Wisconsin Road Signs Cheat Sheet.
The night-before summary, built like the exam.

The Numbers to Remember

• Knowledge test: 50 questions total.
• Passing standard: 80% correct — that's 40 of 50 on the knowledge test.
• A separate road signs section is graded on its own within the exam structure, so sign identification can't be skipped or made up elsewhere.
• Administered by WisDOT (Wisconsin Department of Transportation, Division of Motor Vehicles).
• There's no partial credit and no curve — every question counts the same toward the 80% line.

Sign Shapes at a Glance

• Red octagon — Stop, full stop every time, no exceptions.
• Red/white triangle — Yield, slow and give way.
• Yellow diamond — General warning ahead: curve, merge, narrow bridge, crossing.
• Yellow pentagon — School zone or school crossing.
• Round sign — Railroad crossing, always.
• White rectangle, black text — Regulatory rule (speed limit, turn restriction, one-way).
• Green — Guide/direction signage, exits and distances.
• Orange — Construction and work zones.
• Blue — Services: hospitals, fuel, rest areas.

Right-of-Way in One Breath

• Uncontrolled intersection: first vehicle to arrive goes first; simultaneous arrival, yield to the driver on your right.
• Four-way stop follows the same first-in, first-out logic.
• Left turns yield to oncoming traffic and to pedestrians before completing the turn.
• Always yield to pedestrians in crosswalks, whether marked or unmarked.
• Yield to traffic already circulating in a roundabout before entering it.
• Pull to the right and stop for emergency vehicles running lights and sirens.

Top Traps

• The posted speed limit is a ceiling, not a target — rain, fog, snow, or heavy traffic can require going slower than posted.
• High beams in fog make visibility worse, not better; switch to low beams.
• Bridges and overpasses ice before the rest of the road because cold air circulates on both sides.
• Reduced limits in school and construction zones apply whether or not workers or children are visible right now.
• Refusing a lawful sobriety test carries its own automatic license consequence, separate from any impairment charge.
• Zero-tolerance alcohol thresholds are far lower for drivers under 21 than for adult drivers.
• Sign questions reward shape-and-color recall speed — don't wait to read the fine print if the shape already told you the category.

Run through this list once the night before, then take one more full practice round. If you're clearing 90%+ on practice, you have real margin above the 80% pass line for test-day nerves.
