What are the speed limits for the four lanes on a highway?

[DeJesse]

Highway four-lane speed limits are as follows: 1. The first lane from left to right: 100-120 km/h. Generally reserved for passenger cars. 2. The second lane: 80-100 km/h. 3. The third lane: 60-100 km/h. 4. The fourth lane: Emergency lane. Some highways may have different regulations, so always follow the marked speed limits on the road. When driving on a highway, pay attention to the following: 1. Always adhere to the speed limit. The maximum speed limit on Chinese highways is 120 km/h, and different lanes may have varying speed limits, which are indicated by roadside signs. Speeding is a major cause of accidents, so avoid it at all costs. At the same time, avoid driving too slowly, as this can disrupt normal traffic flow. 2. When entering the main lane from an on-ramp, use the acceleration lane to reach an appropriate speed before merging. Do not obstruct vehicles already in the main lane. 3. Clearly distinguish the purpose of each lane and drive accordingly. Generally, stay in the main lane and only use the overtaking lane when necessary to ensure smooth traffic flow. 4. Follow speed limit regulations. Speeding can lead to accidents, while driving too slowly can hinder other vehicles. Reduce speed during rainy conditions. 5. Always watch for roadside and overhead signs and markings. Stay slightly to the right to avoid crossing the right lane divider, giving overtaking vehicles sufficient side clearance.
