1. 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.
-
2. You come to a place where a storm has dropped a power line across the road ahead. What should you do?
Show answer
Answer B: Stop well back, keep everyone away from it and report it to the police
A downed line may be live and can energize the ground around it, so keep well clear and let the utility or the police handle it.
-
3. What is the correct sequence for shifting into a higher gear?
Show answer
Answer C: Roll off the throttle, squeeze the clutch, lift the lever, ease the clutch out
Closing the throttle as the clutch comes in, then easing the clutch out as the throttle is reopened, keeps the change smooth and the chassis settled.
-
4. A traffic signal ahead is showing a flashing red light. What does it require?
Show answer
Answer C: Stop completely, then go when the way is clear, as at a stop sign
A flashing red light has the same meaning as a stop sign: stop completely, yield to traffic and pedestrians, then proceed when it is safe.
-
5. You have just passed a large truck on the freeway. Why is it dangerous to pull back in front of it and then brake for your exit?
Show answer
Answer B: A loaded truck needs much more distance to stop than a car
A fully loaded tractor-trailer can need the length of a football field or more to stop from highway speed. Cutting in and braking leaves the driver no room to avoid hitting you.
-
6. You are driving in fog so thick that you can barely see the vehicle ahead. Which pavement marking is the best guide for staying in your lane?
Show answer
Answer A: The white edge line on the right side of the road
The right edge line keeps you positioned away from oncoming traffic and is easy to follow at low speed. Following tail lights closely tempts you to drive faster than you can see.
-
7. What actually lowers the amount of alcohol in a person's blood?
Show answer
Answer D: The passage of time
The body eliminates alcohol at its own steady rate, so only time reduces blood alcohol. Coffee or a cold shower may make a person feel more awake while still impaired.
-
8. You face a red light at an intersection that has no stop line and no marked crosswalk. Where must you stop?
Show answer
Answer C: Before entering the intersection
With no line and no crosswalk, the stopping point is the near edge of the intersecting roadway, close enough to see cross traffic but clear of it.
-
9. A SHOULDER DROP OFF sign warns that
Show answer
Answer B: there is a step down from the pavement to the shoulder
The sign is used where the edge of the pavement stands several inches above the shoulder, which can grab a wheel and pull the vehicle sideways.
-
10. On traffic control devices, the color green shows direction to a destination and also shows
Show answer
Answer C: that a movement is permitted
Green carries two assignments: guidance toward destinations, and the idea that the movement shown is allowed, as on a green arrow.
-
11. What is the driver expected to do after passing this sign?
Show answer
Answer A: Begin slowing so that a complete stop can be made at the intersection ahead
It is used where the control at the intersection stays hidden until late, so braking should begin here rather than at the stop line.
-
12. A small plate under a stop sign reads CROSS TRAFFIC DOES NOT STOP. What is it telling you?
Show answer
Answer D: Traffic on the cross street is not required to stop at all
The plate warns that the other road is uncontrolled, so you must wait for a gap instead of expecting anyone to take turns with you.
-
13. When is a driver or rider most likely to need hand and arm signals instead of the vehicle turn signal lamps?
Show answer
Answer D: When the lamps have failed or cannot be seen because of glare or a load
Hand and arm signals replace or reinforce the lamps whenever the lamps do not work or cannot be seen clearly by other road users.
-
14. Why is a sign reading BRIDGE ICES BEFORE ROAD worth heeding even when the road itself is merely wet?
Show answer
Answer C: Cold air passes under a bridge as well as over it
A bridge deck loses heat from below as well as above, so it can be frozen while the road on either side of it is only wet.
-
15. What does a marked crosswalk tell a driver approaching a corner?
Show answer
Answer D: Where pedestrians are expected to cross and must be given way
Crosswalk markings show pedestrians where to cross and warn drivers to yield to anyone using the crossing.
-
16. At the scene of a crash you were part of, what are you required to do besides stopping?
Show answer
Answer B: Give your name, your address and vehicle details, and help anyone who is hurt
Every state requires drivers involved in a crash to identify themselves and to render reasonable aid to anyone injured.
-
17. A yellow diamond reading DIP warns a driver about
Show answer
Answer A: a short, sharp depression in the road surface
A dip is an abrupt low point that can jolt a vehicle or scrape its underside, so speed should be reduced before reaching it.
-
18. Why is standing water across a road dangerous even when it looks shallow?
Show answer
Answer B: It can hide a washed out roadbed, a deep hole or a missing cover
You cannot see the surface under the water, and floods commonly wash the roadbed away or lift covers off drains.
-
19. You are stopped at a red light waiting to turn right where the turn is allowed. Besides traffic from the left, what must you check?
Show answer
Answer D: Both crosswalks, and anyone approaching along your right side
A right turn on red crosses the crosswalk in front of you and enters the one on the cross street, and cyclists often approach along your right.
-
20. You are joining a highway from a short ramp that has no acceleration lane. What should you do?
Show answer
Answer A: Stop or slow at the end of the ramp and wait for a safe gap
Without an acceleration lane there is no room to match speed, so you must yield at the end of the ramp and enter only when a gap allows it.
-
21. 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.
-
22. Two drivers each have three drinks, one over three hours and one in half an hour. What is the difference?
Show answer
Answer C: The fast drinker reaches a higher peak level
The liver removes alcohol at a steady rate, so drinking faster than the body can clear it pushes the blood alcohol level much higher.
-
23. You are passing a line of slow traffic in the lane beside you and you notice a gap in that line ahead. What should you expect?
Show answer
Answer A: A vehicle may pull out of that gap into your lane
A gap in a slow line is an invitation to any driver waiting to turn out of a side street or to change lanes, and they are looking at the gap rather than at you.
-
24. You are driving in the left lane at the posted speed limit and a line of vehicles has built up behind you. What should you do?
Show answer
Answer D: Move into a lane on your right when it is safe and let the traffic behind go by
Most states require traffic moving slower than the flow to keep right and reserve the left lane for passing, so a driver holding up a line of vehicles should move right when it is safe rather than block the lane.
-
25. You have entered a work zone where crews are working close to the open lane. What should you do?
Show answer
Answer A: Slow down and be ready for workers and machines
Workers and equipment cross the open lane without warning in a work zone, so reduced speed and attention on the road ahead are what keep them safe.
