowledge of the rule or rules, or disclaiming

responsibility for the actions of the third party, will not be defenses to any violation or any
sanction therefor.

RETENTION OF VEHICLES AND PARTS-

Participant hereby grants Formula Drift, and each of their agents and assigns, full andunconditional permission to collect and retain vehicles, parts of vehicles, equipment, or any

other Items used in conjunction with participation that are owned by or in the possession ofparticipant or present at an event (collectively “Items”), including such Items that may be

relevant incident to the investigation of an incident; the inspection or testing of such Items;
or for any other purpose. Formula Drift may exercise this right to take and retain Items at

any time when Formula Drift determines in its sole and absolute discretion that such actions

are necessary. Participant fully releases Formula Drift from any liability whatsoever for loss of,damage to, or destruction of any such Items. When an item is suspected of being out ofcompliance with an Formula Drift rule, or when an item has been involved in an incident,

Formula Drift may in its sole and absolute discretion collect and retain such Items if Formula

Drift believes it necessary to do so to further investigate, make a final determination, and/or
preserve evidence, all in Formula Drift’s sole and absolute discretion. At any time that

Formula Drift collects and retains Items, Formula Drift will try to safeguard such Items andreturn such Items when Formula Drift has completed its work with them, but Formula Drift
6

FORMULA DRIFT International Championship2020 PRO Technical Reguｌations International Version 1.1
makes no representation or warranties that the Items will not be lost, damaged, destructively
tested, destroyed or otherwise affected. Formula Drift is not responsible for payment,
reimbursement, damage or loss to the participant as a result of compliance testing. If

Formula Drift believes that an item should be retained or destroyed, or indefinitely or

permanently retained, to prevent further use of such item in competition, Formula Drift may

so retain or destroy such item.

PARTICIPANT OBLIGATIONSParticipants must take whatever steps are requested by a Formula Drift Official, including
tear down of the vehicle and removal of parts to facilitate inspection of race equipment. Thisobligation includes, but is not limited to, installing inspection holes, inspections ports,
and/or other means of inspections in the frame, roll cage bars, suspension

components, and the like. Formula Drift is not responsible for payment, reimbursement,
damage or loss to the participant as a result of such inspections.

1.2. MODIFICATIONS

Any vehicle which after being issued an annual technical inspection sticker by the TECHNICALMANAGER is dismantled, or modified, or in any way changed which might affect its safety orcall into question its eligibility, or which is involved in an accident with similar consequences,must be re-presented by the team for approval. It is the responsibility of the team to notify
the TECHNICAL MANAGER of any modifications.

1.3. DAMAGE

If a vehicle is damaged due to an accident or other incident, the TECHNICAL MANAGER may
remove the annual tech sticker. A new tech sticker may be issued after the vehicle is re-inspected or repaired and then re-inspected. It is the responsibility of the team to notify the
TECHNICAL MANAGER of any and all damage.
