Montana Permit Test Study Guide (2026)

Cover every topic on the Montana DMV permit test, ranked by how often they show up on the real exam.

The Montana Driver Manual is your main study tool. The MVD writes every test question from this book. Read each chapter. The manual covers Montana traffic laws, road signs, and safe driving practices. An adapted illustrated version is also available for learners who prefer images.

Montana Speed Limits

Speed limits are one of the most-tested topics on the MT permit exam, and the questions usually test Montana's statutory default limits -- what the speed is when no sign is posted. Under Mont. Code 61-8-303, Montana's default in an urban district is 25 mph. School zones can be lowered to as low as 15 mph by local authorities. On the interstate, the default is 80 mph outside a 50,000-population urban area (65 mph inside one); other public highways default to 70 mph in daytime and 65 mph at night. Always obey the basic-speed law: never drive faster than is safe for current conditions.

Alcohol & BAC Limits

Expect at least one alcohol question on the Montana permit test. Memorize the three BAC thresholds: 0.08% is the legal limit for drivers age 21 and older, 0.04% is the limit for anyone driving with a commercial driver license (CDL), and Montana's zero-tolerance threshold for drivers under 21 is 0.02% (Mont. Code 61-8-410) -- this is an absolute-liability offense, meaning no proof of impairment is needed. A BAC of 0.08% or higher brings full adult DUI charges instead.

Right-of-Way Rules

Right-of-way is the single most-missed topic across every state's permit test. The rules are simple once you memorize them. At a 4-way stop, the first vehicle to fully stop goes first; if two arrive together, the driver on the right has the right of way. At an uncontrolled intersection, yield to any vehicle already in the intersection and to the driver on your right. At roundabouts, yield to traffic already circulating and enter only when there is a safe gap. Always yield to pedestrians in any crosswalk, marked or unmarked, and to emergency vehicles with lights and sirens — pull right and stop. When turning left across oncoming traffic, you must yield to oncoming vehicles. Yield does not give you the right of way; it requires you to give it up.

Following Distance & Safety

Montana's basic rule (like its speed law) doesn't name a fixed following distance, only requiring a distance that's reasonable and prudent for conditions. The commonly-taught technique still applies: pick a fixed point on the road, wait for the vehicle ahead of you to pass it, then count one-thousand-one, one-thousand-two, one-thousand-three; if you reach the point before finishing the count, you're following too closely. Increase your distance further in poor conditions.

Road Sign Colors & Shapes

Road signs on the MT permit test follow the federal Manual on Uniform Traffic Control Devices, so shapes and colors are consistent across the country. Memorize the shapes first: octagon always means stop, downward triangle means yield, diamond means warning, pentagon marks a school zone, round warns of a railroad crossing, and horizontal rectangle is a guide sign. Then learn the colors: red is stop or prohibition, yellow is general warning, orange is construction, green is directions and exits, blue is driver services, brown is recreation, and fluorescent yellow-green is for schools and pedestrians. Practice identifying signs by shape and color alone — see the full visual cheat sheet on our Montana road-signs page.

Key Montana Numbers to Memorize

If you only remember a handful of facts going into the test, make it these. Every one of them maps to questions that have appeared on the real MT exam.

Parking Rules

Parking questions on the Montana permit test cover two patterns everywhere. For parallel parking, your wheels should be no more than 12 inches from the curb. For hill parking, the kerb rule decides which way your front wheels point: facing downhill (with or without a curb), turn the wheels toward the curb; facing uphill with a curb, turn the wheels away from the curb so they rest against it; facing uphill with no curb, turn the wheels toward the edge of the road. Always set the parking brake and leave the car in park (or in low gear with a manual).

Montana's no-parking zones (Mont. Code 61-8-354) you must memorize: within 15 feet of a fire hydrant, within 20 feet of a crosswalk at an intersection (never on the crosswalk itself), within 30 feet on the approach to a flashing beacon, stop sign, or official traffic control device, and within 50 feet of the nearest rail at a railroad crossing.

GDL Restrictions (MT)

Montana's learner's permit: log 50 hours of supervised driving, including 10 at night. The restricted license's night curfew runs 11 p.m. to 5 a.m. (exceptions for school, church, work, or farm-related activities). Passenger restrictions: no more than one unrelated passenger under 18 for the first 6 months (unless a licensed driver 18 or older supervises), then up to three for the second 6 months. Expect 1-3 GDL questions on the MT exam.

DUI & Drug Laws

DUI questions go beyond the BAC limits in Section 2. Three concepts you must know: implied consent means refusing a chemical test triggers automatic license suspension on top of any DUI charge. Prescription and over-the-counter drugs can also impair driving — antihistamines, sleep aids, painkillers, and some cold medicines list "do not operate heavy machinery" warnings, and driving impaired by them is a DUI even if you have a valid prescription. Marijuana — even where state-legal — is treated like alcohol for driving: any detectable impairment can result in a DUI, and edibles can take 1–3 hours to peak. The only safe BAC and the only safe THC level for driving is zero. There is no quick way to sober up; only time will lower your BAC.
