Code, all motor vehicles subject to the program shall undergo a visible smoke test during every smog 

check inspection to determine whether the vehicle emits any visible smoke from its tailpipe or crankcase. 

The conditions and procedures for performing the visible smoke test and recording the results shall be as 

follows: 

(1) The test for visible tailpipe smoke shall be performed immediately following the tailpipe emissions 

phase of the smog check inspection, with the vehicle's engine running at idle. The technician shall return 

the vehicle to idle, exit the vehicle, walk to the tailpipe area of the vehicle and remove the emission 

inspection system exhaust probe from the tailpipe. With an unobstructed view of the vehicle's tailpipe, 

file://D:\$ 3340.42. Mandatory Smog Check Inspection and Test Procedures, and Emission ... 3/26/2010 
California Code of Regulations Page 5 of 9 

the technician shall observe the tailpipe area for at least 10 seconds. If smoke is observed emanating 

from the vehicle's tailpipe, the vehicle fails the visible smoke test and the technician shall enter 

"F" (Defective) in the "Other Emission Related Controls" category of the visual inspection when prompted 

by the emissions inspection system. 

(2) The test for visible smoke emanating from the crankcase shall be performed during the under hood 

portion of the liquid fuel leak inspection specified in subsection (d). The crankcase and PCV systems shall 

not be disconnected during the visible smoke test portion of the liquid fuel leak inspection. With the 

vehicle's engine running at idle, the technician shall observe the crankcase and PCV systems for at least 

10 seconds. If smoke is observed emanating from the vehicle's crankcase or PCV systems, the vehicle 

fails the visible smoke test and the technician shall enter "F" (Defective) in the "Other Emission Related 

Controls" category of the visual inspection when prompted by the emissions inspection system. 

(3) If no smoke is observed emanating from the vehicle's tailpipe, and if no smoke is observed emanating 

from the vehicle's crankcase or PCV systems, the vehicle passes the visible smoke test. The technician 

shall enter "P" (Pass) in the "Other Emission Related Controls" category of the visual inspection when 

prompted by the emissions inspection system. This entry shall be superseded by an entry for any other 

failure that would normally be recorded in the "Other Emission Related Controls" category of the visual 

inspection. 

(4) Smoke that is observed emanating from any area of a vehicle other than the vehicle's tailpipe, or 

crankcase or PCV systems, regardless of the cause, shall not constitute a failure of the visible smoke test. 

(5) If the vehicle fails the visible smoke test pursuant to paragraphs (1) and/or (2), in addition to 

entering the failure into the emission inspection system, the technician shall do all of the following: 

(A) Document the failure by writing or stamping on the vehicle inspection report in the "Other 

Emission Related Components" section, "Failed for visible smoke," or "Failed visible smoke test." 

(B) Document the failure and the operating conditions under which the failure occurred on the invoice 

that is given to the customer pursuant to section 9884.8 of the Business and Professions Code and 

Section 3356 of this chapter. 

(C) Provide to the customer the bureau'svisible Smoke Test Failure Consumer Information Sheet, form 

SMOKE INFO (01/07), as shown in Figure 1, with the applicable items completed on the checklist and 

the vehicle license or identification number. The bureau will furnish stations with a supply of 

information sheets. 

(6) For the purposes of subsection (f), unless the context otherwise requires: 

(A) "Tailpipe" means anywhere the vehicle's exhaust is designed to exit the vehicle under normal 

conditions. There may be more than one location. 

(8) "Unobstructed view" means that there is nothing in the shop environment, such as equipment, 

tools, tool cabinets, tool boxes, furniture, supplies, or the like, which prevents the technician from 

observing the exhaust emanating from the vehicle's tailpipe. 

(g)(l) In the enhanced program areas, heavy-duty vehicles shall be tested using the loaded-mode testing 

method as provided in subsection (a) of this section, unless: 

(A) The vehicle has a drive axle weight that exceeds 5,000 pounds when the vehicle is unloaded, or 

file://D:\$ 3340.42. Mandatory Smog Check Inspection and Test Procedures, and Emission ... 3/26/2010 
California Code of Regulations Page 6 of 9 

(0) The vehicle is classified by the Department of Motor Vehicles as a motorhome, or 

(C) The vehicle has a body and/or chassis configuration or modification made for business purposes 

that renders the vehicle incompatible with loaded-mode testing, or 

(D) The emission inspection system prompts the technician to perform the two-speed idle test. 

(2) For the purposes of this subsection, the term "unloaded" shall mean that the vehicle is not currently 

transporting loads for delivery or is not carrying items of a temporary nature, but excludes items that 

have been welded, bolted or otherwise permanently affixed to the vehicle, and tools, supplies, parts, 

hardware, equipment or devices of a similar nature that are routinely carried in or on the vehicle in the 

performance of the work for which the vehicle is primarily used. 

(3) For the purposes of this subsection, modifications that render a vehicle incompatible with loadedmode testing shall not include any tire, wheel, body or chassis modifications made for other than business 

purposes. 

(4) If it is determined that a heavy-duty vehicle cannot be subjected to a loaded-mode test for any of the 

reasons set forth in subparagraphs (A) through (D) of paragraph (1) of this subsection, the technician 

shall perform a two-speed idle test. The technician shall also note on the final invoice the justification for 

the performance of a two-speed idle test. 

(h) Pursuant to section 39032.5 of the Health and Safety Code, gross polluter standards are as follows: 

(1) A gross polluter means a vehicle with excess hydrocarbon, carbon monoxide, or oxides of nitrogen 

emissions pursuant to the gross polluter emissions standards included in TABLES I, I1 or 111. 

(2) Vehicles with emission levels exceeding the emission standards for gross polluters during an initial 

inspection will be considered gross polluters and the provisions pertaining to gross polluting vehicles will 

apply, including, but not limited to, sections 44014.5, 44015, 44017 and 44081 of the Health and Safety 

Code. 

(3) A gross polluting vehicle shall not be passed or issued a certificate of compliance unt~l the vehicle's 

emissions are reduced to or below the applicable emissions standards for the vehicle as indicated in 

TABLES I, 11, or 111. However, the provisions described in section 44017 of the Health and Safety Code 

may apply.
