42 U.S. Code § 14171 - Motor vehicle theft prevention program
The motor vehicle theft prevention program developed pursuant to this section shall include a uniform design or designs for decals or other devices to be displayed by motor vehicles participating in the program.
The Attorney General may establish more than one set of conditions under which participating motor vehicles may be stopped. If more than one set of conditions is established, a separate consent form and a separate design for program decals or devices shall be established for each set of conditions. The Attorney General may choose to satisfy the requirement of a separate design for program decals or devices under this paragraph by the use of a design color that is clearly distinguishable from other design colors.
After the program has begun, the conditions under which a vehicle may be stopped if affixed with a certain decal or device design may not be expanded without the consent of the owner.
Any person who is in the business of renting or leasing motor vehicles and who rents or leases a motor vehicle on which a program decal or device is affixed shall, prior to transferring possession of the vehicle, notify the person to whom the motor vehicle is rented or leased about the program.
As a condition of participating in the program, a State or locality must agree to take reasonable steps to ensure that law enforcement officials throughout the State or locality are familiar with the program, and with the conditions under which motor vehicles may be stopped under the program.
 So in original. The period probably should be a dash.
