Less than week after a double-decker trailer rollover caused the death of 17 horses, a member of the Illinois General Assembly introduced legislation that would ban the use of such trailers to transport horses for any reason.

Ill. State Rep. Robert S. Molaro (D-25th) introduced HB4166 on Nov. 2.

The measure amends section 5 of Illinois’ Humane Care For Animals Act, adding: “No person may transport any equidae in any vehicle or trailer containing two or more levels of equidae, one on top of another.”

If passed, the law carries Class B misdemeanor penalties for the first offense, increasing to a Class 4 felony for second or subsequent offenses. The law would be come effective immediately after its passage by the full General Assembly
