How likely can a DUI charge can be dismissed if I refuse to take all test?

There is no way that anyone can say without first having seen the police report.

Very little since they do not NEED the tests to convict if the jury believes from the testimony that you were operating under the influence. Get a lawyer.

If a blood test was taken and it shows that you had a BAC over 0.08 then there is little chance of the charge being thrown out. If no tests were taken whatsoever, then you could still face charges for impaired driving.

Without knowing all of the facts of the arrest and the arresting officer's observations, it is difficult to answer this question. If charges were filed, the chances of it being dismissed are probably slim.

Whether or not your case can be dismissed will pivot mostly on the legal grounds for the initial contact by law enforcement. When you signed for driver's license you agreed to provide a sample of your blood or breath if arrested for suspicion of driving under the influence, you didn't comply with "implied consent." This means that if the Officer's lawfully contacted you and suspected you of DUI you had to provide a chemical test. An experienced DUI attorney can help you navigate the intricacies of both the criminal courts and the DMV (you are looking at a possible suspension of your license of 1, 2 or three years), possibly save your license and help you avoid a horrible situation. Direct answer, your odds are slim without a lawyer, better with a lawyer.

Probably.... slim to none. The officer observed your driving, which is a factor and the reason for your stop. There may also be other people who witnessed your driving. The fact that you refused all tests can be told to the judge or jury.. Also, regardless of whether you are found guilty of the DUI, the simple fact that you refused the breath test will result in a mandatory license revocation by DOL for a minimum of one year. You diod not do yourself any favors by refusing the breath test. Before you mess the case up any more, you may want to speak with an attorney.

What other evidence do they have? Without reading the police report and finding out what other evidence the prosecutor has available, no attorney can tell you. You need to hire an attorney or get a public defender then they can tell you.

When you say thrown out, I assume you are talking about a dismissal. The chances of that are remote. In Massachusetts, which is where I practice and the only location in which my answers pertain, the DA's office does not dismiss DUIs, period. Even if the case is a sure loss for the prosecution, they would prefer that a judge or jury make the determination of not guilty than risk the scrutiny of the media or the public for dismissing a charge with such political volatility. You may have seen the article in the Boston Globe a few months ago questioning why such a high percentage of DUIs that go jury waived (tried before a judge instead of a jury) result in a Not Guilty. One of the major reasons for this is because the DA's office will not dismiss a DUI, no matter how weak their position. Therefore, a seasoned lawyer will often take these cases to trial before a judge and not feel it necessary to take the additional time it takes to try it in front of a full jury. It certainly helps your position tremendously if there is no Field Sobriety Test (FST) evidence or Breath Test evidence. However, the DA will still put the arresting officer on the stand to testify as to his opinion of your condition at time of arrest. Do not take this lightly. The Commonwealth will do everything within their power to convict you, even without the FST and BT evidence. In fact, there are many judges in MA courts that will even convict you on marginal evidence in DUI cases. They too as concerned with public opinion and NO ONE wants to look weak or unconcerned with drinking and driving. Hire a good lawyer and let them do their job and you should be fine.

You have a better case than most, but it won't mean much if you don't have a DUI specialist representing you in court. You absolutely need a lawyer who knows this stuff, otherwise a refusal DUI has worse consequences than a regular DUI.

It all depends but I think your chances get better with a qualified drunk driving attorney in your area.
