32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Octagon sign
- An eight-sided red sign means STOP. Come to a complete stop at the stop line, crosswalk, or edge of the roadway, yield to traffic and pedestrians, then proceed when clear.
- Yield sign
- An inverted triangle sign means slow down and give right-of-way to traffic on the intersecting road. Stop only if necessary to avoid a collision, then proceed when safe.
- Flashing red light
- Treat a flashing red signal exactly like a stop sign: make a full stop, yield to cross traffic and pedestrians, then proceed when the way is clear.
- Flashing yellow light
- A flashing yellow signal means slow down and proceed with caution. You do not need to stop, but you should be alert for cross traffic, pedestrians, or hazards.
- Solid yellow center line
- A solid yellow line on your side of the centerline means passing is prohibited in that direction. You may cross it only to turn left into a driveway or side road.
- Uncontrolled intersection rule
- At an intersection with no signs or signals, yield to any vehicle already in the intersection and to the vehicle on your right if you arrive at the same time.
- Four-way stop order
- At a four-way stop, the first vehicle to stop proceeds first. If two vehicles stop at the same time, the one on the left yields to the one on the right.
- Left turn right-of-way
- A driver turning left must yield to oncoming traffic going straight or turning right, and to pedestrians in the crosswalk. Wait for a safe gap before turning.
- Right turn on red
- After a complete stop, you may turn right on a steady red light unless a sign prohibits it. Yield to pedestrians and cross traffic before proceeding.
- Idaho urban speed limit
- Unless posted otherwise, the default speed limit in Idaho urban areas is 35 mph. Posted signs always take precedence over the default limit.
- Three-second rule
- Pick a fixed object ahead. You should reach it no sooner than three seconds after the vehicle in front. Add a second for each adverse condition such as rain or darkness.
- Move-over law
- On multi-lane roads, change lanes away from stopped emergency, tow, or maintenance vehicles with flashing lights. If you cannot change lanes, slow below the posted limit.
- Idaho rural speed limit
- Unless posted otherwise, the default speed limit on non-interstate rural highways in Idaho is 55 mph, and 65 mph on interstate highways.
- Cyclist passing clearance
- Idaho requires drivers to give bicyclists at least three feet of clearance when passing. If you cannot pass safely, wait behind until there is room.
- Truck No-Zone
- Large trucks have large blind spots on all four sides, especially the right side and directly behind the trailer. If you cannot see the driver's mirrors, the driver cannot see you.
- Truck right-turn off-tracking
- Large trucks swing wide and their rear wheels track inside the front wheels when turning right. Never squeeze between a turning truck and the curb.
- Crosswalk yielding rule
- Yield to pedestrians in marked and unmarked crosswalks. Do not pass a vehicle stopped at a crosswalk; it may be yielding to a pedestrian you cannot see.
- Idaho BAC limit
- Idaho's per se limit is 0.08% blood alcohol concentration for drivers 21 and older. Commercial drivers are limited to 0.04%, and drivers under 21 face zero tolerance.
- Implied consent law
- By driving in Idaho, you consent to chemical testing for alcohol or drugs. Refusing a test results in license suspension even without a DUI conviction.
- Idaho texting law
- Idaho law prohibits texting and manually entering data while driving. Hand-held phone use is also restricted in work zones and school zones.
- Idaho minimum insurance
- Idaho requires liability insurance of at least $25,000 per person and $50,000 per accident for bodily injury, plus $15,000 for property damage (25/50/15).
- Idaho child seat rule
- Children under 7 must ride in an approved child safety seat. Seat belts are required for all front-seat occupants and all passengers under 18 in any seat.
- Idaho instruction permit
- An Idaho instruction permit is available at 14½ with driver's education, or at 15 without it. Permit holders must complete supervised driving hours before a provisional license.
- Idaho point system
- Idaho assigns points for moving violations. Accumulating too many points within a set period can result in license suspension and higher insurance costs.
- Skid recovery
- If your vehicle begins to skid, ease off the accelerator and steer in the direction you want the front of the car to go. Do not slam the brakes.
- Bridge ice hazard
- Bridges and overpasses freeze first and thaw last because cold air circulates under them. Slow down and avoid sudden braking when crossing them in winter.
- Winter following distance
- On snow and ice, increase following distance to at least 8–10 seconds. Stopping distances can double or triple compared with dry pavement.
- Mountain downgrade braking
- On steep mountain downgrades, shift to a lower gear to control speed. Do not ride the brakes continuously, which can overheat them and cause failure.
- Roundabout right-of-way
- At a roundabout, yield to traffic already circulating from your left before entering. Do not stop once inside the roundabout; proceed to your exit.
- School bus stop arm
- When a school bus has flashing red lights and an extended stop arm, stop in both directions unless separated by a median. Remain stopped until the lights stop.
- Freeway merging rule
- When merging onto a freeway, adjust your speed to match traffic and yield to vehicles already on the freeway. Use the acceleration lane to build speed.
- Fog headlight rule
- Use low-beam headlights in fog, snow, and rain. High beams reflect off precipitation and reduce visibility. Idaho law requires headlights when visibility is limited.
