Is there a chance this traffic voilation will be dismissed in court?

Trying to offer a friend some advice, hopefully you guys can help.

My friend was involved in an accident about a month back were she apparently rolled through a stop sign at a 4 way intersection and collided with a driver on the opposite side. She admitted fault at the accident which was obviously a mistake on her part, but she was shaken up and perhaps a bit overly apologetic for the whole thing. She was charged for failure to stop and expired plates.

Subsequently, the other driver was charged with DWI and arrested at the scene. Its unknown if his impairment contributed in any way to the accident, but to me if he perhaps wasn't drunk he could have reacted better and avoided the collision. Heck, he shouldn't even have been on the road in the first place.

She's prepared to accept responsibility but is hoping perhaps the judge will drop a charge, or just throw the whole thing out possibly. The cop was at the scene may not even show up, who knows.

She has no attorney and will be going to court tomorrow, how should she plea to this? How should be approach the judge in this situation?

Thanks.
