Amman is a relatively small city and is thus easy to navigate. Metered private taxis are available at reasonable prices, and white shared taxis cover fixed routes. Locals are usually very friendly and helpful regarding directions and drivers are usually forthcoming about route information. Municipal buses travel along most routes in Amman; although they are efficient and safe to use, most routes are only written in Arabic and they are not popular with visitors. Car hire is available and offers a viable means of exploring the city; it's a good idea to hire a vehicle with a driver, which usually comes at an extra cost.
