Columbus, OH – The U.S. Trotting Association has added three new chart comment abbreviations to give racing officials the ability to provide more precise detail in documenting incidents during a race while providing greater detail and transparency for participants, handicappers and fans.

The new abbreviations that are being added to charts and program pages are:

• DI – Driver Caused Interference
• RG – Rough Gaited
• OG – Off Gate (prefix code used to indicate a horse was off the starting gate at the start)
