Roads are narrow and poorly maintained. Only some major highways are paved. Roads in southern Sudan may be impassable during the rainy season, while roads in the north can be quickly covered with shifting sand at anytime during the year. Nighttime driving throughout the country is dangerous and should be avoided if possible because vehicles often operate without lights or park in the road without warning. Ambulance and road emergency services are available in major urban areas, but the are extremely limited or unavailable elsewhere in the country.
Public transit is limited except in and between major urban areas.
Passenger facilities are basic and crowded, especially during rush hours or seasonal travel. Schedules are unpublished and subject to change without notice. Vehicle maintenance does not meet the same standards as those in the United States or other Western countries. There is regular passenger train service from Khartoum to Wadi Halfa and Port Sudan. Inter-city bus service between major cities is regular and inexpensive.
