ARB has released a guide detailing how some off-road diesel
vehicles may be retrofit without visibility impairment, and how
to apply for an exemption from the 2010 retrofit requirements if
there is no way to retrofit a vehicle without impairing
visibility. In October, 2009, ARB and Cal/OSHA released a joint
Interim Visibility Policy stating that any vehicle that could not
be retrofit without impairing visibility would be exempt from the
March 1, 2010, retrofit requirements in the off-road diesel
vehicle regulation.

To provide further explanation on retrofit visibility, and
explain what constitutes visibility masking and how some vehicles
may be retrofit without visibility impairment, ARB staff has, in
consultation with Cal/OSHA staff, released a Retrofit Visibility
Guide, available on:
http://www.arb.ca.gov/msprog/ordiesel/vdecssafety.htm.

On that same page, ARB staff has also posted the Exemption
Application for visibility or other safety exemptions.  Finally,
staff has added answers to frequently asked questions regarding
how retrofit visibility issues will affect fleets with existing
retrofits or with retrofits on order.  This page also presents
examples of vehicles that have been retrofit without impairing
visibility, and – once visibility exemptions have been granted –
will host a list of exempt vehicle makes and models.  

As a reminder, any fleet considering whether they need to
perform retrofits should make sure they have reviewed the guide
to new reduced horsepower and reduced activity credits.  This
guide is available on the Knowledge Center at:
