How frequently must vehicle registration be renewed in the CNMI?

Vehicle registration in the CNMI must be renewed annually. This requirement is in place to ensure that vehicles on the road remain properly registered and up to date with local regulations. Renewing vehicle registration annually allows for the assessment of vehicle compliance with safety and emissions standards, ensuring that only roadworthy vehicles are permitted to operate in the territory. An annual renewal also helps local authorities maintain an updated record of all registered vehicles, which can assist in law enforcement, taxation, and planning public services.

The other options suggest longer intervals for renewal, which do not align with the regulatory framework established in the CNMI for maintaining vehicle registrations and ensuring public safety.
