What identification label must be affixed to a specially constructed vehicle for inspection?

A specially constructed vehicle must have a Referee Label affixed to it for inspection purposes. This label is important because it provides specific information regarding the vehicle's compliance with emission and safety standards. The Referee Label is issued after a thorough inspection by a designated referee station, which verifies that the vehicle meets the necessary regulations.

This label indicates to inspectors and law enforcement that the vehicle has gone through the appropriate evaluation process and has been approved for use on public roads. Additionally, it helps in documenting modifications made to the vehicle, ensuring that any alterations comply with state laws regarding emissions and safety.

The other options refer to different types of labels or stickers that serve other purposes. The Manufacturer's Label is typically found on vehicles manufactured by established manufacturers, providing essential information such as the vehicle's specifications. The Inspection Sticker indicates that a vehicle has passed its regular smog check but is not specific to specially constructed vehicles. The Custom Vehicle Identifier is not a standard term used in this context. Thus, the Referee Label is the correct identification required for specially constructed vehicles.
