Regarding the side guards that were used for the tests, unfortunately I don't recall exactly where we sourced those from, but I can definitely follow up with that information after the meeting.
The work we did in this regard was, again, in response to a direct request we received from the regulator that holds the responsibility for the Canadian motor vehicle safety standards, Transport Canada. This was in response to their desire to understand if these side guards would meet a variety of different questions they were looking to answer.
If I recall, there was a slight issue in that we observed an increased temperature on the braking system, though. The reduction of airflow over the brakes had to be looked at as well, as part of the overall possible implementation of side guards on trailers. I can follow up on that if you would like.
