PART I: THE PREVIEW
Mastering the 2025/2026 Idaho Transportation Department (ITD) regulations translates directly
to elite roadway command and the absolute mitigation of civil and administrative liability. This
document forges rote memorization into real-time operational mastery, ensuring you execute
flawlessly within Idaho’s distinct legal and topographical architecture.
The Critical Axioms
● The 15-MPH Passing Exemption: On two-lane highways posted at 55 mph or higher,
passenger vehicles may exceed the posted speed limit by up to 15 mph exclusively to
pass a vehicle traveling below the posted limit.
● The Idaho Stop (Bicycle Law): Cyclists may legally treat stop signs as yield signs, and
steady red lights as stop signs (proceeding only after a full stop and yielding). This does
not absolve them of yielding right-of-way to established traffic.
● The Universal "Move Over" Mandate: Drivers must slow down or move over for any
, stationary vehicle displaying flashing hazard lights, extending beyond just police and tow
trucks to include civilians and highway workers.
● The HB 664 Commercial Parity (Effective July 2026): Heavy commercial trucks (5+
axles, >26,000 lbs) are no longer restricted to lower urban interstate speeds; they now
share the exact same posted speed limits as passenger cars.
● The Absolute Mountain Right-of-Way: On steep, narrow mountain grades where two
vehicles meet, the vehicle facing downhill must reverse; the vehicle moving uphill holds
the absolute right-of-way due to gravitational physics.

PART II: THE ELITE TEST BANK
Tier 1: Foundational Syntax & Application
Q1: You are operating a passenger car on a two-lane Idaho highway with a posted speed limit
of 65 mph. The vehicle ahead of you is traveling at 60 mph. Based on the principles of Idaho
passing statutes, which action/conclusion is the MOST ACCURATE? A) You may temporarily
accelerate to 80 mph to execute the pass, then immediately decelerate to 65 mph once the
maneuver is complete. B) You may legally pass, but your absolute maximum speed during the
maneuver cannot exceed 65 mph under any circumstances. C) You may temporarily accelerate
to 70 mph, as the passing speed exemption is strictly capped at 5 mph over the posted limit. D)
You may accelerate to 80 mph only if passing in a designated multi-lane commercial passing
zone.
● The Answer: A (You may temporarily accelerate to 80 mph to execute the pass, then
immediately decelerate to 65 mph once the maneuver is complete.)
● Distractor Analysis:
○ A is correct: Idaho law explicitly provides a 15-mph exemption for passenger
vehicles passing slower vehicles on two-lane highways posted at 55 mph or higher.
○ B is incorrect: This is a common novice misconception that ignores Idaho's unique
overtaking exemption designed to minimize time spent in opposing lanes.
○ C is incorrect: The statutory allowance is exactly 15 mph over the limit, rendering a
5-mph cap analytically false.
○ D is incorrect: The exemption applies specifically to the opposing lane used for
passing on two-lane roads; utilizing special multi-lane passing lanes requires
, adherence to the standard speed limit.
The Mentor's Analysis: Idaho prioritizes minimizing the time spent in the opposing lane of
traffic on high-speed, two-lane rural roads. When facing a slower vehicle on a two-lane highway,
the immediate priority is executing a rapid, safe overtake. By utilizing the 15-MPH Exemption,
you bypass the common trap of lingering in the danger zone. Professional/Academic
Intuition: Passing Exemption = +15 mph on 2-lane roads (55+ mph) to pass a slower
vehicle.
Q2: Under Idaho Code § 49-720, a bicyclist approaches an intersection controlled by a steady
red traffic light. There is no oncoming traffic. Based on the principles of the Idaho Stop Law,
which action/conclusion is the MOST ACCURATE? A) The cyclist must slow to a reasonable
speed and roll through the intersection, treating the red light as a yield sign. B) The cyclist must
come to a complete stop before entering the intersection, yield, and then may proceed with
caution. C) The cyclist must legally dismount the bicycle and walk it across the intersection to
utilize pedestrian right-of-way. D) The cyclist must remain completely stopped until the electronic
signal cycles to a steady green light.
● The Answer: B (The cyclist must come to a complete stop before entering the
intersection, yield, and then may proceed with caution.)
● Distractor Analysis:
○ A is incorrect: Treating a red light as a yield sign is a lethal misapplication of the
statute; that rule applies strictly to stop signs.
○ C is incorrect: Dismounting is not legally required under the Idaho Stop law, which
regulates the operation of human-powered vehicles.
○ D is incorrect: Waiting for a green light is technically safe but legally unnecessary
under Idaho's progressive bicycle statutes, rendering this an outdated methodology.
The Mentor's Analysis: The Idaho Stop distinguishes heavily between stop signs (yield) and
red lights (stop, then proceed). When facing a red light on a bicycle, the immediate priority is a
full cessation of momentum. By utilizing the Stop-Then-Proceed Protocol, you bypass the
common trap of running a red light illegally. Professional/Academic Intuition: Bicycle Red
Light = Stop Sign; Bicycle Stop Sign = Yield Sign.
Q3: You are driving on a five-lane road (two travel lanes in each direction with a center turn
lane). An oncoming school bus in the opposite lane halts and activates its flashing red lights and
stop arm. Based on the principles of Idaho traffic control statutes, which action/conclusion is the
MOST ACCURATE? A) You must come to a complete stop and wait for the bus to deactivate its
lights. B) You must move into the center turn lane and proceed cautiously past the bus. C) You
must proceed with extreme caution; stopping is not legally required for opposing traffic on this
road configuration. D) You must stop only if you are traveling in the inner-most lane closest to
the center turn lane.
● The Answer: C (You must proceed with extreme caution; stopping is not legally required
for opposing traffic on this road configuration.)
● Distractor Analysis:
○ A is incorrect: Stopping in both directions is only mandated on roads with three or
fewer lanes.
○ B is incorrect: Utilizing a center turn lane as a continuous bypass lane is illegal and
highly dangerous.
○ D is incorrect: Lane proximity does not dictate the rule; the total structural number
of lanes (four or more) dictates the exemption for opposing traffic.
The Mentor's Analysis: Traffic division dictates school bus protocols. When facing a school
bus on a road with four or more lanes, the immediate priority is maintaining traffic flow for
