Motor vehicle traffic signals and non-motor vehicle traffic signals indicate: When the green light is on, vehicles are permitted to pass, but turning vehicles must not hinder the passage of through vehicles and pedestrians; When the yellow light is on, vehicles that have already crossed the stop line may continue to pass. When the red light is on, vehicles are prohibited from passing. At intersections without non-motor vehicle traffic signals or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle traffic signals. Additional information: Pedestrian crossings, overpasses, or underpasses should be installed at road intersections and sections with concentrated pedestrian crossings. In sections with frequent blind pedestrian traffic, audible signal devices should be installed for pedestrian crossing signals.

Wow, that's a great question! While most red lights indeed prohibit left turns, there are some exceptions at certain intersections. For instance, at intersections with designated left-turn waiting zones, you can move forward into the waiting area when the light is red. Also, at intersections with dedicated left-turn arrow signals, you can safely turn left when the arrow turns green, even if the straight-through light is red. However, the most important thing to note is at T-junctions: when you're facing a red light but there's no cross traffic, some places allow you to cautiously make a left turn, especially at T-junctions where there's no road to the right. But always remember to check local traffic signs—I once got ticketed in Jinan because I missed a small 'No Left Turn on Red' sign.

Can the 431 Read the Mileage of Volkswagen Transmissions?

431 reads the mileage of Volkswagen transmissions. Below is a detailed introduction about automotive transmissions: Overview: The transmission is a device that changes the speed ratio and direction of motion, typically located between the clutch and the central drive. It can alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a housing and several gears. Classification: Automatic transmissions have become mainstream internationally, mainly including AT, AMT, CVT, and DCT types. Early AT transmission systems were primarily 4AT. AT achieves automatic gear shifting through an electronically controlled automatic operating system. CVT is a true continuously variable transmission with fewer parts and a compact size. DCT has two clutches.

Why doesn't the new Bora have a shark fin antenna?

The new Bora does not have a shark fin antenna because the car antenna is arranged inside the car, so this form is also called a built-in antenna or hidden antenna. Advantages of installing a shark fin antenna: Unique and harmonious design, fully showcasing its charm, making the car body shape more perfect. Upgraded charm and taste, higher grade, highlighting the style of a luxury car. Anti-theft safety, the built-in structure effectively prevents antenna theft, with a higher safety factor. The first car series with shark fin antenna: In order to enhance the car communication signal, BMW developed the shark fin antenna specifically for BMW series models.

What brand is the original timing belt for the Octavia?

The original timing belt for the Octavia is from the Gates brand. Gates has been producing in mainland China for many years, and the Gates brand offers a comprehensive range of timing belt models. Introduction to timing belts: The timing belt is a crucial component of the engine's valve system, ensuring accurate intake and exhaust timing by connecting to the crankshaft and maintaining a specific transmission ratio. Regular replacement of the belt is necessary: Belts are used instead of gears for transmission because they produce less noise, have minimal self-variation, and are easier to compensate for. It is evident that the lifespan of a belt is shorter than that of metal gears, hence the need for regular replacement.

What are the defects of the N46 engine?

The N46 engine has issues with oil leaks from the valve cover gasket, cylinder head gasket, and burning oil due to aging valve stem seals. Below are the relevant details: 1. Sealing performance: This engine operates at a temperature of around 110°C. After driving 40,000 to 60,000 kilometers, the sealing performance of some rubber seals deteriorates. 2. Rubber hardening and brittleness: The valve cover gasket, which frequently operates under high temperature and pressure, causes the rubber to harden and become brittle over time, leading to reduced sealing performance and oil leaks from the valve cover gasket. 3. Deterioration of oil seal performance: The decline in sealing performance of the valve stem seals results in severe oil burning in the N46 engine, consuming approximately 1 liter of oil every 1,000 kilometers.

Can the Electronic Parking Brake Still Be Used After the Car Is Turned Off?

If the car is turned off without activating the electronic parking brake, the car's computer will automatically engage it, so the electronic parking brake remains functional after the engine is off. The following is an introduction to parking brakes: 1. Electronic Parking Brake: The electronic parking brake is a technology that uses an electronic system to control the vehicle's parking brake, achieving the same effect as a mechanical parking brake but with a different control method. 2. Advantages of Electronic Parking Brake: Its benefits include saving the space occupied by a mechanical parking brake, creating more central console space, being easy to operate and requiring less effort, as well as adding multiple functions such as auto start-stop and hill-start assist.
