At an intersection with standard three-color traffic lights, you may turn left on a green light, but you must yield to oncoming straight-moving vehicles first. When encountering lane arrows, if the straight arrow is green but the left-turn arrow is red, you cannot turn left, but you may enter the left-turn waiting area. When the left arrow turns green, vehicles in that lane can proceed with the left turn. The relevant requirements for turning are as follows: 1. Motor vehicle and non-motor vehicle traffic signals indicate: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians that have been given the right of way. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, vehicles are prohibited from proceeding. 2. Lane signals indicate: When the green arrow light is on, vehicles in that lane are permitted to proceed in the indicated direction. When the red cross light or arrow light is on, vehicles in that lane are prohibited from proceeding.

When the straight-through light turns green, you cannot directly make a left turn. Nowadays, many intersections have dedicated left-turn arrow signals. If that signal is red or not lit, even if the straight-through light is green, you must wait patiently. Last time I was driving, I encountered this situation—the left-turn light suddenly turned red, and I quickly stopped behind the line. However, the car next to me forced a left turn and was immediately pulled over by traffic police, who issued a ticket. Actually, this design makes sense: left-turning vehicles intersect with oncoming straight-moving traffic, making side collisions particularly likely. I recommend that beginners pay close attention to the overhead signals at intersections: arrow signal groups control directional turns, while full-circle signals control straight-through movement. Remember, only a green left-turn arrow or a green light with an arrow allows a safe left turn. If you encounter a circular green light without a left-turn arrow, you can usually only go straight or turn right—never risk cutting into the lane.

What causes the noise from the aluminum seat of the rear shock absorber in Volkswagen?

Here are the reasons for the noise from the shock absorber: 1. Damaged shock absorber: When the vehicle's shock absorber is damaged, the coordination between its components becomes problematic, causing a rattling noise when working on bumpy roads. 2. Damaged shock absorber top mount: The front shock absorber top mount of a car is made of rubber material, primarily serving to assist the shock absorber and spring in providing cushioning and shock absorption. When the top mount is damaged due to excessive wear, it not only produces noise during operation but also generates noise when turning the steering wheel while stationary, even if the shock absorber is not engaged.

What is the purpose of a car's three-way catalytic converter?

It converts harmful gases such as CO, HC, and NOx emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Below is an introduction to the three-way catalytic converter: Introduction: The three-way catalytic converter refers to the process of transforming harmful gases like CO, HC, and NOx from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Three-way catalytic converter: It primarily uses a three-way catalytic converter, whose core component is a porous ceramic material installed in a specially designed exhaust pipe. It is called a "carrier" because it does not participate in the catalytic reaction itself but is coated with precious metals such as platinum, rhodium, palladium, and rare earth coatings. It is the most important external purification device installed in a vehicle's exhaust system.
