The Driver/Operator, given a fire department pumper and a spotter, shall demonstrate a
diminishing clearance exercise.
II. II. II. II. Instructions Instructions Instructions Instructions –––– Procedures for Achieving the ObjectiveProcedures for Achieving the ObjectiveProcedures for Achieving the ObjectiveProcedures for Achieving the Objective
Given a pumping apparatus and a specified course, the Driver/Operator shall maneuver a
pumping apparatus so that the Driver/Operator accurately perceive the ability of the vehicle to
pass through the openings and so that no obstructions are struck.

This exercise measures a driver’s ability to steer the apparatus in a straight line, to judge
distances from wheel to object, and to stop at a finish line. The pumping apparatus should enter
the course at a minimum speed of 20 mph and must maintain that speed until the front bumper
exits the 8 ft. 2 in. portion of the diminishing clearance lane. This exercise is to be performed
both forward and in reverse with a spotter. There is no minimum speed for performing the
backing portion of this exercise. The
course for this exercise is created by
arranging two rows of markers to
form a lane 75 ft. (22.9 m.) long.
The lane varies in width from 9 ft. 6
in. (2.9 m.) to a diminishing
clearance of 8 ft. 2 in. (2.5 m.). The
driver should maneuver the
apparatus through this lane without
touching the markers. The vehicle
should be stopped at a finish line 50
ft. (15.24 m.) beyond the last
marker. No portion of the vehicle
should protrude beyond this line.
Vertical clearance judgment should
be evaluated using a prop with a crossbar that is adjustable, based on the vehicle height. During
the evaluation, the driver should drive forward and back through the prop with the crossbar at
several differing heights, including one that is lower than the top of the vehicle. The prop should
not be struck. The intent of the vertical clearance judgment is for proper identification of the
furthermost point in the form of the apparatus. In situations where the apparatus is gaining entry
to roadways or limited-height areas, the Driver/Operator must allow appropriate space ahead of
the apparatus in order to avoid striking objects or to avoid extending apparatus into traffic lanes.
