The solution for a malfunctioning reversing radar is: Check whether the power cord of the main unit is properly connected and if there is any current, and see if the radar main unit wire is loose. If neither of these is the issue, then the reversing radar module or the buzzer is likely damaged and needs to be replaced at a 4S shop or repair shop. The reversing radar will not respond in the following situations: 1. Obstacles that are too low: Obstacles lower than 10 to 15 centimeters below the center of the probe will be ignored by the probe; 2. Obstacles that are too thin: The ultrasonic signals emitted by the radar probe are relatively narrow, resulting in significant blind spots when detecting very thin obstacles; 3. Ditches and bumps: The radar is designed to detect obstacles, so it will not react to ditches or bumps behind the vehicle.

What is the standard for hill start?

The requirements for hill start can generally be divided into two situations. Below is a detailed introduction to the requirements for hill start in cars: General situation: Failing to use or incorrectly using the turn signal when entering the designated area results in a deduction of 10 points. If the front bumper of the car does not stop on the pole line after the vehicle stops, and the deviation is not more than 50cm, a deduction of 10 points is applied. After the vehicle stops, if the body is 30cm-50cm away from the road edge line, a deduction of 10 points is applied. If the vehicle rolls back less than 30cm during start, a deduction of 10 points is applied. Failing to use or incorrectly using the turn signal when starting or leaving the designated area results in a deduction of 10 points. Special situation: If the vehicle rides or presses the solid center line or edge line of the lane during driving, a deduction of 100 points is applied. After the vehicle stops, if the body is more than 50cm away from the road edge line, a deduction of 100 points is applied. If the parking brake is not tightened after stopping, a deduction of 10 points is applied. If the start time exceeds 30 seconds, a deduction of 100 points is applied.

How many points are deducted for changing lanes without signaling?

Changing lanes without using the turn signal will result in a deduction of three points. Failing to activate the turn signal when changing lanes can create safety hazards for vehicles behind, as the lack of signal increases the risk of rear-end collisions. Here is relevant information: Surveillance: Forgetting to use the turn signal can be captured by surveillance cameras. Traffic management authorities have increasingly sophisticated methods for monitoring road conditions, and even minor infractions like not wearing a seatbelt or using a phone while driving can be recorded. Developing good habits: It is essential to cultivate the habit of using turn signals. Nowadays, most vehicles are equipped with dash cams, which record incidents like rear-end collisions or other accidents. If an accident occurs due to the driver's failure to signal, the driver is highly likely to bear primary or full responsibility for the accident.

What is the Difference Between Lane Changing and Overtaking?

Lane changing refers to the practice of a vehicle moving from one lane to another when both vehicles are originally traveling in the same lane. Overtaking refers to a vehicle moving to the side of another vehicle. Below are relevant details: Precautions for overtaking: Downshift and accelerate early when overtaking; observe carefully and make accurate judgments; avoid overtaking when the vehicle ahead is also overtaking; if unexpected situations are detected, stay calm, slow down as soon as possible, and stop overtaking; avoid overtaking when there is an oncoming vehicle ahead. Precautions for lane changing: When changing lanes, steer quickly but not too sharply, and merge into the adjacent lane along a curved path. Once the vehicle enters the adjacent lane, immediately straighten the steering wheel to ensure the vehicle stays centered in the lane and drives straight. When a vehicle needs to change lanes, the driver must first observe the traffic conditions behind, beside, and in the intended lane through the interior and exterior rearview mirrors and windows.

Should You Use Turn Signals When Changing Lanes?

Changing lanes requires the use of turn signals to inform other vehicles of your intention to change lanes. Below are relevant details: Regulations: Article 57 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states that motor vehicles should activate the left turn signal in advance when turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn. Similarly, the right turn signal should be activated in advance when turning right, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside. Lane Change Precautions: When merging into the main lane from an acceleration lane, observe the traffic in the main lane and merge behind normally moving vehicles when traffic is sparse. If a vehicle is closely following, control your speed and merge only after all vehicles have passed—avoid abruptly cutting in. Always use turn signals in advance when changing lanes.

Do I still need to display insurance stickers on my car after purchasing auto insurance?

After purchasing auto insurance, you no longer need to display the insurance sticker on your car. However, the compulsory traffic insurance sticker and annual inspection sticker still need to be displayed. The compulsory traffic insurance sticker can be obtained by purchasing compulsory traffic insurance, which is a mandatory insurance required by the state for all vehicles. Once a car is registered with the vehicle management office, it must display the annual inspection sticker. Vehicle annual inspection refers to the mandatory testing required for all vehicles that have obtained official license plates and registration certificates. It is equivalent to an annual physical examination for vehicles based on the safety technical requirements for motor vehicle operation. Vehicle annual inspections help promptly eliminate potential safety hazards, encourage better vehicle maintenance, and reduce the occurrence of traffic accidents.
