Must the vehicle owner apply for ETC?

It is not mandatory for the vehicle owner to apply for ETC. According to the "Implementation Plan for Accelerating the Application Service of Electronic Non-stop Toll Collection on Highways" issued by the Ministry of Transport, the original valid ID card of the vehicle owner, the original and copy of the vehicle license, and the page of the vehicle license with the latest annual inspection stamp are required. If applying on behalf of others, the original valid ID card of the agent is also required. If applying for ETC through major bank branches, a debit card or credit card from the corresponding bank must be prepared. Some banks only support ETC binding with credit cards, while others may require freezing a certain amount as a deposit when binding ETC with debit cards. Documents required for company vehicles: Introduction letter from the vehicle owner (with official seal); copy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle license; vehicle for which ETC is to be applied. ETC deduction principle: There will be one or more ETC lanes on the highway. Through the dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle windshield and the microwave antenna in the ETC lane of the toll station, the computer network technology is used to settle accounts with the bank in the background, achieving the purpose of paying tolls without stopping at the toll station. All this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Save time: eliminates the hassle of waiting in line; Green and environmentally friendly: green and low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and pollution; Save wear and tear: saves costs, reduces the frequency of vehicle starts and brakes, and reduces wear and fuel consumption; Improve efficiency: the theoretical efficiency of ETC lanes can be increased by 2-3 times, making traditional ETC newer, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key urban agglomerations will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased," and clearly proposed in the main indicators of the "13th Five-Year" comprehensive transportation development that "by 2020, the ETC usage rate of road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate of passenger vehicles, the future will also promote the use of ETC by trucks, explore the deep integration of the ETC system with the development direction of smart transportation such as vehicle-to-vehicle communication and vehicle-road coordination, and provide vehicle owners with comprehensive travel services, which means more application scenarios will support ETC applications. Precautions for using ETC: The ETC transaction sensing area is 8 meters. When encountering a vehicle in front stopping, to prevent the ETC device of the vehicle in front from malfunctioning or not having an ETC device at all, keep a distance of more than 10 meters from the vehicle in front to prevent automatic sensing from paying for the vehicle in front. The recognition speed of ETC lanes is 20km/h. If the speed is too fast, the vehicle device information cannot be read, and the fee deduction will fail. Unauthorized disassembly or movement of the OBU device, or the ETC electronic tag falling off or loosening, will cause the electronic tag to fail. It can be sent to the bank where the ETC card was applied for or the highway service office for testing. If it is not caused by human factors, it only needs to be reactivated. When using a debit card to bind ETC, insufficient balance will also cause the fee deduction to fail. You can follow the guidance of the on-site staff to go to the manual MTC lane and pass by using cash or swiping the card. Poor sensing due to the thick windshield of the car. Especially for vehicles that have been repaired and replaced the windshield after an accident, or friends who have modified the front windshield need to pay attention.

Does the BMW 3 Series Skid in Rain or Snow?

BMW 3 Series performs well in rain or snow. Some models of the 3 Series are rear-wheel drive, but as long as you control it properly, skidding won't be an issue. Reasons for Skidding: Many rear-wheel-drive cars tend to skid in snowy conditions, especially high-performance vehicles. This is because front-wheel-drive cars, where the front wheels are the driving wheels, can be visualized as "pulling" the car forward. Front-engine, front-wheel-drive vehicles are prone to understeer during turns, although most cars today use this drivetrain layout. Similarly, rear-wheel-drive cars, where the rear wheels are the driving wheels, can be thought of as "pushing" the car forward. Front-engine, rear-wheel-drive vehicles are more likely to oversteer during turns. This drivetrain configuration is commonly used in luxury sedans, such as BMW's entire lineup, which exclusively features rear-wheel drive. Why Front-Wheel Drive Skids Less: Front-wheel-drive cars experience these issues much less frequently than rear-wheel-drive cars, and the reason is quite simple. Typically, front-wheel-drive cars have a front-heavy weight distribution, with the driving wheels bearing the weight of the engine, transmission, and other mechanical components. This naturally increases the traction between the front wheels and the road surface. Additionally, the "pulling" nature of front-wheel drive gives these cars better performance on icy or snowy roads compared to rear-wheel-drive vehicles.

Is the Audi A3 front-wheel drive?

Audi A3 models are front-wheel drive vehicles. According to the manufacturer's model specifications, all FAW Audi A3 models currently on sale are front-wheel drive. Introduction to front-wheel drive: Front-wheel drive (FWD), also known as front-engine front-wheel drive, refers to a power distribution method in automotive design where the engine only drives the front pair of wheels. Most sedans adopt a front-wheel drive configuration. Early cars were rear-wheel drive, and trucks still use rear-wheel drive, but this does not necessarily indicate advancement or superiority. Characteristics of front-wheel drive: Compared to rear-wheel drive, front-wheel drive designs are less expensive in terms of both design and assembly. The mechanical components of front-wheel drive are fewer and simpler than those of rear-wheel drive, which helps reduce weight significantly. Front-wheel drive does not require space for rear-drive equipment under the floor, allowing for more flexibility in space utilization.
