What are the speed requirements for straight-line driving in an automatic transmission vehicle?
2 Answers
The assessment requirements for straight-line driving require the driver to start smoothly, control the speed properly, hold the steering wheel correctly, and use the steering wheel to adjust the driving direction appropriately. The new regulations add the requirement that the left and right deviation distances should not exceed 50 cm each. It is important to note that the steering wheel can be adjusted during straight-line driving, but the adjustment range should not exceed 5 degrees. For more details, please see the following: 1. Regarding the visibility issue in straight-line driving: Adhere to the principle of "looking far while taking care of the near." You should look far ahead while also paying attention to the nearby and rear conditions of the vehicle. Since the speed in the third subject is fast, looking far ahead allows you to detect situations early and react in advance. At the same time, the vehicle is more likely to drive straight. 2. Regarding the speed issue in straight-line driving: The straight-line driving section in each test site starts at a fixed section of the road. When the vehicle approaches the straight-line driving section, you can straighten the vehicle body in advance, adjust the steering wheel properly, ensure the vehicle is straight and the direction is correct, and stabilize the speed.
When driving an automatic car in a straight line, speed mainly depends on traffic rules, not the transmission. The speed limit on highways is 120 kilometers per hour, while in urban areas it's generally below 60 km/h, and rural roads may allow up to 80 km/h. The key is to follow road signs—don’t speed, as it leads to fines, penalty points, and danger. On straight roads, avoid slamming the accelerator; the car shifts gears automatically in D mode, so just accelerate smoothly. I always watch for speed limit signs when driving—safety first. On straight highway sections, maintaining a steady speed saves fuel and ensures comfort. In fog or rain, reduce speed by half to avoid braking issues. In short, adjust speed flexibly—slow down when necessary and don’t push it. Regularly check tire wear, as unstable tire pressure can also affect speed control. This is crucial.
