Can You Shift Directly to P Gear When Parking an Automatic Transmission Car?

When parking an automatic transmission car, you should not shift directly to P gear, as this can cause damage to the vehicle. When turning off or idling for an extended period, it is necessary to shift into P gear because, once engaged, the parking pawl in the transmission will lock into the parking gear, securing the drivetrain. The correct method for parking an automatic transmission car is: After reaching the parking spot, press the brake pedal until the vehicle comes to a complete stop; shift the gear lever to N (neutral) without releasing the brake; engage the parking brake, then release the foot brake; wait for the car to stabilize, press the brake pedal again, shift into P gear, and finally lock the vehicle. An automatic transmission car eliminates the need for manual gear shifting by the driver, as the vehicle automatically selects the appropriate gear based on speed and traffic conditions. Automatic transmission gear positions include: P (Park) for parking, R (Reverse) for backing up, N (Neutral) for no gear engagement, D (Drive) for forward movement, M (Manual) for manual mode, L (Low) for low-speed driving, and S (Sport) for sport mode.

How to Lighten Car Window Tint?

To lighten car window tint, the only solution is to replace it with a lighter shade. Here are some precautions for car window tinting: 1. Full windshield coverage: Insist that the shop applies the film to the front and rear windshields without cutting, as cutting may compromise the anti-shatter properties and affect aesthetics. For vehicles with strong streamlined designs, the curvature of the front and rear windshields is greater, making it more challenging to apply the film smoothly with a heat gun, but skilled technicians can achieve a flat application. 2. Ensure a proper environment: Dust and gravel are the biggest enemies of tinting. Choose a decoration company with a closed workshop; most 4S shops meet this requirement. Weather is also crucial. On rainy or overcast days, higher humidity reduces static electricity and airborne particles, and both indoor and outdoor dust levels drop significantly. Such weather conditions help prevent impurities between the film and glass, ensuring a clean and attractive finish.

What to Do When Highways Are Closed Due to Fog?

Learn how to park safely: You should follow the vehicle in front and park behind it in order. If you are the last vehicle, you should place a triangular warning sign 150 meters behind your car, turn on all the vehicle's lights, and ensure all passengers quickly move outside the guardrail. Highway traffic control under severe weather conditions is divided into the following three levels: 1. Level 3 Control: When heavy rain, snowstorms, or thick fog reduce visibility to between 100 and 200 meters, Level 3 control is implemented, involving partial road closures and traffic interruptions lasting less than 3 hours. 2. Level 2 Control: When heavy rain, snowstorms, or thick fog reduce visibility to between 50 and 100 meters, making it unsafe for vehicles to proceed, Level 2 control is implemented, involving regional road closures and traffic interruptions lasting 3 to 6 hours. 3. Level 1 Control: When heavy rain, snowstorms, or thick fog reduce visibility to less than 50 meters, or when road surfaces become icy, making it unsafe for vehicles to proceed, Level 1 control is implemented, involving full highway closures and traffic interruptions lasting more than 6 hours.

Is It a Good Omen for a New Car to Have Minor Scratches and Dents?

Minor scratches and dents on a new car are not a good omen. Here are some precautions for using a new car: 1. Preheating the cold engine: Proper preheating helps form an "oil film" between engine components, thereby reducing wear and tear. 2. Timely gear shifting while driving: When driving a manual transmission car during the break-in period, shift gears promptly and appropriately to avoid incorrect behaviors such as high gear with low RPM or low gear with high RPM. Also, avoid using a single gear for an extended period. 3. Timely maintenance: Simply follow the manufacturer's recommendations in the vehicle manual. After reaching a certain mileage or time, promptly conduct vehicle inspections and maintenance, including oil and oil filter changes, along with a comprehensive check of the chassis system. 4. Avoid emergency braking: Emergency braking not only shocks the braking system during the break-in period but also increases the impact load on the vehicle's chassis and engine.

Can Subject 2 and Subject 3 be Applied for Simultaneously?

In a few regions, it is possible. The content and passing standards for the driver's license examination subjects are uniformly set nationwide, and the examination sequence follows Subject 1, Subject 2, Subject 3, and Subject 4 in order. Only after passing the previous subject can one proceed to the next. Currently, only a few regions allow Subject 2 and Subject 3 to be taken simultaneously, but in most areas, passing the previous subject is still required. Below are the relevant introductions to Subject 2 and Subject 3: Subject 2 and Subject 3 can be taken together. The new "Outline" states that each province should set relevant requirements for the training mileage of each permitted vehicle type based on actual conditions, but the minimum should not be less than 300 kilometers. The "hours" referred to in the new "Outline" are the basic hour requirements for each vehicle type. If additional examination content and items are needed, corresponding hours must be added. The new regulations also stipulate that "safe and civilized driving knowledge" teaching should be integrated with "road driving" teaching; "basic and field driving" and "road driving" can be trained alternately. This means that students can combine theoretical learning with actual hands-on practice, integrating Subject 2 and Subject 3. This approach not only saves time but also reduces the cost of the driving test.
