What is the determining factor for renewing a vehicle's motor vehicle registration?

The determining factor for renewing a vehicle's motor vehicle registration is the last digit of the plate number. This system is structured to ensure that vehicle registrations are scheduled and processed in an organized manner throughout the year. By using the last digit, the Land Transportation Office distributes the registration renewal workload evenly over a set periodic cycle, which helps in reducing congestion and bottlenecks at registration offices.

The other options, such as the middle digit, first digit, or vehicle color, do not play a role in the renewal schedule. The middle and first digits do not correlate with any systematic renewal process recognized by the LTO, and the color of the vehicle is also irrelevant to the registration renewal timeline. This organization and clarity help vehicle owners understand when they need to renew their registration based on the last digit of their plate number.
