The first charge, that was dismised by a judge, occured in June 2005.
The second two charges occured in August 2006 and December 2006. Both ended up being first time offenses by virtue of guilty plea, as mentioned above. As I result my friend got one year of unsupervised probation (180 days of 100% suspended jail time per each DUI) which is still ongoing, ASAP classes that have been completed and fines/costs which have been paid.
As far as other record goes, each DUI charge came with refusal charge, and each refusal charge has been dropped. Also, the prosecution was pushing my friend to enter a guilty plea to the August 2006 DUI (since the had absolutely no evidence, no field tests or BAC) by threatening him to get indicted for an assault on a cop (who alleges he was spat on) if he refuses to do so. He refused at the advice of his attorney because he knew he did not spit on a cop, the cop never got a warrant regarding this, also the attorney was going to fight the charge based on vindictive persecution. So he was indicted on an assault on a cop by a grand jury, which is not a surprise since they indict everyone. Then my friend changed his mind since he got tired of courts and pleaded guilty to the first time DUI, and the prosecution dropped the assault charge.
My friend has been in the country since 1999 without any convictions until March 6, 2007. He's been married, no kids, divorce is about to be final. 2005/2006 was a bad period since he's been going through divorce and bankruptcy. Things have improved significantly in his life since.
