How fast do you drive on the highway?

[VanAdriana]

There is no unified regulation, as speed limits vary on different highways. Even on the same highway, speed limits may differ in different sections. Starting from the left lane, the general speed limits 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. Here are other regulations: 1. Drive according to the rules: The national speed limit does not exceed 120 km/h, but highways may set special speed limits based on specific conditions, such as posting speed limit signs of 110, 100, or 90 km/h. In such cases, drivers must adhere to the posted speed limits. 2. Drive according to the lane speed requirements: On highways, the maximum speed for small passenger vehicles must not exceed 120 km/h, for other motor vehicles 100 km/h, and for motorcycles 80 km/h. If there are two lanes in the same direction, the minimum speed for the left lane is 100 km/h; if there are three or more lanes, the minimum speed for the leftmost lane is 110 km/h, and for the middle lane 90 km/h. If the speed limit indicated by road signs differs from the above lane speed regulations, drivers must follow the speed limit indicated by the road signs.

We've been driving for over a decade, and maintaining a speed between 110 to 120 km/h on highways is generally the most stable. This range ensures you're not speeding excessively while effectively utilizing road resources. The key is to consider road conditions and weather – on clear days with light traffic, you can go slightly faster, but during rain or fog, I definitely slow down to around 90 km/h. Exceeding 120 km/h is actually quite dangerous; not only does the braking distance double, but the strain on tires and suspension also increases significantly. Additionally, when approaching tunnels or construction zones, I always reduce speed to around 80 km/h in advance – safety first. Remember not to drive too slowly either, as speeds below 60 km/h might actually cause rear-end collisions. Maintaining a reasonable speed range is the safest approach.

As someone who frequently travels long distances for business, I've found that speed on the highway needs to be adjusted flexibly. My habit is to drive at around 115 km/h in the leftmost lane, which generally keeps up with the traffic flow. But when encountering slow-moving trucks, I briefly accelerate to about 125 km/h to overtake them quickly and avoid driving side by side for too long. In reality, speed should depend on your driving habits and the condition of your vehicle. When driving a small-displacement car, I don't dare to accelerate and overtake casually, whereas with a powerful SUV, I can be more stable. Additionally, it's essential to pay attention to the average speed checks indicated by the navigation—suddenly braking to reduce speed is too dangerous. For long-distance driving, it's best to take a break at a service area every two hours to relax.

I believe the most important things when driving on highways are smoothness and safety. On roads with a speed limit of 120, I usually set the cruise control to 115, which avoids speeding tickets and maintains fuel efficiency. Nowadays, new cars come with HUD displays, allowing you to monitor real-time speed at all times. Be extra careful as speed limits vary across provinces; I always readjust my speed when crossing provincial borders. There's really no need to compete with others over speed—I once saw someone speeding at 150, only to rear-end another car not far ahead. Always maintain a safe following distance of at least three seconds; at high speeds, braking becomes much harder. In summer, also be cautious of high road temperatures that can lead to tire blowouts.

I pay special attention to how vehicle conditions affect speed. When the AC is on, power output decreases slightly, so I leave extra margin when overtaking. With a full load, braking distance increases, so I proactively reduce speed by 10%. During the break-in period of a new car, I never exceed 100 km/h, while for older vehicles on highways, I feel safest keeping it around 90 km/h. With electric vehicles, I'm particularly mindful of battery levels - power consumption spikes dramatically above 110 km/h. Even performance cars need to slow down in strong crosswinds, as sudden steering instability can be dangerous. Truthfully, appropriate speed depends entirely on vehicle condition - it's not just about making time. Regular checks of tire pressure and brake pads are crucial.

I pay special attention to comfort and fuel efficiency when driving. Through testing, I've found that my car operates most efficiently at speeds between 95 to 100 km/h, where it achieves lower fuel consumption and reduced noise levels, making long-distance driving less tiring. Exceeding 110 km/h significantly increases wind noise, and the engine sound becomes more aggressive, which becomes particularly irritating over time. However, driving too slowly isn't ideal either; below 90 km/h, the car feels underpowered, making overtaking difficult. I usually choose the middle lane and maintain a speed of around 100 km/h, ensuring I don't obstruct faster vehicles nor impede slower ones. Using ACC (Adaptive Cruise Control) makes driving much more effortless, as it automatically adjusts speed based on the vehicle ahead. Another useful tip is to avoid driving during peak morning and evening hours when traffic is lighter, allowing for more consistent speeds.
