Maryland CDL School Bus Test common mistakes
Maryland CDL School Bus Test · Understand the traps and how to avoid them.
On the pre-trip walk-around, the candidate checks that the stop arm extends but never verifies that the red lights flash, that the crossing gate (if equipped) swings out fully, or that the bus's own hazard/amber warning lights activate before the stop arm deploys.
Candidates memorize the stop arm as a single item and skip the linked sequence: amber warning lights, stop arm out, red lights flashing. The Maryland skills test scores the stop arm as a system, and examiners watch for the light sequence, not just the arm.
What to do instead
Practice the stop-arm sequence aloud in order: activate the amber warning lights, open the door, confirm the stop arm extends fully, confirm the red student lights flash, and confirm the crossing gate lowers (if equipped). Rehearse until the light check is automatic, then repeat it on the actual bus used for testing.
During the pre-trip inspection, the candidate points at the emergency exits and says 'exits are good' without physically opening the side emergency door, testing the buzzer, or verifying that the rear emergency door opens from the inside and that the roof hatch releases.
Emergency exits feel obvious, so candidates rush them. But Maryland requires that the emergency door buzzer sound when the door is opened with the ignition on, and candidates often don't know the buzzer is a testable item.
What to do instead
Build a physical checklist: open the side emergency door and listen for the buzzer, open and close the rear emergency door from inside, release and reseat the roof hatch, and check that exit handles are labeled and unobstructed. Say each action out loud during practice so it becomes part of the script.
The candidate stops at the railroad crossing but does not open the door or window to listen, and does not announce that the bus must stop at least 15 feet but no more than 50 feet from the nearest rail.
Candidates confuse the school bus rule with the general CDL rule and treat the crossing as a rolling check. They also forget that the door must be opened to listen for an approaching train.
What to do instead
Memorize the school bus crossing procedure as a fixed sequence: stop 15 to 50 feet from the nearest rail, place the transmission in a lower gear, turn off the radio and fans, open the door and window, look and listen both ways, close the door, then proceed without shifting gears while crossing. Practice the stop distance with a marker so the 15-to-50-foot window becomes physical memory.
When unloading, the candidate releases students before confirming the bus is fully stopped, the parking brake is set, and the transmission is in neutral or park, and then does not count students as they exit or check that they have moved away from the bus before releasing the brake.
Unloading feels routine, so candidates skip the brake-and-gear step and the student count. Maryland scoring treats unloading as a supervised procedure, and a missed count or an early brake release is a critical error.
What to do instead
Rehearse a fixed unloading script: stop, set the parking brake, place the transmission in neutral or park, announce the stop, open the door, count students out loud as they exit, watch them move at least 10 feet from the bus or to a safe waiting point, then close the door and release the brake. Do the count out loud every practice run.
The candidate stops for a student but leaves the bus in gear or with the parking brake off, or fails to secure the bus before leaving the driver's seat to assist a student across the street.
Candidates focus on the student and forget the vehicle. Maryland requires the bus to be secured whenever the driver leaves the seat, and examiners look for the brake and gear check as a scored step.
What to do instead
Tie the action to the student: before opening the door to assist a student, set the parking brake, shift to neutral or park, and take the keys if leaving the bus. Practice the 'secure, then stand' order until it is automatic, and say it aloud during the skills test.
The candidate describes discipline as 'telling the principal' and cannot name the escalating steps: a verbal warning, a seat change, a written referral, and a report to the administrator, or cannot explain when to pull over and stop the bus for a serious disruption.
Discipline questions sound like common sense, so candidates answer with generalities. Maryland expects a defined escalation path and a clear rule for when a disruption requires stopping the bus in a safe location.
What to do instead
Learn a four-step ladder: verbal correction, seat reassignment, written referral to the school, and administrator notification. Add the safety override: if a student's behavior threatens safety, pull to a safe location, secure the bus, and radio dispatch before acting. Practice describing the ladder in order in one minute.
The candidate loads students without counting them, without confirming they are seated before moving, and without checking that students are clear of the danger zone before closing the door.
Loading is treated as the easy half of the run. Candidates skip the count and the seating check, and they close the door before confirming the doorway is clear.
What to do instead
Use a loading script: stop, secure the bus, open the door, count students as they board, confirm each is seated and facing forward, check the doorway and danger zone, then close the door and proceed. Practice the count out loud and have a partner stand in the danger zone so you learn to check it every time.
The candidate answers emergency evacuation questions by naming the exits but cannot state the order of actions: stop the bus, secure it, radio dispatch, assess the hazard, evacuate to a safe distance, account for students, and keep them together.
Candidates memorize exit locations but not the decision sequence, so they freeze when asked what to do first. Maryland scores the sequence, not just the exit list.
What to do instead
Memorize a six-step evacuation order: stop and secure the bus, notify dispatch, assess the hazard, choose the safest exit, move students at least 100 feet from the bus and upwind of a fire, then count and hold students together. Practice the order with a partner who asks 'what next' until it is fluent.
The candidate fails to check the bus for sleeping students at the end of the run, or cannot explain the child-check procedure, including walking the aisle and checking under seats.
The end-of-run check is easy to skip after a long route, and candidates underestimate how heavily it is scored. Maryland requires a physical walk-through, and a missed check is a serious safety failure.
What to do instead
Make the post-trip walk-through a fixed habit: park, secure the bus, walk the full aisle front to back, look under and between every seat, check the rear, and record the check. Practice it on every training run so it becomes automatic, and be ready to describe it step by step.
The candidate identifies the danger zone as 'around the bus' but cannot state its size, cannot explain that students must wait until the driver signals them, and does not check the mirrors before moving.
The danger zone is taught as a concept, not a measurement, so candidates give vague answers. Maryland expects a specific distance and a specific signaling procedure.
What to do instead
Memorize the danger zone as the area within 10 feet around the bus, with the front and rear blind spots larger. Learn the signal rule: students wait until the driver nods or signals, and the driver checks all mirrors and the doorway before moving. Practice pointing out the zone on a real bus so the distance becomes concrete.
