Understanding inspections
DOT annual vs. 90-day BIT.
Most California carriers deal with two programs. Always confirm your exact requirements with FMCSA and the CHP.
Annual DOT Inspection
Federal rules (49 CFR 396.17) require every commercial motor vehicle to pass a periodic inspection at least once every 12 months, with proof kept on the vehicle.
90-Day BIT Inspection
California’s Biennial Inspection of Terminals program requires carriers to inspect trucks and trailers at least every 90 days and keep maintenance records ready for CHP terminal audits.
