Pennsylvania Road Signs and Their Meanings

Eighteen questions. That is the entire Pennsylvania knowledge test — the shortest car exam of any state on this site — and fifteen of them have to be right, which leaves room for exactly three wrong answers. PennDOT sums up what those eighteen questions measure in one line, and it puts signs at the front of it: the Knowledge Test will measure your knowledge of traffic signs, Pennsylvania's driving laws and safe driving practices. A short test is not a soft one. It is a test where every single question carries more than five percent of your result, and where three unlucky guesses about a sign you half-remember is the whole margin gone.

Pennsylvania sets no separate standard for the sign questions, and never breaks the eighteen down by subject at all. There is one score, fifteen of eighteen, stated in the manual in two flat sentences. Access, by contrast, PennDOT documents in detail: the test comes in written and audio format in eighteen languages, English among them, at every driver license center in the commonwealth. Voice tests, for anyone who would rather have the questions read aloud than read them, are offered at all centers on request. Applicants who use sign language can specify which system they need — ASL, Pidgin Sign Language, Signed Exact English, or an oral interpreter who reads lips — and once an interpreter has been hired, PennDOT calls back to confirm the test date.

Chapter 2 of the PA Driver's Manual is titled Signals, Signs and Pavement Markings, and it is where every published Pennsylvania sign question in this bank comes from. The chapter opens on signals, moves through signs — regulatory from page 10, warning from page 13, guide from page 19 — and closes on pavement markings. Its position in the book is itself a choice: Chapter 2 comes before Chapter 3, Learning to Drive, so PennDOT teaches you to read the road before it teaches you to operate a car on it.

What makes Pennsylvania's sign chapter unusual is that it rarely stops at what a sign means; it tells you what to do with the car. The entry for a right-bending curve does not merely report that the road curves — it says to slow down and position your vehicle slightly to the right of the center of your lane. Sharp turns get slow down substantially. The entry for a large one-direction arrow says the road ahead changes direction at an extreme angle, then tells you to slow down as much as you would to make a turn at an intersection — a comparison you can act on, rather than a definition. There is even an entry for the sign that identifies curves where trucks traveling at excessive speeds have the potential to roll over. Knowing that a diamond means sharp right turn is only half of what the page it came from actually asks of you; the other half is a lane position.

35 published Pennsylvania road-sign questions, each with an explanation and a citation to the handbook section it came from.
