Pennsylvania exam answer

How many answers does Pennsylvania require?

Pennsylvania's non-commercial knowledge test contains 18 multiple-choice questions, and PennDOT requires at least 15 correct answers. That is approximately 83%. This independent practice offers diagnostics, adaptive review, broader mixed sessions, and source-linked explanations; it is not the PennDOT examination or an official question bank.

Sample question · no JavaScript needed

A traffic signal is completely dark in Pennsylvania. How should you treat the intersection?

As a four-way stop
As a green light for the larger road
As a yield only for left turns

Answer: A — Treat it as a four-way stop. Every approach follows the stop-and-right-of-way process until the signal operates again.

Choose a practice mode

Start with coverage, then target the rule.

Use a diagnostic, adaptive weak-rule practice, a 20-question mixed set, or a longer exam-style practice session. Pennsylvania's official test has 18 questions; the practice lengths here are learning tools, not replicas.

What this set covers

Pennsylvania rules, including Steer Clear and school-zone details.

The state set covers red and dark signals, 15 mph school zones, STOP and YIELD behavior, school-bus distances and divided-highway exceptions, emergency vehicles, Steer Clear, railroad crossings, work-zone flaggers, pedestrians, trucks, funeral processions, seat belts, and distractions.

Shared signs and signal-image questions use site-authored diagrams based on public-domain FHWA designs. Pennsylvania-specific answers remain tied to the current PennDOT online manual.
