Basic Rules Four laps, clutch start, match decided on race points - 1st 3, 2nd 2, 3rd 1, 4th 0.

Riders are identified by Helmet Colours: Home Riders: Red and Blue, Visiting Riders: Green, Yellow and Black.

Track Signals: Flags displayed during the course of the race mean: Yellow & Black Diagonal Cross - Riders entering last lap. Black & White Chequered - Race finished. Black with accompanying disc - Rider Excluded. Red Lights around the Track - indication that a race has been stopped.

If after the 4th heat a team is 8 or more points in arrears, the Team Manager may either substitute a rider in the next or succeeding heats with another rider in his team as a Tactical Substitute or, if 10 or more points behind, nominate an already programmed Rider for a Tactical Ride. A rider may be used as a Tactical Substitute or take a Tactical Ride once only. Tactical Rides and/or Substitutions must stop when the team is fewer than eight points behind nor are permitted in heat 15.

A Rider nominated for a Tactical Ride, starts from the normal Gate Position on the Start Line, whereas a Tactical Substitute starts on a 15-metre handicap, in both cases any points scored by that Rider is doubled.

All riders (No's 1-7) must have a minimum of three rides prior to heat 15, unless prevented by injury and being declared unfit by Track Medical Officer.

Reserves shall be entitled to maximum of 7 rides, use as a Tactical Substitute, Rider Replacement or in nominated Riders Race, will count in the maximum rides allowed.

In the case that a Rider touches or breaks the Tapes, the Team Manager may, at his discretion, either use a Reserve in the original start position, or re-instate the guilty Rider to re-start on a 15-metre handicap.

Additionally, there will be a further toss of a coin to determine the gate positions for heat 15.
