Whether you can make a U-turn in a left-turn lane mainly depends on the signs at the intersection. Situations where U-turns are allowed: 1. When driving in a left-turn lane without a U-turn signal and not having passed the stop line, and the intersection has dashed lines, a U-turn is allowed regardless of the red light, but you must yield to other vehicles; 2. When driving in a left-turn lane and not having passed the stop line, and the central barrier at the intersection has a U-turn passage, a U-turn is allowed regardless of the red light, but you must yield to other vehicles; 3. When driving in a left-turn lane without a U-turn signal, and the intersection has no dashed lines or gaps in the guardrail, follow the traffic light ahead—U-turns are allowed on green after crossing the stop line and pedestrian crossing; 4. When driving in a left-turn lane with a U-turn signal at the intersection, and the intersection has no dashed lines or gaps in the guardrail, follow the U-turn signal—U-turns are allowed on green after crossing the stop line and pedestrian crossing. Situations where U-turns are not allowed: 1. When driving in a left-turn lane and not having passed the stop line, and the intersection has dashed lines, but there is a U-turn signal showing red, U-turns are prohibited; 2. When driving in a left-turn lane without a U-turn signal, and the intersection has no dashed lines or gaps in the guardrail, follow the traffic light ahead—U-turns are prohibited on red; 3. At intersections with a 'No Left Turn' sign, neither left turns nor U-turns are allowed.

In my twenty years of driving experience, this issue is quite common. I remember at intersections in old urban areas, making a U-turn in the left-turn lane depends on road signs and traffic signals. If there are no prohibitory signs and the road width permits, theoretically, a U-turn is allowed. However, safety must be ensured, such as avoiding peak traffic, checking mirrors, and preventing collisions with straight-moving vehicles. I've been fined a few times in Guangzhou for overlooking no-U-turn signs on small roads. Rules vary by location; intersections in big cities often have restrictions, while suburban areas might be more lenient. Develop a habit: always scan for surrounding signs before maneuvering, don't rush into turns—preventing accidents is more important than saving time. It's advisable to carry a traffic handbook for reference, as beginners are more prone to oversight.

What Does It Mean When the ABS Light on the Dashboard Is On?

The ABS light on the dashboard indicates a malfunction in the vehicle's Anti-lock Braking System. During emergency braking, if the wheels lock up, the vehicle may lose control and skid, making it difficult for the driver to slow down or adjust the vehicle's trajectory, which poses significant safety risks. Common ABS Issues and Solutions: ABS Warning Light Stays On: Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding wheel speed signal. This prevents the ABS computer from determining the wheel speed or calculating the wheel slip rate, thus failing to issue commands to adjust braking. Solution: Clean the dirt off the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Loose connections in the system wiring or poor contact in the ABS relay can lead to signal issues and system failure. The most common issue is a loose connection in the wheel speed sensor wiring, which will also show up as a wheel speed sensor signal error in the ABS computer's fault memory. Solution: Check the wiring connections and reconnect any loose parts. ABS Warning Light Intermittently Illuminates but Turns Off During Acceleration: Cause: When multiple vehicle electrical components are in use, the battery voltage may drop below 10.5V. As the engine speed increases and the voltage rises, the ABS light turns off. This could also be due to insufficient power supply voltage to the ABS system, such as poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact).

Will the Car Lock Itself with the Key Inside?

For models equipped solely with "keyless entry" functionality, the vehicle can detect the presence of the key inside and will not automatically lock. Below is relevant information: 1. Many vehicles feature an automatic locking function when doors are closed. For instance, even entry-level BYD models have a 30-second auto-lock feature, which can sometimes be inconvenient. These functions can be enabled or disabled via the diagnostic computer at authorized 4S service centers. 2. For models without "keyless entry" functionality, if the vehicle is turned off and the doors are closed without the key, both the doors and trunk will automatically lock after a few minutes.

Is it necessary to file a registration for changing vehicle rims?

Modifying rims and altering tire sizes may result in failure to pass annual inspections and complete vehicle transfers. Therefore, changing rims also requires filing for registration. Before making modifications, it is advisable to consult the local vehicle management office for detailed information. Below are the specifics: 1. According to the "Motor Vehicle Registration Regulations," any changes to the body color, model, performance, purpose, or structure of a licensed motor vehicle, including replacing the frame, body, or engine, must be reported to the vehicle management office for registration of modifications. 2. If the replacement rims are of the same size, they may generally pass the annual inspection, provided the appearance does not change significantly, unless local policies are particularly strict. Upgrading to a high-quality set of rims can improve heat dissipation and reduce vehicle weight, offering significant visual impact both statically and dynamically, while also enhancing the vehicle's handling performance. Prior to modification, consulting the vehicle management office is recommended to avoid potential issues during annual inspections, which could lead to orders to revert to the original setup.

How to Affix the Compulsory Traffic Insurance Sticker?

New vehicles should affix the compulsory traffic insurance sticker in the upper right corner of the windshield where it does not obstruct the view. The "Regulations on Compulsory Traffic Accident Liability Insurance for Motor Vehicles" clearly stipulate: The compulsory traffic insurance sticker should be affixed to the upper right corner of the front windshield in the driver's compartment; if there is no driver's compartment, it should be carried at all times. Below are the precautions for affixing the compulsory traffic insurance sticker: 1. The compulsory traffic insurance sticker can be directly affixed to the upper right corner of the front windshield by peeling off the sticker and applying it. However, when directly affixing the sticker to the windshield, it can be difficult to remove when expired or when replacing the windshield. 2. You can use a static cling sticker to affix the compulsory traffic insurance sticker. Peel the compulsory traffic insurance sticker from its backing paper, attach it to the static cling sticker, then remove the protective paper. After affixing, peel off the static cling sticker and apply it to the upper right corner of the front windshield.

Why Does a Sedan Make a Clunking Sound When Driving on Uneven Roads?

The reasons why a sedan makes a clunking sound when driving on uneven roads: 1. Loose Ball Joint of the Control Arm: If the ball joint of the lower control arm is loose with excessive clearance, it will produce abnormal noises when the car bumps. 2. Aging Plastic Components: Loose or excessively gapped stabilizer bar bushings. 3. Damaged Shock Absorber: A damaged shock absorber can also cause abnormal noises when the car passes over uneven roads. Although shock absorbers have a relatively long service life, they are still a vulnerable part of the car; if the driving environment is poor or the car is frequently driven aggressively, damage or oil leakage is inevitable. 4. Aging Buffer Rubber: The connection points between the shock absorber and the car body are cushioned with rubber. Rubber products will harden and age after prolonged use; when hardened rubber is squeezed, it produces a clunking sound.
