After entering the highway acceleration lane, how quickly should the speed be increased?

After driving a motor vehicle from the ramp into the acceleration lane, turn on the left turn signal and increase the speed to above 60 km/h as soon as possible to avoid affecting vehicles traveling on the main lane when merging into traffic. Carefully observe the traffic conditions on the driving lane and choose the right moment to enter the driving lane. Do not perform emergency braking or stop in the acceleration lane. Below are some precautions for highway driving: Speed control: On highways, the speed is generally between 80~100 km/h, with 90 km/h recommended as a constant speed. When exiting the highway and entering the ramp, apply the brakes twice—first when seeing the 500-meter exit sign, reducing speed to 60~70 km/h, and second when entering the ramp, reducing speed to 40 km/h. Driving and lane changing: Generally, lane changes and merging are not required.
After driving on the highway for a long time, I've concluded that the speed in the acceleration lane should be increased to match the main road as quickly as possible, typically around 80 to 100 kilometers per hour. Why? Because vehicles on the main road are moving fast, and if you're too slow, the car behind might not have enough time to avoid a rear-end collision, which can be really dangerous. I usually check the rearview mirror before entering the acceleration lane to observe the traffic flow and choose the right moment to accelerate smoothly. During smooth traffic or on roads with higher speed limits, aiming for 120 kilometers is reasonable, but don't exceed the legal speed limit. The key is to keep the process steady—avoid stomping on the gas pedal and causing the car to jerk, ensuring both yourself and other drivers can merge safely. In bad weather conditions like heavy rain or fog, you can slow down a bit, but still need to speed up to match the flow of the main road.
When driving, the acceleration lane is a great place to speed up! You need to quickly reach 100 or 120 km/h so that merging into the main road won't cause trouble for vehicles behind you, forcing them to brake suddenly. Different cars feel different—small-displacement sedans require deeper throttle input to quickly reach the target speed, while SUVs or vans might be a bit slower, but the key is not to hesitate. Blending into the traffic flow is crucial; the main road moves fast, and if you're even slightly slow, you might get honked at or flashed with headlights as a warning. I’ve experienced this a few times—when driving a friend’s electric car, the acceleration was super quick, zooming right up to speed, making merging with traffic incredibly smooth. So, it’s best to choose a speed range between 60 to 120 km/h based on your car’s performance and traffic conditions—speeding up early means staying safe early.
