The method for observing four traffic lights is as follows: 1. Red light: Vehicles (including bicycles, motorcycles, and electric vehicles) cannot go straight or turn left but can turn right. 2. Green light: Vehicles can go straight, turn left, or turn right (pay special attention to the directional arrows on the traffic lights). 3. Directional light is green: Vehicles can proceed in the direction indicated by the arrow on the traffic light. 4. Directional light is red: Vehicles cannot proceed in the direction indicated by the arrow on the traffic light. Additional information: 1. Traffic lights: Also known as traffic signal lights, they are light signals that change alternately at specified times, usually installed at intersections or other special locations to assign the right of way to drivers and pedestrians, regulating their movement and turns as traffic control facilities. 2. Traffic light alternation pattern: The general sequence is straight, right turn, left turn; the second pattern is straight with simultaneous left and right turns. There may be slight variations in different cities and at different intersections.

I've been driving for over twenty years, and when encountering multiple traffic lights, I always take a moment to identify which light controls my lane. At intersections, each direction usually has its own set of signals—look at the one overhead or directly ahead, not the wrong direction. For example, watch the green straight arrow for going straight or the left-turn arrow for turning left. Once on a complex overpass, my straight light turned green while the turn signal stayed red—I waited until all were green to avoid a ticket. New drivers might panic, but practice makes perfect—the key is forming the habit of checking light colors for a few seconds before moving, safety first. Remember, light positions usually match lanes; don’t get distracted by other lanes to prevent rear-ends or violations.

What are the reasons for the engine oil warning light to come on?

Here are the reasons for the engine oil warning light to come on: 1. The engine temperature is too high: When the vehicle's engine is at a high temperature, it is very easy for the engine oil to become thin. The thinned oil will leak in large quantities from the matching gaps, leading to a drop in oil pressure, thus triggering the engine oil warning light. 2. Insufficient engine oil volume: Some car owners do not pay attention to the engine oil for a long time after adding it once, resulting in a gradual decrease in the oil volume in the oil pump. Insufficient oil volume in the oil pump will cause a drop in oil pressure, leading to the engine oil warning light coming on. 3. The matching gap between the crankshaft and the big and small bearings: Another reason for the engine oil warning light to come on is when the gap between the crankshaft and the big and small bearings is too tight, it will increase the oil pressure, while if it is too loose, it will cause the oil pressure to drop. 4. Damage to the oil pump: When the components of the oil pump are damaged or there are issues such as wear and tear or excessive gaps due to assembly problems, it will cause the oil pump to not pump oil or pump insufficient oil. This is the fourth reason for the engine oil warning light to come on.

Do small cars need to go through the inspection line after six years?

Small cars are required to undergo annual inspections at the inspection line after six years. Below is an introduction to small cars: 1. Overview: Small cars generally refer to models with a displacement of around 1.0-1.3 liters, such as those tested by European E-NCAP, Japanese J-NCAP, and C-NCAP. 2. Features: Small cars typically have low fuel consumption and a compact design, offering a more comfortable and spacious interior compared to micro cars. In the A-segment, besides micro and small cars, compact cars also fall within this category. 3. Market: Despite strong advocacy from central authorities, due to factors such as policies, fuel prices, and consumer attitudes, the market for 1.0L and below small cars remains sluggish, with sales even declining instead of increasing.

Can Car Keys Be Duplicated?

Car keys can be duplicated. Below is relevant information about car key duplication: 1. Methods for duplicating car keys: Authorized 4S dealerships can query the anti-theft password for key configuration from their database using the vehicle owner's driving license and ID documents. After obtaining this password, the dealership requires the key blade code to cut a new metal key. 2. Function of old keys: Once the new car key is successfully programmed, the lost key becomes invalid immediately. Even if someone finds the old key, they can only mechanically unlock the doors but cannot start the vehicle. Therefore, the security level of this 'code' becomes a major factor determining the pricing.

Differences Between Hardtop Convertibles and Soft Top Convertibles

Differences between hardtop convertibles and soft top convertibles lie in space occupation, cost, and safety aspects. Below are detailed introductions about the differences between hardtop convertibles and soft top convertibles: 1. Space Occupation: Compared to hardtops, soft tops can be folded more fully, thereby reducing space occupation. Soft tops are usually made of fabric, which saves a lot of weight compared to metal roofs. Additionally, the rear window of a soft top is typically made of plastic, which is much lighter than the glass of a hardtop. 2. Cost: The mechanical structure and electrical components of soft tops are fewer than those of hardtops, making them more affordable. For soft top models, the biggest concern is lifespan. Firstly, after years of sun exposure, the plastic rear window will become more fragile, and older soft tops are more prone to tearing on highways. 3. Safety: Hardtops offer better safety than soft tops, as soft tops are more vulnerable if the car rolls over. The rear window of a hardtop convertible is made of glass. Compared to the plastic glass of soft tops, it provides superior anti-theft performance and is more resistant to damage from sharp tools.

What is the fuel consumption during the break-in period of a new car?

During the break-in period, a new car consumes one to two units more fuel than after the break-in. If the fuel consumption does not decrease after the break-in period but instead becomes higher than during the break-in, it is necessary to promptly check the car's fuel injectors or throttle body. Below are some driving tips related to the break-in period: 1. Avoid high-speed driving: When driving a new car, it is important to control the speed. Excessive speed can cause significant wear and tear on the car, so it is necessary to regulate the engine speed between 2,000 to 4,000 RPM. This helps provide better protection while driving. 2. Avoid overloading the car: An overloaded car requires more power to drive, which can cause varying degrees of damage to various components. 3. Avoid sudden braking: While driving, try to avoid sudden braking. Braking in advance ensures smoother stops, reduces impact, and enhances passenger comfort.
