CALIFORNIA EMISSIONS TEST CENTERS AND TESTING INFORMATION
emissions standards are set by the California Air
Resources Board. CARB sets
requirements which limit the amount of pollutants that are allowed to be released into the atmosphere. The emissions standards focus on pollutants produced by automobiles and other gasoline powered emission producing vehicles.
CARB also regulates emissions
from power plants, small equipment such as
lawn mowers, and industrial businesses.
The California Air Resources
Board generally regulates the emissions of NOx, Sulfur Oxides,
Particulate Matter such as soot, Carbon Monoxide (CO), and
Hydrocarbons. These three harmful pollutants cause the
formation of smog.
What are Emission Test Standards and How are Emissions
Measured during the Emissions Test?
The California Air Resources
Board and the Bureau of Automotive Repairs have evaluated
and researched vehicle emission pollutions for the
past 25 years and determined emission test
standards used which promote clean air and deter
vehicle owners from driving harmful emissions producing
cars, trucks, vans, SUVs and motorhomes on California
highways and roadways. Emissions test standards
are limits that set thresholds for vehicle exhaust
emissions. Emission performance standards have been used
to limit emission pollutants such as oxides of
nitrogen, Carbon Monoxides and Hydrocarbons via emissions
test metering devices also known as "smog machine"/s.
California utilizes private
industry in the form of emission test centers commonly known
as smog stations to test and evaluate California
vehicle emissions. Used California vehicles 6 years and older are required
to undergo an emissions test during their
initial California registration, once every two years thereafter, and during a title transfer.
The emissions test will sample the vehicle's exhaust emissions and
measure them against a digital Emissions Cut Score Chart established
by the Air Resource Board. Based on the vehicle's year, weight and engine
size the smog machine will determine whether the vehicle passed or
failed the emissions test.
The state of
California has more stringent vehicle emissions standards
then other states due to the fact it has one of the largest automotive
markets in the world. The California Air Resource Board has
great influence over the emissions requirements that automakers must meet
if they wish to sell their new vehicles in California. CARB lists
16 other states which will be adopting CARB rules and emissions
test standards by mid 2009.
Federal emission II level standards
have begun phasing in since 2004, and are planned on continuing
until 2009. Automobiles and light trucks including SUVs, pickup trucks, and
minivans will be treated differently under certain standards based on
vehicle weight and engine size.
