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, choose a reference point, maintain straight-line driving, correct the direction in time, and always be aware of various traffic conditions ahead to detect and handle them promptly. Adjusting the viewing distance ahead in time: Look far and near while holding the steering wheel straight. The driver should adjust the viewing distance ahead according to the speed. At higher speeds, look further ahead; at lower speeds, look appropriately closer, and use peripheral vision to monitor the surroundings. Steering smoothly: Operate the steering wheel by pulling with one hand and pushing with the other, ensuring smooth control. Keep both hands shoulder-width apart and avoid using excessive force.

As a novice driver who just got my license, I remember my instructor repeatedly emphasizing the importance of speed control. When driving straight, the speed should not be too slow, as it may cause traffic congestion or even rear-end collisions. Generally, the minimum speed limit on highways is 60 km/h, while on city roads there may not be a strict requirement, but it's recommended not to go below 30 km/h. At the same time, the speed should not be too fast—the safe upper limit varies by road: typically 50 or 60 km/h in urban areas, while on highways, it depends on posted signs like 120 or 130 km/h. During practice, I found that maintaining a moderate speed range not only feels smoother but also helps with observing road conditions in advance and avoiding sudden braking. For example, once during a nighttime highway drive, I was going too fast and almost missed reacting to a speed camera. After slowing down to around 80 km/h, I felt much more relaxed. In short, new drivers should pay close attention to roadside signs and keep speed limits in mind to drive safely and smoothly.

After years of driving, I've learned that maintaining a reasonable speed range is crucial for straight-line driving. The minimum speed on highways should not fall below 60 km/h to avoid obstructing traffic, while the maximum must adhere to limits—60 km/h on urban roads and 120 km/h on expressways. Experience shows that driving too slowly wastes fuel and frustrates others, whereas excessive speed heightens accident risks. I once witnessed a devastating crash caused by speeding and loss of control. Regularly check your vehicle's condition and heed real-time navigation alerts. Cultivating steady-speed habits (e.g., maintaining 70-90 km/h on national highways) optimizes fuel efficiency and ride comfort. Remember: traffic rules are written in blood—strict compliance is always wise.

As a family driver, I always prioritize passenger safety. When driving straight, the speed must not fall below the safety threshold, such as 40 km/h on highways (though most sections have a minimum of 60 km/h), to avoid rear-end collisions; nor should it exceed the maximum, like 60 km/h on urban roads or 130 km/h on highways. When driving with kids, I enforce stricter control: excessive speed increases motion sickness and risks, while driving too slowly prolongs the journey and causes anxiety. In good weather, I maintain a comfortable speed around 60 km/h, reducing it by 20% during rain. For instance, during a sudden fog encounter on the highway last time, I immediately slowed from 120 km/h to 80 km/h and passed through safely. Speed management is key to protecting everyone.

As a car enthusiast, I love discussing the extreme range of straight-line speeds. The minimum speed on highways is typically 60 km/h—too slow and you risk fines or slowing down overall traffic. The maximum speed must not exceed road signs, such as 130 km/h on highways, or you'll face repeated speeding tickets and costly repairs. While performance cars are powerful, they need restraint on public roads—I've driven 180 km/h on the track but stick to 90 km/h on daily roads for optimal engine efficiency and lower fuel consumption. Here's a tip: maintaining a speed between 70 and 100 km/h balances speed and mechanical wear. Always respect the rules when exploring speed limits to enjoy the thrill of driving.

I prioritize practical driving, maintaining a moderate speed. The minimum speed for straight-line driving should be at least 60 km/h on highways to avoid fines and traffic congestion; the maximum should not exceed limits such as 50 km/h in urban areas or 120 km/h on highways. From an economic perspective: fuel consumption spikes below 40 km/h, and above 100 km/h, increased wind resistance also leads to higher fuel usage. Through recorded observations, the optimal efficiency is around 80 km/h, which can save significant costs. On my last long-distance trip, maintaining a steady speed of 95 km/h saved me 20% in fuel costs compared to erratic acceleration. Before adjusting speed, check the regulations and monitor the dashboard to ensure both safety and economy.
