About the Maryland CDL lights and signals test
Being seen and signaling clearly is a safety essential, and the Maryland CDL pre-trip lights signals test checks that part of your inspection. This 2026 drill covers confirming that headlights, taillights, brake lights, turn signals, marker lights, and reflectors are all present, clean, and working before you pull out onto a Maryland road.
You will rehearse the routine of switching each light on and walking around to verify it, checking that the four-way flashers function, and making sure lenses are the right color and free of cracks. Confirming your lights and signals is a quick step that keeps a commercial vehicle visible and legal, and examiners expect you to know exactly what to check.
Because pre-trip question counts vary by jurisdiction, the definitive number is in your current Maryland CDL Manual. Drill this lights-and-signals routine until the full check is automatic, and you will round out another corner of your CDL pre-trip inspection preparation.
Every question traces back to the Maryland CDL Manual - skim the right-of-way and signs chapters before your retake.
