Sample questions from this test, with answers
Want to test yourself first? Take the test above before reading these. Every answer below is checked against the source shown.
1. You are on an Idaho highway with two lanes in each direction. A school bus going the opposite way stops with red lights flashing. What must you do?
- A. Stop until its red lights turn off
- B. Stop, then pass at 15 mph or less
- C. Proceed with care; you need not stop (correct)
- D. Pull onto the shoulder and wait there
Why: Idaho does not require traffic going the opposite direction to stop for a school bus on a highway with four or more lanes, two in each direction. Traffic behind the bus must still stop.

2. Your right wheels drop off the pavement onto a clear shoulder. What does the Idaho manual say to do before returning to the road?
- A. Brake hard and stop right on the shoulder
- B. Steer back onto the pavement right away
- C. Speed up so the tires climb the edge
- D. Steer straight and slow down gently first (correct)
Why: Grip the wheel, steer straight and stay on the shoulder if it is clear. Take your foot off the gas and brake gently. Once you have slowed and see a gap in traffic, steer back on without oversteering.

3. A black-and-white rectangular sign reading 'NO TURN ON RED' means:
- A. Turn on red only if no cars are coming
- B. No turning on red, even after stopping (correct)
- C. Only left turns on red are banned here
- D. Turns are never allowed here
Why: A 'No Turn on Red' sign prohibits turning while the signal is red, even after a complete stop. You must wait for a green light to turn.
4. When may a driver enter or cross a bike lane?
- A. To pass slower cars when traffic is heavy
- B. Never, under any circumstances
- C. To turn or cross to parking, yielding to cyclists (correct)
- D. To wait in it while the car ahead of you turns
Why: Bike lanes are for bicyclists. You may enter or cross one only when needed to turn, enter or leave a driveway or alley, or park where allowed, and you must yield to bicyclists first. States differ on details: California lets you merge into the bike lane before a turn, while Connecticut and Hawaii only let you cross it.

5. What is the most effective way to stay alert on a long drive?
- A. Drink coffee or an energy drink each hour
- B. Keep the window open and the air cold
- C. Take breaks every 2 hours or 100 miles (correct)
- D. Turn up the radio and sing along
Why: The only real cure for drowsiness while driving is sleep. Take breaks at least every 2 hours or 100 miles. Coffee provides temporary relief but is not a substitute for rest.

6. A pentagon (5-sided) shaped sign is associated with:
- A. Hospital zones
- B. School zones (correct)
- C. Construction areas
- D. No-passing zones
Why: Pentagon-shaped signs (pointing up or down) are used for school zones and school crossings. They are yellow-green in color and alert drivers that children may be present.
