The speed limits for three lanes in the same direction are as follows: the minimum speed for the leftmost lane is 110 kilometers per hour, the minimum speed for the middle lane is 90 kilometers per hour, and the minimum speed for the rightmost lane is 60 kilometers per hour. 1. Exceeding the speed limit by less than 10%: no fine, but 3 points deducted. 2. Exceeding the speed limit by more than 10% but less than 20%: a fine and 3 points deducted. 3. Exceeding the speed limit by more than 20% but less than 50%: a fine and 3 points deducted. Exceeding the speed limit by more than 50% but less than 70%: a fine and 6 points deducted, and the driver's license may be revoked.

After driving on highways for so many years, I know exactly how the speeds are divided across the three lanes. The left lane is the fast lane or overtaking lane, where speeds are usually close to the maximum limit, such as 120 km/h, specifically used for overtaking. The middle lane is slightly slower, around 110 km/h, safe and steady. The right lane is the slowest, typically under 100 km/h or even lower, suitable for trucks, beginners, or those preparing to exit the highway. During peak traffic hours, speeds drop—like on weekends when congestion might reduce the left lane to 100 km/h, the middle to 90 km/h, and the right to 80 km/h. I emphasize maintaining a safe distance and not tailgating because large speed differences can easily lead to accidents. In rain or fog with poor visibility, speeds should be reduced by another 20%. The highway is designed with this speed hierarchy to reduce rear-end collision risks and ensure overall safety and smooth flow. As an experienced driver, I advise against hogging the left lane for long to avoid delaying overtaking. Everyone driving by the rules makes the journey smoother.

From a safety perspective, let me discuss speed classification on highways. On a three-lane expressway, the left lane allows speeds up to 120 km/h, but it's advisable to maintain around 115 km/h to keep a buffer space. The middle lane is ideal for steady cruising at 100-110 km/h. The right lane, suitable for slower vehicles and trucks, should maintain 90-100 km/h for safe merging. Traffic rules explicitly prohibit speeding and discourage driving too fast in the right lane to avoid dangerous lane changes. In adverse weather conditions like rain or snow, all speeds should be reduced by 10-20 km/h to prevent skidding. The lane design follows a principle of left-fast, middle-steady, right-slow to minimize accident risks, especially high-speed rear-end collisions. Traffic regulations encourage returning to the middle lane after overtaking in the left lane – I've personally observed fewer accidents with this practice. During daily driving, monitor your dashboard frequently and stay aware of surrounding traffic to ensure timely responses. Safety first, don't prioritize speed.

When I was learning to drive, my instructor explained the lane speeds very clearly. On a three-lane highway in the same direction, the left lane has the highest speed limit of 120 km/h and is mainly used for overtaking. The middle lane has a speed limit of 110 km/h and is suitable for normal driving. The right lane has a speed limit of 100 km/h and is the slow lane for trucks and slower vehicles. In reality, traffic conditions can affect speeds, such as during peak hours when speeds may drop by 10 km/h, so I need to pay attention to road signs and follow the flow of traffic. This tiered system on highways helps maintain traffic flow, reduce collision risks, and improve safety. After learning these rules, I feel more confident driving.

For daily commuting on the highway with three lanes, the common speed scenarios are as follows: the left lane is typically used for overtaking at 110 to 120 km/h, dropping to 100 km/h during peak hours. The middle lane maintains a steady speed of 100 to 110 km/h, which can be slightly higher when traffic is smooth. The right lane, serving as the slow lane, usually travels at 90 to 100 km/h, but can slow down to 80 km/h when congested. I adjust my position according to traffic conditions. During rainy or foggy weather, overall speeds should be reduced by 15 km/h—avoid being aggressive, as safe arrival is the priority.

Lane speeds vary based on road conditions. In clear and dry weather, the left lane is 120 km/h, middle lane 110 km/h, and right lane 100 km/h. In rainy or foggy conditions, speeds drop to possibly 100 km/h in the left lane, 90 km/h in the middle, and 80 km/h in the right to reduce the risk of losing control. During heavy traffic, the left lane slows down, the middle lane becomes chaotic, and the right lane gets congested. The highway design of faster left and slower right lanes helps prevent accidents. I adjust my driving to prevent fatigue from affecting speed and remain vigilant.
