What is technical non-compliance in INDYCAR?

Section 7: Violations/Penalties

A car that fails pre-event, post-qualifying, or post-race technical inspection can lose its qualifying time, be sent to the rear of the grid, lose points, or be disqualified, depending on the severity of the breach.
Use of non-homologated or modified components outside the rulebook's allowances is a serious technical violation.

Avoidable contact: Contact judged to be avoidable that affects another competitor draws penalties ranging from a position penalty to a drive-through.
Blocking: Reactive moves to defend position that force another driver to take evasive action are penalized.
Jumping a start or restart / passing before the line: Improving position before the start/finish line or restart zone draws a penalty.
Ignoring flags or the black flag / failing to follow Race Director instructions: Penalized, and continued non-compliance can lead to disqualification.
Track limits: Repeatedly exceeding track limits to gain an advantage is penalized on road and street courses.

Pit speeding: Exceeding the pit-lane speed limit draws a time or drive-through penalty.
Unsafe release: Releasing a car into the path of another, or work done outside the assigned box, is penalized.
Equipment, fueling, and crew-over-the-wall infractions carry defined penalties.

In-race penalties include drive-through penalties, stop-and-hold penalties, and time penalties; grid penalties apply to qualifying offenses.
Post-event sanctions include fines, points deductions, probation, suspension, and disqualification.
The Race Director may apply penalties during the race; the stewards review incidents and certain penalties may be appealed under the rulebook's procedures.
