You pretty much have to have a copy of the Traffic Safety Act with you to compare how things are with the proposed changes.
And here's the transcript of Bill 49's introduction:
    Traffic Safety Amendment Act, 2007
    Mr. Johnston: Thank you, Mr. Speaker. I request leave to intro-duce    
 Bill 49
Bill 49
, the Traffic Safety Amendment Act, 2007.
    The bill will amend the Traffic Safety Act. Amendments are
    required as part of Alberta’s traffic safety plan. Legislative amend-ments    will define an intersection safety device which can be used to    gather evidence dealing with red light and speeding infractions at    intersections and the introduction of this evidence in court by    affidavit – these changes will incorporate and mirror existing    provisions for red-
    light cameras – and also allow photocopies of
    registrations for class 4 commercial trailers to be carried as an option    to the original certificate.
    The proposed legislation will affect evidence considered by the    Alberta Transportation Safety Board respecting alcohol-
    related
    driving. It will also streamline the process of applying for a court    review of board decisions and confirm the amount of deference the    court gives to board decisions.
    Finally, the legislation includes a liability cap for the vehicle    leasing and sale industry and lenders who retain title to vehicles as    collateral for loans where these businesses do not have possession of    the vehicle.
    Thank you, Mr. Speaker.
