Illinois DMV Cheat Sheet

Correct answer: An automatic administrative suspension that applies even before any criminal conviction

The statutory summary suspension is administrative: it takes effect automatically after a failed or refused test, independent of whether you are later convicted of the DUI.

Correct answer: Can still lose their license under the zero-tolerance law

Zero tolerance applies to every driver under 21. Any detectable alcohol — even far below 0.08 — leads to a suspension, whether or not a full DUI is charged.

Correct answer: Aggravated DUI, a felony

Certain DUIs — those causing serious injury or death, or repeat offenses — are charged as aggravated DUI, a felony with prison time and long-term license loss.

Correct answer: A Class A misdemeanor, with a driving-privilege suspension

If a Scott’s Law violation results in damage to another vehicle, it becomes a Class A misdemeanor and the driver’s privileges are suspended for 90 days to one year.

Correct answer: A Class 4 felony

When a Scott’s Law violation results in injury or death, it is charged as a Class 4 felony — the most serious tier of the Move Over law.

Correct answer: Three or more

A driver convicted of three or more point-assigned moving violations within 12 months is identified for review and possible suspension or revocation. (Drivers under 21 face review at two.)

Correct answer: The driver’s siblings, step-siblings, children, or stepchildren

The one-passenger-under-20 limit excludes the driver’s own siblings, step-siblings, children, and stepchildren — immediate family members do not count against it.

Correct answer: They fail that test and are barred from retaking the written test for 30 days

Illinois regulation says anyone caught cheating fails that portion and cannot retake the written test for 30 days. (There is no codified waiting period for an ordinary honest failure.)

Correct answer: Toward the curb

Facing downhill, turn the front wheels toward the curb. If the vehicle rolls, the curb blocks the front tire and stops it before it reaches traffic.

Correct answer: Away from the curb, so a roll-back lets the tire catch the curb

Facing uphill against a curb, turn the wheels away from the curb (toward the street). If the vehicle rolls back, the rear of the front tire settles against the curb and stops it.

Correct answer: A safety zone (a marked pedestrian refuge in the road)

Parking is prohibited between a safety zone and the adjacent curb, or within 30 feet of points on the curb opposite the ends of a safety zone, unless signs indicate otherwise.

Correct answer: It expands to require yielding to emergency vehicles with flashing lights whether they are stationary or moving

As of January 1, 2026, the duty to slow down and move over expands to cover emergency vehicles displaying flashing lights whether they are stationary or moving — not only stopped ones.

Correct answer: No — on a divided highway, traffic in the opposing roadway need not stop

When a physical median or barrier separates the roadways, oncoming traffic on the far side does not have to stop for the bus. On an undivided road (even a wide one with only a painted line), you must stop.

Correct answer: Exercise due care to avoid the pedestrian, even though the pedestrian should yield

Even when a pedestrian crosses outside a crosswalk (and is legally required to yield), the driver must still exercise due care to avoid hitting them, sound the horn if needed, and give warning.

Correct answer: 300 feet of the vehicle ahead

High beams must be dimmed within 300 feet of a vehicle you are following, because the glare reflects off its mirrors into the other driver’s eyes.

Correct answer: Grip the wheel firmly, ease off the gas, and let the car slow before pulling off the road

A blowout pulls the car toward the flat tire. Hold the wheel firmly, ease off the accelerator, and let the vehicle slow gradually before braking gently and steering off the road.

Correct answer: Get everyone out and move well away from the tracks, in the direction the train is coming from

Abandon the vehicle immediately. Get everyone out and walk toward the train at an angle away from the tracks, so flying debris after the collision moves away from you. A car is never worth your life.

Correct answer: A school zone or school crossing

The five-sided pentagon shape marks a school zone or school crossing. Slow down and watch for children when you see it.

Correct answer: Traffic is merging ahead — adjust speed and position to let vehicles merge

A merge warning sign alerts you that another lane of traffic is joining yours ahead. Adjust your speed and position to allow vehicles to merge smoothly.

Correct answer: It marks a motorist service such as gas, food, lodging, or a hospital

Blue signs give motorist-service information — rest areas, fuel, food, lodging, and hospitals. Brown signs, by contrast, mark recreational and cultural sites.

Correct answer: No passing zone

The horizontal-pointing pennant is the NO PASSING ZONE sign, posted on the left side of the road to mark the start of a zone where passing is prohibited.

Correct answer: Stop line — stop behind it for a signal or stop sign

A solid white stop line (or "limit line") marks where you must stop for a red light, stop sign, or crosswalk. Stop behind it, not on top of it.

Correct answer: A lane reserved for high-occupancy or specially permitted vehicles

A white diamond painted on the pavement marks a reserved lane — typically for high-occupancy vehicles (carpools) or other specifically permitted users. Signs post the occupancy rules and hours.

Correct answer: Look back for approaching bicyclists so you do not "door" one

Opening a door into the path of a bicyclist ("dooring") causes serious crashes. Check over your shoulder for bikes before opening a door toward traffic.

Correct answer: Not pass it — it may be stopped for a pedestrian you cannot see

Never pass a vehicle stopped at a crosswalk or intersection. It is likely yielding to a pedestrian who is hidden from your view.
