Question 1 of 30
1. Your GPS routes you through a Colorado neighborhood of homes and parked cars with no posted speed limit. State law caps your speed there at what value?
Show answer & explanation
Correct answer: D. State law gives unposted residential areas in Colorado a default cap of 30 mph. Parked cars shrink your view of crossing pedestrians, which is exactly why the cap is low. Posted signs, where present, replace the default.
2. You are in the right lane when you see a yellow diamond sign showing the right lane narrowing into the left lane. What should you do?
Show answer & explanation
Correct answer: B. A lane-ends sign warns your lane will disappear, so signal, match the other lane's speed, and merge before the pavement runs out. Drivers in the ending lane must yield to through traffic. Early, smooth merges prevent the last-second squeeze.
3. How close to a fire hydrant may you park in Colorado?
Show answer & explanation
Correct answer: A. Colorado lists no parking within 15 feet of a fire hydrant. Other banned spots include intersections, tunnels, and ramps. Do not reuse a railroad or signal distance for the hydrant.
4. After two drinks at a barbecue in Colorado, you consider driving home. For a driver 21 or older, that becomes illegal starting at which BAC?
Show answer & explanation
Correct answer: A. Driving in Colorado becomes a per-se DUI at a BAC of 0.08%. Drinks affect people differently, so you cannot reliably guess your number. When you have been drinking, the smart decision is simply to skip driving.
5. In Colorado, supervised behind-the-wheel practice with a permit can begin once a teen reaches which age?
Show answer & explanation
Correct answer: C. Supervised practice starts at 15 in Colorado, once the teen holds a learner's permit. Every practice hour with a licensed adult builds judgment that classroom study alone cannot teach, which is why the permit stage exists.
6. An orange sign with a black arrow reads DETOUR. What is this sign telling you?
Show answer & explanation
Correct answer: A. Detour signs guide you along a temporary route when the normal road is closed, often for construction or an emergency. Keep following the arrows until the detour ends, and the route will return you to your original road.
7. A yellow diamond-shaped sign ahead shows a black walking figure. As you approach the marked crossing, what is the required response?
Show answer & explanation
Correct answer: B. A pedestrian crossing warning sign means people may be entering the roadway ahead, so reduce speed and prepare to stop. Pedestrians lose in a collision with a car. Treat the walking figure as a person already stepping off the curb.
8. Do automated driver-assistance features remove your duty to watch the road, according to NHTSA?
Show answer & explanation
Correct answer: A. Official NHTSA automated-vehicle guidance says Every vehicle currently for sale in the United States requires the full attention of the driver at all times for safe operation. Even the highest level of driving automation available to consumers requires the full engagement and undivided attention of drivers.
9. You come to an intersection where the signal is flashing red. How should you treat it?
Show answer & explanation
Correct answer: D. A flashing red light works exactly like a stop sign: stop fully, yield to traffic and pedestrians, then proceed when the way is clear. Flashing red still means red, so a complete stop is required.
10. Can prescription or over-the-counter medicine make driving illegal, according to NHTSA?
Show answer & explanation
Correct answer: A. Official NHTSA drug-impaired-driving guidance says it’s illegal everywhere in America to drive under the influence of alcohol, marijuana, opioids, methamphetamines, or any potentially impairing drug–prescribed or over the counter.
11. You are low on fuel on a long highway drive. Signs of which color point you to services such as gas, food, lodging, and hospitals?
Show answer & explanation
Correct answer: B. Blue signs mark motorist services, including fuel, food, lodging, rest areas, and hospitals. They let travelers plan a stop before leaving the highway. When your body or your car needs something, look for blue.
12. A classmate in Colorado claims the adult DUI line is 0.10%. The official per-se BAC for drivers 21 and older is which value?
Show answer & explanation
Correct answer: C. Your classmate is using an outdated number. Colorado treats 0.08% as the adult per-se line. Memorize the current figure from the official handbook, not a rumor from an older relative.
13. Besides nighttime, when should you turn on your headlights?
Show answer & explanation
Correct answer: D. Turn on your headlights whenever conditions cut visibility, including rain, fog, snow, dusk, or dawn, because lights help other drivers spot you as much as they help you see. Handy habit: wipers on or gray sky means lights on.
14. You are on a through street. A driver on a driveway to your right is waiting to enter. Who must yield?
Show answer & explanation
Correct answer: B. Drivers leaving a driveway, alley, or parking lot yield to all traffic on the street, including bikes and people walking. The street already has the flow. Think: entering traffic waits; through traffic keeps moving unless a sign says otherwise.
15. You are studying for the Colorado permit knowledge exam and want to schedule it as early as the law allows. You can hold a learner's permit beginning at which age?
Show answer & explanation
Correct answer: C. In Colorado, 15 is the earliest age for a learner's permit, so plan your knowledge exam around that date. Study the official handbook, since permit questions come from it, and arrive with the required documents ready.
16. You want to park on a street just before a crosswalk. What minimum clearance do most handbooks require?
Show answer & explanation
Correct answer: B. A common handbook rule is 20 feet from a crosswalk so turning drivers and pedestrians can see each other. Parking closer hides people in the stripes. Twenty before the walk, then the hydrant's fifteen, is the pair testers expect.
17. If your car stalls on a railroad track, what does NHTSA say to do first?
Show answer & explanation
Correct answer: A. Official NHTSA railroad-crossing guidance says If your car stalls on a track, quickly get everyone out — even if you don’t see a train coming. Run away from the tracks and your car to avoid being hit by flying debris. Call the number on the blue emergency notification system sign.
18. An ice-cream truck is stopped ahead and children are gathered around it. How should you drive past?
Show answer & explanation
Correct answer: C. Slow way down and cover your brake near children or a stopped ice-cream truck, because kids chase treats and forget traffic completely. Expect someone small to dart out. Around children, drive as if one already has.
19. How are pedestrians who are blind usually identified in the Colorado handbook?
Show answer & explanation
Correct answer: A. Colorado says people with limited vision are easily recognized by the white cane they carry and/or by their guide dog, and pedestrians have the right-of-way. Slow, yield, and do not crowd them into the curb.
20. Traffic ahead suddenly stacks up on a freeway. What is the safest speed choice?
Show answer & explanation
Correct answer: B. The posted limit is a maximum, not a target. In dense or slowing traffic you must drop to a speed that lets you stop in the space you can see. Basic speed law: do not drive faster than conditions allow.
21. You are delivering food to a house on an unposted residential street in Colorado. Unless a sign changes it, what speed limit applies?
Show answer & explanation
Correct answer: A. Unposted residential streets in Colorado carry a default limit of 30 mph. The rule exists so drivers can stop for the unexpected, like a car backing out of a driveway. When a sign is posted, obey the sign instead.
22. An emergency vehicle is coming up behind you with lights and siren on a two-lane street. What should you do?
Show answer & explanation
Correct answer: B. Pull to the right and stop, clearing the lane. If you are in an intersection, clear it first, then pull over. Do not slam-stop in the path. Lights and siren mean yield the road, not freeze in the middle.
23. Your 20-year-old cousin is the designated driver tonight in Colorado. To obey the zero-tolerance law, they must keep their BAC below what threshold?
Show answer & explanation
Correct answer: A. In Colorado, drivers under 21 violate the zero-tolerance law once their BAC reaches 0.02%. A true designated driver drinks nothing at all; that is the whole job, and it keeps every passenger legally and physically safe.
24. Where is the official Colorado driver handbook published?
Show answer & explanation
Correct answer: A. The DMV publishes the Colorado handbook for free. That book is the source the knowledge test is written from. Our questions are original study items grounded in those rules, not a substitute for reading the handbook.
25. What is the highest posted highway speed limit in Colorado?
Show answer & explanation
Correct answer: A. Colorado's highest posted highway limit is 75 mph. Most stretches are lower, and work zones or weather can cut it further. Do not assume every freeway in Colorado is signed at the state maximum.
26. At a crosswalk signal, what is the difference between the walking-person symbol and the raised-hand symbol?
Show answer & explanation
Correct answer: C. The walking-person symbol invites pedestrians to begin crossing, while the raised hand warns them not to start; a flashing hand means finish crossing if already in the street. Drivers should expect people in the crosswalk during these phases.
27. On its fastest highways, Colorado allows a top posted speed limit of which value?
Show answer & explanation
Correct answer: A. The highest speed limit in Colorado is 75 mph, and only certain highways are posted that high. Most roads carry lower limits, so drive by the signs in front of you, and slow down when conditions worsen.
28. Which pair of official NHTSA NDR codes records driving while a license is revoked versus suspended?
Show answer & explanation
Correct answer: A. Official 23 CFR 1327 Appendix A (NHTSA NDR) lists B25 Driving while license revoked and B26 Driving while license suspended as separate codes. The leftover temporary-versus-erased definition is state terminology; this nearby official national code pair is.
29. Without reading any words, what does a yellow, diamond-shaped sign tell you?
Show answer & explanation
Correct answer: C. Yellow diamonds are warning signs: they alert you to hazards or changing conditions such as curves, intersections, or merging traffic. They advise rather than order. Shape and color alone should make you lift off the gas.
30. What is parallel parking, according to the official CA handbook wording used nationwide?
Show answer & explanation
Correct answer: A. Official California Driver Handbook wording says Parallel parking is when you park in line with the road and other parked vehicles. State inch-from-curb finish numbers differ, so this leftover uses that nationally applicable definition instead of inventing a national inch rule.
