15 mph
45 mph
35 mph

Arm waving out the window
Left arm bent upward at the elbow
Left arm extended horizontally out of the driver's window
Left arm bent downward at the elbow

From sunset to sunrise or when visibility is less than 1,000 feet
Between noon and 2 PM
Only on rural roads
Only when the road is wet
Illinois law requires headlights from half an hour after sunset to half an hour before sunrise, or anytime visibility is under 1,000 feet. This improves safety in low-light conditions. Always turn on lights in rain or fog.

Under 5 years old
Under 12 years old
Under 8 years old unless over 4'9" tall

What is required before making a legal right turn on red in Illinois?
Come to a complete stop and yield to all traffic and pedestrians
Honk to alert pedestrians then turn

You have passed the other vehicle's front bumper
You can see the entire front of the passed vehicle in your rearview mirror
The road ahead looks clear
You signal and begin to drift right
Return to your lane only when you can see the front bumper of the passed car in your rearview mirror. This ensures you have enough space. Signal and check mirrors and blind spots before merging.
What does a flashing red traffic signal mean?
Stop, then proceed when safe
Stop only if other traffic is present
Slow down and proceed with caution

The largest vehicle
The fastest vehicle
The vehicle on the left
The first vehicle to reach and stop at the intersection

What does a solid double yellow line on the roadway indicate?
Passing allowed for both directions
Passing allowed only for left traffic
Center turn lane only
No passing in either direction
Double solid yellow lines separate travel in opposite directions and prohibit passing in either direction. They mark areas where passing is unsafe. Cross only to turn into driveways if permitted.

2/32 of an inch
4/32 of an inch
3/16 of an inch
1/32 of an inch
Illinois law requires a minimum tire tread depth of 2/32 inch for passenger vehicles. Proper tread ensures traction and safe braking. Check tread wear indicators regularly.
How should you park when facing uphill on a two-way street with a curb?
Angle wheels toward the street
Leave wheels straight
Turn your front wheels away from the curb and let the car roll back
Turn your wheels toward the curb
When parking uphill with a curb, turn your wheels away from the curb; if brakes fail, the car will roll back into the curb, stopping it. Always set the parking brake. This prevents runaway vehicles.
When driving on the shoulder to pass another vehicle, you are:

Violating the law
Allowed if the shoulder is wide

At approximately what speed does hydroplaning start to occur?
35 mph in standing water
5 mph on puddles
60 mph on wet roads

If you refuse a chemical test when arrested for DUI, the implied consent law means:
You cannot be arrested
Your license will be suspended for at least one year

At a controlled intersection with green arrow, you should:
Yield to oncoming traffic
Stop first then turn

Cheat Sheet

  1. Traffic Sign Recognition -

    Master the shapes, colors, and meanings of Illinois signs for the rules of the road illinois test. For example, an octagon always means STOP and a diamond warns of hazards; learning that red means "stop or prohibition" and yellow means "caution" will speed your responses. Use the mnemonic "Red Rules, Yellow Yields, Green Go" to lock these in memory.

  2. Speed Limits & Safe Following Distance -

    Know Illinois default speed limits - 30 mph in business/residential, 20 mph in school zones, and 55 - 70 mph on highways - before tackling any rules of the road illinois practice test. Apply the three-second rule by picking a fixed landmark and ensuring three seconds pass between the vehicle ahead and yours; double that in rain or fog. The Illinois Secretary of State recommends this formula to help prevent rear-end collisions.

  3. Right-of-Way Rules -

    Review who goes first at various intersections; at 4-way stops, the first vehicle to arrive proceeds, and when in doubt, yield to the right. Always yield to pedestrians in crosswalks and to emergency vehicles with flashing lights - this is emphasized in the state of Illinois rules of the road practice test materials. Remember "First In, First Out" at multi-stop intersections to avoid confusion.

  4. Lane Usage & Passing Guidelines -

    Understand when passing is legal: always pass on the left, never cross a solid yellow line, and avoid passing within 100 feet of intersections or railroad crossings. Illinois official guides stress staying in the right lane except to pass or turn left on multi-lane roads. A quick check of mirrors and blind spots plus signaling at least 100 feet before lane changes is a winning formula for both the exam and safe driving.

  5. DUI & Impaired Driving Laws -

    Memorize Illinois's .08% BAC limit for drivers 21 and older, and the zero-tolerance policy for those under 21 - key facts on the illinois rules of the road practice test. Administrative license revocation kicks in at .08% and above, so knowing your body's alcohol elimination rate (about one drink per hour) can keep you compliant. The Secretary of State's official pamphlet offers charts to estimate your BAC based on weight and drink count.
