The Permit Test
Curve Ahead (MUTCD W1-2 sign)

Curve Ahead

warning sign · diamond · yellow

The road bends ahead — gentler than a turn, but enough to warrant easing off, especially at night or in rain.

Visual breakdown
Yellow diamond with a smoothly bending arrow.
Shape recognition
Rounded sweep in the arrow = curve; compare the hard elbow of the sharp-turn sign.
Color recognition
Yellow warning; watch for chevrons marking the curve itself as you enter.
Memory trick
Round arrow, rolling speed — set your speed before the curve, throttle steady through it.
Real-world example
A highway curve posted with a 45 advisory: brake on the straight, then hold light throttle through the arc for maximum grip.
Common mistakes
Confusing curve (rounded) with turn (angular) on shape-identification questions — the exam loves this pair.
Quick recall method
Rounded arrow = curve; angular arrow = turn.
