The Commissioner may charge a fee of $125 per vehicle, for the examination, verification, or identification of the serial or identification number of any vehicle, motor vehicle, trailer, or semitrailer. The Commissioner may also receive applications for the issuance of an identification number and investigate the circumstances of the application. When the Commissioner is satisfied that the applicant is entitled to the identification number, the fee for the issuance of such identification number shall be five dollars. If any inspection under this provision is done at the same time as an inspection under § 46.2-1605, then only one $125 fee shall be charged for both inspections. All fees collected under this section shall be paid by the Commissioner into the state treasury and set aside as a special fund to be used to meet the expenses of the vehicle identification number and salvage vehicle inspection program.
