Is Overtaking Only Allowed from the Left Side?

Is making a U-turn at a red light considered running a red light?

If the U-turn signal is red, making a U-turn is considered running a red light. According to the "Road Traffic Safety Law," this violation incurs: 6 penalty points and a fine of 200 yuan. If there is no U-turn signal, and the gap is marked with a dashed line, the U-turn is not affected by the traffic signal and does not require crossing the pedestrian crossing. If the gap is marked with a solid line, the U-turn must cross the pedestrian crossing and is subject to the traffic signal. Making a U-turn directly may result in being photographed or penalized by on-site traffic police. When making a U-turn that requires crossing the pedestrian crossing, yielding to pedestrians is necessary: Pedestrians walking on the right side of the road's crosswalk, not reaching the centerline of the road. Vehicles on the left side of the road should slow down and proceed only after ensuring safety. Pedestrians waiting outside the boundary line of the motorized and non-motorized lanes. If they have not entered the roadway, vehicles should slow down and proceed only after ensuring safety. If pedestrians cross the boundary line between the motorized and non-motorized lanes, vehicles failing to stop and yield is a violation and should be penalized. When pedestrians enter the motorized lane via the crosswalk, vehicles must slow down and proceed only after ensuring safety. Failure to stop and yield is a violation and should be penalized. Pedestrians waiting at the centerline of the road without entering the vehicle lane. Vehicles failing to stop and yield is a violation and should be penalized. Pedestrians crossing the centerline of the road into the vehicle lane. Vehicles failing to stop and yield is a violation and should be penalized. Roads with a median strip separating pedestrians. When pedestrians are waiting in the median area, vehicles must slow down and proceed only after ensuring safety. Permissible U-turn scenarios: Intersections with U-turn signs allow U-turns: If there is a clear U-turn sign at the intersection, a U-turn is permitted. If there is a U-turn signal, follow the signal's instructions. If there is no signal, proceed with the U-turn without obstructing other vehicles or pedestrians. Intersections without explicit "No U-turn" or "No Left Turn" signs allow U-turns: If there is no explicit prohibition, a U-turn is allowed. "No explicit prohibition" means the absence of "No U-turn," "No Left Turn," or solid centerlines. Yellow grid lines also permit U-turns: Yellow grid lines indicate no-stopping zones at intersections prone to congestion, important entrances, etc. Stopping on these lines (including waiting for traffic lights) is a violation. However, U-turns are permitted in yellow grid zones unless there is a center divider. Intersections with U-turn signals: If a U-turn signal is present, follow it—green means U-turn is allowed. Simultaneous "No Left Turn" and "U-turn Allowed" signs: U-turns are permitted, but left turns are prohibited. Note that "No U-turn" is not the same as "No Left Turn." Precautions when making a U-turn at intersections: Observe road markings. If the line is solid, U-turns are prohibited under any circumstances. Continue driving to find a suitable U-turn location. If there is a "No Left Turn" sign, even without a "No U-turn" sign, U-turns are not allowed at that intersection, as U-turns inherently involve a left turn. U-turns must be made from the innermost left-turn lane. If in the second left-turn lane, U-turns are not permitted at that intersection. Always yield to straight-moving vehicles. Only proceed with a U-turn if it does not interfere with straight-moving traffic; otherwise, you bear full responsibility for any accidents. Near intersection stop lines, lanes often have guiding arrows. The leftmost lane is not always a left-turn lane. If it has a straight arrow, U-turns are prohibited even without explicit "No U-turn" signs.

What is the function of the kingpin inclination angle?

The function of the kingpin inclination angle is: The kingpin inclination angle enables the vehicle's wheels to automatically return to the straight position after steering. The larger the inclination angle, the stronger the self-centering effect, but it makes steering the wheel more laborious and increases tire wear. It also facilitates easier steering. Below is relevant information: 1. The kingpin inclination angle refers to the acute angle formed by the projection of the vehicle's steering knuckle kingpin axis (or the connecting line between the upper and lower ball joint centers of an independent suspension) and the vertical line on a plane perpendicular to the vehicle's longitudinal symmetry plane. When viewing the tire from the front or rear of the vehicle, the kingpin axis tilts inward toward the vehicle body, and this angle is called the kingpin inclination angle. 2. When the wheel rotates around the kingpin, the lowest point of the wheel would theoretically sink below the road surface. However, in reality, the lower edge of the wheel cannot sink below the road surface. Instead, the steering wheel and the entire front part of the vehicle are lifted to a corresponding height. This creates an effect where the vehicle's own gravity helps the steering wheel return to its original straight position, making it easier to reset the steering wheel.

How to restart the Audi MMI system?

Here are the methods to restart the Audi MMI system: 1. Simultaneously press the SET-UP button and the button in the upper right corner of the large knob, then press the large knob to restart the system. 2. Visit an authorized 4S dealership to seek professional assistance. Below is relevant information about the MMI system: 1. Audi has developed a new operational control concept: the Multi Media Interface (MMI). The MMI ingeniously integrates the operation of all infotainment components within a single display and operating system. By streamlining the controller and implementing a unified logic, the MMI enables quick, convenient, and intuitive access to a wide range of functions and technologies. 2. The Audi MMI is Audi's innovative operational control concept: the Multi Media Interface (MMI). The MMI seamlessly combines the operation of all infotainment components in one display and operating system. Through a simplified controller and consistent operational logic, the MMI allows for rapid, easy, and intuitive use of numerous functions and technologies. Today, Audi drivers can access a broad array of information and entertainment systems, such as radio, CD player, TV, navigation system, and car phone. This combination of information and entertainment (infotainment) will become increasingly important in the future. However, the expanding range of functions and options inevitably conflicts with traditional in-car operational control structures.

What are the impacts of increasing wheel size?

Below are the effects of increasing wheel size on a car: 1. Larger wheels have greater load-bearing capacity: Wheels are typically made of steel to save costs, but larger wheels use aluminum alloy wheels, especially those made by forging processes. The load-bearing capacity of such wheels is five times that of ordinary steel wheels. 2. Larger wheels improve the vehicle's cornering performance: After wheel modification, the contact area increases, thereby enhancing the vehicle's stability during cornering and significantly improving cornering performance. 3. Larger wheels reduce ride comfort: Large-sized wheels can affect ride comfort. Generally, the outer diameter of the tire is a fixed value, meaning the larger the wheel, the thinner the tire's thickness. This results in poorer isolation of road noise, leading to increased cabin noise and affecting the vehicle's quietness. 4. Larger wheels may reduce car performance: Large-sized wheels can impact acceleration and braking performance. As the wheel size increases, the width also increases accordingly. Larger and wider wheels naturally weigh more, requiring more power to drive them, which affects acceleration performance. 5. Larger wheels increase fuel consumption: Large-sized wheels can raise fuel consumption. Larger wheels have an advantage in diameter, and the corresponding tread width is also larger. The benefit is that the increased contact area between the wheel and the road surface can enhance grip, helping to improve the vehicle's stability. However, the trade-off is increased friction, which can lead to higher fuel consumption to some extent.

How to Distinguish Automotive Fuel Lines?

Normally, the fuel inlet line is located above the fuel injector, while the return line is positioned below and branches out from the interior. Additionally, the fuel inlet line is generally larger in diameter than the return line, with the inlet line being the one connected to the fuel filter. Fuel lines are routed from the fuel tank to the engine compartment at the front of the vehicle, or in some models, they are externally mounted on the chassis, running through these recesses towards the engine. Some automakers design protective shields for these lines. More details are as follows: 1. The gasoline line connects the fuel pump to the engine's fuel injectors to supply fuel. There is also the power steering line, which provides hydraulic fluid to the steering gear to reduce steering resistance. The brake fluid line connects the brake master cylinder to the brake calipers; when the brake pedal is pressed, the master cylinder applies pressure through the brake fluid to the brake pads, which then clamp the brake rotor to slow or stop the vehicle. Essentially, these are the three main types of fluid lines. 2. Gasoline lines are divided into inlet and return lines. The line connected to the fuel filter and the fuel pump is the inlet line, while the thinner line returning from the fuel injector is the return line. The purpose of the return line: When the fuel pressure provided by the fuel pump exceeds 100 to 150 kPa, the overflow valve in the fuel filter's return line opens, allowing excess fuel to flow back to the fuel tank via the return line.

Can a Cloned Vehicle Be Transferred?

Cloned vehicles cannot be transferred. Cloned vehicles, commonly known as copycat cars, refer to vehicles that mimic the model and color of a genuine licensed vehicle, using counterfeit license plates with identical numbers on vehicles of the same model and color. Below are relevant details about cloned vehicles: Introduction to Cloned Vehicles: A cloned vehicle refers to a vehicle where criminals forge and illegally obtain the license plate number, model, and color of a genuine licensed vehicle, disguising smuggled, assembled, scrapped, or stolen vehicles with a 'legal' appearance. Cloned vehicles are also called 'copycat cars,' abbreviated as 'cloning.' Cloning involves labeling and has been strictly prohibited by the state. On August 20, 2012, the Ministry of Public Security clearly stipulated that vehicles confirmed to be cloned can have traffic violation records incurred during the cloning period revoked and may apply for new license plate numbers and vehicle registration certificates. Hazards of Cloned Vehicles: They disrupt public security control by authorities and create social instability. Cloned vehicles not only severely interfere with orderly road traffic but also increase the likelihood of traffic accidents. Moreover, as cloned vehicles lack legal procedures and insurance, drivers are more likely to flee after an accident, significantly complicating case resolution.
