Most challenging aspects associated with introducing and passing interlock legislation:
It is difficult to draft bills, make changes, and introduce legislation. There is a very long process each bill has to go through because there are proposals, approval, and the need for a certain number of legislators to back a bill. It often takes 3-5 years for a bill to be passed, which sometimes means it is outdated by the time it is passed. It took nearly seven years for the rules and regulations to be introduced. Also, Public Safety is only allowed to promote two-three bills each year, and there are competing priorities. The main pushers for interlock legislation are the manufacturers.
