Will it pass a DOT inspection?
Snap a photo of the rig — or just describe the issue. Either way, Rig Pig checks it against DOT out-of-service criteria.
🪝 Just hooked a trailer somebody else dropped?
The moment you pull it, its defects become your inspection record. The Drop-and-Hook 5 is the two-minute photo walk that keeps you from inheriting somebody else's out-of-service. Check each one off as you shoot it — the analyzer above and the evidence pack below work on these same photos.
Photograph anything questionable before you move and save it as a dated record in the evidence pack below. A timestamped photo taken at the hook is the difference between "their defect" and "your violation."
📏 Measure it — some calls aren't discretion, they're a number
Most of a roadside inspection is the officer's judgment. A short list of defects isn't: CVSA's out-of-service criteria put a hard number on them, and the officer will measure. If your photo shows one of these, run the same measurement yourself before you roll. (From CVSA's North American Standard Out-of-Service Criteria and 49 CFR; CVSA revises the criteria every April — check the current edition.)
- Strap webbing cuts. Add up every cut, burn, and hole through the webbing along the strap's working length. Over 3/4 in. total on a 4-in. strap, over 5/8 in. on a 3-in. strap, or over 3/8 in. on a 2-in. or 1-3/4-in. strap — the tiedown is defective, no judgment involved. Same verdict for more than 25% of the stitch pattern separated, and for any knot, splice, or repair. (CVSA Tiedown Defect Table.)
- Brake hose chafing. A hose resting on a component isn't a violation by itself. The line is the outer reinforcement ply: chafe damage that reaches or goes through it is a violation and out-of-service territory. Worn cover alone, no ply showing — that's the discretion zone.
- The 20% brake rule. If 20% or more of the service brakes on the vehicle or combination are defective, the whole rig is out of service. Since April 2026, a disconnected service gladhand counts toward that 20% instead of being an automatic out-of-service by itself.
- Rims. Missing rim material over 3 in. in the bead area is out of service — added to the criteria in April 2026, matching the long-standing 3-inch crack rule.
- Rotor rust (air disc brakes). Severe rust over the rotor's friction surface counts as a defective brake — rust is the visible tell that the brake isn't doing its share of the work, and it feeds the 20% count above.
- Air suspension. A deflated air bag is out of service even if the truck still sits level, and suspension or axle-positioning parts that are cracked, broken, loose, or missing are violations under 49 CFR 393.207 — hardware included, not just the bag itself.
- Missing WLL tag. In the U.S., an unmarked strap loses its printed rating and gets the lower default working load limit instead (49 CFR 393.108 — 1,000 lb per inch of strap width). In Canada, an unmarked tiedown isn't legal at all and counts as zero. Either way: if you can't read the tag, don't count the strap at full rating.
Everything not on this list is still officer's discretion — the measured list stays short on purpose. When a number exists, the tape measure settles what a photo can't.
📐 Brake stroke — the test the camera can't do
Brake problems are the #1 out-of-service category there is (39.1% of vehicle out-of-service orders at CVSA's 2026 Roadcheck), and the deciding measurement — pushrod stroke — is invisible in a photo. So Rig Pig doesn't pretend to see it. Do the two-minute manual test the officer does:
- Build air to 90–100 psi, engine off, parking brakes released.
- Chalk the pushrod right at the brake chamber face, brakes released.
- Fully apply the service brakes (a helper on the pedal, or a pedal prop) and measure from your chalk mark to the chamber face with a tape. That distance is the applied stroke.
- Compare it to the limit for that chamber size — stamped on the chamber or in the table below.
Readjustment limits — clamp-type chambers (49 CFR 393.47(e)):
| Chamber type | Standard stroke limit | Long-stroke limit |
|---|---|---|
| 16 | 1-3/4 in. | 2 in. |
| 20 | 1-3/4 in. | 2 in. (2-1/2 in. if marked 3-in. rated stroke) |
| 24 | 1-3/4 in. | 2 in. (2-1/2 in. if marked 3-in. rated stroke) |
| 30 | 2 in. | 2-1/2 in. |
| 36 | 2-1/2 in. | — |
How to read it: past the table limit, the brake is out of adjustment (49 CFR 393.47). At 1/4 in. or more past the limit, CVSA counts it as a defective brake toward the 20% rule above. And if an automatic slack adjuster keeps going out of stroke, the adjuster is the messenger, not the disease — something upstream is worn. Repeatedly hand-adjusting it just hides that. Flag it for the shop and write it on the DVIR.
📁 Evidence pack — built for DataQs
Why keep your own records?
DataQs is FMCSA's system for asking for a review of inspection and violation data — you file a Request for Data Review (RDR) when you believe something on your record is wrong. That data feeds CSA scores, so a wrong violation follows you and your carrier.
The burden of proof is on you, the driver filing. Under FMCSA's reformed DataQs process, unsupported challenges can be rejected — the filings that win attach one or two decisive, dated documents: a photo from that morning that refutes the violation, or the DVIR (inspection report) from that day. A dated record made at the time beats a memory written weeks later.
Rough timeline (as of the September 2026 DataQs reform; check FMCSA for current timelines): the state typically opens a request within about 7 days, an initial decision comes in about 21 days, a reconsideration about 21 more days, and a final review about 45 days. Requests now get multi-level independent review — but only if the evidence is attached up front.
Electronic DVIRs are expressly legal under FMCSA's rule effective March 23, 2026 — and a carrier only has to keep a DVIR for 3 months. A copy you keep yourself outlives that. Save a download of each pack somewhere off this phone too (email it to yourself), in case the phone is lost.
This pack supports your own DataQs filing — Rig Pig does not file anything for you and does not promise any outcome. You file at FMCSA's DataQs site, with your evidence attached.
Your evidence records (this phone only)
Every DOT check you run is saved here automatically with its date/time, your description, the verdicts, and any photo you attached. You can also save the description and photo you've entered above as a standalone dated record — no analysis needed, works offline.

📋 How to read a job offer
- Cents per mile (CPM) is only half the story. Ask whether miles are practical (actual route) or HHG/shortest (zip-code math that pays fewer miles).
- Accessorial pay: detention, layover, tarping, extra stops. A lower CPM with strong accessorials can beat a high CPM.
- Home time: get the actual schedule in writing (e.g. "home weekly" vs "home 34 hours every 10 days" are very different lives).
- Training contracts — the big gotcha: "free CDL training" usually means you owe 9–12 months. Leave early and you owe thousands. Read the contract, not the brochure.
- Lease-purchase: be very cautious as a rookie. You take the expenses; the company keeps the control. Most experienced drivers say: drive company for a year first.

Your credentials — the other pre-trip
The truck gets a pre-trip every day. Your paperwork needs one too. At the inspection window, the violation lands on the driver holding the wheel — even in a truck you didn't choose. A missing or expired medical card is now the #1 driver out-of-service violation category (Roadcheck 2026, roughly 27–28% of driver out-of-service violations). Two minutes here beats getting parked at a scale.
🩺 DOT medical card
The paper-card era is over. The FMCSA NRII paper medical-certificate exemption ended October 12, 2026 — your medical examiner's result now has to show up in your electronic CDL record with your state, and that record is what counts. Passing the physical isn't enough if the result never transmitted.
If your state record doesn't show your medical result, call the medical examiner's office and your state licensing agency before you roll. Drivers are being sidelined right now for records that never transmitted — and a missing record isn't something you can argue at the window.
🗂️ Cab documents audit
Drop-and-hook / slip-seat? Check the trailer you just hooked — not the one you wish you had. Its inspection sticker and the cab paperwork become your problem the moment you're holding the wheel. Physically look at each one, then check it off.
