About warning signs
Warning signs are diamond-shaped and yellow with black symbols. They alert you to hazards ahead — curves, intersections, crossings — so you have time to slow down. On the DMV written test, expect several questions asking what a specific warning sign means and what action it calls for.
Practice the rule this sign carries
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.
