The cruise mode test shall be performed first on a chassis dynamometer at the speeds and loads shown in the following table:
Loading Class | Number of Cylinders | Vehicle Shipping Weight | Speed (mph) | Loading (Hp) |
1 | 4 or less | -- | 4 ± 1 | 10 ± 1 |
2 | 5 or 6 | -- | 40 ± 1 | 15 ± 1.5 |
3 | 7 or more | less than 3,250 lbs. | 40 ± 1 | 17.5 ± 1.5 |
4 | 7 or more | 3,250 lbs. or more | 40 ± 1 | 20 ± 1.5 |
A vehicle which cannot reach the speed and load specified in the table above, or which by its original design cannot be tested at cruise on an inspection center dynamometer, may be exempted from the cruise mode of the test. Vehicles owned by licensed fleet operators may be exempted from cruise mode test, provided an underhood functional inspection is performed on these vehicles, in addition to idle mode test. An idle mode test may be performed on vehicles at one lane inspection centers wherever dynamometers are inoperative.
The idle mode test shall be performed with the transmission set in neutral gear with the engine at its normal operating temperature. The cruise mode test shall be performed with automatic transmission in drive and with manual transmission set in high gear but overdrive will be disengaged.
