15. Penalties during the race
Yes, there are 'stop & go' penalties during the race. If race control see a poor level of driver, or an avoidable accident - then you might be called in for a 'stop & go'. Often it's pointed out during the drivers briefing. Some clubs will handle things differently. At NHRCCC we find applying these in-race penalties effective as well as name-shaming.
Try to redress if you cause an accident, this will generally mean race-control doesn't need to intervien.
