Warning, Construction & Information SignsStandalone practice
On a two-lane road, you follow a slow truck and see this yellow diamond sign with a black arrow that curves to the left. What should you do?
Correct answer: Slow down, keep right, and do not pass until after the curve
Why
Warning signs are yellow diamonds that tell you about a hazard ahead, so you have time to change your speed or position. Slow down before the curve, so that you can steer through it without hard braking. A driver who passes near a curve cannot see oncoming traffic in time to prevent a head-on crash.
