Regulation Navigator
Start with the trucking task at hand, read an explanation and find the regulation and official sources.
What are you working on?
Start with a work situation to understand the requirements, common mistakes and next steps.
Roadside inspections, warnings and crash records
Inspection reports, out-of-service orders and accident reports are different matters. Secure the scene first, then handle handoff, repairs and deadlines separately.
California CA numbers and MCP permits
An MCP is California’s carrier operating permit; registration plates or a federal number cannot replace it. Determine applicability, then check permit, insurance and renewal status.
IRP registration and distance records
IRP distance reporting must trace back to each vehicle’s actual trips, including empty, intrastate and repositioning movements. A California-to-neighboring-state trip illustrates what the driver keeps and how the office summarizes it.
IFTA, fuel permits and tax records
Where fuel is purchased and where the vehicle uses it are separate records to preserve. A quarter without interstate trips illustrates why an existing IFTA account still needs filing and record checks.
California idling and cab power
When parking a heavy diesel truck in California, distinguish the propulsion engine from other power equipment before checking restrictions. A waiting-at-a-stop example shows why “five minutes” is not the whole rule or a substitute for its conditions.
Transport refrigeration unit emissions requirements
Refrigerated transport requires checks beyond the tractor: the diesel refrigeration unit has its own emissions program. A last-minute trailer swap illustrates which official program records to check before accepting the equipment.
TWIC and secure-area access
TWIC is a personnel-security credential, not a substitute for port requirements on vehicles, carriers or the job itself. A first container pickup illustrates enrollment, card validity and facility-access checks.
Hazmat basics and shipment checks
Before accepting hazardous material, check training, shipping papers, placards and emergency information. A UN number or an SDS alone does not establish transport compliance.
