How to Determine the Minimum Speed Limit?

[OLillian]

Here is an introduction on how to determine the minimum speed limit: 1. Two lanes in the same direction: If there are two lanes in the same direction, the minimum speed limit for the left lane is 100 kilometers per hour. 2. Three or more lanes in the same direction: If there are three or more lanes in the same direction, the minimum speed limit for the leftmost lane is 110 kilometers per hour. 3. Middle lane: The minimum speed limit for the middle lane is 90 kilometers per hour. 4. Road speed limit signs: If the speed indicated on road speed limit signs differs from the above lane speed regulations, drivers should follow the speed indicated on the road speed limit signs.

Having driven for many years, I'm accustomed to watching the speedometer in the center of the dashboard for the lowest speed. Typically, the needle or digital display starts climbing from 0 km/h, often dropping to around 10 km/h in urban traffic jams, when I can clearly see the dashboard reading. At idle, the speed is lowest, between 3-5 km/h, noticeable by the engine sound becoming quieter. When driving at low speeds to save fuel, the needle stays steady in the 15-20 km/h range. If the dashboard glass gets dirty, I wipe it with a soft cloth to ensure clear visibility. Normally in the city, I maintain low speeds to avoid high fuel consumption, especially paying attention to skid prevention on rainy or snowy days. Regularly checking wheel sensors prevents data errors, and in older cars, a shaky needle reminds me to lubricate the components.

I always enjoy playing with the car's electronic systems, using the digital display on the central control screen to check the minimum speed. In the cruise control settings, I press the button to set the minimum speed, starting at 30km/h. The smart HUD projects the real-time digital speed onto the windshield. After connecting an OBD2 device, mobile apps like Torque can record all speed data, including changes as small as 1km/h. Electric cars like Tesla allow easy adjustments via touchscreen sliders. When upgrading the audio system, I added a speed alert that beeps at low frequencies. Driving at low speeds on icy roads is safer and more energy-efficient. How accurate is Bluetooth navigation compared to real-time GPS speed measurements in millimeter-level precision tests?

I prioritize safety while driving, glancing at the dashboard at low speeds to ensure staying below 5km/h to avoid obstacles. When starting, I take it slow and watch the dashboard numbers climb from zero. I reduce speed during turns, keeping it under 15km/h for stability. Before speed bumps, I stop to observe, ensuring the lowest speed reading. If the dashboard lighting is dim, I activate the backlight for better visibility. Tire wear can affect speed perception, so I recommend monthly tire pressure checks. During nighttime city driving, don't just focus on the speedometer—paying attention to the surroundings is crucial to prevent rear-end collisions.

Common car maintenance involves checking the minimum speed using a diagnostic tool to scan the OBD port. When a sensor fails, the dashboard may abnormally display low-speed ranges. I clean the wheel speed sensors to remove dust and ensure accuracy. For manual transmission cars, maintain a steady speed and observe if the needle stabilizes within the 20 km/h range. Speedometer errors in older cars can be calibrated by comparing with GPS. After installing new parts, test idle speed at 0 km/h for detection. Preheating before cold starts in winter can prevent false readings. Minimum speed accuracy is higher when oil temperature is normal. Regularly replacing the battery avoids voltage fluctuations affecting the display.

When I was a beginner on the road, I simply watched the numbers on the dashboard change to monitor the minimum speed. In city traffic jams, it often got stuck in the 10-15 km/h range, with the LCD screen being clear and readable. Before entering the parking garage, I would slow down to 5 km/h and glide slowly while checking the dashboard for confirmation. On the highway, I maintained a minimum of 60 km/h but usually didn’t pay attention to the upper and lower limits. A slight vibration in the car body served as a low-speed reminder. On rainy days when the wipers blurred, I promptly cleaned the windshield. Setting up a voice prompt for the low-speed warning system proved much more useful. A simple comparison with a mobile app’s real-time speed updates made it easier for beginners to develop good habits.
