What can trigger a Breathalyzer test?

A Breathalyzer test can be triggered by various factors, primarily when law enforcement suspects a driver may be under the influence of alcohol. Common triggers include erratic driving, involvement in a traffic accident, or violating traffic laws. Additionally, checkpoints for DUI enforcement may also prompt testing. In some cases, an officer may request a Breathalyzer if they notice signs of impairment, such as slurred speech or the smell of alcohol.
