Which equipment is often used to measure blood alcohol content in drivers?

The Breathalyzer is a widely recognized device used to measure blood alcohol content (BAC) in drivers. This instrument operates by analyzing the breath exhaled by an individual to determine the level of alcohol present. It provides a quick and non-invasive method for law enforcement to assess whether a driver is operating a vehicle under the influence of alcohol. The accuracy and efficiency of the Breathalyzer make it a preferred choice in roadside assessments and legal scenarios.

Other equipment such as field sobriety tests or blood test kits may also be utilized in measuring impairment, but they serve different purposes. Field sobriety tests assess physical and cognitive abilities to determine impairment rather than measuring exact BAC levels. Blood test kits do provide an accurate BAC measurement but are more invasive and typically used in controlled settings or post-arrest situations. The Alco-sensor is a type of breath alcohol tester but is not as commonly referenced as the Breathalyzer in popular usage.
