STUDENTS (2026–2027 EDITION) A+ GRADED
1. According to NFPA 1002, a fire apparatus driver/operator must be able to
perform a routine test on the apparatus braking system to ensure the
vehicle can stop within a specified distance at a speed of:
a) 10 mph
b) 20 mph
c) 30 mph
d) 40 mph
b) 20 mph
Rationale: NFPA 1911 requires a service break test from 20 mph on a dry,
level surface to verify stopping distance is within acceptable limits for the
vehicle's weight.
2. The primary purpose of conducting a daily pre-trip inspection is to:
a) Satisfy insurance requirements only
b) Ensure the apparatus is mechanically sound, all equipment is present,
and it is safe to operate
c) Test the pump under load
d) Fill the fuel tank
b) Ensure the apparatus is mechanically sound, all equipment is present,
and it is safe to operate
Rationale: The pre-trip inspection is a systematic check that identifies
, defects before the vehicle responds, reducing the risk of breakdown or
accident.
3. Which of the following fluid levels is NOT typically checked during a routine
apparatus inspection?
a) Engine oil
b) Transmission fluid
c) Power steering fluid
d) Pump gear case oil level
d) Pump gear case oil level
Rationale: Pump gear case oil is a sealed system that does not require daily
checking unless a leak is suspected; engine oil, transmission fluid, and
power steering fluid are routine daily checks.
4. The "cab tilt" procedure on a tilt-cab apparatus must be performed:
a) While the engine is running at idle
b) According to manufacturer's instructions, with the cab clear of personnel
and loose items
c) Only by a certified mechanic
d) With the transmission in gear
b) According to manufacturer's instructions, with the cab clear of
personnel and loose items
Rationale: Tilting the cab is a maintenance function that requires following
specific safety steps to prevent injury or damage.
5. When driving a fire apparatus under non-emergency conditions, the
driver/operator must obey all traffic laws and operate with:
a) Due regard for the safety of others
b) The right-of-way at all times
c) Lights and sirens activated
d) No regard for speed limits
a) Due regard for the safety of others
Rationale: "Due regard" means the driver operates in a manner that does
, not endanger life or property, even when responding to an emergency with
lights and siren.
6. The maximum speed at which an apparatus may safely negotiate a curve
depends on:
a) The siren's volume
b) The vehicle's center of gravity, weight, and road conditions
c) The number of firefighters on board
d) The time of day
b) The vehicle's center of gravity, weight, and road conditions
Rationale: Speed must be adjusted to prevent rollover or loss of control,
particularly with the high center of gravity and heavy loads typical of fire
apparatus.
7. When backing an apparatus, the preferred method is to:
a) Use mirrors only
b) Use a spotter positioned at the rear, maintaining visual or audible contact
c) Back quickly to clear the area
d) Sound the horn continuously
b) Use a spotter positioned at the rear, maintaining visual or audible
contact
Rationale: A spotter helps overcome blind spots; if visual contact is lost, the
driver must stop immediately.
8. The "overhang" of a fire apparatus is the distance from:
a) The front axle to the front bumper
b) The rear axle to the rear bumper
c) The front bumper to the rear bumper
d) The top of the cab to the ground
b) The rear axle to the rear bumper
Rationale: Rear overhang affects turning radius; the rear of the vehicle
swings wide and can strike obstacles.
9. A centrifugal fire pump is classified as a:
a) Positive displacement pump
, b) Non-positive displacement pump that uses an impeller to create
centrifugal force
c) Piston pump
d) Rotary vane pump
b) Non-positive displacement pump that uses an impeller to create
centrifugal force
Rationale: Centrifugal pumps depend on velocity and impeller rotation; they
are the standard on modern fire apparatus because they can deliver
variable flow and pressure.
10.The device that removes air from the pump and hard suction hose during
drafting is the:
a) Transfer valve
b) Relief valve
c) Primer
d) Discharge gate
c) Primer
Rationale: The primer creates a vacuum in the pump body and intake,
allowing atmospheric pressure to push water up the suction hose.
11.When operating a centrifugal fire pump, cavitation can occur if:
a) The pump is in parallel mode
b) The incoming water supply is insufficient, causing a vacuum that forms
water vapor bubbles
c) The discharge pressure is too low
d) The engine RPM is too low
b) The incoming water supply is insufficient, causing a vacuum that forms
water vapor bubbles
Rationale: Cavitation results when the pump tries to lift water beyond its
capability or the supply is restricted; bubbles collapse violently, damaging
the impeller and reducing flow.
12.The master intake gauge on a fire pump reads:
a) Discharge pressure only
