FMVSS - Is There a Need for DOT Approval? - NHTSA

Tires - FMVSS 109 and 110

Another little bit of a tough concept. The DOT doesn't actually approve vehicles or equipment. They set the standards, and guidelines, the manufacturers certify their FMVSS items meet those standards.

DOT does not approve any motor vehicles or motor vehicle equipment items as complying with all applicable FMVSS. That is instead the responsibility of the vehicle or equipment item's original manufacturer.

Ferrari FMVSS label

 For motor vehicles, the certification is provided in the form of a label that is permanently affixed to the vehicle by its original manufacturer, stating that the vehicle complies with all applicable FMVSS in effect on its date of manufacture. For vehicles other than motorcycles or trailers, the label must be affixed to either the hinge pillar, the door latch post, or the door edge that meets the door-latch post, next to the driver's seating position. For motor cycles and motor driven cycles, the label must be affixed to a permanent member of the vehicle, as close as is practicable to the intersection of the steering post with the handlebars, so that it is easily readable without moving any part of the vehicle except for the steering system. For trailers, the label must be affixed to a location on the forward half of the left side of the vehicle, so that it can be easily read without moving any part of the vehicle.
