What are the vision requirements for a driver's license physical examination?

Vision requirements are: naked vision or corrected vision of both eyes must reach 4.9 or above on the logarithmic visual acuity chart, with no red-green color blindness. Below is relevant knowledge about the driver's license physical examination: 1. Height requirements: For large buses, tractors, city buses, large trucks, and trolleybuses, the height must be 155 cm or above; for medium-sized buses, the height must be 150 cm or above. Color discrimination: No red-green color blindness. 2. Hearing requirements: Each ear must be able to distinguish the direction of sound at a distance of 50 cm from a tuning fork. Those with hearing impairments who can meet the above conditions with hearing aids may apply for a driver's license for small cars or small automatic transmission vehicles.

Which Came First, Traffic Lights or Cars?

The world's first traffic light appeared before the advent of cars. The first traffic light in the world was installed in Parliament Square, London, UK. Below is relevant information about traffic lights: 1. Traffic Lights: Also known as Traffic Signal Lights, they are indicators that instruct vehicles and pedestrians whether to proceed or not. 2. Locations: They are typically installed at intersections and other areas requiring traffic control, generally consisting of red, green, and yellow lights. The red light means stop, the green light means go, and the yellow light serves as a warning. 3. Categories: Common types of traffic lights include motor vehicle signals, non-motor vehicle signals, pedestrian crossing signals, directional indicators (arrow signals), and flashing warning signals.

What are the reasons for the sudden disappearance of the 360-degree panoramic view in the car?

The reasons why the car's 360-degree panoramic view suddenly stops working: First, check if the screen is damaged; second, check for wiring issues; finally, inspect the battery module and power supply problems. It is recommended to seek professional help for inspection and troubleshooting. Here is some additional information: 1. Working principle: The working principle of the 360-degree panoramic view function is not complicated and can even be considered an enhanced version of the reverse camera function. It uses four ultra-wide-angle lenses distributed around the front, rear, left, and right of the car body to capture real-time images of their respective areas. The image processing unit then corrects distortions, converts perspectives, and stitches the images together, ultimately displaying a complete real-time 360-degree top-down view on the central control screen. This view allows for a very intuitive display of the real-time surroundings of the vehicle, enabling safer and more reliable parking. 2. Function: The 360° panoramic view helps eliminate blind spots for the driver. By providing a dead-angle-free driving record, it effectively reduces the occurrence of scratches, scams, and other accidents, ensuring driving safety. It has already become a 'hot trend' in the automotive aftermarket electronics sector.

Is Continuous Lane Changing Considered a Violation?

Continuous lane changing is not considered a violation. Relevant details are as follows: 1. Regulations: Violating prohibited markings includes crossing solid yellow lines (indicating no crossing of the central divider) and yellow X markings (indicating no parking). Driving over these constitutes a violation of prohibited marking instructions. Solid line lane changes, making U-turns in no-U-turn zones, and left turns where prohibited are punishable by a 200 yuan fine and 3 penalty points. 2. Additional Information: Both single and double solid yellow lines are prohibited markings. Crossing or driving over these lines is illegal. Failing to follow directional markings at intersections, making U-turns in no-U-turn zones, and performing prohibited left turns are punishable by a 200 yuan fine and 3 penalty points.

What are the gears of a manual-automatic transmission car?

The gears of a manual-automatic transmission are divided into P, R, N, D, 2, 1 or L, etc. There are also "+" and "-" gears. Below is relevant information about manual-automatic transmissions: 1. Introduction: A manual-automatic transmission is essentially a type of automatic transmission that simulates the operation of a manual transmission through an electronic control system. The manual-automatic transmission is designed to enhance the fuel efficiency and control of an automatic transmission by allowing the driver to decide the shifting timing, which was originally determined by the computer. At the same time, in urban traffic congestion, the automatic mode can still be used for convenience. 2. Pros and Cons: Besides the advantages of an automatic transmission, a manual-automatic car also allows manual control, providing some driving pleasure. The biggest disadvantage of a manual-automatic car is its higher fuel consumption. The manual mode is not fully manual and is limited by sensors, meaning it is impossible to shift directly to 1st, 2nd, or 3rd gear at 120 km/h. It is understood that the manual mode is rarely used in practice. Compared to automatic transmissions, the technology is not yet mature.

Reasons for Frozen Car AC Pipes but No Cool Air Output

When water enters the AC pipes, it can freeze and cause an ice blockage, preventing the refrigerant from circulating in the AC system. The refrigerant in the low-pressure section of a car's AC system has a very low temperature and freezing point, so it doesn't freeze inside the system. The refrigerant absorbs heat in the low-pressure section, creating a cooling effect. However, water freezes at 0 degrees Celsius, leading to ice formation. Related information: 1. Types of car AC systems: Integrated heating and cooling AC systems, where components like the evaporator, heater core, centrifugal blower, and control mechanism are assembled together, known as the AC unit assembly. 2. AC compression: The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature, high-pressure gas before discharging it. 3. AC heat dissipation: High-temperature, high-pressure refrigerant gas enters the condenser, where it condenses into a liquid due to reduced pressure and temperature, releasing a significant amount of heat. 4. AC throttling: High-temperature and high-pressure refrigerant liquid expands after passing through the expansion device, causing a sharp drop in pressure and temperature, and is discharged as a mist.
