be brought to a complete stop before proceeding.
Before placing apparatus in motion, the driver/operator should ensure any hose carried on apparatus:
will not come loose during travel.
How do drivers establish visual lead time
By scanning the path of travel far enough ahead based on their speed
Which of the following auxiliary brake devices uses a valve to restrict the flow of the exhaust, which creates back pressure that adds to the engine’s inherent braking ability?
Exhaust brake
Which of the following statements about shutting down a hot engine is MOST accurate?
Usually an idling time of three to five minutes is sufficient before shutting down

reaction distance.
On an aerial apparatus, which of the following refers to the angle formed by level ground and a line from the point where front tires touch the ground to the lowest projection at the front of the apparatus?
Angle of approach
What agency in the United States establishes basic requirements for licensing a driver?
Federal Department of Transportation (DOT)
NFPA® 1901, Standard for Automotive Fire Apparatus, requires a placard in every apparatus, listing:
vehicle height and weight in feet and tons
What must driver/operators complete before being allowed to drive under emergency conditions?
A thorough training program
Apparatus equipped with a diesel particulate filter (DPF) will have:
very clean exhaust emissions and no black smoke.
refers to the distance that the vehicle travels from the time brakes are applied until the apparatus comes to a complete stop?
Braking Distance
Which of the following is a guideline when working on, around, or under apparatus?
Always have a second person present.
Driver/operators must perform practical driving exercises:
with each type of apparatus they are expected to drive.
When responding to emergencies, apparatus should:
turn on headlights as part of the emergency response.
In order for apparatus to come to a complete stop on show and ice, it may take
3 to 15 times greater distance than it does on dry pavement
Which of the following transmits data to a radio receiver on a traffic light in order to preempt a signal at the intersection and will operate automatically as long as the apparatus is in range and the transmitter is turned on?
GPS Based Traffic Signal Preemption
When driving downhill, which of the following should be done to prevent engine damage?
Lower downhill speed to lower than maximum rpm
On apparatus equipped with a diesel particulate filter (DPF), which of the following lights up when the exhaust system is very hot, usually due to an active regeneration in process?
High Exhaust System Temperature indicator
Which of the following statements about driver/operator training is MOST accurate?
All fire departments must establish and maintain a thorough training program
Which of the following stability control systems applies brakes independently to aim the vehicle in the direction the operator positions the steering wheel?
Electronic stability control
On an aerial apparatus, which of the following refers to the angle formed by level ground and a line from the point where the rear tires touch the ground to the bottom of the frame at wheelbase midpoint?
Breakover angle
Weight carried on most apparatus can contribute to:
skidding or possible rollover due to lateral weight transfer.
When preparing to start the apparatus, whether for emergency response or a routine trip, the driver/operator must first know the destination and
route of travel.
When giving hand signals for backing apparatus, hand signals should be:
done in a slow, exaggerated motion.
Which of the following is the MOST likely reason for a locked wheel skid?
Braking too hard at high speed
Which of the following statements about warning devices is MOST accurate?
Use of warning devices should be limited to response to true emergencies.
Which of the following statements about the written test for driver/operators is MOST accurate?
The style of questions may vary according to local needs.
On apparatus equipped with a diesel particulate filter (DPF), which of the following lights up to indicate that the DPF is loading up with soot?
DPF indicator
Which of the following is the primary reason for daily pretrip inspections?
Minimize mechanical failure
Driver/operators are subject to any statute, rule, regulation, or ordinance that governs any other vehicle operator:
unless specifically exempt.
When loading fire hose while driving the apparatus, the safety observer to the operation:
must be a member, other than driver/operator and the firefighters loading the hose.
Which of the following is a guideline IFSTA recommends when backing apparatus?
Sound two short blasts of vehicle’s horn immediately before backing apparatus
Which of the following statements about states/provinces and driver/operator regulations is MOST accurate?
States or provinces have latitude to alter federal requirements as necessary.
Which of the following stability control systems becomes active when the antilock braking system computer senses an imminent roll over condition?
Roll stability control
Which of the following generally accounts for a significant percentage of all damage repair costs for a fire department?
Backing accidents
Any equipment not needed while driving to the scene must be
secured in brackets or contained in a storage cabinet.
Which of the following automatically reduces engine torque and applies brakes to wheels that have lost traction and have begun to spin?
Automatic traction control (ATC)
Why should firefighters open the bleeder valve or drain valve between the control valve and cap?
To ensure any trapped pressure is released
Which of the following is recommended by IFSTA when backing apparatus?
Use one or more spotters
Apparatus should be weighed after loading it with all equipment and personnel to ensure that axle loading is balanced:
within 7 percent from side to side.
When more than one emergency vehicle is responding along the same route, they should travel:
at least 300 to 500 feet (90 to 150 m) apart.
