“...All horses require a safety inspection, for which fees apply, as assessed by the recipient of the fees. All horses must also get an emissions inspection, for which additional fees apply. In some locales these inspections are required every 12 months. Both inspections are also required when the ownership of a horse is transferred. For your convenience, lame or dead horses are commonly exempt from emissions inspections: Check with local officials to ensure compliance.
In some areas, both inspections may done at the same time by a certified inspector at privately owned inspection stations that pay applicable fees to the Department of Horses. Please be aware, the emissions inspection process will include the insertion, by a state-certified technician, of a gas-sniffing probe into the rear end of your horse.”
