Casablanca is a large and chaotic city and first-time visitors may find getting around a daunting prospect. Fiat Uno taxis provide metered services in the central metropolitan areas. Registered taxis can be easily hailed from just about anywhere in the city and are easily identified by their red colour. There are also bigger, white taxis available. Both kinds are usually shared and the drivers may wait till the vehicle is full before setting off, or stop en route to pick up more passengers. The white taxis can also be hired by the hour or day and many travellers choose to do this. Keep in mind that a large surcharge goes into effect later into the evening, making taxi fares much higher at night.Casablanca does have a bus system; however, it is often confusing for visitors as there are many companies operating on different routes, at varying prices, and on unreliable schedules. Rental car agencies can be found throughout the city, but those opting to drive themselves should be cautious due to chaotic driving conditions and high accident rates. Visitors might choose to forego the buses and car hire in favour of the trams which cover most of Casablanca and are new and efficient.Despite the apparent chaos, many of the main sights and attractions of Casablanca are situated close together and can be explored on foot. When travelling by means of public transport and when walking, travellers should not display wealth and should try not to draw attention to themselves.
