The violation will reflect in MOI system within 24 hours. It will not take 3 -4 days because as per my experience recently, somebody (police officer) put a yellow sticker in my car window while it was parked in the parking area along airport road and when I check the MOI website early in the morning today, my violation has reflected there at around 8:04 a.m., dated 22 February 2011 of same day when the sticker has been put in the car.
