British teenager Daniel Ticktum has been hit with a two-year racing ban by UK governing body the Motor Sports Association for what it deemed "a disturbing and dangerous episode".
Ticktum overtook 10 competitors under safety car conditions to catch and crash into MSA Formula championship rival Ricky Collard in race three at the Silverstone round.
The 16-year-old may not hold a UK or international competition licence until the end of the ban, the second year of which is suspended for 12 months "on the condition there are no further offences".
Championship stewards excluded Ticktum from the Silverstone meeting, taking the Fortec driver to 12 penalty points and an automatic three-month ban after also committing a six-point offence at Croft earlier in the season.
The incident, after which both Ticktum and Collard eventually retired, has since been reviewed at a meeting of the Motor Sports Council National Court.
In his report court chairman Guy Spollon described how Ticktum, after a first-lap collision with Collard had dropped him to the back of the field, passed 13 yellow flags, four double-yellow flags, two white flags and 15 safety-car boards to catch back up to his rival during the safety-car period.
Spollon labelled Ticktum's actions "totally irresponsible and reprehensible in the extreme".
The ban is effective from September 27 2015, with the first 12 months beginning immediately and absorbing the three-month ban issued by the Silverstone stewards.
In the wake of the Silverstone incident Ticktum issued the following statement to Autosport: "Not only have I let myself down but more importantly I have let down so many people that are close to me too.
"I want to apologise to my fellow drivers all those people who have supported me in the motor racing community. I also want to apologise to all the marshals and MSA officials at Silverstone this weekend.
"I have been a fool and I intend to learn the important lessons I need to from this weekend."
Ticktum must retake his ARDS test before returning to racing and has been ordered to pay £2000 towards the costs of the hearing.
It is understood he had been evaluating a move into Formula Renault 2.0 or Formula 3 in Europe for next season.
The ban does not preclude him from testing.
