There is no Federal Motor Carrier Safety Administration rule requiring a first aid kit on a commercial truck. The DOT first aid kit requirements for commercial trucks that most drivers assume exist simply aren’t in the federal emergency equipment regulation. 49 CFR 393.95 lists fire extinguishers, spare fuses, and warning devices, and nothing else.1eCFR. 49 CFR 393.95 – Emergency Equipment on All Power Units That doesn’t mean you can skip the kit. OSHA workplace safety rules, state laws, and hazmat-specific medical equipment mandates fill the gap, and the practical result for most carriers is that a first aid kit is required, just not by the agency you’d expect.
What the FMCSA Emergency Equipment Rule Actually Covers
49 CFR 393.95 applies to every truck and truck tractor (with a narrow exception for vehicles towed in driveaway-towaway operations). The complete list of required items is short:
- A fire extinguisher. Trucks not hauling placarded hazmat need at least one rated 5 B:C or two rated 4 B:C. Placarded hazmat loads require a single extinguisher rated at least 10 B:C.
- Spare fuses of each type and size the vehicle uses, if it uses fuses.
- Warning devices: three bidirectional reflective triangles, or at least six fusees, or three liquid-burning flares.
No bandage, antiseptic, or CPR barrier appears anywhere in the rule.1eCFR. 49 CFR 393.95 – Emergency Equipment on All Power Units The pre-trip duty in 49 CFR 392.7 requires drivers to verify their emergency equipment is in working order before driving, but because first aid kits aren’t part of that equipment list, the pre-trip rule doesn’t create a first aid obligation either.
So if a roadside FMCSA inspection is the only thing you’re worried about, a missing kit will not generate a federal violation code or hurt your CSA score. Stop reading there and you’re setting yourself up for a much larger problem.
OSHA Treats the Cab as a Workplace
Under 29 CFR 1910.151, when no infirmary, clinic, or hospital is in “near proximity” to a workplace, the employer must ensure that someone is trained in first aid and that adequate first aid supplies are readily available.2eCFR. 29 CFR 1910.151 – Medical Services and First Aid A long-haul driver operating hours from the nearest hospital is the textbook case. The cab is the workplace, and OSHA treats it that way.
The rule is performance-based rather than prescriptive. OSHA doesn’t hand you a checklist. Instead, the employer conducts a hazard assessment of the specific operation and stocks supplies adequate for the risks the driver actually faces. A flatbed hauling steel presents different first aid needs than a dry van of consumer electronics. The flexibility is deliberate, but it also means an employer can’t just buy an off-the-shelf kit and stop thinking.
Most carriers close that gap by adopting ANSI/ISEA Z308.1, the consensus standard for workplace first aid kits. OSHA has historically accepted industry consensus standards as evidence of compliance with performance-based rules, and Z308.1 has become the de facto benchmark even though OSHA doesn’t name it in the regulation.
What Belongs in the Kit
ANSI/ISEA Z308.1-2021 defines two classes of workplace kits based on the hazard level of the environment. For commercial truck operations, both come up.
Class A Kits
Class A kits handle the everyday minor incidents: small cuts, scrapes, and minor burns. A compliant Class A kit includes adhesive bandages in multiple sizes, adhesive tape, antibiotic treatment, antiseptic packets, burn dressings, a breathing barrier for CPR, cold packs, eye coverings, medical exam gloves, hand sanitizer, roller bandages, scissors, sterile pads, and triangular bandages. For a driver whose main hazard is the cab environment, Class A is often enough.
Class B Kits
Class B kits are built for higher-risk operations where more serious injuries are foreseeable, such as drivers working around heavy equipment, construction zones, or cargo with crush or laceration hazards. A Class B kit contains everything in Class A plus larger quantities and two important additions: a splint and a tourniquet. The tourniquet is there because severe bleeding in transportation settings needs intervention that pressure bandages can’t provide. For most CMV operations, Class B is the safer default.
Hazmat Loads Trigger Additional Medical Equipment
Hauling placarded hazardous materials doesn’t add a federal first aid kit requirement, but it does add targeted medical equipment obligations. Where workers may be exposed to corrosive materials, OSHA requires facilities for quick drenching or flushing of the eyes and body within the immediate work area.2eCFR. 29 CFR 1910.151 – Medical Services and First Aid
In practice, a driver hauling acids, caustics, or other corrosives needs portable eyewash and body-flush solutions accessible from where loading and unloading occur. These don’t substitute for a first aid kit and don’t overlap with one. They address chemical burns that get worse with every second of delay. The eyewash and flush equipment sits alongside the upgraded 10 B:C fire extinguisher already required by 393.95 for placarded loads.
Stocking a Kit Creates a Bloodborne Pathogen Obligation
Here is the trap most carriers miss. Under OSHA’s Bloodborne Pathogens standard at 29 CFR 1910.1030, any employer whose workers face reasonably anticipated contact with blood or other potentially infectious materials during their duties must establish a written Exposure Control Plan.3eCFR. 29 CFR 1910.1030 – Bloodborne Pathogens
A driver expected to administer first aid to an injured coworker or crash victim fits that description. If company policy or training tells drivers to use the kit to treat bleeding injuries, the company has designated those drivers as first aid responders. That designation pulls in the full 1910.1030 package: written plan, annual training, hepatitis B vaccination offered at no cost, and proper sharps disposal. Stocking a kit without the pathogen program solves one compliance problem while creating another.
State Laws Fill the Federal Gap
A number of states and municipalities require first aid kits in commercial vehicles operating within their borders, regardless of what the federal rules say. These mandates can reach property-carrying trucks that face no equivalent federal obligation.
Details vary widely. Some states reference ANSI/ISEA Z308.1 and effectively require a commercially available workplace kit. Others list specific items by name and quantity. A few impose requirements only on certain vehicle types or operations. Fines range from modest to several hundred dollars per violation, and a citation during a roadside inspection can delay a load.
For interstate carriers, the practical approach is to carry a kit that meets or exceeds ANSI Class B, which typically satisfies even the strictest state requirements. Check each state’s commercial vehicle safety regulations before expanding into new operating areas.
How Enforcement Actually Works
During a standard FMCSA roadside inspection, officers check the 393.95 items: fire extinguishers, warning triangles or flares, and spare fuses. A missing first aid kit won’t generate a federal violation code or affect a carrier’s CSA score. If a state or local law requires a kit, though, an officer enforcing that jurisdiction’s rules during the same stop can cite the driver under state authority. The violation flows through the state’s penalty structure rather than CSA, but it still means a fine and a delay.
OSHA enforcement is where the real money sits. OSHA doesn’t run roadside stops, but an OSHA inspection of a motor carrier’s operations can include the vehicles. If an employer fails to provide adequate first aid supplies where 1910.151 requires them, the current maximum penalty for a serious violation is $16,550 per violation, and willful or repeated violations can reach $165,514 per violation.4Occupational Safety and Health Administration. OSHA Penalties These amounts are adjusted annually for inflation, and an investigation following a workplace injury where no supplies were available tends to land at the higher end.
Keeping the Kit Compliant Over Time
Buying a kit and tossing it behind the seat is where compliance starts to erode. First aid supplies expire. Antiseptic packets dry out, adhesive loses its grip, and cold packs lose their chemical charge. A kit full of expired supplies is functionally the same as no kit, and an OSHA inspector will treat it that way.
ANSI/ISEA Z308.1 requires that supplies carry expiration dates and that expired items be replaced. Build kit inspections into the regular vehicle maintenance schedule. Checking quarterly and replacing used or expired items is reasonable for most operations. Store the kit in a marked, easily accessible location, not buried under cargo or personal items. A driver who can’t reach it in an emergency might as well not have one.
Keep a simple log of kit inspections. Documenting the inspection date, what was checked, and what was replaced takes less than five minutes and creates a paper trail that demonstrates good-faith compliance if OSHA or a state inspector ever asks.
