U.S. citizens who are also Malaysian nationals could experience close scrutiny by suspecting Malaysian immigration officials when entering or departing Malaysia on Malaysian passports. Note that the United States requires all U.S. citizens to enter and depart the U.S. on U.S. passports. Dual nationals may be subject to Malaysian laws which impose special obligations. Traffic patterns in Malaysia move on the left. When crossing roads, pedestrians are reminded to look carefully in all directions.
Motorcyclists attempt to circumvent traffic blockage by weaving through vehicles and pedestrians.
Traffic is heavy at peak hours and slows down considerably when it rains. Bottlenecks are common sights in Kuala Lumpur. Multilaned highways often merge into narrow two-lane roads in the center of town and cause added congestion. Many narrow and winding streets were built a century ago to handle hawkers and trishaws. Development of the infrastructure has not kept pace with the proliferation of motorized vehicles.
