Which Side is the Slow Lane and Fast Lane on the Highway?
1 Answers
When driving on a highway, in the case of two lanes in the same direction, the fast lane is the left lane, and the slow lane is the right lane. For three or more lanes in the same direction, the fast lane is the leftmost lane, the driving lane is the middle lane, and the slow lane is the rightmost lane. Additional Information: Highway: Highways are classified as high-grade roads, abbreviated as expressways. According to the "Technical Standards for Highway Engineering" by the Chinese Ministry of Transport, a highway is defined as "a road that can accommodate an average annual daily traffic volume of over 25,000 small passenger vehicles, is exclusively for high-speed divided-lane automobile traffic, and has fully controlled access." Although different countries have varying names for highways, they all refer to roads with four or more lanes, bidirectional separated traffic, fully controlled access, and all-grade interchanges. Restricted Traffic, Automobile-Only: Highways prohibit pedestrians, non-motorized vehicles, tractors, electric vehicles, agricultural transport vehicles, wheeled special machinery, full-trailer tractors, and motor vehicles with a design speed below 70 km/h. Only automobiles are allowed. China also specifies that the design speed of highways is generally 120 km/h. Controlled Access, "Closed" Except at Entrances and Exits: Non-motorized vehicles, pedestrians, and livestock are restricted from entering highways through measures such as barriers, high embankments, and guardrails to "close" the highway. For intersections where vehicle access is not permitted, grade-separated interchanges are installed for isolation. For intersections where vehicle access is allowed, designated interchange ramps are used for connection. Separated Traffic, Safe and High-Speed: Highways adopt a dual-carriageway form with a central median to separate opposing traffic flows, thereby preventing head-on collisions. For traffic in the same direction, lane markings are used throughout to divide lanes, reducing interference caused by overtaking and varying speeds in the same direction, which facilitates high-speed and safe driving.
