"Whenever you plan to cross Juhu signal, you should always say 'Jai Farahji' and you would never find any traffic. I just did it and the signal is all clear," Sonu tweeted.
"That's the power of Farah Khan...Smooth sailing traffic today...Jai Farahji," he added.
"Happy New Year", which also features Shah Rukh Khan and Deepika Padukone in the lead roles, will hit the screens Oct 23. Boman Irani and Abhishek Bachchan will also be seen in the film.
