Main road vehicles refer to those traveling on the main thoroughfares, while auxiliary road vehicles are those on roads that distribute traffic from expressways. Here are the detailed explanations: 1. Main Road Vehicles: Main roads are exclusively for motor vehicles, typically featuring 4 or 6 motor vehicle lanes and non-motorized vehicle lanes with dividers. Their capacity is enhanced by expanding intersections, and for particularly high-traffic main road intersections, overpasses may be constructed. The speed limit on main roads can exceed 80 km/h. Main roads are tasked with transporting long-distance motor vehicle traffic flows across regions. 2. Auxiliary Road Vehicles: Auxiliary roads accommodate mixed traffic of motor vehicles, non-motorized vehicles, and pedestrians. Depending on requirements, auxiliary roads can be intermittent between two interchanges or continuous through an interchange, located on one or both sides of an expressway, with one-way or two-way traffic. Generally narrower, auxiliary roads help alleviate pressure on main roads. The speed limit on auxiliary roads must not exceed 60 km/h.

Should I look at the right or left mirror for the right reverse parking in Subject 2?

At the starting position for reverse parking, look at the left mirror. When the edge line of the parking space aligns with the lower edge of the left mirror, start turning the steering wheel fully to the right. At this point, shift your focus to the right rearview mirror. Below are the relevant details: 1. Subject 1: Road traffic safety laws, regulations, and related knowledge test. It is a written test conducted on a computer, with a full score of 100, and a passing score of 90 or above (including 90). 2. Subject 2: Field driving skills test. It is a practical test conducted in a designated area, with only pass or fail results. The test includes five mandatory tasks performed in sequence: reverse parking, parallel parking, S-curve driving, right-angle turning, and hill start and stop. The full score is 100, with a passing score of 80 or above (including 80). 3. Subject 3: Road driving skills test. It is a practical test conducted on a road or simulated area, with a full score of 100. The passing scores are 90 or above for large buses, 80 or above for large trucks, and 70 or above for other vehicle types. 4. Subject 4: Safe and civilized driving knowledge test. It is a written test with a full score of 100, and a passing score of 90 or above (including 90).

Where is the fuse for the cigarette lighter?

The fuse for the cigarette lighter is located either inside the car or under the engine hood. For fuses placed inside the car, some are in the electrical fuse box inside the vehicle, while others may be in a small drawer below the driver's seat on the left side. Alternatively, you can trace other fuse wires to locate the cigarette lighter fuse. It is recommended to turn on the cigarette lighter before inserting the key. Most vehicles are equipped with a cigarette lighter, and some high-end cars even have an additional one in the rear for the convenience of backseat passengers. With advancements in automotive technology, the cigarette lighter is increasingly used to power various additional electronic devices in cars, such as GPS, MP3 converters, power inverters, electric shavers, car air compressors, and car wash pumps.

What are the main purposes of car cleaning?

Car cleaning serves three main purposes: 1. Maintaining a clean exterior appearance of the vehicle; 2. Creating a healthy interior environment: Areas such as carpets, seats, air conditioning vents, and the trunk frequently come into contact with moist air or water stains. In certain conditions, these areas can become breeding grounds for bacteria, leading to mold growth and unpleasant odors, which not only affect the air quality inside the car but also pose health risks; 3. Protecting the car's interior and extending its lifespan: Regular cleaning, disinfecting, and deodorizing of the car interior can effectively prevent various contaminants from damaging interior components like carpets, leather seats, and fabric upholstery.

Must the Tire Production Date Face Outwards?

Tire production date must face outwards. If the tire is installed incorrectly, the vehicle's comfort will be affected. For symmetric tread pattern tires, there is no distinction between inside and outside during installation, but the side with the production date should be placed on the outside. For unidirectional tread pattern tires, they should be installed following the direction of the arrow, which indicates the rolling direction of the wheel. Car tires are one of the important components of a vehicle, directly contacting the road surface and working together with the car suspension to mitigate the impact during driving. They ensure good ride comfort and smooth driving, as well as excellent adhesion between the wheel and the road surface, thereby improving the vehicle's traction, braking, and off-road capability.

What are the types of suspension systems?

Suspension systems can be categorized into two types: independent suspension and non-independent suspension. In an independent suspension system, each of the four wheels is connected to the vehicle body with its own suspension, allowing them to move up and down independently. On the other hand, a non-independent suspension system connects the left and right wheels with a shared suspension and axle, preventing independent up and down movement. The automotive suspension system refers to all the force-transmitting connection devices between the vehicle frame and the axle or wheels. It consists of elastic elements, guiding mechanisms, shock absorbers, buffer blocks, and a stabilizer bar. The functions of the automotive suspension system include: 1. Transmitting forces and torque between the wheels and the frame; 2. Absorbing shocks and vibrations from uneven road surfaces transmitted to the frame or body; 3. Ensuring the wheels move within a fixed angle to maintain stable steering; 4. Supporting the weight of the wheels; 5. Maintaining good contact between the wheels and the ground.
