Which of the following conditions does NOT require low gear when driving an aerial apparatus?

Choosing to use low gear in an aerial apparatus is typically necessary when operating under conditions that demand enhanced control and power, such as navigating challenging terrain or maintaining stability. In this context, traveling around a corner, climbing a hill, and approaching an intersection all require careful management of speed and power, which low gear facilitates.

When accelerating on a straight road, the demand for low gear is less critical because the conditions do not pose the same risks as the other scenarios. On a straight road, the apparatus can maintain stability and speed effectively in a higher gear, allowing for a more efficient acceleration without the need for the torque that low gear provides. This situation generally promotes safer handling of the vehicle, relying on its ability to maintain speed without the extra power modulation that low gear would provide.
