Re: New Diesel Fuel Discount Card Program Reply #300 – September 10, 2020, 10:29:10 am I got an email about the new TSD Open Roads mobile app yesterday. Replied to the email and awaiting an invite to download the new app. The email says they are limiting registration to 500 each day to prevent the website from crashing. Anyone else get the same? if so, how is the new app?
