Traffic Signs, Signals, and Road Markings
This domain tests how well you read Kentucky's signs, signals, and pavement markings - the visual language that tells you who goes, how fast, and where you may pass.
Signs by shape and color
Octagon red = STOP; inverted triangle = YIELD; diamond yellow = warning; pennant yellow = no-passing zone; round yellow = railroad advance warning; crossbuck = railroad crossing. Regulatory signs are white rectangles with black or red legends. Work-zone orange means workers may be present and fines can double when workers are present.
Signals
A steady green means proceed if clear; it does not protect a left turn. A green arrow gives protected movement in that direction. A flashing yellow arrow means a permitted left turn - yield to oncoming traffic. Flashing red means stop, then proceed when safe; treat it as a stop sign. A dark signal is a four-way stop.
Pavement markings
Broken yellow center line: passing allowed when safe. Solid yellow: no passing from your side. Double solid yellow: no passing either direction. White lines separate same-direction lanes; a solid white edge marks the right edge. A shared center turn lane is marked with two-way left-turn arrows and is only for turning.
Worked example
You face a flashing yellow left arrow. A line of oncoming cars is approaching. Reasoning: the arrow permits the turn but does not protect it; you must yield to oncoming traffic and turn only when a safe gap exists. If the arrow were a steady green arrow, oncoming traffic would be stopped and you could proceed.
Traps
Assuming a green ball protects a left turn; using a shared center lane as a travel lane; treating a flashing red as a yield sign; and ignoring a solid yellow line when passing.
