what are the 3 things a driver of a DOT does before driving?
1) be satisfied that the motor vehicle is in safe operating condition
2) review the last vehicle inspection report
3) sign the report, only if defects or deficencies were noted by the driver who prepared the report, to acknowledge that the driver has reviewed it and that there is certification that the required repaird have been performed. the signature requirement does not apply to the listed defects on a towed unit which is no longer part of the vehicle combination.
