* 4.3.2.1 Test course. The total test mileage shall be on roads and highways within the general
geographic limits of the place of manufacture and adjoining states. Any special highway permits
required shall be obtained by the contractor. The course shall be arranged to return the vehicle to
the manufacturer's plant at the completion of each 1,000 miles, if applicable, or at the completion
of the test otherwise, for inspection and chassis servicing.
4.3.2.2 Test loads. Type I level deck and type II drop deck semitrailers shall be tested for
90 percent of the mileage with the semitrailer loaded as specified in table III and for 10 percent
of the mileage with the semitrailer empty. Type V level deck extended semitrailers shall be
tested for 45 percent of the mileage with the rated load evenly distributed, for 45 percent of the
mileage with 65 percent of rated load concentrated as specified in 3.3, and for 10 percent of the
mileage empty. Average speeds during all road tests shall be as close as possible to those
specified in table II.
* 4.3.3 Extended road test. When specified (see 6.2), the first vehicle shall be subjected to an
extended road test as specified in table VII. While negotiating the specified side slopes, in both
directions, the equipment shall be subjected to not less than 10 sine wave turns. While
negotiating the paved road course at highway speed (see table II), the equipment shall be
periodically subjected to at least 25 sudden stops at maximum braking effort and shall be
periodically subjected to at least 25 left and 25 right turn rapid lane change maneuvers that
simulate avoidance of collisions.
