Below are 4 real sample questions from our Illinois road signs practice test bank. Every question in PassMyDMV cites the exact page and rule in the official Illinois manual so you understand the law behind every answer:

Sample Question 1 · Stop Sign Regulatory Official Illinois Manual · Chapter 11 · Page 71

A red octagonal sign with white letters means:

A. Come to a gradual stop
B. Make a complete stop and yield right of way Correct
C. Yield to pedestrians only
D. Slow down and proceed with caution

Why B. Make a complete stop and yield right of way is correct: A red octagonal (eight-sided) sign is a STOP sign. You must make a complete stop at the stop line, or before entering the crosswalk or intersection if there is no stop line. You must yield the right of way to pedestrians and approaching traffic. The octagon shape is exclusive to stop signs in traffic control. [Manual: Roadway Signs — Regulatory Signs, p. 71]

Manual excerpt (Official Illinois Manual · Chapter 11 · Page 71): “An eight-sided (octagon) sign tells you to always make a full stop at the stop line. If there is no stop line, stop before entering the crosswalk. If there is no crosswalk, stop before entering the intersection. Yield the right of way to pedestrians and approaching traffic.”

Sample Question 2 · All Way Stop Official Illinois Manual · Chapter 11 · Page 71

When you see an All-Way Stop sign at an intersection, what must you do?

A. Slow down and yield to vehicles on your right
B. Stop in all directions; first driver to stop has the right of way Correct
C. Stop only if another vehicle is approaching
D. Proceed slowly while looking both ways

Why B. Stop in all directions; first driver to stop has the right of way is correct: An All-Way Stop sign means there are STOP signs at each approach to the intersection. Traffic from all directions must stop. The first driver to stop is the first driver to go. Other drivers must wait their turn. You may see 3-WAY, 5-WAY, or ALL-WAY signs underneath the main stop sign. [Manual: Roadway Signs — Regulatory Signs, p. 71]

Manual excerpt (Official Illinois Manual · Chapter 11 · Page 71): “This sign means there are STOP signs at each approach to an intersection. Traffic from all directions must stop. The first driver to stop is the first driver to go. Other drivers must wait their turn.”

Sample Question 3 · Yield Sign Official Illinois Manual · Chapter 11 · Page 71

What does a three-sided red and white Yield sign tell you to do?

A. Speed up to merge with oncoming traffic
B. Stop completely at all times
C. Give the right of way to all vehicles and pedestrians before proceeding Correct
D. Proceed at your current speed if no traffic is visible

Why C. Give the right of way to all vehicles and pedestrians before proceeding is correct: A three-sided (triangle) Yield sign tells you to give the right of way to all vehicles and pedestrians before proceeding. You must slow down to a safe speed and stop if necessary. When stopping, do so at a marked crosswalk or before entering the intersection. Yield signs differ from stop signs because you do not always need to make a complete stop if the road is clear. [Manual: Roadway Signs — Regulatory Signs, p. 71]

Manual excerpt (Official Illinois Manual · Chapter 11 · Page 71): “The three-sided (triangle) sign tells you to give the right of way to all vehicles and pedestrians before proceeding. Slow down to a safe speed and stop if necessary.”

A. You should slow down before entering
B. You are not allowed to enter in that direction Correct
C. Entry is allowed during the day only
D. You may enter only if you yield to other traffic

Why B. You are not allowed to enter in that direction is correct: A 'DO NOT ENTER' sign is posted on one-way streets and other roadways where you are not allowed to enter. You may see this sign if attempting to enter an expressway ramp in the wrong direction. Red signs with white text are regulatory and must be obeyed. Ignoring a DO NOT ENTER sign is illegal and dangerous. [Manual: Roadway Signs — Regulatory Signs, p. 71]
