You probably have heard of the Breathalyzer, but probably not the Brushalyser. Now you have. The Brushalyser is at the intersection of oral hygiene and traffic safety: it’s a toothbrush which doubles as a portable breath alcohol test. But should you rely on your toothbrush to determine whether it’s safe…
Ohio’s DUI laws (called ‘OVI’ in Ohio) criminalize driving with a prohibited breath alcohol concentration. To determine whether a person has a prohibited breath alcohol concentration, law enforcement officers use breath-testing machines. If a person refuses a breath test, there are consequences. However, differences in height, age, gender, and smoking…
A police officer discarded evidence that a DUI suspect blew under the ‘legal limit’. According to WCNC, the suspect was involved in a one-car accident and pulled her vehicle into a gas station parking lot. An officer went to the gas station and had the suspect perform field sobriety tests.…
OVI trials sometimes involve testimony from expert witnesses. Those witnesses include pharmacologists who testify about the accuracy of the defendant’s breath test result.

Clean hands is an obsession for some people. In addition to frequent hand-washing, many people also use alcohol-based hand sanitizers. Aside from the potential issues with dry skin and weakened immune system (not to mention OCD!), use of hand sanitizers can also affect the results of a breath alcohol test.…
When a machine is given the power to convict a person of a crime, we should be absolutely certain the machine is working properly. In Ohio, machines are used to measure the concentration of alcohol in the breath of drivers. A driver who operates a vehicle with a breath alcohol…
Joe was arrested for DUI / OVI, and the officer had Joe take a breath test and a urine test. The breath test showed an alcohol level under Ohio’s limit, and the urine test showed an alcohol level over Ohio’s limit. Based on the urine test result, Joe was prosecuted…
A smartphone app for breath-alcohol-testing was so promising that all five investors on Shark Tank collaborated on a deal for the first time. In 2013, Charles Yim went on the show and pitched his app to the Sharks. The Sharks collectively invested $1 million in Yim’s company Breathometer, Inc. for…
