Is it mandatory to wear seat belts in the back seat?

It is mandatory to wear seat belts in the back seat. When driving a car, both front and rear passengers must wear seat belts. Whether you are the driver or a passenger, as long as you are in the vehicle, you must wear a seat belt. Both front and rear passengers must wear seat belts. When riding in a vehicle, whether you are seated in the front or the back, you need to wear a seat belt. Especially for drivers, it is essential to correctly fasten the seat belt in accordance with China's traffic laws and avoid any improper fastening behaviors. If seat belts are not worn correctly as required, collisions between vehicles can easily lead to traffic accidents, endangering lives. Passengers in the back seat must also wear seat belts properly; otherwise, they may be thrown forward during a collision, causing secondary injuries to front-seat occupants. Not wearing a seat belt will result in fines. According to China's "Road Traffic Safety Violation Points System," drivers who fail to wear seat belts will be penalized with a deduction of two points. Both drivers and passengers must use seat belts correctly as required by law. Rear-seat passengers must also wear seat belts; failure to do so may result in fines, with specific penalties varying by city and local regulations. Not wearing a seat belt poses many dangers. Drivers who do not wear seat belts are at risk of hitting the windshield or even being ejected from the vehicle during a collision. Front-seat passengers who do not wear seat belts may suffer injuries from deploying airbags. Rear-seat passengers must also wear seat belts; otherwise, in the event of an accident, they may sustain severe head injuries.

How to Cancel a Driving Practice Appointment?

Call the driving school directly to cancel and also inform the coach that you won't be attending. Generally, it's best to cancel at least half a day in advance; otherwise, the cancellation may not be processed, and it will still count as if you attended, affecting your practice session count. Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment, referred to as the field driving skill test. For small cars (C1/C2), the test items include five mandatory components: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves (commonly known as S-turns). If any of the following behaviors occur during the test, the current subject test will be terminated, the score will be invalidated, and a new test appointment will be required: 1. Answering phone calls or checking pagers; 2. Disrupting the order within the test area; 3. Making loud noises or disobeying the management of the staff.

How to Brake Slowly and Steadily?

To brake slowly and steadily, different techniques should be applied according to different situations. Below are introductions from four aspects: smooth braking, braking on curves, braking to prevent rear-end collisions when following a car, and braking on slopes. Smooth Braking Techniques: Many beginners struggle with mastering the timing and force of braking, often resulting in harsh braking. When the braking distance is sufficient, press the brake pedal slowly and continuously to decelerate evenly. As the vehicle is about to stop, gradually release the brake pedal until it is fully lifted when the car comes to a complete stop. After parking, placing a temporary parking sign can provide additional peace of mind. Braking Techniques on Curves: When approaching a curve, brake before entering the curve, decelerate slowly to enter the curve, and then accelerate out of it. While braking on a curve, steer the wheel to adjust the car's posture according to the curve's arc. Avoid slamming on the brakes, especially if you are in the outer lane, to prevent losing control of the vehicle. Braking Techniques to Prevent Rear-End Collisions When Following a Car: The main purpose of braking when following another car is to maintain a safe distance from the vehicle in front. This means using the brake to keep a speed that is roughly the same as the car ahead. Therefore, the key technique is to press the brake pedal gently and maintain braking force. If you notice the car in front braking, move your foot to the brake pedal in advance to prepare for sudden braking by the leading car. For added safety, consider installing anti-collision strips on your vehicle. Braking Techniques on Slopes: Braking on an uphill slope is similar to braking on flat roads, but due to the deceleration effect caused by the vehicle's weight, the braking force required is slightly less than on flat roads. Brake gently on an uphill slope, even more gently than on flat roads, but release the brake pedal faster than you would on a flat road to ensure the speed does not drop excessively.
