For a vehicle to pass inspection, how must the transmission function?

The requirement that all functions—Drive, Reverse, and Park—must be operational ensures that the vehicle can be safely operated in all necessary driving conditions. Each function serves a specific purpose: Drive allows the vehicle to move forward, Reverse enables movement backward, and Park secures the vehicle when stationary.

If any of these functions were not operational, it could create safety hazards for the driver and others on the road. For instance, a malfunctioning Reverse would prevent a driver from being able to back out of parking spaces or navigate tight areas, while a malfunctioning Park could lead to unintentional vehicle rollaway, posing a significant risk.

In conclusion, operational safety is paramount, and the requirement for all three functions to be in working order reflects a standard that promotes safe vehicle operation.
