When does a motor carrier require a written Hazmat Security Plan under 49 CFR Part 172 Subpart I?

A written Hazmat Security Plan is mandatory when transporting Highway Route Controlled Quantities (HRCQ) of radioactive materials, more than 55 lbs of Division 1.1, 1.2, or 1.3 explosives, Poison/Toxic-by-Inhalation (TIH/PIH Zone A/B) in bulk containers, or bulk shipments requiring placarding of more than 3,500 gallons or 468 cubic feet.

How does Exspeedite TMS enforce mandatory NRHM routing and 2-hour driver check-ins?

Exspeedite locks in FMCSA-designated Non-Radioactive Hazardous Materials (NRHM) preferred highway networks, restricts drivers from unapproved urban centers or tunnels, and automatically verifies satellite telemetry or driver check-in pulses every 2 hours as required under 49 CFR § 397.67.

Hazmat Security Plan & FMCSA High-Hazard Route Verification

Operational compliance manual for hazmat carriers: enforce 49 CFR Part 172 Subpart I security protocols, generate FMCSA § 397.67 written route plans, automate 2-hour geofence security check-ins, and integrate ERG 2024 first-responder documentation.

FMCSA Preferred NRHM Routes

49 CFR Part 397 mandates the use of state-designated Non-Radioactive Hazardous Materials routes. Exspeedite prevents dispatch over restricted tunnels, residential arteries, and prohibited city bypasses.

Automated 2-Hour Check-In Pulse

For high-hazard security loads (TIH Zone A, Explosives 1.1/1.2), dispatchers and safety directors receive real-time ELD telemetry alerts if vehicle position is not verified within mandatory 2-hour rolling windows.

Immutable Written Route Plans

Generate federal pre-trip written route plans (§ 397.67) directly on the driver's mobile device, including designated safe havens, emergency phone numbers, and state police dispatch contacts.
