Which gear should be used for lane changing in Subject 3?

There is no specified gear for lane changing in Subject 3. The degree of steering wheel movement during lane changing in Subject 3 is inversely proportional to the vehicle speed. This means that the faster the speed, the smaller the steering wheel movement should be; if the speed is slow, the steering wheel movement should be slightly larger. Generally, for lane changing, the steering wheel movement should be controlled at around 10 degrees. Below are the relevant details: 1. Using 1st gear for overtaking in Subject 3 is not allowed. Lane changing and overtaking without accelerating will result in too low speed, and mismatched gear and speed will lead to test failure; 2. The content of the Subject 3 road driving skill test includes large buses, tractors, city buses, medium buses, large trucks, small cars, small automatic transmission cars, low-speed trucks, and small automatic transmission cars for the disabled; 3. The test includes preparation before getting on the car, simulated nighttime light test, starting, driving straight, gear shifting operation, lane changing, parking by the roadside, going straight through intersections, turning left at intersections, turning right at intersections, passing pedestrian crossings, passing school areas, passing bus stations, meeting vehicles, overtaking, turning around, and nighttime driving; the test content for other permitted vehicle types is determined by the provincial traffic management department of the public security authority.

Can an Air Conditioning Outdoor Unit Fit in a Sedan's Trunk?

Different car models have varying trunk sizes, and generally, a mid-sized car can accommodate an air conditioning outdoor unit. Here is some extended information about the trunk: 1. Essentials: Reflective warning triangle, used to alert vehicles behind in case of a breakdown. Fire extinguisher, for unexpected vehicle fires. Dust brush, mainly used for cleaning the windshield. Small emergency light, for signaling help or self-rescue; tools like wrenches and a jack, for changing a flat tire. 2. Precautions: Do not fill the trunk to capacity during daily short-distance driving; do not use the trunk as a 'storage room'; do not leave or forget food in the trunk. It is best to use trunk mats made of synthetic fibers, cotton, or wool, and avoid heavy floor coverings, as a set of floor coverings can weigh between 10 to 15 kilograms, which can affect fuel consumption. Do not store flammable or explosive items like lighters or hairspray in the trunk, as the trunk is a more enclosed space. In hot weather, combined with road bumps, these items could potentially explode.

How Many Models Does the Aisin 6AT Transmission Have?

Aisin 6AT transmission has 3 models. The following is an introduction to the transmission-related content: 1. 6AT Transmission: Except for shifting from P to D at the start and from D to P when parking, the D gear can be used from beginning to end. The Sport gear can be used when starting, but on flat roads, the speed increase with Sport gear is not as fast as with D gear. The S gear has excellent acceleration performance and is used for overtaking when a certain speed has been reached. When the car is running, shifting the D gear to the left can switch to M gear mode, and the gear can be controlled by pushing the gear lever forward or backward. 2. Classification: Car transmissions can be divided into manual transmissions and automatic transmissions, and AT is the commonly referred to automatic transmission. The gears of an automatic transmission are divided into P, R, N, D, 2, 1, or L, etc. 6AT means six forward gears, that is, six sets of gear groups with different transmission ratios. Others include 4AT, 8AT, 9AT, and even 10AT. Although the preceding numbers are different, they are all derivatives of automatic transmission technology.

What are the consequences of having 11 points deducted from a C-class license?

C1 driver's license with 11 points deducted has no significant impact, but it cannot reach 12 points. If you are in the probationary period and accumulate 12 points, your license will be directly revoked. Even if you are not in the probationary period, accumulating 12 points will result in your license being suspended, and you will need to undergo training to retrieve it. Below is an introduction to driver's license point deductions: 1. According to Article 68 of the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses': If a motor vehicle driver accumulates 12 points within a scoring cycle, the traffic management department of the public security organ shall detain their motor vehicle driver's license. The driver must report to the traffic management department of the public security organ at the place where the license was issued or where the violation occurred within 15 days to participate in a seven-day study of road traffic safety laws, regulations, and related knowledge. 2. After the driver completes the study: The vehicle management office shall conduct an examination on road traffic safety laws, regulations, and related knowledge within 20 days. If the examination is passed, the points will be cleared, and the driver's license will be returned. If the examination is not passed, the driver must continue studying and retake the examination. Refusal to participate in the study or examination will result in the traffic management department of the public security organ announcing the suspension of the driver's license.

How Should Compensation Be Handled When a Motor Vehicle Collides with an Over-standard Electric Vehicle?

When a motor vehicle collides with an over-standard electric vehicle, the compensation is primarily determined based on the accident scene conditions and the accident liability certificate issued by the traffic police. There is no inherent connection with whether the electric vehicle exceeds standards or is classified as a motor vehicle. If the motor vehicle is deemed responsible, the liability proportion cannot be reduced on the grounds that the electric vehicle is a non-motor vehicle during civil compensation. The liability division for motor vehicle traffic accidents is as follows: 1. Traffic accident liability ratio: For accidents between motor vehicles, the party at fault bears the traffic accident compensation liability. If both parties are at fault, the liability is shared according to their respective fault proportions: the party primarily responsible bears 70%; equally responsible parties bear 50%; the party secondarily responsible bears 30%. 2. Motor vehicle liability ratio: For accidents between motor vehicles and non-motor vehicles, or between motor vehicles and pedestrians, the motor vehicle party bears the liability for the portion exceeding the liability limit. However, if there is evidence that the non-motor vehicle driver or pedestrian violated traffic safety laws and regulations, and the motor vehicle driver has taken necessary measures, the motor vehicle party primarily responsible bears 80%; equally responsible bears 60%; secondarily responsible bears 40%; if the motor vehicle party is not at fault, it bears 10%.
