This chapter covers the meaning of traffic signals (red/yellow/green, flashing signals, arrows), the categories of traffic signs (warning, regulatory, guide) with their standard colors and shapes, and pavement markings that show lane rules and no-passing zones.
The most-tested concepts are what each signal color/pattern requires you to do (including flashing red vs. flashing yellow), the meaning of sign shapes and colors as a quick-recognition system, and reading pavement line colors/patterns (solid vs. broken, yellow vs. white) to know when passing or lane changes are allowed.
A common mistake is confusing a flashing red light (treat like a stop sign) with a flashing yellow light (just slow down and proceed with caution), and misreading which side of a double line you're allowed to cross.
What's the difference between a flashing red light and a flashing yellow light?⌄
A flashing red light means stop completely, just like a stop sign, and go only when it's safe; a flashing yellow light means slow down and proceed carefully without a full stop.
How do sign shapes help you recognize them quickly?⌄
Each shape is reserved for a category — for example an octagon is used only for stop signs and a triangle only for yield signs — so you can recognize the type of instruction even before you can read the text.
What does a solid yellow line on my side of the center line mean?⌄
It marks a no-passing zone — you should not cross it to pass another vehicle, while a broken/dashed line means passing is allowed if it's safe to do so.
