What are the speed requirements for the four lanes on the highway?

[RyderMarie]

On a four-lane highway, the speed limits for each lane are as follows: the first lane is 100-120 km/h (usually reserved for small passenger vehicles), the second lane is 80-100 km/h, the third lane is 60-100 km/h, and the fourth lane is an emergency lane. Precautions for driving on the highway: Always strictly adhere to the speed limits. The maximum speed limit on China's highways is 120 km/h, and different lanes may have varying speed limits depending on the situation. When entering the main lane from an on-ramp, if there is an acceleration lane, use it to increase your speed to an appropriate level before merging. When merging, do not obstruct vehicles already traveling in the main lane. Clearly distinguish the function of each lane and drive accordingly. Generally, stay in the main driving lane and only use the overtaking lane when passing other vehicles to ensure smooth traffic flow. Always pay attention to roadside and overhead signs and markings. Drive slightly to the right to avoid running over the right lane divider, providing sufficient lateral distance for vehicles behind to overtake safely.
