1. A signal on an entrance ramp changes from red to green and lets one vehicle at a time onto the highway. What should you do?
Show answer
Answer A: Stop on the red and go on the green, one vehicle for each green
A ramp meter spaces vehicles out so they join the highway one at a time instead of arriving as a group, and it is a traffic signal like any other.
-
2. What does Kentucky require when a driver approaching a stopped emergency vehicle cannot safely change lanes?
Show answer
Answer D: Slow down and continue with caution at a speed safe for conditions
Kentucky's Move Over law requires a lane change where it is safe, and where it is not, the driver must slow down and proceed with caution.
-
3. When no limit is posted, what is the speed limit on Kentucky interstate highways and parkways?
Show answer
Answer C: 65 miles per hour
The Kentucky Driver Manual lists 65 miles per hour as the speed limit on interstate highways and parkways, although the secretary of transportation may raise specific highways to 70.
-
4. A sign on a long downgrade points to a runaway vehicle ramp. What is that ramp for?
Show answer
Answer C: Trucks that have lost braking ability on the grade
A runaway ramp is an escape lane of loose material that stops a heavy vehicle whose brakes have overheated or failed, so it must always be left clear.
-
5. Two people drink the same amount of alcohol at the same time. Why might their blood alcohol concentrations differ?
Show answer
Answer C: Body weight, gender and food in the stomach affect the concentration
Smaller people and, on average, women reach higher concentrations from the same amount of alcohol, and an empty stomach speeds absorption. Counting drinks alone does not tell you your level.
-
6. An oncoming vehicle at night has its high beams on and you are being dazzled. Where should you look?
Show answer
Answer A: Toward the right edge of your lane
Looking toward the right edge line keeps you on course while sparing your eyes the worst of the glare. Slow down and do not retaliate with your own high beams.
-
7. You are leaving a freeway at an exit that has a deceleration lane. Where should you slow down?
Show answer
Answer C: After you have moved fully into the exit lane
Braking in a through lane surprises the traffic behind you, so you move into the exit lane at highway speed and then slow down inside it.
-
8. Beyond the liability limits, what must a Kentucky auto policy provide, and which vehicle is excused?
Show answer
Answer C: Basic reparations benefits, except when the insured vehicle is a motorcycle
A Kentucky policy must carry basic reparations benefits in addition to the minimum liability limits, and motorcycles are the exception.
-
9. A driver who has been drinking has two cups of strong coffee. What has changed?
Show answer
Answer D: The driver is more awake but just as impaired
Coffee can make a drinker feel alert, but nothing except time removes alcohol from the blood, so a wide awake drinker is still an impaired driver.
-
10. Why should the washer reservoir hold proper washer fluid rather than plain water in winter?
Show answer
Answer D: Water freezes and it leaves you with no way at all to clean the glass
Washer fluid contains antifreeze, so it still works in the cold, whereas water freezes in the reservoir and the lines.
-
11. On a divided highway you see a median opening marked for authorized vehicles only. May you use it to turn around?
Show answer
Answer D: No, those openings are for emergency and maintenance vehicles
Official crossovers are reserved for emergency and highway maintenance use; turning there puts a slow vehicle across high-speed traffic.
-
12. A snow squall cuts visibility to almost nothing while you are on a highway. What must you not do?
Show answer
Answer D: Stop in a travel lane and wait for the squall to blow through
A vehicle stopped in a lane in a whiteout is invisible until someone hits it. Slow gradually and keep moving until you can leave the roadway completely.
-
13. Lights set into the pavement along both edges of a crosswalk start to flash yellow as you approach. What do they tell you?
Show answer
Answer D: Someone is crossing and has to be given way
In-roadway warning lights flash only when a pedestrian activates the crossing, so a flashing pattern means somebody is in or entering the crosswalk.
-
14. A child in the back seat unfastens a seat belt while you are on the freeway. What should you do?
Show answer
Answer A: Pull off safely and refasten the belt
Turning or reaching back takes your eyes and hands off a high speed task, so leave the freeway or use the shoulder only if there is no exit, then fix the belt.
-
15. The red oil pressure warning light comes on while you are driving. What should you do?
Show answer
Answer C: Pull over safely as soon as possible and shut off the engine
Loss of oil pressure means the engine is no longer being lubricated and can be destroyed within minutes. Stop, shut down and check before restarting.
-
16. A pedestrian is crossing at a corner where no crosswalk is painted on the pavement. What is your duty?
Show answer
Answer A: Yield, because a legal crosswalk exists at the corner even without paint
Every intersection has a crosswalk whether or not it is marked, and drivers must yield to pedestrians crossing there.
-
17. A bike lane on your right is marked with a dashed line for the last stretch before the corner. What does that dashed section allow you to do?
Show answer
Answer D: Merge into the bike lane after checking, and turn right from there
The dashed section is where drivers are meant to merge into the bike lane before turning, which puts cyclists behind the vehicle instead of beside it.
-
18. You stop at the curb on a busy street to let passengers out. What should you tell them?
Show answer
Answer A: To get out on the curb side, away from traffic
Passengers should always leave on the side away from moving traffic, which keeps both them and the door out of the travel lane.
-
19. You are about to drive a rental car that you have never driven before. What should you do?
Show answer
Answer A: Adjust the seat and the mirrors and find the controls before moving off
Hunting for the wipers or the lights in traffic is a distraction, so learn the layout while the vehicle is stopped.
-
20. You are turning left from a two-way street onto a one-way street. Which lane should you enter?
Show answer
Answer C: The first lane open to traffic on the left side of the one-way street
Turn left from the lane closest to the center line and finish in the first available lane on the left of the one-way street, then change lanes if you need to.
-
21. You are already inside an intersection when you realize you should be in the lane beside you. What should you do?
Show answer
Answer C: Stay in your lane through the intersection and change lanes afterwards
Drivers in an intersection are watching for cross traffic and turning vehicles, so an unexpected sideways move there is easily missed.
-
22. Why should heavy objects in the passenger compartment be secured?
Show answer
Answer A: Because loose objects fly forward in a crash and can injure the people
Anything loose keeps traveling at the speed of the vehicle when the vehicle stops, so it strikes the occupants with great force.
-
23. You are in the right-hand of two left-turn lanes and the vehicle beside you starts to drift toward your lane during the turn. What should you do?
Show answer
Answer B: Slow slightly, keep to your own lane and give the other vehicle room
Drivers commonly drift wide in dual turn lanes, so hold your own line, ease off and leave space rather than racing or crowding the other vehicle.
-
24. You are in the right-hand lane of a multilane street and that lane becomes a right-turn-only lane ahead, but you want to go straight. What should you do?
Show answer
Answer B: Change into a through lane before you reach the markings for the turn lane
A lane-use arrow is a regulatory marking, so a driver who wants to continue straight has to leave that lane before it becomes a mandatory turn lane.
-
25. What do white lane lines painted between travel lanes indicate?
Show answer
Answer A: Traffic in the adjacent lane moves in the same direction as you
White markings separate lanes carrying traffic in the same direction and mark the right edge of the roadway.
-
26. At what breath alcohol concentration does a Kentucky ignition interlock device prevent the vehicle from being operated?
Show answer
Answer B: Above 0.02
The Kentucky Driver Manual states that the ignition interlock device prevents a driver from operating the vehicle if the breath alcohol concentration exceeds .02.
-
27. How much time does Kentucky give a driver to try to reach an attorney before a chemical test is administered?
Show answer
Answer B: At least ten minutes but not more than fifteen
Kentucky affords the driver an opportunity of at least ten and not more than fifteen minutes to contact and speak with an attorney before testing.
-
28. Enhanced reference location markers differ from ordinary mileposts in that they
Show answer
Answer B: carry the route number and a mileage figure to the tenth of a mile
An enhanced reference location marker adds the route designation and carries the mileage to a tenth, so the point named is far more precise than a plain milepost.
-
29. You have a green light and an ambulance with lights and siren enters the intersection against its red. What should you do?
Show answer
Answer B: Stop and let the ambulance go through
An emergency vehicle answering a call may cross against a red, and every other driver yields to it whatever their own signal shows.
-
30. What is a driver being warned about here?
Show answer
Answer B: The pavement ahead carries vehicles traveling in the opposite direction
Beyond this point vehicles come the other way on the same pavement, which commonly happens where a one-way section or a separated stretch comes to an end.
-
31. A driver ignores this sign and passes on the opposite side. What is the main risk?
Show answer
Answer B: Ending up on the wrong side of a divider, facing traffic coming the other way
The sign settles which side of a fixed divider is the legal one, so taking the other side sends the vehicle into the opposing stream or straight at the obstruction.
-
32. You brake hard on a wet road and need to steer around a stalled car. How do antilock brakes help you do that?
Show answer
Answer B: They stop the wheels locking, so the tires can still turn the vehicle
Locked wheels slide and cannot change direction. By preventing lockup the system lets you brake at full force and steer at the same time.
-
33. The driver of a slow farm vehicle moves partly onto the shoulder and waves you past. Who is responsible for the pass?
Show answer
Answer A: You are, so pass only if you can see that the road is clear
A courtesy wave is not a traffic control, and the driver who changes lanes is the one answerable for the maneuver.
-
34. Blue pavement markings are used together with white markings at
Show answer
Answer D: parking spaces reserved for people with disabilities
Blue supplements the white markings of accessible parking spaces, which is the only assignment blue has on the pavement.
-
35. What should you check on the hitch before towing a trailer?
Show answer
Answer B: That the coupler is locked and the safety chains are crossed underneath
The coupler must be latched and pinned, and the chains crossed under the tongue so they cradle it if the coupling lets go.
-
36. You stop behind another vehicle at a traffic light. How much space should you leave?
Show answer
Answer D: Enough to see where its rear tires touch the pavement
Seeing the rear tires on the road leaves room to steer around the vehicle if it stalls, and gives a cushion if you are struck from behind.
-
37. You are driving along a street lined with parked cars. What should you watch for?
Show answer
Answer B: Doors opening, vehicles pulling out and pedestrians stepping from between cars
Parked cars hide people and can move without warning. Keep as much space from them as you safely can and cover the brake.
-
38. A person in a wheelchair is traveling in the roadway because the sidewalk is blocked by construction. What should you do?
Show answer
Answer B: Pass slowly with plenty of room, or wait
A blocked sidewalk leaves the person no choice but the road, and a chair cannot move aside quickly, so pass wide and slow or wait for room.
-
39. A warning sign showing two children on a see-saw is posted beside a residential street. What does it mean?
Show answer
Answer D: A play area lies beside the road and children may run out
The playground sign warns that children are present next to the roadway and may enter it without looking, so drivers should cover the brake and slow down.
-
40. On a narrow two-lane road a line of vehicles has built up behind you. What is the safe and courteous action?
Show answer
Answer D: Pull into a turnout or a safe wide spot and let them go by
A slow vehicle holding up a queue invites risky passing; using a turnout clears the road without anyone having to take a chance.
