49 CFR 396.13
Before driving a motor vehicle, the driver shall:
(a) Be satisfied that the motor vehicle is in safe operating condition;
(b) Review the last driver vehicle inspection report; and
(c) Sign the report, only if defects or deficiencies were noted by the driver who prepared the report, to acknowledge that the driver has reviewed it and that there is a certification that the required repairs have been performed. The signature requirement does not apply to listed defects on a towed unit which is no longer part of the vehicle combination.
