Motorcycle Safety & Driveability: Safety chains on bike, motorcycle, trailer

Question
Is it a law in MN to have safety chains on your motorcycle if you are pulling a small trailer?  We had a hitch put on our bike for pulling our small trailer, and they didn't put safety chains on the hitch. Our last bike hitch had them and we thought it was a law.  Thank you

Answer
Apparently it is the law. According to MSS169.82 Sub 3:

Subd. 3. Hitch, chain, or cable. (a) Every trailer or semitrailer must be hitched to the towing
motor vehicle by a device approved by the commissioner of public safety.
(b) Every trailer and semitrailer must be equipped with safety chains or cables permanently
attached to the trailer except in cases where the coupling device is a regulation fifth wheel and
kingpin assembly approved by the commissioner of public safety. In towing, the chains or cables
must be attached to the vehicles near the points of bumper attachments to the chassis of each
vehicle, and must be of sufficient strength to control the trailer in the event of failure of the towing
device. The length of chain or cable must be no more than necessary to permit free turning of the
vehicles. A minimum fine of $25 must be imposed for a violation of this paragraph.
(c) This subdivision does not apply to towed implements of husbandry.
(d) No person may be charged with a violation of this section solely by reason of violating a
maximum speed prescribed in section 169.145 or 169.67.

For what I can see, motorcycle trailers are NOT exempt from this law.
