Legal advice on DUI traffic stop

So myself and few friends were out having a few drinks Beer only for me They were having shots after a hour and half I relized they were getting a little sloppy so I told them I’d get them back to there hotel so I could be on my way back to mine for the night . Well we were headed to there hotel when we all noticed a police officer was about to pass us and of course they was all nervous and noticed that he or she was turning around so we pulled into a drive way and shut the car off and exited the vehicle before the police officer got turned around and up to us. Once they did come up to us they never turned on there lights nor asked for identification or drivers lisc insurance or anything only that they had a 911 call of a possible person driving under the influence and asked if i had been drinking and if I would take a field sobriety test I said no and was immediately handcuffed for refusing never was I told of any rights I was escorted to there jail and asked to take another type of test which I declined because still I didn’t believe or understand why they even were questioning me So they signed a big Refused across a refusal form which they never signed warrant for my blood was

Charged with first offense DUI with a bac of .19%. No criminal history not even a speeding ticket since 1992. The night of the incident I received a call from a friend in need of a ride to get out of a domestic violence situation immediately. Just getting off work less than an hour prior I had a few drinks with no intention of driving. Living in a very rural area, the time of night, her not knowing many people close by, knowing her situation, I chose to give her a ride from where she lived to a hotel, about 15 miles all together. I was stopped for my Farm Use tag and it being so late at night (wasn't thinking about it at the time), the officer was very understanding seeing all of her belongings in the vehicle in trash bags, including her dog. The officer of course having to do his job had to charge me with me blowing well over the limit but stated how he felt about the circumstances and how he understood why I did drive. I was coherent and cooperative and released within an hour and a half. The officer also stated that he would make sure to speak on my behalf in court. With my BAC being so high is there any chance I could get the charge reduced?
