The easy answer to your question is, yes, you can always do jail time. No judge will tell you that you cannot go to jail. Most Harris county judges will give you more jail time than you would probably want to do though. A revocation of your probation would also involve suspension of your license for probably a year. Then you have to get an occupational license and SR22 and all of the expenses that follow that.
No judge in Harris county will want to lock you up over financial problems....
You need to tell the insurance about the accident in order to file a claim. You do not need to admit anything to them about drinking or being intoxicated. The DA can subpoena any statement you make to your insurance. Get representation ASAP for specific advice on dealing with your insurance and the DA.
Tough situation you are in. People with felony records can get jobs. If your case is only pending, I would like to think it wouldn't hurt you so much. Maybe try a different area of employment. It may require considering a different pay range than you are used to.
You will find fee ranges from hundreds of dollars to the tens of thousands of dollars. Good lawyers are not cheap. Our time is very valuable to us, our other clients, and our families. Think about how much time and effort you hope your lawyer will spend on your case. Think about how much you would want to make if you were very good at what you do, and call some local lawyers who you can see are at least respected. You will find it is expensive to get a great lawyer, but your future...
If the terms and conditions of your probation specify "monthly UA," then usually you would only be tested once per month. I would not count on this though. I don't think it will go very far with the judge for you to refuse a UA and try to play the "I already peed this month" card.
Just stay clean and you can pee without sweating too.
You should get representation so you have a chance at not going to prison. A 3d DWI is punishable by up to 10 years in prison. The minimum is 2 years.
You could get probation, but with a felony conviction , you would have serious hardships for the rest of your life. You have to do time in the county even if you get probation.
Get a really good lawyer.
Perhaps it was dismissed, but if you didn't get it expunged, the felony arrest will still show up on certain background checks. It sounds like you aren't sure how the case was resolved.
If you were charged with a felony, and you beat it, you need to get the arrest expunged from your record. An employer simply seeing an arrest for a felony is likely to pass you over as an applicant.
You can find self help cures for runny nose and maybe recipes for gumbo on the internet. You are not going to get free legal advice on complex issues. Firstly, because it is foolish to reveal and commit to writing, confidential details about a sensitive case.
Get a lawyer you can trust and talk to them in private about the details of your situation.
Your complaint with you lawyer is far too common. Odds are, your lawyer did not charge you much, and never really planned to fight for you. A good lawyer who plans to fight for you is going to charge you thousands.
Ineffective counsel doesn't become an issue until representation is completed. If you are not comfortable with the level of representation you are getting, fire your lawyer and hire another one.
Don't wait until you're convicted and hope for an ineffective counsel appeal....
