When does the highway toll-free period refer to?

Highway toll-free time refers to the time when you exit the highway. Below is relevant information about highways: 1. Sign introduction: Highway signs typically feature an overpass symbol between two roads. The background color of the sign varies depending on different countries and regions. Mainland China, Taiwan China, South Korea, the United States, Canada, Japan, Switzerland, etc., use a green background. 2. Classification: Roads are divided into five categories based on their usage tasks, functions, and traffic volume: highways, first-class roads, second-class roads, third-class roads, and fourth-class roads. Highways are trunk roads exclusively designed for automobiles to travel in separate directions and lanes with full access control.

Can upgrading the ECU improve car performance?

Upgrading the ECU can improve car performance. Here is relevant information about ECU upgrades: 1. Introduction: (1) Remove restrictions. There was originally a maximum limit where the car couldn't exceed certain speed or power levels. Removing this limit allows for greater performance. (2) Change air-fuel ratio. When the car operates, the engine mixes air and fuel which ignites to produce power. Adjusting this ratio affects performance. 2. Risks: (1) Increased carbon buildup. Most domestic ECU tuning manufacturers lack proper engine calibration capabilities. They simply overwrite existing installation packages or data files for direct upgrades. Without proper coordination with other components, this easily leads to carbon buildup. (2) Increased fuel consumption. With improved performance, fuel consumption also increases.

How to Learn Driving for People with Poor Car Sense?

People with poor car sense should build confidence, stay diligent, and not get discouraged, taking steady and solid steps. Below is relevant information about car sense: 1. Methods: (1) Master the correct driving posture. Comfort is key when driving, so the first thing a learner should do after getting in the car is to adjust the seat position. The front and back distance of the seat should be adjusted so that the left foot can press the clutch pedal all the way down with ease. During the process of pressing and releasing the clutch, the right hand can adjust the seat forward or backward based on comfort until satisfaction is achieved. (2) Rearview mirrors are crucial. Rearview mirrors act as the driver's "third eye," providing additional safety while driving. During the driving test, learners need to adjust the rearview mirrors to obtain a better view of the rear. 2. Operation: Beginners are advised to first study theory before getting behind the wheel. Only by memorizing the basic operational methods theoretically can they develop correct operational habits in practice. Continuous practice and summarization will help cultivate the right car sense over time.

Is the original insurance still valid after changing the vehicle license plate?

If the license plate is changed without updating the insurance accordingly, the insurance becomes invalid. When changing the license plate, it is essential to promptly contact the insurance company to update the insurance details. Below are two scenarios for changing the license plate: 1. Both the license plate and vehicle owner are changed: If both the license plate and the vehicle owner are changed, it is necessary to bring all the documents related to the sale and transfer, including the vehicle registration certificate, transfer invoice, original insurance policy, and it is preferable for both the original owner and the new owner to be present with the insured vehicle to complete the insurance transfer procedures at the insurance company. 2. Only the license plate is changed, the owner remains the same: If only the vehicle license plate is changed, you only need to contact the previous insurance agent after obtaining the new vehicle registration certificate, who is obligated to handle the relevant change procedures. Below is an introduction to car insurance: Car insurance is a type of commercial insurance that covers liability for personal injury or property damage caused by natural disasters or accidents involving motor vehicles. Its primary clients are legal entities or individuals who own various types of motor vehicles.

What's the difference between 5w30 and 5w40 engine oil?

The differences between 5W-30 and 5W-40 engine oils are as follows: 1. Different viscosity: 5W-30 and 5W-40 oils have different viscosities, with 40 being slightly higher. This means that 40 has higher fuel consumption. 2. Different performance at low temperatures: 5W-30 performs better in low-temperature conditions. This is because the viscosity of 5W-30 is significantly better than that of 5W-40 in low-temperature conditions. 3. Different performance at high temperatures: Under high-temperature conditions, 40 offers better stability. Therefore, if working under prolonged high-temperature conditions, 40 is preferable. For example, in summer, but it should be clarified that even in the hottest summer at the equator, the high-temperature characteristics of 5W-30 are sufficient.

Do vehicles over 6 years old need to undergo an inspection?

Vehicles over 6 years old need to undergo an inspection. Below is the relevant information about the inspection: 1. Introduction: (1) 6-year exemption from inspection ≠ no inspection for 6 years. The 6-year exemption from inspection only applies to new vehicles within 6 years, exempting them from on-site inspection. This means that within 6 years from the date of vehicle registration, you still need to apply for an inspection mark every 2 years. (2) The 6-year exemption does not include the 6th year. For vehicles over 6 years old (including the 6th year), an annual inspection is required. Therefore, by the 6th year, the vehicle needs to undergo an annual inspection. 2. Regulations: (1) Small and micro non-operational vehicles must be inspected every two years within the first 6 years, and those meeting the exemption criteria can directly apply for an inspection mark. Starting from November 20, 2020, non-operational small and micro passenger vehicles (excluding minivans) over 6 years but under 10 years old will have their inspection cycle relaxed from once a year to once every two years. This means private cars only need to undergo two on-site inspections within 10 years, specifically in the 6th and 8th years. (2) Operational passenger vehicles must be inspected once a year within the first 5 years, and every 6 months after 5 years.
