Which driving exercise tests the driver/operator's ability to maneuver the apparatus around obstacles?

The serpentine driving exercise specifically tests a driver/operator's ability to maneuver the fire apparatus around obstacles effectively. This exercise involves navigating a designated course that may include cones or other markers arranged in a zig-zag pattern. This challenges the driver to skillfully control the vehicle's speed and direction, mimicking situations where they must navigate tight spaces or avoid obstacles while responding to emergencies.

In contrast, the emergency braking exercise focuses on the driver's ability to bring the vehicle to a stop quickly and safely, while the controlled stop exercise evaluates how well a driver can slow down and stop the apparatus under specific conditions. The road course driving option typically assesses general driving skills and may not emphasize maneuverability around obstacles in the same way the serpentine exercise does. Therefore, the serpentine driving exercise is the most relevant for testing maneuverability around obstacles, making it the correct choice.
