Minnesota Statutes Transportation (Ch. 160-174A) § 169.73. Bumpers, safeguards

Subdivision 1. Definitions. (a) As used in this section, “private passenger vehicle” means a four-wheeled passenger automobile as defined in section 168.002, subdivision 24; a van as defined in section 168.002, subdivision 40; a pickup truck as defined in section 168.002, subdivision 26; and a jeep-type automobile or other multipurpose vehicle. “Private passenger vehicle” does not include a collector vehicle or collector military vehicle as defined in section 168.10.

(b) “Suspension system” includes both the front and rear wheels and tires of a vehicle as specified in subdivision 3.
