What is the speed limit on internal market roads?

[KingDella]

Motor vehicles driving on roads must not exceed the speed indicated by speed limit signs or markings; on urban roads with two or more motor vehicle lanes in the same direction and without speed limit signs or markings, the maximum speed is 70 kilometers per hour, while on closed motor vehicle-only roads and highways, the maximum speed is 80 kilometers per hour. Maximum speed of 30 kilometers per hour: Low-speed trucks, three-wheeled vehicles, tractors, battery-powered vehicles, wheeled special machinery vehicles, regular three-wheeled motorcycles, and mopeds must not exceed 30 kilometers per hour when driving on roads. The following behaviors are prohibited: Driving with doors or compartments not properly closed; hanging or placing items within the front or rear windows of the motor vehicle's cab that obstruct the driver's view; making or receiving handheld phone calls, watching TV, or engaging in other behaviors that hinder safe driving; stalling or coasting in neutral when going downhill; throwing items onto the road; driving a motorcycle with hands off the handlebars or hanging items on the handlebars.
