Final answer:
Yes, if the first due truck is a tower ladder, firefighters can ride the bucket to the fire floor.
Step-by-step explanation:
In the case of a tower ladder truck, the firefighters can indeed ride the bucket to the fire floor.
The bucket is attached to a tall ladder that extends to reach higher floors of a building. Firefighters use the bucket to access the fire floor and perform rescue operations or extinguish the fire.
For example, in a situation where the ladder of a tower ladder truck can reach the 10th floor of a building, the firefighters can ride the bucket up to the 10th floor to perform their duties.
