📘 Study Tips & State Info
Idaho DMV examiners zero in on the hazard classes that matter here — especially Class 2 (gases), Class 3 (flammable liquids), and Class 9 (miscellaneous). They'll ask you to match a specific chemical to its class. Study the federal placard chart until you can do it without looking.
They also emphasize the segregation table. You might get a question about loading chlorine next to ammonia — that's a no-go. Practice using the table in the CDL manual. And don't skip the Emergency Response Guidebook section. Idaho examiners ask at least two questions about how to find the right guide page for a given chemical.
One more thing: Idaho includes a couple questions about winter driving with hazmat — chain requirements and reduced speed limits on icy roads. The manual covers it briefly, but it's on the test. Know when you're required to chain up on I-84 near Shoshone.
You take the Idaho Hazmat test at any DMV office that offers CDL testing. Major locations include Boise (Chinden Blvd), Meridian, Idaho Falls, Coeur d'Alene, and Twin Falls. You need an appointment — walk-ins rarely work for CDL tests. Call ahead or book online through the Idaho Transportation Department website.
The test fee is $15 per endorsement written test. You also need to pass a TSA background check before you can get the Hazmat endorsement on your license. That's a separate application through the TSA website and costs $86.50. Start that process early — it can take weeks. Bring your medical certificate and proof of Idaho residency when you test.
Idaho doesn't have a separate state hazmat test beyond the federal one, but they do include a few state-specific questions about local regulations. The official Idaho CDL manual has a section on hazardous materials — that's your study guide. Don't rely on generic national practice tests alone.
About the Idaho Hazmat Test
Idaho moves a lot of hazardous materials — from anhydrous ammonia for potato fields to fuel and chemicals on I-84 through the Snake River Canyon. If you're getting your Hazmat endorsement, you need to know more than just the 9 hazard classes. You need to understand how to secure a load for mountain grades and what to do if something goes wrong in a remote stretch of US-95.
The Idaho Hazmat test is 30 multiple-choice questions. You need 24 correct to pass — that's 80%. The Idaho DMV administers it at their CDL testing locations. You'll take it after you pass the General Knowledge test, and it's part of getting your commercial learner's permit with the Hazmat endorsement.
This test covers the federal hazmat rules from the FMCSA, but Idaho examiners tend to focus on practical stuff you'll deal with here: placarding for agricultural chemicals, the Emergency Response Guidebook, and the paperwork you need at Port of Entry inspections. They also ask a few questions specific to Idaho's winter driving rules for hazmat vehicles.
