Yes, it is possible to be convicted of a DUI (driving under the influence) without a breathalyzer. There are several other ways that a driver can be deemed under the influence without a breathalyzer, such as having a blood alcohol concentration (BAC) above the legal limit, exhibiting impaired driving abilities, or failing field sobriety tests. In some cases, the prosecution may also rely on witness testimony, video evidence, or chemical tests (such as a blood test) to prove intoxication. However, the breathalyzer is a common and often crucial piece of evidence in DUI cases.
