Why is it necessary to reach 60 km/h as soon as possible when entering the highway?

Because this prevents interference with vehicles traveling on the main lanes when merging into traffic. Here are the relevant details: 1. Highway speed limits: Highways must clearly indicate lane speed limits, with the maximum speed not exceeding 120 km/h and the minimum speed not falling below 60 km/h. 2. Precautions: After driving onto the acceleration lane from the ramp, promptly increase the vehicle speed to above 60 km/h to avoid affecting vehicles on the main lanes when merging. Carefully observe the traffic flow on the main lanes, choose the appropriate moment to merge, and avoid emergency braking or stopping in the acceleration lane.

After driving for so many years, I believe accelerating quickly to over 60 km/h when entering the highway is primarily for safety. If you dawdle at a sluggish speed of just 30 or 40 km/h, vehicles behind you traveling at 100 km/h won't have enough time to brake, making rear-end collisions far too likely. On highways, traffic moves fast, and if you act like an obstacle, you'll block the flow, causing a chain reaction. The acceleration lane is specifically designed for you to gradually build up speed—don't waste it. I remember witnessing an accident once because a car entered the highway too slowly, and a truck behind couldn't stop in time, crashing into it and blocking the entire entrance. So, reaching speeds above 60 km/h quickly reduces risks and protects both yourself and others. This habit also makes driving smoother and minimizes unnecessary friction on the road.

From a traffic perspective, accelerating to 60 km/h when entering the highway is to maintain smooth flow. The design of highway entrance ramps as acceleration lanes aims to allow vehicles to match the speed of the main traffic within a short distance, avoiding the creation of bottlenecks that could affect overall flow velocity. When speed differences are too large, the probability of accidents skyrockets and emissions also increase. I often remind myself to make good use of this zone—modern cars can easily reach 60 km/h within 100 meters, making it much less stressful to merge into traffic. Additionally, higher speeds actually improve fuel efficiency, as engines operate more efficiently at higher RPMs while also reducing pollution. In short, rapid acceleration is a crucial step in optimizing system performance.

When entering the highway, quickly accelerate to 60 mph mainly for convenience and to avoid causing congestion. If you drive too slowly, cars behind will honk or make sudden lane changes to overtake, which can startle you and waste time. Cars are designed for smooth acceleration, and high RPMs for a short period do not harm the engine but rather protect the system. Higher speeds improve tire grip, reducing the risk of skidding. I’m used to quickly merging into traffic—it feels free, efficient, and even saves a bit of fuel.
