IDAHO DMV TOPICS

Your Idaho DMV Test, Broken Down by Topic

Know exactly what to study before test day. Explore 6 essential Idaho DMV topics, with clear explanations, key rules, helpful tips, and targeted practice questions for each one.

Learn what matters. Practice with purpose. Walk into the DMV prepared.

Topic 01

Right-of-Way & Intersections

Exam Difficulty:Medium

Understanding who has the right-of-way is one of the most heavily tested areas on the Idaho DMV exam. Most failures occur here.

Must-Know ID Tip: Mountain Road Yield Rule

When two vehicles meet on a steep single-lane mountain road where they cannot pass, the vehicle facing downhill must yield by backing up until the vehicle going uphill can pass safely.

Core Rules & Tested Concepts

At intersections without signs, yield to the vehicle on your right if it arrives at the same time.
At T-intersections, vehicles on the terminating road must yield to vehicles on the through road.
When making a left turn, you must yield to oncoming vehicles close enough to be a hazard.

Test your knowledge with specialized questions.Practice Right-of-Way rules

Topic 02

Speed Limits, Fines & Limits

Exam Difficulty:Hard

Idaho has strict default speed limits and penalty structures that you must memorize. Memorizing the exact numbers is key.

Must-Know ID Tip: School, Residential & Business Zones

Unless posted otherwise, the speed limit is 25 mph in school zones, business districts, and residential areas. The limit is 15 mph in blind intersections, alleys, and near railroad crossings.

Core Rules & Tested Concepts

Speed limits are halved or specifically restricted in active school zones when children are present.
Fines for speeding and other moving violations are doubled in active highway construction zones.
Passing speed limit near streetcars, trolleys, or buses when safe is no more than 10 mph.

Test your knowledge with specialized questions.Practice Fines & Speed Limits

Topic 03

Road Signs & Lane Markings

Exam Difficulty:Easy

Idaho uses standard signs with state-specific variations. Focus on regulatory sign shapes and double solid yellow line rules.

Must-Know ID Tip: Double Solid Yellow Lines

A double solid yellow line means no passing. You may cross them only to make a left turn into a driveway, a private road, or to make an authorized U-turn.

Core Rules & Tested Concepts

A diamond-shaped sign indicates a warning, notifying you of upcoming road conditions.
A red and white triangular sign pointing down always means Yield to oncoming traffic.
Two sets of double solid yellow lines spaced 2 feet or more apart are considered a barrier—do not drive over them.

Test your knowledge with specialized questions.View Road Warning Signs Guide

Topic 04

DUI Laws & Distracted Driving

Exam Difficulty:Hard

Covers blood alcohol limits, chemical test refusal rules, under-18 device usage, and general driving impairment laws.

Must-Know ID Tip: Zero Tolerance for Under-18 Devices

Drivers under 18 cannot use any phone or wireless device while driving—even if it is equipped with a hands-free setup. Handheld devices are illegal for all drivers.

Core Rules & Tested Concepts

The legal BAC limit is 0.08% for drivers 21+, but is 0.01% if you are under 21 or on DUI probation.
Under the "Implied Consent" law, driving in ID means you agree to chemical testing; refusal results in suspension.
A first DUI conviction can result in up to 6 months in jail, a license suspension, and severe fines.

Test your knowledge with specialized questions.Practice Distracted Driving rules

Topic 05

Parking, Curb Colors & Emergencies

Exam Difficulty:Medium

Frequently tested and heavily missed rules. Focus on hill parking wheel placement and different colored curb rules.

Must-Know ID Tip: Uphill vs. Downhill Parking Wheels

When parking downhill, turn your wheels toward the curb. When parking uphill with a curb, turn wheels away (left) from the curb. If uphill without a curb, turn wheels right.

Core Rules & Tested Concepts

Curb Colors: Red means no stopping; Green means limited-time parking; White means passenger loading only.
Yellow curbs are for commercial loading/unloading; Blue curbs are reserved exclusively for disabled parkers.
In an emergency, if your vehicle stalls on a railroad track, run at a 45-degree angle toward the oncoming train.

Test your knowledge with specialized questions.Practice Parking rules

Topic 06

Sharing the Road & Safety

Exam Difficulty:Easy

Sharing lanes safely with pedestrians, emergency vehicles, large semi-trucks, and bicyclists.

Must-Know ID Tip: Three-Foot Bicyclist Passing Law

Under Idaho's Three-Foot Safety Act, you must allow at least 3 feet of space when passing a bicyclist in the same direction. If 3 feet is not possible, slow down and wait.

Core Rules & Tested Concepts

You must stop for a school bus with flashing red lights and an extended stop arm, unless it is on a divided highway.
Yield to emergency vehicles with sirens or lights by pulling to the right edge of the road and stopping.
Do not linger in a large truck's blind spots—known as the "No-Zone" (front, sides, and directly behind).

Frequently Asked Questions

Your Questions Answered

Quick answers to the most common questions about the Idaho DMV test

How many questions are on the Idaho DMV permit test, and what is the passing score?

The Idaho Division of Motor Vehicles (DMV) knowledge test consists of 40 multiple-choice questions based directly on the official Idaho Driver’s Manual. You must answer at least 34 questions correctly to achieve an 85% passing score—one of the strictest passing thresholds in the nation. You can miss up to 6 questions; missing 7 results in a fail. The test is administered on computer touchscreens at county driver license offices.

What is the minimum age to get an Idaho Supervised Instruction Permit (SIP)?

In Idaho, you can apply for a Supervised Instruction Permit (SIP) at just 14½ years old (under I.C. § 49-303). Applicants under 18 must be enrolled in or have completed a state-approved Driver Education program, bring a parent/guardian to sign liability consent, provide proof of school enrollment, and pass a vision screening.

Who is legally qualified to supervise a permit driver in Idaho?

Under Idaho Code § 49-307, once driver education is completed, a permit driver under 17 must be accompanied by a licensed driver who is at least 21 years old seated in the front passenger seat next to the driver at all times. No other passengers are permitted in the front seat.

How long must you hold an Idaho SIP before taking the road skills test?

Idaho requires teen permit holders to hold their SIP for a minimum of 6 months (180 days) from the date driver education is completed. Warning: Any moving traffic violation conviction or curfew breach cancels the permit and completely resets the 6-month holding clock from day one.

How many supervised driving hours are required for Idaho teens?

Idaho law mandates that teen drivers log at least 50 hours of supervised driving practice, with at least 10 hours completed after dark (night driving), certified by a parent or legal guardian on the official Idaho Supervised Driving Log before scheduling the road skills exam.

What passenger and nighttime restrictions apply to Idaho drivers under 17?

Under Idaho Code § 49-307A, licensed drivers under age 17 face strict Graduated Driver Licensing rules:

Passenger Restriction: For the first 6 months of licensing, the teen may transport only ONE passenger who is not related to them by blood, marriage, or adoption.
Daylight Only for Under 16: Drivers under age 16 may only drive during daylight hours unless accompanied by a licensed adult age 21+.

What is the famous "Idaho Stop" law for bicycles?

Under Idaho Code § 49-720 (the original "Idaho Stop" law), bicyclists approaching a STOP sign may treat it as a YIELD sign (slowing down and yielding to cross traffic, but proceeding without stopping if clear). Bicyclists approaching a steady RED traffic light may treat it as a STOP sign (coming to a complete stop, yielding to oncoming traffic and pedestrians, then proceeding straight or turning right).

What are the default statutory speed limits in Idaho when unposted?

Unless posted otherwise, statutory speed limits under Idaho Code § 49-654 are:

School Zones: 20 mph.
Residential, Business & Urban Districts: 35 mph (Idaho’s default is 35 mph unless lower posted).
Rural State Highways: 65 to 70 mph.
Rural Interstate Freeways: 75 to 80 mph (maximum 80 mph for cars, 70 mph for heavy commercial trucks).

What are the legal parking distance rules in Idaho?

Under Idaho Code § 49-659, the Idaho Driver’s Manual specifies the following parking clearances:

Within 15 feet of a fire hydrant.
Within 20 feet of a crosswalk at an intersection.
Within 30 feet of a stop sign, yield sign, or traffic control signal.
Within 50 feet of the nearest rail of a railroad crossing.
Within 20 feet of a fire station driveway entrance (or 75 feet across the street).
When parallel parked, wheels must be within 18 inches of the roadside curb.

What are Idaho’s Zero Tolerance underage DUI laws and retake waiting periods?

Under Idaho Code § 18-8004, the legal Blood Alcohol Content (BAC) limits are: 0.08% for drivers 21+, 0.04% for commercial CDL drivers, and 0.02% (Zero Tolerance) for drivers under 21. Refusing a chemical test under Implied Consent carries an automatic 1-year absolute license suspension. If you fail the Idaho knowledge exam, you must wait 3 full business days before retaking.
