What is the speed limit for light trucks on highways?

Blue-plate light trucks have a speed limit of 100 km/h on highways, with a minimum speed not lower than 60 km/h. Highway speed limit values: The highway speed limit shall not exceed 120 km/h, and the limit value should be an integer multiple of 10 km/h. The difference between speed limits of two adjacent sections should not exceed 20 km/h. For highway interchanges, the speed limit difference between mainlines, deceleration lanes, and exit ramps should not exceed 30 km/h. Speed limit sign design: Speed limit signs should be designed to be more concise, clear, and aesthetically pleasing. They should be installed at the starting point of speed-limited sections without being obstructed by roadside trees, structures, or other traffic signs, and should be repeated as needed.

Can you change lanes on a double yellow dashed line?

Double yellow dashed lines allow lane changes. Here are the relevant details about yellow dashed lines: 1. Lane change indication: Dashed lines indicate that crossing is permitted, meaning lane changes are allowed. When encountering yellow dashed lines on the road, as long as you're in the dashed line area and obeying traffic signals and yielding rules, U-turns or lane changes are permitted. 2. Follow road markings: This not only reduces accidents but also improves traffic efficiency. Always obey road markings to create a healthier and more efficient driving environment. Remember one key point: Never cross if your side has a solid line; if your side has a dashed line, crossing is permitted.

What is the difference between red and green transmission fluid?

The difference between red and green transmission fluid lies in their composition. In addition to its lubricating function, automatic transmission fluid (ATF) also enables gear shifting in automatic transmissions through hydraulic pressure. Therefore, it is necessary to replace the transmission fluid regularly. Excessive usage time or mileage can cause the fluid to deteriorate, reducing its lubricating effectiveness, which may lead to internal component wear and affect the gear shifting performance of the automatic transmission. Below is an introduction to transmission fluid: 1. Depending on the transmission structure, transmission fluid is divided into automatic transmission fluid and manual transmission fluid. 2. Automatic Transmission Fluid (ATF): ATF is specifically designed for automatic transmissions. Early automatic transmissions did not use dedicated fluid but instead relied on engine oil. Due to significant differences in operating conditions and technical requirements, this practice was quickly phased out. Modern ATF serves as both the hydraulic fluid for torque converters and the lubricant for planetary gear structures and shifting mechanisms. Under normal driving conditions, ATF should be replaced every 120,000 kilometers, while under severe driving conditions, it should be replaced every 60,000 kilometers. 3. Manual Transmission Fluid: Commonly referred to as gear oil, it is categorized into five grades (GL-1 to GL-5) by the American Petroleum Institute (API) based on quality. GL-1 to GL-3 have lower performance requirements and are used for lubricating spur and bevel gears under general loads, as well as transmissions and steering gears. GL-4 is used for high-speed, low-torque and low-speed, high-torque conditions, such as in hypoid gear drive shafts and manual transmissions. GL-5 offers the highest performance level and is used for hypoid gear drive shafts and manual transmissions under harsh operating conditions with high shock loads. Under normal driving conditions, manual transmission gear oil should be replaced every 2 years or 60,000 kilometers.

How Old Do You Need to Be to Ride a Motorcycle?

Individuals aged 18 to 60 can apply for a motorcycle driver's license, and only after obtaining the license can they ride a motorcycle. Tricycle Motorcycles: For tricycle motorcycles with an engine displacement greater than 50ml or a maximum design speed exceeding 50km/h, a Class D license is required. Two-Wheeled Motorcycles: For two-wheeled motorcycles with an engine displacement greater than 50ml or a maximum design speed exceeding 50km/h, a Class E license is required. Displacement of 50ml or Less: For motorcycles with an engine displacement of 50ml or less and a maximum design speed of 50km/h or less, a Class F license is required.

What is the difference between dual throttle cables and single throttle cables?

Here are the differences between dual throttle cables and single throttle cables: 1. Number of throttle cables: In a single cable setup, there is only one throttle cable under the right-hand throttle grip. In a dual cable setup, there are two throttle cables under the right-hand throttle grip. 2. Throttle control precision: Dual throttle cables provide more precise throttle control compared to single cables. The throttle return effect is also better with dual cables. 3. Usage differences: Constant vacuum carburetors often use dual throttle cables, while slide carburetors typically use single throttle cables. Although there are these differences between single and dual throttle cables, in practical use, there is no significant difference. Therefore, replacing dual cables with a single cable will not have any adverse effects.

What is a Sunroof Ice Armor?

Sunroof Ice Armor is a product derived from the combination of car wraps and heat insulation films, using TPU as its base material. It functions as a protective film applied externally to vehicles, offering features such as UV blocking, heat insulation, and scratch self-repair. Below are details about Sunroof Ice Armor: 1. Definition: Sunroof Ice Armor is a functional protective film for external vehicle application, based on TPU and evolved from car wraps and heat insulation films, providing UV blocking, heat insulation, and scratch self-repair capabilities. 2. Functions: It blocks 99% of UV rays, 90% of infrared rays, and also cushions the impact of external forces on the sunroof. 3. Precautions: Essentially, Sunroof Ice Armor is an invisible car wrap. If applied to the windshield, there may be issues such as the wipers not moving smoothly or scratching the film. For side windows, problems like the window not descending smoothly or even potential motor burnout may occur.
