A cargo tank whose external visual test lapsed last month is loaded with 6,000 gallons of flammable product and sitting at the rack, cleared to roll. Nobody caught it because the test schedule lived in a spreadsheet nobody opened. For a bulk-liquid carrier, that's not a maintenance slip — it's an out-of-spec tank on the highway and a PHMSA finding waiting to happen. Tanker fleet compliance software exists to make that lapse impossible. Book a demo to see HVI track your cargo-tank test cycle
Never let a cargo-tank test lapse put a truck on the road
Periodic test tracking, tank-specific inspections, defect-to-work-order, and PHMSA-ready records — on one connected platform.
The cargo-tank test cycle, tracked by hard expiry date
No other carrier type lives under a test calendar like this. Every DOT-spec cargo tank carries a stack of required periodic tests — each on its own interval, each with a drop-dead expiry, and running a load on a lapsed test is a federal violation. The single biggest thing tanker fleet compliance software does is make sure none of these ever quietly expires.

Internal visual
Leakage test
Leak / vapor-tight (K)
Pressure test
Thickness test
Intervals vary by tank spec and service. HVI calculates each expiry per tank and alerts before the date — not after.
When every test has a live countdown and the system pings you weeks ahead, a lapse stops being a question of whether someone remembered to check the spreadsheet. Start free and load your tank test schedule in minutes
The tanker pre-trip & hazmat checklist HVI loads by default
Beyond the periodic tests, a tanker driver has a daily inspection that a dry-van driver never thinks about: valves, domes, gaskets, hoses, and the hazmat paperwork that has to be right before the truck leaves the rack. This is the checklist HVI ships ready to run, signed on the phone at every pre-trip.
Tank & valves

- Outlets, caps & dust plugs secure
- No product seepage at fittings
Hoses & transfer
- Hoses — cracks, bulges, abrasion
- Couplings & cam-locks secure
- Grounding / bonding cable & reel
- Pump & PTO function (if equipped)
- Vapor-recovery connections
- Spill kit & containment present
- Hose test / cert date current
Hazmat compliance
- Placards correct for product & sides
- Shipping papers / manifest on board
- Emergency response info present
- Tank spec plate legible & valid
- Periodic test dates all current
- Driver hazmat endorsement valid
- Fire extinguisher & PPE on board
Every item signed, every defect photographed, every inspection timestamped. When FMCSA or a facility auditor checks the rig, your tank integrity and hazmat record is already built. Start free — the tanker checklist is loaded on day one
Built for every cargo-tank spec you run
A fuel-hauling DOT-406 doesn't test on the same cycle as a chemical DOT-407 or a corrosive DOT-412, and legacy MC-spec tanks have their own rules. HVI sets the test schedule per tank by its spec and service, so the countdown is always the right one.
Flammable & combustible liquids
Gasoline, diesel, fuel oil. Non-pressure, low-pressure petroleum service.
Chemical & mild-pressure
Flammable & non-flammable chemicals. Round, insulated, pressure-rated.
Corrosive liquids
Acids & corrosives. Smaller diameter, heavier shell, strict integrity rules.
High-pressure / LPG
Propane & compressed gases. High-pressure spec with its own test regime.
Set the spec once and HVI applies the right test intervals and inspection template to that tank — no manual lookup, no wrong cycle on the wrong tank. Book a demo to see spec-based test scheduling
What a lapsed test or missed inspection actually costs
A loaded tanker rolling on an expired periodic test isn't a paperwork problem — it's an out-of-service order, a hazmat violation, and, if product gets out, an incident with environmental and liability exposure that dwarfs any repair bill. The difference between that and a clean record is a tracking system that flags the date before it passes.
Per FMCSA and PHMSA data, hazmat and cargo-tank violations carry some of the steepest penalties in commercial transport, and cargo-tank integrity findings are a recurring audit theme. HVI's test tracking is built to keep every tank ahead of its date. Book a demo to see the expiring-test dashboard
Spreadsheet guesswork vs. automated compliance
One missed date away from trouble
- Test dates in a file nobody opens daily
- No alert before an expiry passes
- Certificates scattered across emails
- Daily tank inspection on paper, if at all
- Audit means a frantic records scramble
- No link between a defect and its repair
Every date, every tank, ahead of time
- Per-tank test countdown with live status
- Alerts weeks before any expiry
- Certificates stored against the tank
- Tank & hazmat eDVIR signed on the phone
- Audit export as a signed PDF in a minute
- Every defect linked to its work order
In a business where one lapsed date can ground a truck or trigger a finding, the record isn't paperwork — it's protection. Start a free trial and build that protection automatically
From a tanker fleet compliance manager
Our whole test schedule lived in one spreadsheet that one person maintained. When she was out for two weeks, we nearly rolled a tank on an expired leakage test — caught it by luck during a yard walk. That was the moment I realized our entire hazmat compliance was resting on somebody's memory and a tab in Excel.
Now every tank has its own countdown and the alerts hit three people before anything is due. We haven't had a lapsed test since, and our last FMCSA review was the smoothest we've ever had because every certificate and inspection pulled up in seconds. In this business, that's the difference between operating and being shut down.

Frequently asked questions
Can HVI track cargo-tank periodic test dates and alert before they expire?
Yes. HVI tracks each required test per tank by its spec and interval, shows a live countdown to every expiry, and alerts your team weeks ahead so no loaded tanker rolls on a lapsed test.
Does HVI support DOT-406, 407, 412, and MC-331 tanks?
Yes. You set each tank's spec and service once, and HVI applies the correct test intervals and inspection template to that tank, so the schedule always matches the equipment.
Does HVI handle hazmat inspection and paperwork checks?
Yes. The default tanker checklist covers valves, hoses, placards, shipping papers, and spec-plate validity, all signed and timestamped at pre-trip for a complete hazmat record.
Can I pull test certificates and inspection records for an audit?
Yes. HVI stores certificates and inspections against each tank and exports them as a signed PDF, so an FMCSA or PHMSA review pulls up in seconds instead of a records scramble.
How quickly can a tanker fleet get running on HVI?
Most carriers run their first signed inspection within a day or two of signup. Loading tank specs, test dates, and driver logins across the fleet typically takes under two weeks.
Run every tank, test, and hazmat check on one record
Periodic test tracking, tank inspections, defect-to-work-order, and PHMSA records — so a lapsed date never grounds a truck or triggers a finding.
