You are correct to use the word aggressive. Wake County is very aggressive in making DWI arrests and prosecuting those arrested. According to the facts you have provided, you are guilty of DWI. You are unlikely to stop the subpoena or otherwise keep the hospital record out of evidence. What is odd is that you were not forced to give a blood sample. You need to be concerned with your sentencing level and avoiding jail time.
22 over is not so simple. You are unlikely to just walk into court and achieve a desirable outcome. You may need to attend traffic school to get where you want to be on that charge. Hire yourself a good traffic lawyer. You can spend the money now and handle the matter properly or you can pay higher insurance premiums for the next three years. Good luck to you.
There is case law that states if the only evidence is the officer's observations, then the DWI charge must be dismissed. However, in your case there is additional evidence. First, you were in a car accident. Second, you admitted to the officer that you had been drinking earlier in the evening. So, it is highly unlikely your case would be dismissed. However, I take it from the facts you have stated that you did not perform roadside field sobriety tests, submit to a breath alcohol test, or...
I agree with the previous answers and would add that both Clonazepam and Diazepam are Schedule IV controlled substances. Possession without a prescription is a Class I felony. To argue that you were illegally in possession of a particular controlled substance as a defense to being illegally in possession of a different controlled substance is unlikely to get you very far.
I would have to say it is not legal as you would be aiding and abetting a direction probation violation. Your disclaimer is irrelevant as you appear to be quite aware of the intended use of your urine.
In North Carolina, DWI is an implied consent offense. What you received is a civil revocation under N.C.G.S. Sec. 16.5. Under that statute your license is automatically revoked for 30 days if you were found to have a BAC above the .08 legal limit or you refused the breathalyzer test. You may qualify for a limited driving privilege after 10 days. You may or may not be interested in the LDP. In any event, you can pick up your license after 30 days from the date of revocation.
You are not going to get far calling the arresting officer "crazy" or "stupid." If you were not in possession of an illegal substance, you will have the opportunity to go to court and plead not guilty. The State will then have to prove that you were in possession of an illegal substance. Samples will be tested. If no illegal substance is found in the samples, the DA should dismiss your case. However, if the samples prove to contain an illegal substance, you can expect to be prosecuted....
If you plead guilty to the charge, you will have a couple of points on your license, but your insurance rates should not increase. However, you may be able to get the charge reduced to improper equipment. It just depends on how things work in that county.
It is impossible to give you an answer without additional information. Your best bet is to consult with a defense attorney in your area. Depending on how you performed on the FST's, if you truly blew a .01 on the PBT, you may have a probable cause issue for the arrest. Many defense attorneys give free consultations.
