What is the safe driving distance on highways during snowy conditions?

Snowy roads are slippery, and the braking distance is longer than on dry asphalt roads; visibility is low in snowy conditions, so the safe distance should be controlled according to visibility. Visibility below 200 meters: the speed should not exceed 60 km/h, and a minimum distance of 150 meters should be maintained from the vehicle ahead in the same lane to ensure safety. Visibility below 50 meters: the maximum speed should be 20 km/h, and you should exit the highway at the nearest exit. Longer safe distance: In adverse weather conditions such as rain, snow, or fog, where visibility is low, the road is slippery, and vehicle load affects performance, the safe distance should be longer than on dry asphalt roads. The safe distance on snowy or icy roads is three times that on dry roads. Due to slippery roads in snowy conditions, stay updated on road conditions and minimize driving if possible. When driving on icy or snowy roads, stay focused, maintain a safe distance, drive at a low and steady speed, and avoid unnecessary lane changes or overtaking. When braking, use intermittent braking or downshift to reduce speed. When turning, slow down and increase the turning radius. Anticipate situations and reduce speed in advance, avoiding sharp turns or sudden braking. Snow-covered or icy roads have low friction coefficients, reducing braking efficiency and increasing the risk of skidding. When driving through sharp curves or slippery roads prone to skidding, strictly control your speed. If the vehicle skids, do not sharply turn the steering wheel or apply emergency brakes. Maintain a low and steady speed while driving in snowy conditions, avoiding unnecessary lane changes or overtaking. When starting on icy or snowy roads, gently accelerate and slowly release the clutch. During driving, maintain a safe speed and distance, and follow existing tire tracks when possible. Avoid driving on snow-covered or unknown road sections.

How many meters are required for lane changing in Subject 3?

Overtaking and lane changing in Subject 3 must be completed within 100 meters. There are no specific requirements for speed and gear, as long as you are faster than the vehicle being overtaken, but you should ensure that the gear matches the speed. Additionally, pay attention to the speed limit of the test road to avoid speeding. There are three deduction standards in the Subject 3 test: deducting 5 points, deducting 10 points, and deducting 100 points. Different deduction standards have different detailed rules, which need to be carefully read and familiarized with. Deduct 100 points: Before stopping, failing to observe the traffic conditions behind and to the right through the interior and exterior rearview mirrors; after the examiner issues the command to pull over, failing to stop within the specified distance; after stopping, the vehicle body exceeds the right edge of the road or the sidewalk edge; after stopping, failing to turn the head to observe the side rear and left traffic conditions before opening the door inside the vehicle; after getting out of the car, failing to close the door. Deduct 10 points: After stopping, the distance between the vehicle body and the right edge of the road or the sidewalk edge is more than 30cm; after stopping, failing to tighten the parking brake; releasing the foot brake pedal before tightening the parking brake. Deduct 5 points: Failing to turn off the engine before getting out of the car.

Can a new car be returned or exchanged if it malfunctions?

New cars can be returned or exchanged if they malfunction, but there are strict regulations regarding the conditions for returns or exchanges. The relevant regulations on car warranties and returns/exchanges are primarily based on the "Regulations on the Repair, Replacement, and Return of Household Automotive Products" issued by the General Administration of Quality Supervision, Inspection, and Quarantine, commonly known as the "Automobile Three Guarantees." Below are the conditions for returning or exchanging a car: 1. Service Target: The service targets household automotive products, which refer to passenger vehicles purchased and used by consumers for personal consumption. If the car is purchased for rental purposes, such as leasing to a car rental company or for ride-hailing services like Didi or Hitch, or for other commercial purposes, it is not covered under the three guarantees for car returns or exchanges. 2. Time Regulations: The time frame for returning or exchanging a car must be within 60 days from the date of the purchase invoice or within 3,000 kilometers of driving (whichever comes first). This means that if more than two months have passed since the purchase, the car generally cannot be returned or exchanged. The warranty period for the car is no less than 3 years or 60,000 kilometers. 3. Other Conditions: If the car has undergone two repairs for the same serious safety performance fault and the fault remains unresolved or a new serious safety performance fault occurs, the consumer may choose to return or exchange the vehicle.

How soon can a new car be transferred to someone else?

A new car can be transferred to someone else the day after completing the registration procedures, with no time restrictions. For the transfer, both parties need to bring their ID cards, the vehicle license, and the motor vehicle registration certificate. As long as the new car has all the necessary documents, is free from any mortgage or pledge, and has no outstanding traffic violations or accidents, it can apply for the transfer procedure at any time. Here are four types of vehicles that cannot be transferred: 1. Vehicle identification code does not match the engine hood code: Such vehicles are usually of unknown origin, often being smuggled or modified cars. Even if purchased, they cannot be registered or transferred. 2. Failed to meet environmental inspection standards: Starting from 2018, China implemented the National V emission standard nationwide. Vehicles meeting National III or IV standards could not be registered even if purchased. With increasingly strict environmental standards, the National VI standard followed soon after. It is advisable to purchase vehicles meeting at least National V standards. 3. Vehicles without a certificate of conformity: The certificate of conformity is another crucial document for a car and is essential for registration. Without it, the car cannot be registered or transferred. 4. Non-compliant vehicle frame number: Every vehicle has a unique frame number, much like a person's ID card. Many stolen or cloned vehicles have their frame numbers altered when forging license plates.
