Key Topics in the Idaho Driver's Handbook 2026

Topic	Idaho Rule	85% Threshold Impact
Mountain Chain Law	ITD-activated requirement on US-20, US-30, I-84	Idaho-specific; can't skip this chapter
Farm Equipment Passing	Wait for wide load clearance on two-lane roads	Magic Valley & Treasure Valley daily reality
DUI Laws	BAC 0.08%; 90-day license suspension first offense	Suspension duration is tested specifically
GDL Supervised Hours	50 hours required (10 at night) before upgrade	Exact hours appear on exam

• Boise I-84 Merge Zones - ramp metering and lane drops at Meridian exits are tested situational awareness scenarios
_x0001_ & Signals - Including avalanche warning signs on ID-21 through the Sawtooth Mountains, open range livestock signs on US-93, and chain control signs
• Speed Limits - Idaho posts 80 mph on portions of I-84 and I-86; conditions-based reductions on mountain passes
• Right-of-Way - Four-way stops, roundabouts in Boise and Meridian, and uncontrolled rural intersections throughout southern Idaho
• Distracted Driving - Idaho's hands-free law and enhanced restrictions for permit holders
• Railroad Crossings - Stopping distances, active vs. passive crossing protocol - relevant across Idaho's extensive agricultural freight rail network

Idaho's road network has three distinct environments:

<

• Treasure Valley corridor (I-84, Nampa to Twin Falls) - urban interchange driving
• Central Idaho mountain passes - chain laws and grade speed reductions
• Snake River Valley plains - farm equipment on two-lane roads, daily reality

All three appear in the knowledge exam. All three appear on the written exam.

85% Is Not Flexible: Idaho's pass threshold is fixed. Miss 5 questions on a 40-question exam and you retake the full test. Drivers who assume one or two farm equipment or chain law questions are low-risk often discover otherwise.

Why the Idaho Manual Is the Only Source That Covers 85% of the Content You Need

• 40 questions, every one from this manual. Idaho ITD builds the knowledge test exclusively from the official Driver's Manual.
• Mountain chain laws are Idaho-specific. ITD-activated traction requirements on specific passes and interstates don't appear in any neighboring state's exam content.
• Farm equipment content is genuinely tested. Safe passing distances and protocol for slow-moving agricultural equipment on Magic Valley two-lane roads appear in the exam because they're daily reality for most Idaho drivers.
• 85% threshold leaves no room to skip chapters. Every section of the manual is potential exam content - none of it is safely ignorable.

From the Treasure Valley's I-84 corridor to the Sawtooth Mountain passes above Ketchum, the Idaho driver's handbook 2026 covers what Idaho roads and the ITD's 85% threshold require. Read every chapter - the margin for error is narrow.
