FMCSR 393.60(d) Glazing/Window Obstructions: Driver Q&A

No. Across all 37,236 citations in our inspection records for 393.60(d), only 1 vehicle was ever placed out of service—an OOS rate of effectively 0.0%. Compare that to the all-FMCSR average of 31.4% and it's clear this violation almost never pulls a truck from the road. You'll get the citation on your record, but inspectors are not directing drivers to park over a cracked or obstructed window. That said, "almost never" is not "never," so don't ignore a severe obstruction that blocks your line of sight.

393.60(d) carries a severity weight of 4 in the FMCSA SMS scoring system. That 4-point base gets multiplied depending on how recently the inspection occurred—violations from the last 6 months carry the heaviest multiplier (3×), dropping to 2× between 6 and 12 months, and 1× from 12 to 24 months. The points fall under the Vehicle Maintenance BASIC and affect both the carrier's SMS percentile and the driver's PSP record. Because the code pulled 37,236 all-time citations and ranks #88 out of 3,036 FMCSR codes, inspectors know it well and flag it consistently.

Act the same day the citation is issued. Here's a concrete checklist:

1. Document the condition — photograph the windshield or window from inside and outside before touching anything.
2. Notify your fleet or safety manager immediately so the repair is tracked and scheduled.
3. Get the glass repaired or replaced before your next trip. Our records show the violation hits FRHT and PTRB equipment most often (2,327 and 2,198 citations respectively), so shops that service those brands typically stock the right glazing.
4. Keep the repair invoice — you'll need it if you file a DataQs challenge or if the citation is re-examined.
5. Check for related windshield codes like 393.78 (windshield condition defective), which has 157,894 citations in our database and often appears alongside glazing issues.

It's common but far less dangerous to your operating authority than most peers. At a 0.0% OOS rate, 393.60(d) is far below the all-FMCSR average of 31.4%. Within the Vehicle Maintenance category alone, our inspection records show 396.3(a)(1) carries a 45.3% OOS rate across 236,919 citations, and even 393.9(a) hits 15.4% across 660,737 citations. The glazing code's 4-point severity weight is real and accumulates in SMS, but inspectors almost never sideline a truck for it. The main risk is CSA BASIC creep over time if multiple glazing citations stack up across your fleet.

Yes, and equipment-condition findings like this one are contestable. The FMCSA DataQs system lets drivers and carriers submit a Request for Data Review (RDR) to challenge the accuracy of a roadside inspection finding. For 393.60(d), the strongest grounds are: (1) the glazing was not actually cracked, discolored, or obstructed at the time of inspection, or (2) the inspector documented the wrong vehicle or wrong code. A repair invoice dated before the inspection date is powerful evidence. If the glazing was genuinely impaired, DataQs won't remove it—but correcting a clerical or factual error is a legitimate use of the process.

FRHT and PTRB vehicles top the citation list by equipment, but the data in our database does not break citations down by state for this code specifically. What our 37,236 all-time records do show clearly is which carriers accumulate the most exposure: EVANS DELIVERY COMPANY INC leads with 58 citations, followed by TRANSPORT INDIANA LLC at 45, and ACME TRUCK LINE INC at 29. If your carrier is running high citation counts in this category, that pattern is a signal that pre-trip window inspections are not being completed consistently across the fleet.

Repair it before your next run, not at your next PM interval. Our inspection records show zero citations for 393.60(d) in the last 90 days and zero in the last 12 months—a trend that tells you enforcement attention on this specific code has cooled recently. However, the 0.0% OOS rate means an inspector found the condition serious enough to cite in 37,235 of 37,236 stops without pulling the truck, which implies the violation is being written during active road operations. Driving with compromised glazing also creates real crash risk independent of the citation. Fix it now, document it, and keep the receipt.

Both. When a driver is cited for 393.60(d) at a roadside inspection, the violation appears on the driver's PSP (Pre-Employment Screening Program) record and rolls into the carrier's Vehicle Maintenance BASIC in FMCSA SMS. The carrier's SMS percentile moves because the violation is tied to the carrier's USDOT number. The driver's PSP record moves because the inspection is linked to their CDL. Our records show carriers like J B HUNT TRANSPORT INC (21 citations) and NEW PRIME INC (20 citations) accumulating fleet-level exposure, which is exactly why safety managers—not just drivers—need to own glazing compliance.
