Show answer & explanation

Show answer & explanation

Show answer & explanation
Correct answer: Parallel to and within 12 inches of the curb
On a two-way roadway you must park parallel to the curb with your right-hand wheels within 12 inches of it (or as close as practicable to the right edge of the shoulder).

Show answer & explanation
Correct answer: A liability insurance policy

5. At a four-way stop, if two vehicles arrive at the same time, who has the right-of-way?
Show answer & explanation

At an all-way stop, the first vehicle to stop goes first. When two arrive at the same time, the driver on the left yields to the driver on the right.
6. When driving in fog, you should use:
Show answer & explanation
Correct answer: Low-beam headlights
Use low beams in fog. High beams reflect off the water droplets and bounce glare back at you, making it harder to see.
7. A motorcycle traveling in a lane is entitled to:
Show answer & explanation
Correct answer: The full width of the lane, the same as any other vehicle
Motorcycles have the same rights and duties as other drivers and are entitled to the full lane. Never try to share a lane by driving alongside a motorcycle.
8. What must you do at a steady red traffic signal?
Show answer & explanation
Correct answer: Come to a complete stop and remain stopped until the light turns green
A steady red light means stop completely behind the stop line or crosswalk and wait. You may turn right on red (or left from a one-way onto a one-way) only after a full stop and yielding, unless a sign prohibits it.
9. What is the maximum speed limit on rural interstate highways in Illinois?
Show answer & explanation
Correct answer: 70 mph
The maximum on posted rural interstate highways is 70 mph (outside the Chicago-area collar counties, where lower limits may apply to certain vehicles). Always obey the posted limit, which may be lower.
10. In a business or residential district, how far before a turn must you signal?
Show answer & explanation
Correct answer: At least the last 100 feet before the turn
In a business or residence district you must signal continuously during the last 100 feet before turning. Outside such districts (higher speeds) the requirement is 200 feet.
11. For a driver under age 21, Illinois has a zero-tolerance law, which means:
Show answer & explanation
Correct answer: Any trace of alcohol can lead to a license suspension
Under Illinois zero-tolerance law, a driver under 21 who is caught with any amount of alcohol in their system faces a driver’s license suspension.
12. What is the earliest age at which a teen may obtain an Illinois instruction permit?
Show answer & explanation
Correct answer: 15, but only while enrolled in an approved driver-education course
Under the Graduated Driver Licensing (GDL) program, a teen may get an instruction permit at 15 only when enrolled in an approved driver-education course, with parent/guardian consent, and after passing the vision and written tests.
13. You may not park within how many feet of a fire hydrant?
Show answer & explanation
Correct answer: 15 feet
It is illegal to stand or park a vehicle within 15 feet of a fire hydrant so firefighters can reach it in an emergency.

Show answer & explanation
Correct answer: A fine and suspension of your license plates and driving privileges
Operating an uninsured motor vehicle is an offense that brings fines and suspension of your registration (license plates) and driving privileges.
15. You want to turn left at an intersection with a green light (no arrow). What must you do?
Show answer & explanation
Correct answer: Yield to oncoming traffic and pedestrians before turning
On a solid green light, a left-turning driver must yield to oncoming traffic and pedestrians, turning only when there is a safe gap. A green arrow, by contrast, gives you a protected turn.
16. In rain, snow, or other bad weather, you should:
Show answer & explanation
Correct answer: Slow down and increase your following distance
Traction and visibility both drop in bad weather. Reduce speed and leave more space so you have time and distance to stop safely.
17. Before turning at an intersection, you should look carefully for motorcycles because:
Show answer & explanation
Correct answer: Their small size makes them easy to miss and hard to judge for speed and distance
A motorcycle’s narrow profile makes it easy to overlook and its speed hard to judge. Look twice — many car-motorcycle crashes happen when a driver turns across a motorcycle’s path.
18. A steady yellow traffic light means:
Show answer & explanation
Correct answer: The light is about to turn red — stop if you can do so safely
A steady yellow warns that the signal is about to turn red. Stop if you can do so safely; if you are already too close to stop, proceed through the intersection with caution.
19. What is the speed limit on most other (non-interstate) Illinois highways unless otherwise posted?
Show answer & explanation
Correct answer: 55 mph
On most highways, roads, and streets outside urban districts, the limit is 55 mph unless a different limit is posted. Certain four-lane divided highways may be posted at 65 mph.
20. Outside a business or residential district (on higher-speed roads), how far ahead must you signal a turn?
