Are DWI/DUI breath and blood tests always accurate?

NO! I could write pages upon pages of all of the problems with breath and blood testing. Problems with breath and blood tests, when successfully argued, are thrown out of evidence all of the time. These can be due to both human and machine error.

To keep it simple, you need to hire an attorney who dedicates their practice to DWI; your attorney should have the proper education and training on how to find these issues in your case and successfully argue them to the prosecutor, judge, or jury.
