NEW REGS AGAIN, ONLY BETTER
New regulations are out, with a couple of amendments to make them more user-friendly. E and G no longer merging is the big news, which appears to have stopped the mass class E exodus that was in motion. Common sense prevails?

Operation of Safety Car
3.14 Operation of Safety Car
3.14.1 The Safety Car will be brought into operation & run in accordance with Section G, Appendix 2 of the MSA General Regulations. to neutralise a race upon the sole decision of the Clerk of the Course. The Safety Car will be driven by an experienced circuit driver (in accordance with GR B27) and will carry an observer capable of recognising all competing cars and who is in permanent radio contact with race control.
The Safety Car, yellow/amber lights illuminated, will normally join and exit the circuit from the pit lane and the Safety Car boards will be shown initially from the start-line. If these locations are to be varied specific written instructions and verbal briefings will be issued detailing the exact locations to be used.
On the order from the Clerk of the Course, the Safety Car will join the circuit with its revolving lights on, regardless of where the race leader is.
3.14.4 When the order is given to deploy the Safety Car a waved yellow flag and "SC" board will be displayed at the start finish line. The waved yellow flags and "SC" boards will flow around the circuit in both directions, as an adjacent post displays both their waved yellow flag and "SC" board. This system may be supplemented by a message being simultaneously broadcast to all marshals’ posts if such a communication system is available.
3.14.5 Flashing yellow lights may also be used at the start-line and at other points around the circuit.
3.14.6 All competing cars, when notified of the Safety Car intervention (by the flag signals, "SC" boards, or by any other means) will reduce speed and line up behind the Safety Car, no more than 5 car lengths apart, and maintaining the same speed as it. Overtaking or overlapping of any other competing car during a Safety Car intervention is forbidden. Overtaking of a Safety Car is forbidden unless the particular competitor concerned is signalled to overtake the Safety Car by the observer in the Safety Car.
3.14.7 When ordered to do so by the Clerk of the Course, the observer in the Safety Car will wave past any cars between the Safety Car and the race leader. These cars will continue at reduced speed and without overtaking until they reach the line of cars behind the Safety Car.
3.14.8 While the safety car is in operation, competing cars may enter the pit lane, but may only rejoin the track when signalled to do so and not when the safety car and the line of cars following it are about to pass or are passing the pit exit. A car re-joining the track must proceed at an appropriate speed until it reaches the end of the line of cars behind the Safety Car.
3.14.9 The Safety Car will remain in operation until at least the majority of competing cars on the circuit are lined up behind it.
3.14.10 When the Clerk of the Course calls in the Safety Car it will extinguish the yellow/amber flashing lights prior to exiting the circuit. This would normally be such that a minimum of 25% of a lap for circuits over 2 miles and 50% of a lap for circuits under 2 miles should be completed by the Safety Car with its lights extinguished.
3.14.11 Following the safety car extinguishing its lights, and prior to passing the green flag, the race leader will maintain the pace set by the Safety Car. The race leader will dictate the pace and, if necessary, fall more than five car lengths behind it. In order to avoid the likelihood of accidents before the safety car returns to the pits, from the point at which the lights on the car are extinguished drivers must proceed at a pace which involves no erratic acceleration or braking nor any other manoeuvre which is likely to endanger other drivers or impede the restart.
3.14.12 As the Safety Car is approaching the pit entry, the green flag will be displayed at the start finish line and the "SC" board withdrawn. Following this display of the start signal yellow flags and "SC" boards at the marshals posts will be withdrawn and be replaced with a waved green flag for one lap. The waved green flag will flow around the circuit in both directions, as an adjacent post displays their waved green flag. This system may be supplemented by a message being simultaneously broadcast to all marshals’ posts if such a communication system is available. Overtaking remains strictly forbidden until the start signal is passed.
3.14.13 Each lap covered while the Safety Car is in service will be counted as a race lap unless specified to the contrary in Championship regulations.
3.14.14. Under certain circumstances the Clerk of the Course may ask the Safety Car to use the pit lane. In this case, and provided its yellow/amber lights remain illuminated, all cars must follow it into the pit lane without overtaking. Any car entering the pit lane under these circumstances may stop at its designated garage area.
