obstructions from vehicle or engine parts (including all manufacturer available optional 

equipment) except for flexible parts (e.g., vacuum hoses, ignition wires) that can be 

moved out of the way without disconnection. Alternatively, information required by 

these specifications to be printed on the label shall be no smaller than 8 point type size 

(2 millimeters in height) provided that no vehicle or engine parts (including all 

manufacturer available optional equipment), except for flexible parts, obstruct the label.

(8) The labels and any adhesives used shall be designed to withstand, for the 

off-highway recreational vehicle’s total expected life, typical off-highway recreational 

vehicle environmental conditions at the location where a label has been attached. 

Typical off-highway recreational vehicle environmental conditions include, but are not 

limited to, exposure to engine fuels, lubricants and coolants (e.g., gasoline, motor oil, 

brake fluids, ethylene glycol), engine operating temperatures, steam cleaning, and 

paints or paint solvents. The manufacturer must submit, with its certification application, 

a statement attesting that its labels comply with this requirement.
I-18

(9) The manufacturer must obtain approval from the Executive Officer for all 

emission control label formats and locations prior to certification. Approval of the 

specific tune-up specifications and adjustments is not required; however, the format for 

all such specifications and adjustments, if any, is subject to review. If the Executive 

Officer finds that the information on the label is vague or subject to misinterpretation, or 

that the location does not comply with these specifications, the Executive Officer may 

require that the label or its location be modified accordingly.

(10) Samples of all actual production emission control labels used within an engine 

family shall be submitted to the Executive Officer of the state Air Resources Board 

within thirty days after the start of production.

(11) The Executive Officer may approve alternate label locations or may, upon 

request and when the Executive Officer determines warranted, waive or modify one or 

more of the label content requirements, provided that the intent of this section is 

satisfied.

(12) If the Executive Officer finds any off-road motorcycle, all-terrain 

vehicle,off-highway recreational vehicle or engine manufacturer using emission control 

labels that are different from those approved or that do not substantially comply with the 

readability or durability requirements set forth in this section, the Executive Officer may 

invoke section 2109, title 13, California Code of Regulations.
