Can I beat a RI DUI charge if I failed a breath test?

Posted by Matthew Marin | Jul 17, 2017 | 0 Comments

We are frequently asked by potential clients if it is possible to beat a Rhode Island DUI charge if you have submitted to and failed a breath test. Like most questions in the law, the answer is not always a straightforward yes or no. On the positive side, it is absolutely possible to beat a RI DUI case after failing a chemical breath test. It is by no means automatic that you will lose your case and be convicted just because you took a chemical breath test and your readings were over the legal limit. On the other hand, it is also not a sure thing that your case can or will be beaten. 

A failed breath test strengthens the Prosecution's criminal DUI charge as it provides, if admissible, solid and concrete evidence regarding the motorist's blood alcohol content at the time they were operating the vehicle. This is called “per se” evidence of drunk driving. This concrete evidence of impaired operation is the prosecutor's easiest way to prove a DUI case.

That being said, before the Prosecutor can introduce this breath test evidence of the motorist's blood alcohol content to the Judge or the jury he must satisfy the statutory requirements. The DUI law in Rhode Island requires the prosecutor show that the Police complied with nearly a dozen procedural requirements before the evidence of the failed breath test can be given to the Judge or jury. A failure to comply with any one of these requirements can lead to the exclusion of the evidence from trial. Some of the statutory requirements for failed breath tests include: 

  • The Police had a lawful basis for stopping or coming into contact with the motorist;
  • The Police informed the motorist of the proper rights when he was arrested;
  • The Police informed the motorist of the proper rights prior to the breath test;
  • The Police continually observed the motorist for the 15 minutes prior to the administration of the breath test;
  • The Police used a new mouthpiece for each phase of the breath test;
  • The motorist's consent wasn't influenced by improper remarks by the Police;
  • The breath test results are within the Department of Health regulated margin of error;
  • A copy of the breath test results were mailed to the motorist within 72 hours of taking the test;
  • The breath test machine was certified by the Department of Health within the prior 30 days;
  • The breath test operator was certified by the Department of Health within the prior 365 days;

 If the Police investigation fails to establish that the entire list of statutory protocols was followed to the letter, the motorist can move and will likely be successful in excluding the breath test results from introduction to the Judge or jury at trial. The exclusion of such breath test results is extremely damaging to the Prosecutions case and will significant hinder their ability to obtain a conviction for drunk driving in Rhode Island.

 If a motorist is able to successfully exclude a failed breath test from evidence at trial, the Prosecution must rely solely on the observations of the arresting officer to prove the case. A skilled DUI trial attorney will have ample ammunition to attack the officer's observations and can typically draw some doubt as to whether the motorist was impaired at the time of operation. In the context of a criminal trial, the Prosecution must prove their case to the Judge or jury beyond a reasonable doubt. This high burden can be difficult to meet relying solely on the Police Officer's observations and the motorist's performance on the field sobriety tests.
