( CNN ) -- Formula One drivers will face tougher penalties for improper driving in the 2011 season , while race stewards will have more power to hand out sanctions . Stewards were already able to issue drive-through and 10-second penalties or a drop of any number of grid positions , and they will now be able to exclude drivers from race classification and suspend them from future grand prixs . The changes were released by ruling body the FIA in the wake of last Friday 's World Motor Sport Council meeting in Monaco , at which the 2011 regulations were set . The FIA also released details of driving practices it considers improper , including more than one change of direction when defending track position . It also announced that backmarkers -- cars at the rear of the field who have been lapped by faster drivers -- will have to move aside for leading racers , or face being reported to the stewards . F1 bosses drop ban on team orders . Another change for the forthcoming season is the introduction of a curfew on team personnel , which will prevent mechanics working on their cars through the night on a race weekend . The curfew will be between midnight and 6 a.m. ahead of practice on a Friday and between 1 a.m. and 7 a.m. before qualifying on a Saturday . Each team will be allowed to break the curfew on four occasions throughout the season . The 2011 season will begin with the Bahrain Grand Prix on March 11-13 .
