is there any for minnesota? Subd. 4.Maximum bumper height. (a) Notwithstanding the restrictions contained in subdivision 3, bumpers required under this section shall not exceed a height of (1) 20 inches on any passenger automobile or station wagon or (2) 25 inches on any four-wheel drive multipurpose type vehicle, van as defined in section 168.002, subdivision 40, or pickup truck as defined in section 168.002, subdivision 26, when the vehicle is being operated on a public highway. The height of the bumper shall be determined by measuring from the bottom of the bumper, excluding any vertical bumper attachments, to the ground. A vehicle which has an original bumper which does not exceed a height of 30 inches may be modified by attaching a full width bumper to the regular bumper to meet the height requirement. The attached bumper must be at least 4.5 inches in vertical height, be centered on the vehicle's centerline, extend at least ten inches on either side of the frame, and be attached to the frame in at least four places with angle braces at no less than 45 degrees so that it effectively transfers impact to an extent equal to or greater than the original bumper. thats all i could find considering ride height.
Yep, they have height laws but none I've ever seen for low. Cali on the other hand has laws regarding drops, defined as a minimum safe height for headlights.
I made a post to start laying out some laws in MN http://www.mngaragegeeks.com/forum/threads/1565-MN-It-s-the-Law!-(Vehicle-Equipment-Laws
