These guides answer the questions drivers and dispatchers ask most: what to do in the first ten minutes after a breakdown, which defects will get a truck placed out of service at a roadside inspection, whether a DPF regen can be done on the shoulder, how to track down an air leak, and how South Texas heat wears out tires, batteries, and cooling systems.
Each one is written with Laredo in mind — bridge-line idling, drayage yards on Mines Road, the I-35 checkpoint, and long two-lane runs on US-59, US-83, and SH-359.
They’re general information, not a substitute for your carrier’s procedures or the current FMCSA and CVSA rules. When a truck needs hands-on help, see our mobile repair services or call dispatch any time at (956) 955-6077.
