The PBT law permits a police officer to request a driver suspected of DWI to _____________.

A police officer's ability to request a driver suspected of driving while intoxicated (DWI) to submit to an on-the-spot breath test is grounded in the use of Portable Breath Test (PBT) devices. These tests allow officers to quickly assess whether a driver has a blood alcohol concentration (BAC) at or above the legal limit. The immediacy and convenience of a PBT enhance roadside evaluations, helping officers make informed decisions regarding arrests or further testing.

Unlike blood tests, which require lab analysis and a more invasive procedure, or field sobriety tests that assess physical coordination and cognitive functions, the PBT serves as a preliminary assessment tool that can be performed quickly and with minimal intrusion. The ability to request this type of breath test is specific to the context of a DWI suspicion, making it a practical and efficient way to gather evidence in the field. Thus, the correct option highlights the direct purpose of PBT laws in enhancing law enforcement's ability to address impaired driving effectively.
