The FIA has confirmed that races will restart from a standing start following safety car periods in 2015.
After the idea was raised during an F1 Commission meeting last week, the World Motor Sport Council (WMSC) has ratified the change in regulations in a meeting in Munich on Thursday. The only time standing restarts will not be used will be if the safety car is deployed in the opening two laps or within five laps of the finish of the race.
Standing starts are one of a number of changes to the regulations next year, with testing to be reduced once again. The three four-day pre-season tests are only permitted to take place in Europe and will be reduced to two four-day tests in 2016. Next season will also see a reduction of in-season testing from four tests to two; each consisting of two days. Two of the four days will have to be allocated to young drivers.
Teams will also face new wind tunnel restrictions relating to the amount of permitted hours per week - reduced from 80 to 65 - with wind-on hours being lowered from 30 to 25 hours per week.
The number of power units that each driver is permitted to use has been reduced to four for next season, although that will increase to five if the calendar consists of more than 20 races. If a driver changes a complete power unit he will have to start from the back of the grid rather than the pit lane.
Other changes to the sporting regulations see part ferme rules imposed from the start of FP3 rather than the start of qualifying, while the Friday night curfew has been increased from six to seven hours and will rise to eight in 2016.
The ban on tyre blankets has also been dropped for 2015, with the FIA adding that "This will be re-discussed if and when the wheel and tyre diameter increases in the future."
Technical changes will see "A number of new regulations for the noses to ensure improved safety and to provide more aesthetically pleasing structures", while atwo-stage wheel fastener retaining system is now compulsory.
