Fire Apparatus Driver Operator (Tiller) Questions
with correct answers
The first elevated streams were water towers mounted on wagons and
pulled by horses. When raised, these elevated streams could raise
___________ in the air. Correct Answer-30ft

The first _____________ fire apparatus to discharge water was a unit
called a _________. This small truck carried a large _____________ and
50 ft (15 m) or more of small hose (booster line size). It also carried a
supply of double-jacked cotton hose, a short ladder, and a running board
on which the fire fighters would ride. Small fires were extinguished with
the soda acid device, while larger fires used the hose connected directly
to the hydrant. Correct Answer-gasoline powered engine
chemical wagon
soda acid extinguisher

Later additional aerial devices were developed that included articulated
booms and ladder towers. The ________________provided greater
flexibility in operating in areas filled with electrical wires and other
obstructions. The ________________ provided a solid platform at the
end of a boom. It gave fire fighters a platform to work from, a device to
use for rescue that eliminated the need for the victims to navigate down
a ladder, and a platform to provide water tower equipment. Correct
Answer-articulated boom
ladder tower

,_____________, also known as compression brakes, open valves in the
cylinders of diesel engines to divert compression from the cylinders to
create drag that slows the vehicle. Correct Answer-Engine Brakes

_____________________divert transmission fluid through a retarder
chamber, which causes resistance to be applied to the driveline with the
energy dissipated through heat transfer to the vehicle's cooling system.
Correct Answer-Transmission retarders

___________________restrict exhaust flow from the engine; the
compression held in the engine limits the movement of the piston and, in
turn, the crankshaft, thereby slowing the vehicle. The excess
compression is forced through the exhaust brake, which absorbs the
energy. Correct Answer-Exhaust retarders

_________________essentially use an electrical current to create a
magnetic force that slows the rotation of a driveshaft or axle. Correct
Answer-Driveline retarders

______________uses sensors mounted on each wheel to control brake
application in the event of a sudden or emergency stop. The brake
application applies the correct amount of brake to each wheel to prevent
the wheels from locking up and placing the vehicle in a skid. Correct
Answer-Anti-lock braking systems (ABS).

_______________________operates in conjunction with the vehicle's
ABS system using the same wheel speed sensors and brake application
devices. The __________ detects situations in which the vehicle may

,enter into a skid and applies precise amounts of braking to help the
vehicle maintain traction in slippery road conditions, thereby allowing
the driver/ operator to maintain steering control of the vehicle. Correct
Answer-Automatic traction control (ATC)

Most fire apparatus manufacturers utilize crash testing to ensure the
crashworthiness of their designs. It should be noted that while
commercial and custom cabs are both subjected to rollover crash testing,
only _______________ are subjected to frontal impact testing. Correct
Answer-custom cabs

Many custom fire apparatus manufacturers offer cabs outfitted with
supplemental restraint systems for some or all riding positions, including
front air bags, side air bags, and curtains. This equipment is usually
combined with seat belt pretension devices and suspension seat pull-
down devices. Such protective devices can reduce injury during a
rollover as long as the occupants are seated and belted. Correct Answer-
Supplemental restraint systems

vehicle data recorders record information such as
___________________. VDR data is controlled data, and the driver/
operator and crew do not typically have access. (TQ '16) Correct
Answer-vehicle speed
acceleration and deceleration data
engine speed
throttle position
braking system status
seats occupied and seatbelt status

, the use of audible and visual warning devices
time and date

These systems are designed to assist the driver/ operator with the safe
operation of the apparatus by maintaining the straight orientation of the
vehicle in an effort to prevent rollover collisions. Steering wheel
positioning sensors, lateral positioning sensors, and accelerometers work
in conjunction with the ABS system to determine when the vehicle is
approaching a rollover threshold and then take action by depowering the
engine and apply the appropriate amount of braking. Correct Answer-
Electronic stability control (ESC).

Both mechanical and electronic devices are available to measure the
lateral acceleration of a vehicle . Although these devices will not prevent
a rollover, they can be used effectively as a driver training tool to
indicate when the vehicle is approaching the rollover threshold and as a
reminder to the driver that excessive lateral acceleration can lead to a
rollover event. Correct Answer-Lateral acceleration alert device

________________ requires warning light systems to include two
modes: (1) a mode that makes the apparatus visible to other drivers in
order for them to yield the right-of-way to the responding apparatus, and
(2) a mode for use on the emergency scene that makes the apparatus
visible while on scene, especially while blocking at roadway incidents.
The blocking mode shuts off all forward-facing white lights and may
shed additional warning lights on the sides and rear of the apparatus
once the vehicle's parking brake is set. Correct Answer-NFPA 1901
