What Causes Engine Shaking and Malfunction Light Illumination?

Engine shaking accompanied by the illumination of the malfunction indicator light may be caused by engine misfire, excessive carbon buildup in the intake system, or issues within the ignition system. There are two scenarios for the malfunction light being on: 1. The light is on, but the vehicle drives normally without any noticeable abnormalities in acceleration or braking, and can currently be operated. This could be due to a one-time sensor malfunction, interference from certain external conditions, or a fault that doesn't affect driving performance but may have some impact on emissions. In this case, you may continue driving temporarily but should have the vehicle inspected at a repair shop. 2. The malfunction light is on, and the vehicle exhibits obvious abnormalities such as severe shaking or lack of power during acceleration. In this situation, it's best not to continue driving and to request roadside assistance or a tow truck. If the repair shop is very close, you may cautiously drive there. Since there are clear symptoms of a malfunction, this indicates a relatively serious issue. Continuing to drive could worsen the fault or allow the damage to accumulate, potentially leading to additional failures. Therefore, it is not recommended to continue driving under these circumstances.

Can motorcycles carry passengers on highways?

Motorcycles are not allowed to carry passengers on highways, and regulations vary by region. Whether motorcycles can access highways depends primarily on local policies. According to the Road Traffic Safety Law, non-motorized tractors, wheeled special-purpose motor vehicles, or other vehicles with a maximum speed below 70 km/h are prohibited from entering highways. However, most motorcycles can exceed 70 km/h, so under road traffic regulations, motorcycles are generally permitted on highways. Nonetheless, local regulations differ, and the final decision rests with regional policies. To ride a motorcycle on a highway, the following three conditions must be met: wearing a helmet, no passengers allowed, speed not exceeding 80 km/h, and riding on the right side of the road with speed maintained between 70 km/h and 80 km/h. Additionally, carrying large items is prohibited, and a valid motorcycle license must be carried. Latest regulations for motorcycles on highways: According to the new standard "Toll Road Vehicle Classification" issued by the Ministry of Transport, motorcycles are permitted on highways starting September 1, 2019. This policy aims to facilitate travel and serves as a welfare benefit. The new standard specifies classifications for various vehicles, including motorcycles, and categorizes motorcycles under Class I passenger vehicles for toll purposes. Furthermore, the standard increases the seating capacity for Class I vehicles from 7 to 9, meaning 9-seat and smaller vehicles are classified as Class I passenger vehicles after September 1, 2019.

Does the Tire Pressure Monitoring System Need to Be Reinstalled After Changing Tires?

After changing tires, the tire pressure monitoring system needs to be reinstalled. The tire pressure monitoring, also known as tire pressure learning, involves a pressure sensor in each tire that wirelessly transmits the tire pressure to the vehicle's tire pressure control system. The vehicle's data display can then show the tire pressure for each specific tire location. There are three common types of tire pressure monitoring methods: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. The system automatically alerts when the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): TPMS combines the advantages of both systems mentioned above. It is equipped with direct sensors in two diagonally opposite tires and includes a four-wheel indirect system. Compared to a fully direct system, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires, as a direct system does.

Can You Get Rewards for Reporting Illegally Parked Vehicles?

You can get rewards for reporting illegally parked vehicles. When encountering illegally parked vehicles on the road, users can take photos and upload them. After the photos are submitted to the traffic police platform and verified as valid reports, users can receive rewards. The rewards are not contingent on the vehicle owner paying the fine; users can receive rewards directly. Legal basis for reporting illegally parked vehicles: Article 63 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates the following rules for temporary parking of motor vehicles on roads: Parking is prohibited in sections with no-parking signs or markings, in sections with isolation facilities between motor vehicle lanes and non-motor vehicle lanes or sidewalks, and in crosswalks or construction zones. Parking is also prohibited at intersections, railway crossings, sharp curves, narrow roads less than 4 meters wide, bridges, steep slopes, tunnels, and within 50 meters of these locations. Additionally, parking is prohibited within 30 meters of bus stops, emergency stations, gas stations, fire hydrants, or fire stations, except when using these facilities. Doors must not be opened or passengers allowed to board or alight before the vehicle comes to a complete stop, and opening doors must not obstruct other vehicles or pedestrians. Vehicles parked on the roadside must stay close to the right side of the road, and the driver must not leave the vehicle; the vehicle must depart immediately after passengers board or alight or goods are loaded or unloaded. City buses must not stop to pick up or drop off passengers outside designated bus stops.

Can I Request a Replacement Vehicle if There Are Issues Upon Delivery?

If a new vehicle has faults or issues that meet certain conditions, it can be replaced. Within the warranty period for household automotive products, if the conditions for replacement or return stipulated in the regulations are met, consumers can request a replacement or refund from the seller by presenting the warranty certificate, purchase invoice, and other relevant documents. During the warranty period for household automotive products, if any of the following situations occur and the consumer chooses to replace or return the vehicle, the seller is responsible for the replacement or refund: (1) The vehicle has undergone repairs for serious safety performance faults twice, and the faults persist or new serious safety performance faults emerge. (2) The engine or transmission has been replaced twice, or the same major component of the engine or transmission has been replaced twice due to quality issues, and the vehicle still cannot function normally (the replacement counts for the engine or transmission and their major components are not cumulative). (3) The same major component of the steering system, braking system, suspension system, front/rear axle, or body has been replaced twice due to quality issues, and the vehicle still cannot function normally. The major components of the steering system, braking system, suspension system, front/rear axle, and body must be clearly listed by the manufacturer on the warranty certificate, and their categories should comply with relevant national standards or regulations. Specific requirements will be further stipulated by the General Administration of Quality Supervision, Inspection, and Quarantine.

Is a U-Turning Vehicle Always Fully Liable in a Collision?

Determining liability when a vehicle is hit while making a U-turn depends on the specific circumstances. The U-turning vehicle is responsible for observing road conditions; turning and U-turning vehicles must yield to through traffic. If the U-turning vehicle completes the maneuver without carefully assessing the road conditions while other vehicles are proceeding normally, the U-turning vehicle should bear full liability. If a dashcam is available, presenting video evidence can help, or wait for the traffic police to issue an accident liability determination report. Relevant regulations: According to Article 49 of the "Regulations for the Implementation of the Road Traffic Safety Law", motor vehicles are prohibited from making U-turns at locations with no U-turn or no left-turn signs or markings, as well as at railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, or other hazardous sections. Motor vehicles may make U-turns at locations without no U-turn or no left-turn signs or markings, provided they do not obstruct the passage of other normally traveling vehicles and pedestrians. Article 52 states: When motor vehicles pass through intersections without traffic signals or traffic police direction, in addition to complying with the provisions of Items (2) and (3) of Article 51, they must also adhere to the following rules: when there are traffic signs or markings, yield to the party with the right of way; when there are no traffic signs or markings, stop and observe before entering the intersection, yielding to vehicles coming from the right; turning motor vehicles must yield to through traffic; right-turning vehicles from the opposite direction must yield to left-turning vehicles.
