What are the two types of authorized breath measuring devices?

The correct answer identifies the two types of breath measuring devices based on their usage and functionality: portable breath testing devices and non-portable breath testing devices.

Portable breath testing devices are designed for field use, allowing law enforcement personnel to conduct tests at various locations, which enhances their ability to enforce laws pertaining to impaired driving. These devices are typically lightweight, battery-operated, and easy to use, making them suitable for quick assessments in a range of environments.

On the other hand, non-portable breath testing devices are usually found in controlled environments like police stations or medical facilities. These devices tend to be more complex and may provide more accurate results due to their advanced technology. They might require a stable power source and often produce results that are admissible in court settings, meaning they are calibrated and maintained to meet specific standards.

Understanding these distinctions helps clarify the role each type of device plays in measuring blood alcohol content (BAC) and demonstrates the varied applications of breath measurement technology in law enforcement and public safety.
