Is it mandatory to display the motor vehicle inspection compliance sticker?

Nowadays, the annual vehicle inspection sticker has been digitized and no longer needs to be physically displayed on the vehicle. Below is relevant information about vehicle inspections: 1. During the inspection, tailpipe emissions will be tested for compliance: Vehicle emissions testing involves the oxygen sensor and catalytic converter. Their optimal operating temperature ranges between 400 to 800 degrees Celsius, so it's recommended that owners warm up their vehicles in the inspection area before the emissions test to increase the pass rate. 2. Clean your vehicle: Prior to the annual inspection, owners should thoroughly clean their vehicles. Cleaning the body, engine compartment, and chassis in advance facilitates the inspection process for technicians and improves the chances of passing. 3. The vehicle management office will inspect the vehicle's lighting: If the vehicle's lights are found to be either too dim or too bright, it will be deemed non-compliant and fail the inspection. It's advisable to restore the headlights to their original condition before the inspection to ensure compliance.
