Idaho DMV Practice Test 2026

1. Nothing is wrong; speeding up to merge in is perfectly fine
2. Entering vehicles must yield to circulating traffic, not force in
3. It is fine as long as no other car has a signal on
4. It is required whenever traffic is heavy that day

Correct answer: Entering vehicles must yield to circulating traffic, not force in. Vehicles entering a roundabout must yield to traffic already inside it; speeding up to force an entry can cause a collision.

1. No one; a green light always means you may go right away
2. Only pedestrians, never other vehicles
3. Only vehicles that are turning right at that moment
4. Vehicles, pedestrians, or cyclists still crossing

Correct answer: Vehicles, pedestrians, or cyclists still crossing. Even with a green light, you must yield to any vehicles, pedestrians, or cyclists still legally finishing their crossing of the intersection before you proceed.

1. The license is suspended for 30 days
2. The license is revoked permanently
3. A warning letter is sent
4. A mandatory course is required immediately

Correct answer: A warning letter is sent. Reaching 8 to 11 points within 12 months results in a warning letter from the department, not a suspension yet.

1. It has no effect if your tires are new
2. It reduces the tires' grip on the road, so braking takes longer
3. It only matters at speeds under 10 mph
4. It shortens braking distance by cooling the brakes

Correct answer: It reduces the tires' grip on the road, so braking takes longer. Less friction between tires and a wet or icy road means it takes longer for braking to slow the vehicle down.

1. The car on the left
2. The car on the right
3. Neither; both must wait for a third car to arrive
4. The car that signals first

Correct answer: The car on the right. When cars reach a stop sign at the same time from directions that cross each other, the driver on the right goes first and the driver on the left yields.

Source: New York Driver Handbook, PDF p.34, driver on the left yields to driver on the right

1. Loose enough to slide two fists underneath easily
2. Across the stomach, positioned as high as possible
3. Snug and low across the hips, not loose or tucked behind the back
4. It does not matter, as long as it is buckled

Correct answer: Snug and low across the hips, not loose or tucked behind the back. The lap belt should sit snug and low across the hips after fastening. If it is worn too loose, too high across the stomach, or tucked behind the body, it will not work correctly and the person could be seriously injured in a crash.

1. Stop immediately and wait for the brakes to dry on their own
2. Slow down and dry the brakes by applying light pressure while driving
3. Pump the accelerator hard to force the water out
4. Ignore it, since wet brakes work the same as dry ones

Correct answer: Slow down and dry the brakes by applying light pressure while driving. Brakes can get wet and lose some of their grip after driving through heavy rain or standing water. A driver should slow down and lightly apply the brakes while driving until they dry out and work normally again.

1. 7 seconds
2. 3 seconds
3. 2 seconds
4. 6 seconds

Correct answer: 3 seconds. Idaho's handbook recommends at least 3 seconds of gap under normal, favorable conditions.

1. 1000 feet
2. 600 feet
3. 500 feet
4. 100 feet

Correct answer: 500 feet. In Idaho, you must dim your high beams to low beams within 500 feet of an oncoming vehicle so you do not blind the other driver.

1. Ignore it completely since it's not in your lane
2. Stop your vehicle next to it to offer help
3. Move over a lane, or slow down if you cannot
4. Turn on your high beams to see better

Correct answer: Move over a lane, or slow down if you cannot. Move-over laws generally require drivers to move over a lane away from a stopped vehicle displaying warning lights, or to slow down if changing lanes is not possible.

1. Expect this reaction and give the motorcyclist extra room
2. Assume the rider is being careless and pass immediately
3. Honk to warn the rider they are drifting
4. Follow closely so the rider knows a car is behind them

Correct answer: Expect this reaction and give the motorcyclist extra room. Road conditions that barely affect a car, such as potholes, gravel, wet or slippery surfaces, and railroad tracks, can force a motorcyclist to change speed or direction suddenly. Drivers should recognize this and leave extra room instead of reacting with a horn or by following too closely.

1. Turn off the ignition immediately while still moving
2. Pump the accelerator repeatedly to free it
3. Shift into a higher gear to reduce engine strain
4. Shift into neutral and apply the brakes

Correct answer: Shift into neutral and apply the brakes. If the accelerator sticks, a driver should shift into neutral right away and apply the brakes, then look for a safe way off the road, warning other drivers with the horn and hazard lights. The ignition should only be turned off once the vehicle has stopped, since turning it off while moving can lock the steering.

1. You must never cross this type of line
2. It simply marks the edge of the roadway
3. It only indicates a pedestrian crossing area
4. You may cross it to change lanes or pass safely

Correct answer: You may cross it to change lanes or pass safely. A broken or dashed line permits you to cross it to pass another vehicle or change lanes, as long as it can be done safely.

Source: Texas Driver Handbook, PDF p.33, broken or dashed lines permit you to pass or change lanes, if safe

1. 200 feet
2. 1,000 feet
3. 500 feet
4. 50 feet

Correct answer: 500 feet. Idaho law requires headlamps to be dimmed 500 feet before meeting an oncoming vehicle.

1. No, it is reserved exclusively for a single direction
2. Yes, as long as each driver is careful and yields
3. No, only emergency vehicles are allowed to use it
4. Yes, but only during daylight hours

Correct answer: Yes, as long as each driver is careful and yields. Because the center left-turn lane is shared by traffic moving both ways, drivers from each direction must watch for one another and yield as needed.

1. Come to a complete stop, then proceed slowly
2. Treat it exactly the same as a solid red light
3. Slow down and go through with care; no stop required
4. It only applies to pedestrians, not vehicles

Correct answer: Slow down and go through with care; no stop required. A flashing yellow signal warns you to slow down and proceed carefully; unlike a flashing red, it does not require a complete stop.

Source: California Driver Handbook, PDF p.42, Flashing Yellow: proceed with caution, you do not need to stop

1. The train tracks at this particular location have been permanently removed
2. Only freight trains use this crossing
3. Trains on this track can travel faster than 80 mph, giving drivers less time to react
4. The crossing has no crossbuck sign posted

Correct answer: Trains on this track can travel faster than 80 mph, giving drivers less time to react. This sign warns that trains on that line can travel at very high speed, so a train may arrive much sooner than a driver expects.

1. Flash your own high beams repeatedly and stare directly at their headlights
2. Look toward the right edge of the road or lane markings, and slow down if needed
3. Close your eyes briefly
4. Speed up to pass the glare quickly

Correct answer: Look toward the right edge of the road or lane markings, and slow down if needed. Looking directly at oncoming high beams temporarily ruins your night vision. Instead, look toward the right edge of the roadway or the lane markings to keep your bearings, and slow down if you need more time to react.

1. 3:00 a.m.
2. 7:00 a.m.
3. 5:00 a.m.
4. 6:00 a.m.

Correct answer: 5:00 a.m.. The GDL nighttime restriction in Idaho ends at 5:00 a.m., after which normal provisional-license driving privileges resume.

1. Yes, they are exactly the same rule
2. No, they are separate restrictions that can both apply
3. No, the passenger limit replaces the daylight rule at age 16
4. Yes, but only for permit holders

Correct answer: No, they are separate restrictions that can both apply. Idaho's handbook lists the daylight-only rule and the under-17 passenger limit as two separate, additional restrictions.

Source: Idaho Driver Handbook, p.16, Restriction When Under 16; Restriction When Under 17

1. Only once, at the halfway point of the trip
2. About every 100 miles or every two hours
3. Every 500 miles, no matter how long the trip is
4. Breaks are unnecessary if the driver had a full night's sleep

Correct answer: About every 100 miles or every two hours. Scheduled stops every 100 miles or two hours - even before you feel tired - are a recurring recommendation for fighting highway hypnosis and fatigue.

Source: Texas Driver Handbook, Ch9 Fight Highway Hypnosis p.48 - 'Stop often. Even if you are feeling well, you should stop at least every two hours or every 100 miles.'

1. Stop completely and wait for a hand signal
2. Speed up in order to clear the area quickly
3. Slow down and proceed carefully as directed
4. Turn around and take another route instead

Correct answer: Slow down and proceed carefully as directed. A flagger holding the SLOW side of a paddle sign is telling drivers to reduce speed and proceed carefully through the work zone.

Source: Texas Driver Handbook, PDF p.35, flagger uses stop/slow paddles to direct traffic through work zones

1. Because red and white paint is simply cheaper to produce
2. Because those specific colors are required by law for headlights
3. There is no real reason; it is only a modern styling trend
4. So drivers can tell a binding rule apart from a warning

Correct answer: So drivers can tell a binding rule apart from a warning. The color scheme helps drivers instantly separate a rule they must obey from a warning that only alerts them to a hazard.

Source: Florida Driver Handbook, PDF p.54, Traffic Sign Colors

1. Come to a complete stop and wait for green
2. Slow down and proceed if the way is clear
3. Stop only if other vehicles happen to be present
4. Proceed carefully without stopping

Correct answer: Come to a complete stop and wait for green. A steady red light always means stop completely; you may not proceed until the light turns green, other than a legal stop-then-turn on red where allowed.

1. .08 percent
2. .04 percent
3. .02 percent
4. .01 percent

Correct answer: .04 percent. Idaho sets the commercial vehicle blood alcohol threshold at .04 percent.
