Is ETC Mandatory to Install?

It is not mandatory but encouraged for vehicle owners to install ETC. According to the State Council's regulations, vehicles without ETC after 2020 will not enjoy toll discounts, and in the future, only one manual lane will remain at highway toll stations, requiring manual fee payment. Additionally, newly installed ETC devices cannot be used on highways immediately; activation is required before normal use. During free holiday periods, ETC users can still use highways without being charged when passing through ETC lanes. The principle of ETC charging: Highways will have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane, combined with computer networking technology for backend bank settlement, vehicles can pass toll stations without stopping to pay bridge and road fees. This is all based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Promotes low-carbon travel by reducing noise and exhaust emissions since vehicles don't stop at toll stations; Reduced wear: Saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption; Improved efficiency: ETC lanes can theoretically increase passing efficiency by 2-3 times, making traditional ETC 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, intercity transportation smart cards should be basically interoperable in key city clusters, and the proportion of vehicles equipped with ETC should significantly increase." It also set a target in the main indicators of comprehensive transportation development during the "13th Five-Year Plan" to "achieve a 50% ETC usage rate for road passenger vehicles by 2020." More future possibilities: Besides continuously improving the convenience of ETC installation and usage rates for passenger vehicles, future efforts will promote ETC use for trucks and explore deeper integration of ETC systems with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation developments. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC usage.

What Components Make Up the ABS System?

ABS system mainly consists of 4 components: Wheel speed sensor, electronic control unit (ECU), hydraulic unit, and ABS warning light. The wheel speed sensor detects the motion state of the wheels, generates sinusoidal electronic pulse AC signals, which are then processed by the modulator to convert the pulses into digital signals and transmit them to the electronic control unit. The electronic central control unit (ECU) receives input signals from the wheel speed sensors, uses these parameters to calculate the wheel speed, vehicle speed, and slip ratio, determines the wheel state based on the slip ratio, and issues control commands to the hydraulic unit. The hydraulic unit adjusts the pressure in the brake lines according to the control commands, with the adjustment process including pressure holding, pressure increase, and pressure decrease. The ABS warning light alerts the driver to system malfunctions and is displayed on the instrument panel.

Do Turn Signals Turn Off Automatically?

Turn signals generally require manual deactivation. After engaging the turn signal, when the steering wheel returns to the central position, you'll hear a faint "click" sound indicating reset. However, if the steering angle during lane changes is too slight, the signal won't automatically reset. Below are relevant explanations: 1. Function of turn signals: As the most frequently used lighting feature, turn signals clearly communicate intended driving directions to surrounding vehicles. Yet many drivers neglect proper turn signal usage during operation, with some even unaware of appropriate usage scenarios, creating significant safety hazards. Therefore, understanding proper turn signal application is essential. 2. Timing for activation: Turn signals primarily notify trailing vehicles of intended turns, prompting caution. Drivers should activate signals 10-20 seconds before turning to provide adequate reaction time. 3. Activation verification: Determining whether turn signals are engaged is straightforward - simply check the instrument panel for the corresponding indicator light (as shown in the diagram above). These indicators display turn signal positioning, normally remaining off. When activated, the directional indicator illuminates accordingly and extinguishes automatically upon signal deactivation.

Does Subject 4 Require an Appointment?

Subject 4 does not require an appointment. Additional information is as follows: 1. Introduction: Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license assessment. The original examination consisted of the Subject 1 theory test, Subject 2 yard test, electronic Subject test, and Subject 3 road test. Subject 4 separates the requirements for safe and civilized driving, safe driving skills under complex conditions, and emergency handling knowledge from the original Subject 1, placing them after the "Subject 3" practical road driving test to further assess the candidate's level of traffic awareness. 2. Test Content: The main content includes: requirements for safe and civilized driving operations, knowledge of safe driving under adverse weather and complex road conditions, emergency handling methods for situations such as tire blowouts, and knowledge of post-traffic accident handling.

When is the best time for the first maintenance of a Volkswagen car?

Generally, the first maintenance is recommended at 6 months or 5,000 kilometers, whichever comes first. The vehicle maintenance manual's appendix provides details about the maintenance cycle, duration, and items. Here is some additional information: 1. Car warranty period: The car warranty period refers to the time frame during which the car manufacturer promises to provide free repairs and maintenance for faults caused by quality issues when selling the product to consumers. 2. Warranty duration: Most car manufacturers now implement a new vehicle warranty period, "two years or 60,000 kilometers, whichever comes first." This means there are two conditions for the warranty period: one is a time limit of 2 years, and the other is a mileage limit of 60,000 kilometers. If either condition is met, the vehicle's warranty period is considered expired, and normal maintenance and repairs will no longer be free. 3. Specified free warranty items: During the warranty period, not all repair costs will be waived, but only those items specified by the manufacturer. Usually, the owner's manual and the after-sales departments of car 4S stores have relevant written instructions. Therefore, car owners are advised to read the manual carefully to avoid unnecessary expenses during the warranty period.

Can the license plate number be retained when selling a car?

Yes, it can be retained. After the transfer or scrapping of the old car, if the original owner meets the requirement that the license plate number has been used for one year, they can use the original license plate number whether they purchase a new car or a used car. Alternatively, they can opt for a new number. If the original owner does not apply to use the number within one year, the license plate will be returned to the selection pool and made available to the public. According to the new license plate management policy, the original license plate can be retained as long as the following conditions are met: 1. Usage period: The license plate must have been used for more than one year (previously, the requirement was three years). 2. Application period: The time limit to apply for retaining the original number has been extended to one year (previously, the application had to be made within six months after the transfer or scrapping of the original vehicle). 3. Clearance of violations: All traffic violation records associated with the original vehicle must be cleared.
