1. At 45 mph you look at a navigation screen for four seconds. Roughly how far do you travel unseeing?
Show answer
Answer D: About 260 feet
At 45 mph you cover roughly 66 feet a second, so four seconds on a screen is around 260 feet of road that you never looked at.
-
2. A sign showing a walking figure inside a red circle with a diagonal slash stands at the start of a bridge. What does it mean?
Show answer
Answer C: People on foot may not use that roadway
The no pedestrians sign excludes people on foot from that roadway altogether, which is common on high-speed bridges and freeways.
-
3. A bicyclist is riding around a single-lane roundabout in the middle of the lane as you wait to enter. What is your duty?
Show answer
Answer C: Yield to the bicyclist just as you would to a car
A bicyclist using the roundabout is traffic like any other vehicle and has the same claim to the circulating lane.
-
4. You are in the acceleration lane and the gap you were aiming for is now beside you. What is the best adjustment?
Show answer
Answer A: Change your speed a little to line up with a gap, then merge smoothly
The acceleration lane is for matching both the speed and the position of a gap, and small speed adjustments are what line the two up.
-
5. You are parking facing uphill on a street with a curb. What is the correct wheel position?
Show answer
Answer B: Turn the front wheels away from the curb and let the vehicle roll back until a tire touches it
Facing uphill the vehicle would roll backward, so the wheels point away from the curb and the tire is rested against it to act as a block.
-
6. Your low beams light about 250 feet of road, but at your speed you would need more than that to stop. What is that called?
Show answer
Answer D: Overdriving your headlights
When your stopping distance is longer than the stretch of road your headlights show, you cannot react to anything you finally see. Slow down until you can.
-
7. You are traveling at the same speed as a vehicle in the next lane, just behind its rear door. What should you do?
Show answer
Answer B: Change your speed so that you leave that driver's blind spot
That position is the classic blind spot. Slow slightly or move ahead so the other driver can see you before deciding to change lanes.
-
8. You are using the parking brake to slow a vehicle whose brakes have failed. How should you apply it?
Show answer
Answer D: Gradually, holding the release so you can let it off if the rear slides
The parking brake works on two wheels only, so applying it hard can lock them and spin the vehicle. Keep the release held so you can back it off instantly.
-
9. You turn the wheel but the front of the vehicle keeps sliding straight ahead on a slippery road. What should you do?
Show answer
Answer C: Ease off the accelerator and reduce the steering angle until the front tires grip again
A front-wheel skid means the tires are asking for more grip than the surface can give. Less speed and less steering angle let them regain traction.
-
10. You want to turn left across the oncoming lane into a shopping center driveway. Who must you yield to?
Show answer
Answer B: Oncoming traffic and anyone using the sidewalk
A left turn into a driveway crosses both the oncoming lane and the sidewalk, so you give way to traffic and to pedestrians before completing it.
-
11. How much more energy must your brakes absorb if you double your speed?
Show answer
Answer D: About four times as much, since energy rises with the square of speed
Kinetic energy grows with the square of speed, so twice the speed means about four times the energy and a far longer braking distance.
-
12. A curb sign reads 2 Hour Parking, 8 AM to 6 PM, Monday to Saturday. When may you stay longer than two hours?
Show answer
Answer A: Outside those hours and on Sundays
A time limit applies only during the days and hours printed on the sign; outside them the ordinary parking rules apply.
-
13. Two solid yellow lines are painted down the center of a two-way road. What do they mean?
Show answer
Answer B: Traffic in neither direction may cross them to pass
A double solid yellow line marks a no-passing zone that applies to traffic traveling in either direction.
-
14. How much following distance should you keep behind a motorcycle?
Show answer
Answer C: At least three to four seconds
A motorcycle can slow or stop very quickly and is easily upset by a surprise, so allow three to four seconds instead of the usual car gap.
-
15. A power line has fallen across your vehicle after a crash. What should you do?
Show answer
Answer C: Stay inside and wait for utility workers unless fire forces you out
The vehicle body may be energized, and touching it and the ground at the same time can be fatal. If you must leave because of fire, jump clear with both feet together and shuffle away.
-
16. You correct a rear wheel skid and the back of the vehicle swings the other way. Why?
Show answer
Answer D: You steered too far, so be ready to correct back the other way
Over correcting sends the tail past straight and starts a second skid the opposite way. Steer smoothly and be ready to unwind the correction.
-
17. Where does Colorado require signs warning of an automated speed enforcement camera to be placed?
Show answer
Answer B: At least 300 feet before the camera and before the zone it covers
Colorado requires signage at least 300 feet before an area where an automated vehicle identification system is in use and 300 feet before an active camera.
-
18. Traffic in a work zone is down to one lane in each direction, separated by a temporary double yellow line. May you pass?
Show answer
Answer C: No, temporary markings prohibit passing just as permanent ones do
A temporary marking has the same legal force as a permanent one, and a work zone is the last place with room to spare for an overtaking vehicle.
-
19. A vehicle is sitting in your blind spot and you need to change into that lane. What should you do?
Show answer
Answer B: Adjust your speed to open a clear gap, then check again and move over
Changing your speed either drops the other vehicle behind you or lets it move ahead, which turns the blind spot back into open space.
-
20. You are waiting in a left-turn lane at a green light when a fire engine with lights and siren comes toward you in the oncoming lanes. What should you do?
Show answer
Answer D: Hold your position and let the fire engine pass
Turning across the path of an approaching emergency vehicle is exactly what you must not do; stay put until it has gone by.
-
21. On a multi-lane street, a yield line is painted well back from an unsignalized crosswalk rather than right at it. Why?
Show answer
Answer D: So drivers in the other lanes can see the pedestrian
Setting the yield line back keeps a stopped vehicle from hiding a crossing pedestrian from drivers in the next lane, which is a common cause of these crashes.
-
22. You are traveling at 55 mph and see a vehicle ahead moving at about 15 mph. What is the hazard?
Show answer
Answer A: You reach it far sooner than you expect
At a 40 mph difference you cover the gap in a few seconds, which is why drivers strike slow vehicles they saw in plenty of time.
-
23. A child seat was in the car during a moderate crash. What should be done with it?
Show answer
Answer A: Replace it, because a seat that has been through a crash may be weakened
Crash forces can damage a seat in ways you cannot see, so a seat involved in anything but the mildest crash is replaced.
-
24. You are approaching a horse and rider on a country road. What about your horn?
Show answer
Answer C: Do not sound it at all, because the noise can frighten the animal
A startled horse is dangerous to its rider and to you, so pass wide and slow and leave the horn alone.
-
25. At roughly what speed can hydroplaning begin when a lot of water is lying on the road?
Show answer
Answer C: At speeds as low as about 35 mph
With enough water and less than perfect tread, a tire can start to ride on the water at around 35 mph, well below normal highway speeds.
