HTCNZ events are strictly non-contact competitive racing. It is acknowledged that accidents can occur. However, if a driver is identified to use their car in a reckless manner which leads to an unnecessary accident, this will be treated seriously by the HTCNZ committee. This may result in the disqualification of the individual from racing in the rest of the weekend event. With serious or repeated reckless driving this may result in the cancellation of the drivers membership in the HTCNZ association.
