About construction signs

Construction and work-zone signs are orange with black symbols. They mark temporary conditions — lane shifts, flaggers, reduced speeds — and fines are often doubled in work zones. Test questions focus on how to respond safely around workers and equipment.

Practice the rule this sign carries

  1. How should you drive through a sharp curve?

    • A. Enter the curve at full speed and brake mid-curve if needed
    • B. Slow down before the curve and hold steady through it
    • C. Accelerate mid-curve to generate centrifugal force for stability
    • D. Brake hard just before the curve's apex
    Show answer

    B. Slow down before the curve and hold steady through it — Brake before a curve — not during. Braking in a curve shifts weight, reduces rear tire traction, and can cause sliding. Enter at a safe speed, then maintain or gently accelerate through the curve.
