Shape and color tell you what a sign does before you can even read it. Learn these six and most sign questions answer themselves.
Full stop before the line, crosswalk or intersection. Then proceed when clear.
Slow, be ready to stop, and let cross traffic and pedestrians go first.
Something ahead needs your attention: a curve, a merge, animals, a narrow bridge.
School zone or crossing. Reduced limit (15–20 mph) when active.
Speed limits, one-way, no turn. Regulatory: breaking it is a violation.
Workers and equipment ahead. Fines double in an active work zone.
Yellow separates opposing traffic; white separates same-direction lanes. Broken = you may cross when safe. Solid = stay put.
Flashing red = stop sign. Flashing yellow = proceed with caution.
