The owner of each snowmobile requiring numbering by this State shall file an application for number with the Department on forms approved by it. The application shall be signed by the owner of the snowmobile and shall be accompanied by a fee of $30. When a snowmobile dealer sells a snowmobile the dealer shall, at the time of sale, require the buyer to complete an application for the registration certificate, collect the required fee and mail the application and fee to the Department no later than 15 days after the date of sale. Combination application-receipt forms shall be provided by the Department and the dealer shall furnish the buyer with the completed receipt showing that application for registration has been made. This completed receipt shall be in the possession of the user of the snowmobile until the registration certificate is received. No snowmobile dealer may charge an additional fee to the buyer for performing this service required under this subsection. However, no purchaser exempted under Section 3-11 of this Act shall be charged any fee or be subject to the other requirements of this Section. The application form shall so state in clear language the requirements of this Section and the penalty for violation near the place on the application form provided for indicating the intention to register in another jurisdiction. Each dealer shall maintain, for one year, a record in a form prescribed by the Department for each snowmobile sold. These records shall be open to inspection by the Department. Upon receipt of the application in approved form the Department shall enter the same upon the records of its office and issue to the applicant a certificate of number stating the number awarded to the snowmobile and the name and address of the owner.
For the registration years beginning on or after January 1, 2017, the application shall be signed by the owner of the snowmobile and shall be accompanied by a fee of $45.
