When a car's transmission malfunctions, issues such as engine stalling when shifting gears, transmission lock-up, or failure to move after engaging a gear may occur. The transmission primarily refers to the vehicle's gearbox, which is divided into manual and automatic types. A manual transmission mainly consists of gears and shafts, achieving speed and torque variation through different gear combinations. An automatic transmission (AT) is composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system. The transmission is a crucial component in a vehicle, capable of altering the gear ratio to adjust the driving wheel's torque and speed. With advancements in modern technology, transmissions have evolved from manual to continuously variable transmissions (CVT) and from non-synchronized to synchronized systems, making operation increasingly convenient.

Will the passenger on a motorcycle be fined for not wearing a helmet?

The passenger on a motorcycle will be fined for not wearing a helmet. Below is relevant information about motorcycle penalties: 1. Relevant regulations: No matter what type of car driving license the driver holds, they are not allowed to drive a motorcycle. None of the permitted vehicle types for any car driving license include motorcycles. The driving licenses for 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 only allows driving light motorcycles with an engine displacement below 50CC. 2. Penalty measures: If someone drives a motorcycle with a car driving license, it is considered driving a vehicle type that does not match the permitted types of the driving license, which is equivalent to driving without a license. The penalty can be appropriately reduced according to the penalty regulations for driving a motor vehicle without obtaining a driving license. Driving without a license results in a fine, a deduction of 12 points, and may also lead to detention for up to 15 days.

What is the method for turning while driving a car?

The method for turning while driving a car is: 1. When turning, pass through the curve quickly to avoid generating excessive centrifugal force. Make full use of the width of the road and try to take a large, nearly straight arc when turning; 2. Before starting the turn, enter the curve from the outside of the curve, then move to the inside of the curve when reaching the middle; 3. After the car passes the apex of the curve, switch back to the outside of the curve and exit the curve along the outside. Choose the outside-inside-outside turning path. The principle of turning a car is slow entry, moderate throttle, and fast exit. Before entering the curve, maintain straight-line driving and first apply the brakes to slow the car down. For larger curves, further reduce the speed.
