Kimi Raikkonen has backed the decision to limit the use of DRS for the 2013 F1 season - arguing that it was a sensible decision to improve safety.

While use of the system - which allows drivers to get a boost in performance by opening a flap on the rear wing - has always been restricted to a certain area of the circuit during a race, it had been available more freely in both practice and qualifying.

However, the final World Motor Sport Council meeting of the year saw the FIA decide to ban the free use of DRS in practice and qualifying and instead impose the same restrictions that are in place on race day, a move Raikkonen said was wise to improve safety.

"It's a sensible change," the Lotus ace was quoted as telling Turun Sanomat. "It had been going more and more in the direction of everyone trying to take advantage all the time to use DRS earlier and earlier. At some point it was going to cause a big crash. The drivers wanted this change."

Raikkonen also said it could close things up amongst the leading cars.

"Probably it will stabilise the better cars," he said, "where for example the Red Bulls were able to drive through some corners with the DRS open, while others could not."
