When can a law enforcement officer require someone to submit to a PBT?

• A. Only during daytime
• B. If the officer has reasonable grounds to believe the person has alcohol in their body
• C. Only when there is a vehicle collision
• D. The driver consents to a PBT

Answer: (B)

At the roadside, the authority to require a preliminary breath test hinges on having reasonable grounds to believe the driver has alcohol in their body. That means there must be observable signs or evidence suggesting impairment, not just a random hunch. The test is used as a quick way to assess whether further action is warranted. It isn’t limited to daytime, nor is it required only if there’s a vehicle crash, and it isn’t simply about whether the driver consents. When reasonable grounds exist, a PBT can be requested to help determine next steps.
