FMCSR 396.5A: Oil/Grease Leak — Driver Q&A

No, not automatically. Across our 13 million inspection records, 396.5A does not carry out-of-service eligibility—meaning an inspector cannot immediately ground your truck solely for this violation. However, our data shows that 6 out of 29 all-time citations resulted in out-of-service placement (20.7% OOS rate), typically when the leak is severe enough to trigger a related defect code or when combined with other maintenance failures. For comparison, the national average OOS rate across all FMCSR codes is 31.4%, so oil leaks are less likely to result in immediate removal than many other violations.

This violation carries a CSA severity weight of 3. That means it will add points to your carrier's Vehicle Maintenance BASIC on the Compliance, Safety, Accountability (CSA) system. The exact point total depends on when the citation was issued and which 30-month rolling window it falls into—CSA weights are multiplied over time in the agency's scoring model, but 3 is the base severity assigned to this code. A single citation won't demolish your CSA score, but repeated citations will accumulate.

1. Document the leak location and severity. Take photos and note where the oil/grease is coming from (engine, transmission, transfer case, etc.).
2. Inspect related systems. Our inspection data shows 396.5A often co-occurs with brake defects, tire issues, lighting problems, and coupling device failures. Have your mechanic check brakes, tires, lights, and coupling hardware—don't assume the leak is your only problem.
3. Schedule repair immediately. Oil leaks can worsen quickly and may trigger a follow-up inspection violation.
4. Keep repair documentation. If you contest the citation through the DataQs Roadside Dispute Resolution process, proof of repair is your strongest evidence.

It's relatively low-volume but moderate in impact. Our database ranks 396.5A at #1816 out of 3,036 FMCSR codes by citation count—very infrequent compared to common violations like inoperable lamps (660,737 citations) or general maintenance failures (236,919 citations). However, the 20.7% OOS rate is notably lower than general maintenance violations (45.3% OOS), suggesting inspectors view oil leaks as less immediately dangerous than brake or inspection failures. The violation is taken seriously enough to be cited, but not typically grounds for immediate removal.

Yes, you can submit a Roadside Dispute Resolution (RDR) challenge through the Federal Motor Carrier Safety Administration's DataQs system if you believe the citation is inaccurate or unjustified. Your strongest case is demonstrating that no leak existed at the time of inspection—for example, if the inspector cited you for residual seepage that was cleaned during routine maintenance, or if the leak was in a sealed, non-hazardous area. Document the repair, get a mechanic's statement, and submit evidence of the vehicle's condition. Disputes based on repair records after citation are harder to win; the inspection result stands as observed.

Over the last 180 days, our records show Iowa led with 5 citations (1 out of service), followed by Texas, Illinois, and New Mexico with 1 citation each. Iowa accounts for the bulk of recent activity in this violation. Texas had a higher out-of-service rate in that period (100%, though from a single citation), suggesting inspectors in that state may enforce more strictly when they do cite the violation. For a driver operating regionally, Iowa is the highest-risk state.

Moderately urgent. Our 90-day trend shows only 2 citations for 396.5A in that window, indicating the violation is not epidemic—but when cited, it signals a maintenance gap. Oil leaks worsen over time and can cause engine damage, loss of lubrication, or spillage that triggers environmental citations. More importantly, if you're stopped again and the same leak is present, a second citation will compound your CSA score and increase the likelihood of future out-of-service placement on related codes. Schedule repair within 2 weeks; don't ignore it.

A 396.5A citation affects both you and your carrier. It appears on your driver record in the FMCSA PrePass and CSA system, but it also rolls up into your carrier's Vehicle Maintenance BASIC score. If you own an independent authority, the citation is yours to carry. If you drive for a fleet, your citation contributes to that carrier's safety profile, which can impact their insurance rates, federal compliance audits, and contract renewals with brokers and shippers. Fleets with poor maintenance records face increased scrutiny and penalties.
