How Long Does It Take to Get the Driver's License After Passing Subject Four?

After passing Subject Four, you will receive the license on-site, usually within about 2 hours. Subject Four, also known as the Subject Four theoretical test or driver's theoretical test, is part of the motor vehicle driver's license examination. The main content includes: requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations such as tire blowouts, and knowledge on handling traffic accidents. The Subject Four test consists of 50 questions, primarily in the form of case studies, images, and animations, with a full score of 100 and a passing score of 90. After the implementation of the Ministry of Public Security's Order No. 123, the Subject Three test was divided into two parts: in addition to the road test, a safety and common sense test was added, commonly referred to as "Subject Four," which assesses "driving ethics." Since this test is conducted after Subject Three, it is commonly referred to as the Subject Four test. Officially, there is no Subject Four. Before the test, students can study traffic regulations through driver simulation test software on mobile or computer devices.

What is the difference between parallel imported cars and 4S store cars?

Differences between parallel imported cars and 4S store cars: 1. Different products: Parallel imports allow the purchase of overseas models not available domestically; buying from a 4S store only offers manufacturer-released China-spec vehicles. 2. If parallel imported cars do not comply with Chinese traffic regulations, modifications may be required, otherwise, it can be difficult to register them domestically; vehicles sold by 4S stores all comply with Chinese traffic regulations, can be registered normally, and are not restricted. Parallel imported cars, compared to China-spec cars, refer to genuine vehicles that are purchased directly from abroad by traders without authorization from the foreign car brand manufacturer and its general distributor in China, and then imported into China for sale. This channel runs parallel to the authorized distribution channel.

Is there a fine for motorcycle passengers not wearing helmets?

Motorcycle passengers not wearing helmets will be fined. Below is relevant information about motorcycle penalties: Regulations: Regardless of the type of car driving license the driver holds, they are not permitted to drive motorcycles, as no car driving license includes motorcycle models in its permitted vehicle types. The appropriate licenses for driving motorcycles are D, E, and F licenses. A D license allows driving all two-wheeled and three-wheeled motorcycles, an E license permits driving all two-wheeled motorcycles, and an F license is only for driving light motorcycles with engine displacements below 50CC. Penalties: Driving a motorcycle with a car driving license is considered driving a vehicle type not covered by the license, which is treated as unlicensed driving. Penalties may be appropriately mitigated according to the regulations for driving a motor vehicle without obtaining a license. Unlicensed driving can result in fines, a deduction of 12 points, and possibly detention for up to 15 days.

How Hot Does a Motorcycle Exhaust Pipe Get?

Motorcycle exhaust pipe temperatures typically range from 300-150°C, gradually decreasing from the front section to the tail end, with the highest temperatures exceeding 500°C. Relevant details are as follows: Exhaust: During normal riding at 60 km/h, the front section near the engine reaches around 300°C, while the middle section near the footrest is about 150°C. When climbing a long slope in 1st or 2nd gear for an extended period, the engine runs at high RPM with low speed, causing the front exhaust section to rise to approximately 500°C, the middle section to about 300°C, and the rear section to around 150°C. Engine: During operation, the high-speed movement of piston rings and gears generates significant friction, producing substantial heat expelled through the exhaust. The exhaust pipe heats up continuously during this heat transfer process. The thinner front pipe near the engine is hottest (about 300°C), while the thicker sections near the kickstarter are cooler (150°C). The rear section is around 80°C. When riding mountainous terrain in 1st or 2nd gear with engine RPM reaching 5500, the exhaust pipe near the engine may glow red, indicating temperatures up to 800°C, while the kickstarter area reaches at least 300°C.
