What are the reasons for ETC not working?

Reasons for ETC not working: Insufficient battery power in the ETC device prevents it from starting. The ETC electronic tag has become invalid. When passing through the ETC lane, the vehicle's speed is too high for the system to read the information. ETC lane reading failure or insufficient balance on the ETC card can cause unsuccessful fee deduction. Malfunction of the OBU device. After the OBU is installed and activated on the vehicle's windshield, if it is accidentally detached, the OBU will be locked. Reinserting the ETC card will prompt "invalid tag". It is recommended to reactivate it. ETC usage precautions: The ETC transaction sensing range is 8 meters. When the vehicle in front stops, to prevent the ETC device of the front vehicle from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters to avoid automatic fee deduction for the front vehicle. The ETC lane recognition speed is 20km/h. If the speed is too high, the vehicle device information cannot be read, leading to fee deduction failure. Unauthorized removal or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to fail. It can be sent to the bank where the ETC card was issued or the highway service office for inspection. If the loosening or detachment is not due to human factors, simply reactivate it. When using a debit card linked to ETC, insufficient balance can also cause fee deduction failure. Follow the guidance of on-site staff to use the manual MTC lane, paying with cash or card. Thick car windshields can cause poor signal reception. This is especially important for vehicles that have had their windshields replaced after accidents or for those who have modified their front windshields.

What are the precautions for registering for a driver's license test?

When registering for a driver's license test, pay attention to the following precautions: 1. Verify the driving school's qualifications: Legitimate driving schools not only have a business license but also possess a road transport permit, etc. 2. Ensure that enrollment staff do not make arbitrary promises: Protect your own interests from being violated. 3. Check for additional fees: Pay attention to whether the price is all-inclusive and whether there are any other additional charges during the process. Generally, the more all-inclusive the price, the less likely there are to be random fees. 4. Confirm if there are any restrictions on practice time: If there are time restrictions, clarify the exact amount of practice time available to ensure you have sufficient time to learn and practice driving.

How long can a car run continuously on the highway?

Continuous driving of a motor vehicle for more than 4 hours should be accompanied by a rest stop, with the rest period lasting no less than 20 minutes. Assuming an average highway speed of 100 km/h, 1 hour equates to 100 kilometers. This means that after driving 400 kilometers on the highway, the driver needs to stop and rest at a service area. Precautions for highway driving are as follows: 1. Pay attention to speed: Avoid driving too slowly, with speeds not falling below 80 km/h. 2. Do not occupy the emergency lane: In the event of an accident, the emergency lane serves as a lifeline. Moreover, the penalties for illegally using the emergency lane are quite severe, including a fine of 200 yuan and a deduction of 6 points from the driver's license.

Will Insurance Cover Windshield Cracks?

The issue of insurance coverage for windshield cracks needs to be analyzed on a case-by-case basis: 1. Caused by a car accident: A. If the windshield crack is caused by a car accident and the other party is at fault, then the other party's compulsory traffic insurance and third-party liability insurance can be used for compensation. B. If the accident is your own fault, as long as you have collision insurance, you can use it to compensate for your windshield. 2. Caused by other factors: A. If the windshield crack is not caused by a car accident but by other factors, then only if you have purchased glass insurance can you claim compensation. B. If the windshield is damaged by someone else and cracks appear, you can directly seek compensation from the responsible party.

Are New Energy Vehicles Subject to Traffic Restrictions in Beijing?

According to Beijing's traffic management regulations, pure electric vehicles with blue license plates are not subject to traffic restrictions. Here is some relevant information: 1. About new energy vehicles: New energy vehicles produce minimal pollution and are more environmentally friendly compared to fuel-powered vehicles. Pure electric vehicles can achieve zero pollution during operation and do not emit harmful gases that pollute the atmosphere. Even when converting the electricity consumption to power plant emissions, the pollution caused is far less than that of traditional vehicles, as power plants have higher energy conversion rates. 2. Relevant information: With oil prices soaring today, the operating costs of electric vehicles are significantly lower than those of traditional fuel-powered vehicles. The noise and vibration levels produced by electric vehicles during operation are lower than those of traditional internal combustion engines. At idle and low speeds, they demonstrate superior comfort compared to traditional vehicles, with an energy consumption of only 15-20kwh per 100 kilometers.

What is the Principle of Hybrid Sedans?

Automobile hybrid principle: 1. Hybrid power: The discrete structure of the engine and motor evolves into an integrated structure combining the engine, motor, and transmission, known as the integrated hybrid powertrain system. Hybrid powertrains can be classified by power transmission routes into three types: series, parallel, and series-parallel. 2. Series power: Series power consists of three powertrain components: the engine, generator, and motor, forming an SHEV power unit system in a series configuration. The engine drives the generator to produce electricity, which is then delivered to the battery or motor via a controller. The motor drives the car through a transmission mechanism. Under light loads, the battery drives the motor to power the wheels, while under heavy loads, the engine takes over. 3. Motor-generator drives the motor: When the vehicle is in start-up, acceleration, or climbing conditions, the engine, motor-generator set, and battery pack jointly supply power to the motor; when the electric vehicle is in low-speed, coasting, or idle conditions, the battery pack drives the motor. When the battery pack is low on power, the engine-generator set charges the battery pack. The series structure is suitable for frequent starts and low-speed conditions in urban areas.

What Causes Car Shaking When Accelerating?

The causes of car shaking during acceleration are as follows: 1. Fuel system issues: Fuel system problems are usually caused by clogged fuel lines, leading to poor fuel supply, manifested as engine shaking, unstable idling, or stalling while driving. Additionally, fuel pump failure can also cause engine shaking. To diagnose fuel pump issues, disconnect the fuel line and check the flow rate and volume. 2. Electrical system issues: Check if the ignition timing is accurate, as irregular ignition is often a timing issue. Inspect whether the spark plugs have aged, if the gaps are uniform, and if the gaps have changed. Furthermore, malfunctioning of the distributor can also lead to engine shaking. 3. Mechanical reasons: Check the engine's operating condition for any abnormal sounds, such as valve noises. Inspect the belt's working condition to see if it's loose.
