Signs & Signals
Idaho traffic signs use shape and color so their meaning is clear before you read the words. Recognizing signs and signals quickly is the foundation of safe driving and a large part of the knowledge test.
Rules of the Road & Right of Way
Right-of-way rules decide who proceeds first so intersections stay orderly. In Idaho you yield, keep right, and make room for emergency vehicles.
Safe Driving & Sharing the Road
Most crashes come from following too closely or failing to see others. Managing space and staying alert protects you and everyone around you.
Speed & Conditions
Posted limits assume good conditions, and Idaho's basic speed rule expects you to slow down when the road or weather is poor. Choosing a safe speed is one of the most important decisions you make behind the wheel.
Alcohol, Drugs & Graduated Licensing
Impaired driving is a serious crime in Idaho, and new teen drivers earn full privileges in stages that start unusually early. Knowing these limits protects your license and everyone on the road.
