What to do about a OWI resulting in felony charges?

Has your friend been assigned an attorney in this matter?  She is entitled to one and she needs to request one as soon as possible. Have you attempted to post bail?  You can post a bond for a percentage of the bail that has been set.  States have really cracked down on driving under the influence cases and repeat offenders can indeed be charged and jailed the same as hard core felons.  But operating a weapon the size of a car without the full use of your senses about you, well, you can understand  why.  Lucky for her that the other person was fine.  She could be facing vehicular manslaughter charges.  How this will all pan out depends on many factors and only her attorney can give that advice comfortably.  Get help.
