Updated May 8, 2021 Compliance consultant Andy Blair, based in Pennsylvania, sent along a list of out of service violations related to lighting equipment and the hours of service yesterday -- with a mind toward helping haulers of all stripes keep aware particularly of the biggest risks when it comes to violations within the two main focus areas of this week's Roadcheck event, which started today and runs through Thursday, May 6. "I keep up with 49 CFR," or the Code of Federal Regulations, where trucking requirements are found, he said, "and the out-of-service criteria, and still do Level 1 DOT inspections." Blair, of DOT Safety Checkups LLC, is a retired officer, and does these inspections for private industry.
