Details of new Formula 1 radio restrictions for 2016 revealed

Motorsport's world governing body has decided upon stricter enforcement of article 20.1 of the sporting regulations that states "the driver shall drive the car alone and unaided".

It is part of the FIA's stance to ensure all drivers receive as little assistance as possible from the pitwall in future during grands prix in light of the technological advances that have been made over the years.

The following is a list of the permitted messages for 2016, with anything else regarded as a breach of article 20.1:

1. Indication of a critical problem with the car, e.g. puncture warning or damage.*
2. Indication of a problem with a competitor's car.*
3. Instruction to enter the pitlane in order to fix or retire the car.*
4. Marshalling information (yellow flag, red flag, race start aborted or other similar instructions or information from race control).*
5. Wet track, oil or debris in certain corners.*
6. Instructions to swap position with other drivers.*

* indicates these are the only messages that may be passed to the driver whilst he is in the car and on the track, from the time the car leaves the garage for the first time after the pit lane is open on the day of the race until the start of the race.

7. Acknowledgement that a driver message has been heard.
8. Lap or sector time detail.
9. Lap time detail of a competitor.
10. Gaps to a competitor during a practice session or race.
11. "Push hard", "push now", "you will be racing xx" or similar.
12. Helping with warning of traffic during a practice session or race.
13. Giving the gaps between cars in qualifying so as to better position the car for a clear lap.
14. Tyre choice at the next pitstop.
15. Number of laps a competitor has done on a set of tyres during a race.
16. Tyre specification of a competitor.
17. Information concerning a competitor's likely race strategy.
18. Safety car window.
19. Driving breaches by team driver or competitor, e.g. missing chicanes, running off track, time penalty will be applied etc.
20. Notification that DRS is enabled or disabled.
21. Dealing with a DRS system failure.
22. Change of front wing position at the next pitstop.
23. Oil transfer.
24. When to enter the pits.
25. Reminders to check for white lines, bollards, weighbridge lights when entering or leaving the pits.
26. Reminders about track limits.
27. Passing on messages from race control.
28. Information concerning damage to the car.
29. Number of laps remaining.
30. Test sequence information during practice sessions, e.g. aero-mapping.
31. Weather information.

From this weekend's Belgian Grand Prix the FIA has imposed new regulations regarding clutch starts, with a further clampdown due to come into force from 2016.

At present a car is allowed to pull away from the grid via the use of two clutches, and while two will still be allowed in the car for 2016, only one can be used for a start itself, ahead of a standardised clutch being introduced in 2017.
