is a Smog Check?
smog check is atest done on a exhaust
system of a motor vehicle to determine
how many pollutants, and of which
type, the vehicle is emitting. All
states have emissions limits which
vehicles cannot exceed. During a smog
check, a device is connected to the
tailpipe while the engine is run to
determine the emissions of the car
in idle and while being revved, which
are measured against the state standard
for that type of vehicle. The smog
technician also checks to make sure
that the muffler is in working order,
and usually opens the hood to make
sure that all hoses and pipes are
properly connected, and that the car's
internal computer is working properly.
states have a biannual smog check
program, while others require testing
every year. Most states exempt certain
vehicles from the smog check, such
as vehicles more than thirty or less
than five years old. Most states require
a successful smog check to sell a
vehicle, and will require a smog certificate
before the title can be transferred.
Consumers should check with their
state's Department of Motor Vehicles
to find out more about the smog requirements
for their area.
