Iraq's highways are considered dangerous.
Highway 10 between Baghdad and the Jordanian border is especially hazardous, particularly around the Ramadi area. Armed bandits operate this route, using fast cars to stop large convoys of vehicles. Highway 8, between Baghdad and Hillah is also considered a no go route by humanitarian organisations. Highway 1, between Baghdad and Qasim is also very dangerous.
Police are present on the streets of the capital but they are Out-gunned and outnumbered.
