Double bottom tankers need to be
modified in two places in order to
become stable enough to be returned to
the road in Michigan, states a report by
the University's Highway Safety
Research Institute (HSRI).
The report, delivered to the Office of
Highway Safety and Planning Monday,
recommends that the tandem tankers
be kept off the road until they have un-
dergone the necessary modifications
because they have "exceptionally low"
stability. In January, Governor
Milliken issued an emergency order
which banned those trucks from Detroit
and other municipalities except late at

tanker's tipping over to a level "com-
parable" to single tankers currently in
use in Michigan, according to the
report. The two modifications are ex-
pected to cost $3,000 per truck.
"We look upon them (the
modifications) as serving to upgrade

The AMC defect involves an
inadequately brazed joint in the
exhaust gas recirculation system,
which frequently breaks and makes the
system ineffective.
Ford Motor Co. was recently ordered
to recall 640,000vehicles for similar
problems and EPA said the defective
part in both the Ford and AMC exhaust
systems was manufactured by the
Eaton Corp.
AMC's recall announcement said the
company would make the repairs free
of charge if affected cars were brought
to dealers.

This double-bottom tanker, equipped with the modifications recommended by the University Highway Safety Research
Institute, passed the obstacle course test this April with honors while tankers without the modifications did not. The extremi-
ties on either side are training wheels which keep the tanker from falling over during its trial run.
