Formula One teams took a vote, Saturday night in Montreal, over in-season testing, and agreed to its return.
The plan drafted by the teams still needs to meet the approval of the World's Motor Sport Council, which could come at the next meeting later this month, but would allow four two-day sessions to take place on grand prix sites after a race.
According to early reports, Barcelona and Silverstone are the preferred venues for in-season testing, but Budapest and Spa are also on the short list of favoured tracks.
Officials need to see the final 2014 race calendar to validate the test schedule, because a test cannot be held between two back-to-back grands prix.
Furthermore, three additional pre-season tests are scheduled, of which two could be staged in Bahrain, again if the calendar permits.
