The FIA has confirmed that there is to be a track limits clampdown as part of a raft of tweaks made to the Formula 1 regulations.
Following a meeting of the FIA's World Motor Sport Council in Paris on Wednesday, it was announced that the governing body is to respond to growing concerns about drivers gaining advantage by running off track.
The issue became a big talking point in F1 at the Belgian Grand Prix, when there was widespread abuse of track limits at Raidillon, and drivers picking up debris damage was cited as a cause of tyre problems.
In a statement issued after the WMSC hearing, the FIA said: "Sporting Regulations regarding track limits have been clarified and specify that drivers 'must make every reasonable effort to use the track at all times and may not deliberately leave the track without a justifiable reason'.
"Penalties will still be allocated based on whether a driver is judged to have gained an advantage."
Noisier cars confirmed
The WMSC also ratified a technical rule change that should ensure next year's F1 cars are louder.
As Motorsport.com exclusively revealed after the Monaco Grand Prix, F1 teams will have to change exhaust designs next year.
The statement said: "For 2016, all cars must have a separate exhaust wastegate tailpipe through which all and only wastegate exhaust gases must pass.
"This measure has been undertaken to increase the noise of the cars and will not have any significant effect on power or emissions."
There were several other minor rule tweaks announced including:
* The WMSC approved the proposal of the F1 Commission regarding regulations for power unit and gearbox changes. Such penalties prior to qualifying will be applied based on the time of use. For changes made after qualifying, preference will be given to the driver whose team first informed the technical delegate that a change will occur.
* Any driver who causes a start to be aborted, even if he is then able to start the extra formation lap, will be required to start the race from the pit lane. The same process will be applied to a re-start from a race suspension where drivers have been brought to the pit lane.
* The WMSC confirmed a number of clarifications were made to aerodynamic testing restrictions for wind tunnel use and CFD, specifically focusing on reporting and inspection processes for these development tools.
* For 2017, on board cameras on stalks on the nose of cars will be prohibited.
