1What is the shape of a stop sign in Illinois?
A.Triangle
B.Octagon (eight sides)
C.Diamond
D.Round
Explanation: A stop sign always has eight sides (an octagon) and is red with white lettering. The unique shape lets drivers recognize it even when it is partially blocked by snow or branches. When you see one, you must come to a complete stop.
2What does a red traffic signal mean?
A.Slow down and proceed with caution
B.Stop completely and remain stopped until the light turns green
C.Stop only if pedestrians are present
D.Yield to oncoming traffic, then continue
Explanation: A steady red light means you must come to a complete stop behind the stop line, crosswalk, or intersection and stay stopped until the light turns green. After stopping, you may turn right on red where it is not prohibited, once it is safe and you have yielded to traffic and pedestrians.
3A yellow traffic signal light means:
A.Speed up to clear the intersection before the light turns red
B.The light is about to turn red; stop if you can do so safely
C.Stop and wait for a green light before moving
D.The signal is out of service; treat it as a stop sign
Explanation: A steady yellow light warns that the signal is about to turn red. You should stop before entering the intersection if you can do so safely. If you are already too close to stop safely, proceed through the intersection with caution.
4What does a yellow diamond-shaped sign generally indicate?
A.A regulatory law you must obey
B.A warning of a hazard or change in road conditions ahead
C.A destination or route guide
D.A school zone only
Explanation: Yellow diamond-shaped signs are warning signs. They alert drivers to possible hazards or changes ahead, such as curves, intersections, merging traffic, or slippery roads. They tell you to slow down and stay alert.
5An orange sign in a work area means:
A.A scenic point of interest is ahead
B.Construction, maintenance, or a work zone is ahead
C.A recreational area is ahead
D.A hospital is nearby
Explanation: Orange signs indicate construction and maintenance work zones. They warn drivers to slow down, expect workers and equipment, and be ready for changed traffic patterns. Fines for traffic violations are increased in Illinois work zones.
6What does a flashing red traffic signal mean?
A.Proceed without stopping
B.Come to a complete stop, then proceed when it is safe
C.Slow down but do not stop
D.The intersection is closed
Explanation: A flashing red light means the same thing as a stop sign. You must come to a complete stop, yield to traffic and pedestrians, and proceed only when it is safe to do so.
7A flashing yellow traffic signal means:
A.Stop completely before entering the intersection
B.Slow down and proceed through the intersection with caution
C.The signal is broken and should be ignored
D.Yield only to pedestrians
Explanation: A flashing yellow light means slow down and proceed through the intersection with caution. It warns of an intersection or hazard that requires extra care, but it does not require a full stop.
8What does a solid yellow line on your side of the center of a two-way road mean?
A.Passing is allowed at any time
B.Passing is not permitted from your side of the road
C.The road is one-way
D.You may park along the line
Explanation: A solid yellow line on your side of the centerline means you may not cross it to pass another vehicle. Yellow lines separate traffic moving in opposite directions. A broken yellow line on your side means passing is permitted when safe.
9White lane lines on a roadway are used to:
A.Separate traffic moving in opposite directions
B.Separate lanes of traffic moving in the same direction
C.Mark the edge of a railroad crossing
D.Indicate a no-parking zone
Explanation: White pavement lines separate lanes of traffic traveling in the same direction. A broken white line means you may change lanes when it is safe; a solid white line discourages or prohibits lane changes.
10A triangular sign pointing downward means:
A.Stop
B.Yield the right-of-way
C.Do not enter
D.No U-turn
Explanation: A downward-pointing triangle is a yield sign. It means you must slow down, be ready to stop, and give the right-of-way to traffic and pedestrians in or approaching the intersection or roadway you are entering.
