turn on headlights as part of the emergency response.
28
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

30
When driving downhill, which of the following should be done to prevent engine damage?

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
35
Weight carried on most apparatus can contribute to:
skidding or possible rollover due to lateral weight transfer.
36
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.
