What is the minimum and maximum speed for straight-line driving?

Straight-line driving speed should be between 30 km/h and 40 km/h, meaning it should not be lower than 30 km/h or higher than 40 km/h. Below are some relevant techniques for straight-line driving: Selecting a reference point: When driving straight, the driver should look ahead and pay attention to both sides, must choose a reference point to maintain straight-line driving, promptly correct the direction, and always be aware of various traffic conditions ahead to detect and handle situations in a timely manner. Adjusting the viewing distance promptly: Look far and near while holding the steering wheel straight. The driver should adjust the viewing distance according to the speed changes. At higher speeds, look further ahead; at lower speeds, look relatively closer, and use peripheral vision to monitor the surroundings of the vehicle. Steering smoothly: Operate the steering wheel by pulling with one hand and pushing with the other, keeping both hands steady. Keep your hands shoulder-width apart and avoid applying too much force.
When driving on the highway, I pay special attention to the speed. The minimum speed for straight-line driving generally should not be lower than 60 kilometers per hour, otherwise it's easy to be rear-ended by vehicles behind and it's also illegal; the maximum speed should not exceed 120 kilometers per hour, as exceeding the speed limit caught by cameras will result in penalty points and fines. Remember, in special sections like tunnels or during rainy days, the speed limit drops to around 80. I usually drive at about 100, which feels safest—not too slow to be honked at, nor too fast to lose control.
Back when I was taking the driving test, the straight-line driving requirement was really strict. The speed had to be maintained between 30 and 40 km/h. The instructor always warned that going below 30 would result in an automatic fail, while exceeding 40 could easily cause the car to veer off course. During my test, I kept a close eye on the dashboard to maintain around 35 km/h and lightly held the steering wheel with both hands to pass successfully. On regular roads, there's no strict minimum speed limit, but if you drive below 20 km/h, you should turn on the hazard lights to alert vehicles behind you—otherwise, it can be quite dangerous.
