Correct: Incorrect fluid level is not a suspension defect — suspension defects include missing u-bolts, broken leaves, and loose frame members, all of which are structural issues.

Correct: When backing a straight truck or bus, turn the top of the steering wheel toward the direction you want to go — this is the same intuitive direction as backing a car.

Correct: Signaling early before a turn is the most important communication action — it gives following drivers the most time to adjust and prevents them from attempting to pass.

Correct: When roads are slippery, turn off the retarder — it applies extra braking force to drive wheels that may already have poor traction, which can cause a skid.

Correct: A skid happens when tires lose their grip on the road due to over-braking, over-accelerating, driving too fast for conditions, or turning more sharply than traction allows.

Correct: Three red reflective triangles are required emergency equipment on every commercial vehicle — they must be available for immediate use whenever the vehicle stops on a road.

Correct: The one thing ABS does prevent is wheel lockup during hard braking — it does not compensate for unsafe driving behaviors or reduce the need for safe following distances.

Correct: The correct order is vehicle inspection, then basic vehicle control, then on-the-road driving — each stage builds on the one before it.

Correct: The on-the-road skills test measures your ability to control the vehicle in real traffic conditions — overall vehicle control is the core competency being evaluated.

Correct: Position your helper near the back of the vehicle where you can see them in your mirrors — if you lose sight of them, stop immediately until contact is re-established.

Correct: Doubling your speed gives your vehicle four times the destructive power and requires about four times the distance to stop.

Correct: When two left-turn lanes are available, always take the right lane — starting in the inside lane may force you into other lanes to complete the turn.

Correct: Seeing hazards lets you be prepared by giving you more time to act before a situation becomes an emergency.

Correct: To prevent rollback when starting on a hill with a manual transmission, partly engage the clutch as you release the parking brake — this holds the vehicle while you accelerate.

Correct: To obtain a CDL you must complete Entry Level Driver Training and pass both knowledge tests and skills tests — both components are required.

Correct: ABS malfunction does not disable your regular brakes — continue driving normally using standard braking technique and have the ABS system serviced as soon as possible.

Correct: Slow to a safe speed before entering the curve, then accelerate slightly as you come through — this maintains traction and keeps the vehicle stable.

Correct: All of the listed signs — clear reflections, raindrops on the surface, and tire splashes — can indicate standing water and potential hydroplaning conditions.

Correct: All three skills — accelerating, steering, and stopping — are required for safe commercial vehicle operation, and proficiency in each one is necessary.

Correct: Oil pressure should reach normal range within seconds of starting the engine — a slow or absent pressure rise is a warning sign that requires immediate attention.
