Form details

Vehicle and driver

Identify the unit before you walk it. This header is a walkaround ID block, not a 49 CFR 396.11 post-trip DVIR.

18 fields
Vehicle and driver

Inspection station

In cab and engine start

CDL 11M treats a failed air or hydraulic brake demonstration as an automatic failure of the vehicle inspection test. Use the OEM psi values for the unit in front of you.

25 items
In cab and engine start

Safe entry / parking brake

Set parking brake(s), transmission in neutral or park, chock wheels before an air test. Face the vehicle and keep 3 points of contact when entering or exiting.

If equipped, DEF or DPF lamp behaves as the manufacturer specifies at start (no unexplained warning).

DEF / DPF indicator: OK, Defect, or N/A

Gauges

Oil pressure, coolant temperature, voltmeter or ammeter, tachometer, and speedometer show normal readings after start, per the OEM.

Governor cutoff (air)

With wheels chocked, build air to compressor governor cutoff. The CDL vehicle inspection test describes a typical cutoff near 120 to 140 psi. Record the cutoff your OEM specifies. This is a skills-test / manufacturer value, not a 49 CFR numeric limit.

Governor cutoff (air): OK, Defect, or N/A

Air leakage rate (CDL test)

Engine off, key on, parking brake released (and tractor protection released on a combo), foot brake held 1 minute after the gauge stabilizes. CDL 11M: drop of more than 3 psi in 1 minute (single vehicle) or 4 psi in 1 minute (combination) fails the test. Use the OEM procedure if it differs.

Air leakage rate (CDL test): OK, Defect, or N/A

Low air warning

Fan brakes down. Audible or visible warning must operate continuously at 55 psi (379 kPa) and below, or at one-half of compressor governor cutout, whichever is less (49 CFR 393.51(c)). Know the OEM spec if it is higher.
