Curve Sign

Curve signs warn of bends, with the arrow shape indicating severity (gentle vs sharp/hairpin). Excess speed into a curve is a leading single-vehicle crash cause.

Meaning

Red-bordered white triangle with a curved arrow (gentle bend or sharp/hairpin).

Required driver response

Reduce speed appropriately for the severity of the bend.

Question patterns

  • “What does this sign mean?” — recognition of meaning.
  • “What must you do when you see this sign?” — required response.
  • Distractor trap: confusing a gentle curve with a sharp curve, or with a lane-shift sign.
