What does 9AT mean in cars?

9AT in cars refers to an automatic transmission with 9 forward gears. The 9AT transmission controls different combinations of planetary gears through shifting components, achieving a setup of 9 forward gears and 1 reverse gear. The advantages of 9AT include fuel efficiency and faster acceleration, while the disadvantages are higher cost and complex structure. There are four types of automatic transmissions: hydraulic automatic transmission, CVT continuously variable transmission, dual-clutch transmission, and automated manual transmission. Using an automatic transmission makes vehicle operation more convenient. The core function of an automatic transmission is to achieve automatic gear shifting, meaning that while driving, the driver operates the accelerator pedal as needed, and the automatic transmission can automatically shift into different gears based on engine load and the vehicle's operating conditions.

Is it still necessary to display the vehicle insurance decal?

It is still required to display the vehicle insurance decal. Compulsory Traffic Insurance (CTI) is a mandatory insurance for vehicles, and the insurance decal must be affixed to the upper right corner of the front windshield. However, starting from 2018, pilot areas in Beijing no longer require physical insurance decals on vehicles, replacing them with electronic insurance policies. Vehicles that have already obtained license plates and registration certificates must display the annual inspection decal. Annual vehicle inspections are a mandatory check-up conducted every year to ensure driver safety. These inspections help identify hidden hazards that are not usually visible and remind drivers to perform timely maintenance, enhancing safety awareness and protecting driving safety, thereby reducing the occurrence of traffic accidents.
