Current through Register Vol. 48, No. 9, September 27, 2024
The purpose of 38-382 is to identify critical vehicle
inspection items and provide criteria for placing vehicle(s) out-of-service
subsequent to a safety inspection.
Except where state, provincial, or federal laws preclude
enforcement of a named item, motor carrier safety enforcement personnel and
their jurisdictions shall comply with these vehicle Out-of-Service violation
standards.
NOTE: Decal Qualification: Each vehicle (truck, truck
tractor, semitrailer, trailer, etc.) must "pass" inspection to qualify for a
decal. "Pass Inspection" means that no violations/defects are found of the
vehicle inspection items contained in the definitions of Level I and Level V
inspections. For the purpose of decal issuance, if no violation is detected
during a Level I or Level V inspection due to a hidden part, which includes the
vehicle inspection items listed in the definitions, a decal shall be
applied.
The decal criteria apply only to the condition of the
vehicle, not the driver. It is possible for a driver to be Out-of-Service and
still have vehicle(s) qualify for a decal. If each vehicle, whether used singly
or in a combination, passes inspection, a current CVSA decal shall be affixed
and no other CVSA decals shall be visible.
OUT-OF-SERVICE: Authorized personnel shall declare and mark
"out of service" any motor vehicle which by reason of its mechanical condition
or loading would likely cause an accident or breakdown. An "Out of Service
Vehicle" sticker shall be used to mark vehicles "out of service". No motor
carrier shall require nor shall any person operate any commercial motor vehicle
declared and marked "out of service" until all repairs by the "out of service
notice" have been satisfactorily completed.
No person shall remove the "Out of Service Vehicle" sticker
from any motor vehicle prior to completion of all repairs required by the "out
of service notice".
Violations other than out of service conditions detected
during the inspection process will not preclude the completion of the current
trip or dispatch. However, such violations must be corrected or repaired prior
to re-dispatch.
These criteria are neither suited nor intended to serve as
vehicle maintenance or performance standards.
1. Brake System.
a. Defective Brakes.
The number of defective brakes is equal to or greater than
20 percent of brakes on the vehicle or combination. A defective brake includes
any brake that meets one of the following criteria: (NOTE: Steering axle brakes
under 1.b are to be included in 20 percent criterion.)
(1) Absence of effective braking action upon
application of the service brakes (such as brake linings failing to move or
contact braking surface upon application). (38-393.48(a))
(2) Missing or broken mechanical components
including: shoes, linings, pads, springs, anchor pins, spiders, cam rollers,
push-rods, and air chamber mounting bolts. (38-393.48(a))
(3) Loose brake components including air
chambers, spiders, and cam shaft support brackets. (38-393.48(a))
(4) Audible air leak at brake chamber,
(Example - ruptured diaphragm, loose chamber clamp, etc.) NOTE: Also check
under 1.h. -Air Loss Rate. (38-396.3(a)(1))
(5) Brake adjustment limits. Bring reservoir
pressure between 90 to 100 psi, turn engine off and then fully apply the
brakes.
(a) One brake at 1/4 inch or more
beyond the readjustment limit. (Example: Type 30 clamp type brake chamber
pushrod measured at 2-1/4 inches would be one defective brake.)
(38-396.3(a)(1))
(b) Two brakes
less than 1/4 inch beyond the readjustment limit also equal one defective
brake. (Examples: Clamp type 30 pushrods measure - Two at 2-1/8 inches. This
example would equal one defective brake. (38-396.3(a)(1))
(c) Any wedge brake where the combined brake
lining movement of both top and bottom shoes exceeds 1/8 inch. (38-396.3(a)(1))
Brake Adjustment. Shall not meet or exceed those
specifications contained hereunder relating to "Maximum stroke at which Brakes
Must Be Readjusted." (Dimensions are in inches.)
