Which is More Difficult: Subject One or Subject Four?

Both subjects are theoretical exams. Subject One focuses on driving knowledge, while Subject Four emphasizes safety knowledge. The questions in Subject Four often do not require rote memorization; correct answers can be deduced through practical reasoning. Subject One, however, includes more memorization-based content such as traffic police gestures and road sign markings. From this perspective, Subject One is relatively more difficult. Exam content for Subject One: Basic knowledge of motor vehicles; laws, regulations, and road traffic signals; fundamentals of safe and civilized driving; basic knowledge related to motor vehicle driving operations. Exam content for Subject Four: Requirements for safe and civilized driving operations; safe driving knowledge under adverse weather and complex road conditions; emergency handling methods for situations like tire blowouts; and post-accident handling knowledge.

Can a lost driver's license be used by others?

If a driver's license is lost, it could potentially be used by others for deducting points. However, legally, it is not permitted for someone to use a found driver's license to handle traffic violation points, as the license is strictly for the driver's personal use. If a lost license has been replaced with a new one, the lost license becomes invalid. Below are specific details about driver's licenses: Function: A driver's license is the legal document permitting a motor vehicle to be driven on the road, containing detailed information about the vehicle and its owner. Regulations: Drivers must operate a motor vehicle according to the vehicle type specified on their license and must carry both the driver's license and vehicle registration when driving. Driving without carrying a driver's license or vehicle registration will result in a 1-point deduction and temporary vehicle seizure until valid documents are provided.

How many people can a motorhome accommodate?

According to the standards of general small motorhomes, a motorhome can accommodate 4-6 people. However, if the length of the motorhome is less than 6 meters, the number of passengers must not exceed 6. Some motorhomes are also restricted to carrying no more than 5 people. The exact number of passengers allowed depends on the capacity indicated on the motorhome's certification. Below is relevant information: Introduction: Motorhomes are often referred to as 'homes on wheels,' combining the functions of both a house and a vehicle. However, their primary attribute remains that of a vehicle—a movable dwelling with home-like functionalities. Regulations: For trailer-type motorhomes, although they are not listed among the vehicle types prohibited from highways in the 'Road Traffic Regulations,' the 'Implementation Regulations of Road Traffic Safety Law' stipulate that 'small passenger cars are only allowed to tow travel trailers or trailers with a total mass of less than 700 kilograms, and trailers must not carry passengers.' Those that comply with this regulation are permitted on highways; otherwise, they are not allowed.
