What are the maximum and minimum driving speeds for two, three, and four lanes respectively?

Starting from the left, the general speed limit regulations are as follows: First lane: 100-120 km/h (usually dedicated to passenger cars); Second lane: 80-100 km/h; Third lane: 60-100 km/h; Fourth lane: emergency lane. Below is more information about road classifications: 1. Classification perspective: Functional grades are divided into expressways, first-class roads, second-class roads, third-class roads, and fourth-class roads, totaling five grades; Administrative level grades are divided into national roads, provincial roads, and county roads; The classification by speed terms is expressways, fast roads, and ordinary roads, totaling three categories. 2. Road composition: The main components of a road include the roadbed, pavement, bridges, culverts, ferry docks, tunnels, greening, communication, lighting equipment, and other facilities along the route. 3. What is a road: A road refers to a route built according to national technical standards that connects cities, urban and rural areas, villages, and industrial and mining bases, and is approved by the road administration department. It includes expressways, first-class roads, second-class roads, third-class roads, and fourth-class roads, but does not include naturally formed paths in fields or rural areas. It is mainly for motor vehicle use and meets certain technical standards and facilities.
After driving for so many years, I often travel on various roads. Two-lane roads are mostly rural paths or narrow city streets, with a maximum speed limit generally set at 60 kilometers per hour. There's no strict minimum speed, but for safety, it's advisable to maintain at least 40 km/h to avoid rear-end collisions. Three-lane roads are slightly wider, like those in urban-rural fringe areas, with a maximum speed of up to 80 km/h and a recommended minimum of 60 km/h to avoid slowing down traffic. Four-lane roads are usually highways or expressways, with a maximum speed limit of 120 km/h and a legal minimum of 60 km/h—driving too slow might attract police attention. I remember once during a road trip, driving too slow on a two-lane road in the rain nearly caused an accident, so minimum speeds should also consider weather conditions; on sunny days, it can be slightly higher. More lanes do make driving smoother, but don't speed—safety comes first. Different road sections may have different signs, so it's best to check maps or navigation alerts in advance.
As a father of two, safety comes first when driving. On two-lane roads, the speed limit is often 50 to 60 kilometers per hour, with a minimum safe speed of at least 30. Avoid sudden braking to protect the kids. On three-lane roads in suburban areas, the maximum speed can go up to 70 or 80, while maintaining a minimum of around 50 ensures stability. On four-lane highways, the maximum speed is 120, and the minimum must be above 60—going too slow may cause chain collisions. I often observe while driving my kids: fewer lanes mean slower speeds for safety, while more lanes require cautious acceleration, especially in rainy weather—don’t take risks. The key to minimum speed is maintaining distance; on highways, speeds below 60 will trigger warning signs. When traveling with kids, I always remind myself to control the throttle—even on wide roads, don’t forget speed bumps.
