The top speed of an underbone motorcycle can reach around 100 km/h. The speed of an underbone motorcycle is generally more suitable at around 40-50 km/h, which is also the economical speed for this type of motorcycle. High-end underbone motorcycles can reach a top speed of approximately 100 km/h. Top speed testing: The top speed is the maximum driving speed a vehicle can achieve under windless conditions on a level, good-quality asphalt or concrete road. According to Chinese regulations, the last 500 meters of a 1.6-kilometer test section are used as the top speed testing area, with four round trips conducted, and the average is taken. Limiting top speed: The top speed is different from the theoretical maximum speed (which refers to the best performance the engine can achieve under optimal conditions, limited to theory only). For some high-performance vehicles, manufacturers often limit the vehicle's top speed through technical means (such as electronic speed limit functions) to protect the engine or comply with traffic regulations when the vehicle leaves the factory.

Do I Need to Make an Appointment for Subject One?

Subject One requires an appointment. Driving schools usually help students make appointments, but students can also book the Subject One exam online themselves. Any subject can be scheduled through the Comprehensive Traffic Safety Service Management Platform or the Traffic Management 12123 mobile app. After successfully scheduling Subject One, you will receive an SMS reminder 3-5 days before the exam. Even if the appointment fails, you will be notified via SMS. If the Subject One appointment is unsuccessful, simply choose an earlier-ranked session and reschedule. After making an appointment for Subject One, you only have two exam attempts. If you fail the first exam, you can retake it once. If you still fail the second time, you will need to reschedule. Upon passing the Subject One exam, you will receive a Learning to Drive Certificate. With this certificate, you can proceed to take the exams for Subject Two, Subject Three, and Subject Four. However, note that the Learning to Drive Certificate is valid for a limited time, usually three years. You can cancel the appointment application before the deadline. If the appointment is successful but you need to cancel the exam, you must go to the vehicle management department to complete the cancellation procedure. Otherwise, it will be considered an absence, resulting in a failing grade. Important notes for the Subject One exam: Arrive at the exam venue early or on time, and enter with your ID card and exam voucher. Sit in the assigned seat number. The exam room has cameras that capture your face throughout the test, so ensure your entire face is visible. Avoid covering your face with hair, hands, scarves, or clothing, as this may result in disqualification.
