Having a car in busy Belgrade is often more of a liability than an asset as the traffic is chaotic and parking is limited. The best way to get around the city is on public transport, which consists of buses, trams and trolley buses. It is wise to avoid rush hour. Tickets for all types of transportation can be bought from kiosks in the streets. Taxis are cheap and safe, and can be hailed in the street. Ensure that you pick a licensed taxi; these can be identified by the small blue sign featuring the city's coat of arms and a number.
