How often must vehicle inspections be performed?

Vehicle inspections are crucial for maintaining safety and ensuring that a vehicle meets the required standards set by authorities. In Puerto Rico, the regulation states that vehicle inspections must occur every 6 months to a year. This frequency helps identify any mechanical issues that could pose safety risks or lead to environmental concerns due to emissions. Regular inspections are part of maintaining the vehicle's registration and ensuring it is roadworthy.

The options that suggest inspections every month or only upon purchasing a used car do not align with the established regulations, as they either propose unrealistic frequency or only apply to specific situations rather than ongoing vehicle upkeep. Additionally, inspections every two years may not be sufficient for the overall safety monitoring that more frequent inspections provide.
