1. Double curve

A double curve is a warning sign that tells drivers the road ahead has two back-to-back curves—first one way, then the other. It’s meant to prepare you to slow down and stay alert, as the road won’t be straight for a short distance. Double curves can be tighter than they appear, and the second curve can surprise you if you're going too fast—always reduce speed when you see the sign.

  • There are two sharp bends ahead.
  • The first curve may go left or right, depending on the sign.
  • The second curve comes immediately after the first.
  • Usually found in hilly, rural, or winding roads.
  • How to Drive Through a Double Curve:
    • Slow down before entering the first curve.
    • Steer smoothly through both turns.
    • Stay centered in your lane.
    • Avoid sudden braking or turning between the curves.
