You can park on most side-streets. Shopping malls, hotels, and the busier parts of town have car/bike parking.
If you see red and white stripes painted on the curb, this means NO PARKING.
If you see yellow and white stripes painted on the curb, this means STANDING ZONE – you can only stop there a short time.
People at the side of the road blowing whistles indicate usually that a car is reversing, or that this is a no standing zone and you should move along.
There are also streets with NO PARKING during rush hour, and even streets (like the alleyways off Nimmanhaeminda Rd) where you park on one side on odd days and the opposite side on even days of the week. In these cases, the best thing to do if you are unsure is to follow where other scooters park.
