Getting waved into a DUI checkpoint in Bozeman can be unsettling, even if you haven’t had a drink. Knowing your DUI checkpoint rights before you’re ever stopped can make the encounter go more smoothly, and matters even more if the stop leads to an arrest.
What You're Required to Do
You’re required to provide your license, registration, and proof of insurance when asked, and to comply with an officer’s lawful instructions during the stop. Montana’s implied consent law also means that driving on state roads is treated as agreement to a breath, blood, or urine test if an officer develops reasonable suspicion of DUI later in the encounter.
What You're Not Required to Do
You are not required to answer questions about where you’ve been, whether you’ve been drinking, or how much. You can be polite and still decline to answer those specific questions. You’re also not required to perform field sobriety tests, though refusing can factor into an officer’s decision on whether to pursue further testing.
If the Stop Leads to a DUI Charge
Montana defines a DUI as a BAC of 0.08% or higher, a BAC under 0.08% with signs of impairment, or driving under the influence of marijuana, prescription medication, or another impairing substance. If a checkpoint stop results in an arrest, a first offense carries a fine of $300–$1,000, up to 6 months in jail, and up to a 6-month license suspension.
The Breath Test Decision
Refusing a breath, blood, or urine test after a lawful arrest can trigger an automatic license suspension, typically 6 months or longer, loss of eligibility for a probationary license, and the refusal being used as evidence in court. You generally have 30 days from your arrest to request an administrative hearing challenging any suspension.
What to Do After a Checkpoint Arrest
- Say as little as possible beyond basic booking information
- Note details about the checkpoint itself while they’re fresh, location, time, and how the stop was conducted
- Contact a DUI defense lawyer as soon as possible given the 30-day hearing deadline
