Pennsylvania CDL Traffic Signals & Road Markings Test 2026

Traffic signals and pavement markings guide every mile you drive, and this Pennsylvania CDL signals and markings test confirms you read them correctly. The 2026 questions cover traffic lights and arrows, flashing signals, and what to do when a signal is dark, along with the lane lines, arrows, and crosswalks painted on the road itself.

You will review the difference between solid and broken lines and where passing is allowed, yellow versus white markings, stop lines and crosswalks, and the special markings at intersections and work zones. For a Pennsylvania CDL driver, honoring these signals and markings while managing a large vehicle through busy intersections is a core safety skill the exam expects you to have.

Signals and markings work hand in hand with signs to keep traffic orderly, so this topic rounds out your road-reading knowledge. When a 2026 practice question is unclear, check the signals and markings guidance in the Pennsylvania Commercial Driver's Manual, then drill again until every signal and line is instantly clear before your PennDOT general knowledge test.
