What vehicles are specifically mentioned as needing semi-annual inspections?

School buses and vehicles for mass transit are specifically mentioned as needing semi-annual inspections because these vehicles are integral to public safety and transportation. Ensuring these types of vehicles are in optimal condition is crucial, given that they carry multiple passengers regularly and must adhere to strict safety standards. Regular inspections help identify and rectify any potential safety issues, thus protecting both the drivers and the public.

In contrast, the other vehicle types listed do not have the same requirement for semi-annual inspections. Personal vehicles typically undergo annual inspections, while antique vehicles may have different regulations depending on their status and use. Electric vehicles also follow the standard inspection timeline unless stated otherwise, reflecting the evolving standards as technology changes. Each category serves a distinct purpose within the transportation system and is regulated appropriately based on risk and usage frequency.
