Drivers drafted in mid-season will be allowed to test for one day under new rules for F1 2010, it has been confirmed.
According to reports by SpeedTV.com
any driver that has been out of the sport for two years would be allowed to test.
The test though must take place at a non-grand prix venue, and if that debut is then canned, the team will be penalised by a reduction of one day from its pre-season track testing days available in the following year.
The change has been brought in as the ban on in-season testing - something that will remain in 2010 - created a number of issues for new or returning drivers in '09, such as Jaime Alguersuari, who Scuderia Toro Rosso brought in to replace Sebastian Bourdais, as well as Michael Schumacher, who was forced to test a 2007-spec Ferrari F1 car while assessing his ability to stand-in for the injured Felipe Massa.
Meanwhile, in a separate, but related development, the number of in-season aerodynamic test days allowed has been cut from eight to six.
"Any of these days may be substituted for four hours of full scale wind tunnel testing to be carried out in a single twenty four hour period," added the sports governing body.
