D license refers to the Class D driver's license. The permitted vehicle type for a Class D license is a regular three-wheeled motorcycle, specifically motorcycles with an engine displacement exceeding 50ml or a maximum design speed exceeding 50km/h. To ride a motorcycle: If a vehicle owner wishes to operate a motorcycle, they must obtain a Class D driver's license. To acquire a Class D license, the applicant must pass both a written test and a practical driving test. Only those who pass will be issued the driver's license. Class D license examination content: The test subjects include three items: traffic regulations and related knowledge, field driving, and road driving (including safe and civilized driving).

Having driven for decades, the D gear is simply the forward gear of an automatic transmission. Once engaged, the car moves on its own without the need to press the clutch or shift gears like in a manual transmission. When I was younger, driving long distances would make my arms sore, but now the D gear makes driving much more relaxed. In city traffic jams, the automatic shifting is truly worry-free, as the car adjusts according to speed, ensuring safety and smoothness. However, remember not to engage the wrong gear—for instance, ensure you're in the P (Park) position before starting, and avoid staying in D gear for too long when parked on a slope; instead, shift to P gear to lock it more securely. Regular maintenance of the automatic transmission is essential, with oil changes every two years to prolong its lifespan. I've seen many novices cause issues due to improper operation, so gaining more knowledge about cars is always beneficial. With proper maintenance, there won't be any problems, making driving a true pleasure.

As a new car owner, I find the D (Drive) mode incredibly practical for daily driving. Shifting into D puts the car in forward motion—just press the accelerator after starting, and it handles gear changes automatically, eliminating hassle. In traffic jams, the car adjusts speed effortlessly, which is super convenient. My first car was an automatic, and after trying manual transmission, I truly appreciated D mode's intelligence. Just remember to ensure the gear is fully engaged—sometimes the car won't move if not properly shifted, but a quick check solves it. Modern cars may offer S (Sport) mode, but D remains the fundamental, beginner-friendly option. Maintenance is straightforward—just routine checks on cables and the computer system. At the end of the day, hassle-free driving is what matters most.

After years of repairing cars, common issues with the D gear are frequently encountered. It is the drive gear, and engaging it allows the car to move forward. Automatic transmissions rely on computer-controlled shifting, eliminating the hassle of manual operation. When shifting gears, it's essential to operate while the car is stationary to avoid damage. Many people mistakenly shift into the wrong gear, leading to transmission damage. It is advised not to directly shift into D when starting on a slope, as it can cause the car to roll back, posing a danger. Daily maintenance is straightforward—just change the oil and filter on time. Safety should always come first. Understanding the functions of each gear can reduce accidents, which is crucial.
