For a driver age 21 or older operating an ordinary noncommercial car, which alcohol concentration meets Montana’s per-se DUI threshold?
Correct answer: 0.08 percent.
The ordinary adult threshold is 0.08 percent. This is not a promise that driving below it is safe or that other evidence of impairment cannot matter.

Which alcohol concentration meets Montana’s under-21 per-se DUI threshold?
Correct answer: 0.02 percent.
The under-21 threshold is lower than the ordinary adult threshold. Young drivers must not treat the adult figure as permission to drink and drive.

An officer lawfully requests an alcohol test under Montana’s implied-consent rules. Can refusal itself have driver-license consequences?
Correct answer: Yes; refusal can lead to loss of driving privileges.
Refusal is not a way to preserve driving privileges automatically. Montana’s implied-consent statute provides for license suspension when a driver refuses the required testing.

You hear a new exhaust leak and notice exhaust odors in the car. What should you do?
Correct answer: Have the leak corrected before relying on the vehicle for ordinary travel.
A leaking exhaust can expose occupants to toxic gases and cause drowsiness or death. Ventilation is not a repair.

The brake pedal suddenly travels to the floor during a pre-trip check. What is the appropriate decision?
Correct answer: Have the brakes checked and repaired before normal driving.
The handbook identifies a pedal going to the floor as a reason for professional brake inspection. Working lamps do not prove the brakes are sound.

Your car has front airbags. May you wear only the shoulder part of a two-part belt?
Correct answer: No; use both the lap and shoulder portions properly.
Airbags are only part of the protection system. Using only one portion of a two-part belt greatly reduces protection.

Before driving, how should you position the head restraint?
Correct answer: Adjust it so it can support the back of your head.
The restraint is intended to reduce whiplash in a rear impact. It should be adjusted for the person actually occupying the seat.

Which Montana high-beam dimming distances apply to an oncoming vehicle and a vehicle you are following?
Correct answer: Within 1,000 feet oncoming and within 500 feet following.
The current statute uses different distances for meeting and following. Lower the beam before it dazzles the other driver.

Blowing dust reduces the distance at which vehicles can be seen to about 400 feet in daylight. What is required?
Correct answer: Turn on the headlights and adjust speed for the limited view.
The handbook requires headlights when weather or blowing dust reduces visibility below 500 feet. Headlights also help other drivers see your car.

A one-year-old is traveling in an ordinary passenger car with no exemption. What restraint orientation does current Montana law require?
Correct answer: A compliant rear-facing child safety restraint used according to its instructions.
Current law requires rear-facing restraint below age two. The older handbook’s under-six/60-pound summary must not replace the current age-stage rule.

A three-year-old has not outgrown an appropriate child seat. Which restraint choices does current Montana law allow for this age stage?
Correct answer: A compliant rear-facing or forward-facing child seat with an internal harness.
The age-two-to-four stage requires an internal harness. Use an appropriate seat according to the manufacturer’s instructions.

A seven-year-old still fits the applicable child-restraint limits. Which current Montana option is appropriate?
Correct answer: An applicable compliant forward-facing harness seat or booster secured with a lap-shoulder belt.
The current four-through-eight age stage is not the older under-six/60-pound rule. Use the applicable restraint and follow its instructions.

A child seat is the correct type, but its belt routing conflicts with the manufacturer’s instructions. Is choosing the right type enough?
Correct answer: No; the restraint must also be installed, adjusted and used according to its instructions.
Proper type and proper use are separate requirements. Incorrect installation can undermine protection.

What are Montana’s current minimum ordinary motor-vehicle liability policy limits?
Correct answer: $25,000 for one person’s injury/death, $50,000 for two or more persons, and $20,000 property damage per accident.
The current code specifies 25/50/20. The linked handbook’s $10,000 property figure is outdated.

What advance turn-signal distances does the Montana handbook give for town and rural driving?
Correct answer: 100 feet in town and 300 feet on rural roads.
Give other drivers advance notice and use the proper lane. Avoid a misleading signal at an intervening entrance; make the intended turn clear.

You are on a one-way street and want to turn left onto another one-way street. No sign or officer prohibits it. What does Montana permit at a red light?
Correct answer: A left turn after a complete stop and yielding, if it is safe.
The permission is limited to the described one-way-to-one-way movement. Stop and yield to pedestrians and conflicting traffic.

Under Montana’s ordinary statutory speed limits, which situation can qualify for the allowance of up to 10 mph extra to complete a safe pass?
Correct answer: Traveling on a two-lane road in a designated passing zone.
Both a two-lane road and a designated passing zone are required. The exception concerns the ordinary statutory limits and completing a safe pass; it is not permission to disregard special speed zones, pass unsafely or keep speeding afterward.

A school bus on your two-lane roadway has stopped to unload children with red lights flashing. You approach from the opposite direction. Where must you stop?
Correct answer: At least approximately 30 feet from the bus.
The current rule applies from either direction on the same roadway and prohibits proceeding past the bus while the red lights operate.

A school bus ahead activates amber flashing lights as it prepares to stop for children. What should you do?
Correct answer: Slow to a reasonable speed and prepare to stop when the stopped bus activates red lights.
Amber warns of a planned loading stop. Prepare early rather than making a last-second stop or pass.

A school bus stops with red lights on the other roadway of a highway with separate roadways. You remain on your own roadway. What does the statutory exception allow?
Correct answer: You need not make the school-bus stop solely for that bus on the different roadway.
The exception depends on separate roadways, not merely a painted lane division. Continue watching for hazards and obey other controls.
