Traffic moves on the right, although drivers frequently cross to the left to pass or turn, and motorcycles and bicycles often travel against the flow of traffic. Drivers honk their horns constantly, often for no apparent reason.
Streets in major cities are choked with motorcycles, cars, buses, trucks, bicycles, pedestrians, and cyclos. Outside the cities, livestock compete with vehicles for road space.
Sudden stops by motorcycles and bicycles make driving particularly hazardous. Nationwide, drivers do not follow basic traffic principles, vehicles do not yield right of way, and there is little adherence to traffic laws or enforcement by traffic police.
