What is required for cars manufactured in 1967 or later concerning air pollution?

Cars manufactured in 1967 or later are required to be equipped with an exhaust emissions system to meet environmental standards aimed at reducing air pollution. This requirement is part of regulations established to control the amount of harmful emissions that vehicles release into the atmosphere. The exhaust emissions system is designed to filter and manage the gases produced by a vehicle's engine, helping to minimize pollutants such as carbon monoxide, nitrogen oxides, and hydrocarbons.

By ensuring modern vehicles have these systems in place, the goal is to promote cleaner air and support public health initiatives. This requirement applies to all vehicles, regardless of whether they are gas-powered or alternative fuel vehicles, thus maintaining a consistent standard for emissions control across the board.

Other options do not align with the regulations; for instance, vehicles manufactured in 1967 or later cannot be exempted from having an emissions system, nor can they only undergo a visual inspection without the necessary functional requirements. The option suggesting that vehicles must be electric or hybrid also does not reflect the regulations, as conventional gas vehicles may also comply with emissions standards if they have the appropriate systems installed.
