A new traffic restriction went into effect officially in Beijing on Monday, which is expected to bring back the clear skies seen during the Olympics. Cars whose number plates end with 1 or 6 will be banned from running on roads within the Fifth Ring Road inclusive on Mondays, while those ending with 2 or 7 will be banned on Tuesdays, 3 or 8 on Wednesdays, 4 or 9 on Thursdays and 5 or 0 on Fridays. The ban does not apply on weekends. The new restrictions will be implemented on a trial basis for six months until April.
