[ol]
[li]More than one change of direction to defend a position is not permitted. Any driver moving back towards the racing line, having earlier defended his position off-line, should leave at least one car width between his own car and the edge of the track on the approach to the corner.[/li]
[li]Any driver defending their position on a straight, and before any braking area, may use the full width of the track during his first move, provided no significant portion of the car attempting to pass is alongside his.[/li]
[li]For the avoidance of doubt, if any part of the front wheel of the car attempting to pass is alongside the rear wheel of the car in front this will be deemed to be a ‘significant portion’.[/li]
[li]Blocking is not permitted at any time.
[ol]
[li]Any deviation by a driver from the racing line, that is a reaction to a move from the trailing driver which impedes the trailing drivers forward progress, is not permitted at any time.[/li]
[li]You are entitled to choose your racing line, and positioning your car on the inside line is a fair manner to defend your position. However, you must position your car on this defensive line before the trailing driver attempts to pass you, and not as a reaction to his attempt.[/li]
[li]The ahead driver must not make any malicious or inappropriate braking or slowing manoeuvres. Leading drivers must never 'brake test' the car(s) behind them, swerve in a braking zone, or try to break a tow. The leading driver is entitled to be slower or use longer and earlier braking zones than the trailing driver. They are also entitled to use whichever racing line they choose.[/li]
[/ol]
[/li]
[li]Manoeuvres liable to hinder other drivers, such as deliberate crowding of a car beyond the edge of the track or any other abnormal change of direction, are not permitted.[/li]
