Why is it necessary to shift gears?
1 Answers
The reason for shifting gears while driving is to frequently change gears according to actual conditions (except on highways) to save fuel and improve engine efficiency. On highways, when quickly accelerating to speeds above 60 km/h, the 5th gear is generally used with minimal shifting required. However, gear shifting becomes necessary when road conditions are poor. When driving on urban roads, rural roads, or mountain paths, gear shifting should be more frequent to select appropriate speeds based on road conditions. Below are precautions for driving on highways: 1. Drive in the designated lane: Highways have clearly marked lanes for large vehicles, small vehicles, etc. After overtaking, promptly return to your original lane and avoid occupying other lanes for extended periods. Additionally, emergency lanes should not be occupied without special reasons. 2. Maintain safe speeds and avoid speeding: The dangers of speeding are well-known, as it can lead to irreversible consequences both on local roads and highways. 3. Maintain safe following distances: Under normal conditions with dry roads and good braking, the following distance (in meters) should not be less than the speed (in km/h). For example, maintain at least 80m at 80 km/h and 100m at 100 km/h. Always pay attention to roadside distance markers. In rainy, foggy, snowy, or wet road conditions, the following distance should be doubled. 4. Observe traffic signs: Always pay attention to roadside and overhead signs and markings, and drive appropriately to the right to avoid crossing the right lane divider, allowing sufficient lateral distance for overtaking vehicles. 5. Do not occupy emergency lanes unnecessarily: Traffic accidents are inevitable on highways. If other vehicles cause lane blockages due to accidents, avoid occupying emergency lanes arbitrarily, as this may hinder rescue operations. 6. Avoid fatigue driving and take timely breaks: Fatigue driving is extremely dangerous on highways. When fatigued, reaction times decrease, making it difficult to respond correctly to emergencies.
