DOT Inspection Checklist: What To Keep In The Truck (2026)

Quick answer: a DOT inspection checklist comes down to three piles, and you can run all three in about ten minutes:

• Paperwork — license, med card, logs and the ELD packet, annual, registration and cab card, IFTA, insurance, permits, shipping papers.
• Required emergency equipment — three reflective triangles and a fire extinguisher that's mounted, labeled and charged. That's what 49 CFR 393.95 still names. Spare fuses came out of that section on April 20, 2026.
• The gear that isn't required but decides how the stop goes — a working flashlight, gloves, a hi-vis vest, a tread depth gauge, a small bag of spares.

I've been driving Class A since 1999. I run local now; back when I was running brokered freight I got looked at plenty. Almost nothing that goes wrong at an inspection is dramatic. It's a dead marker light. An extinguisher with the needle in the red. A med card in the wrong bag. Small, avoidable, expensive in time.

What a Level 1 and a Level 2 inspection actually are

The levels come from the Commercial Vehicle Safety Alliance's North American Standard Inspection Program. Knowing which one you're in tells you what's about to be looked at.

Level	What it covers	What it means for you
Level 1	Full driver credentials and a complete vehicle inspection, including underneath the truck	The long one — brakes, steering, suspension, frame, exhaust, coupling, lights, tires, securement, plus every document.
Level 2	Driver credentials and a walk-around vehicle inspection	Same paperwork, same walk-around items. The inspector does not go under the vehicle.
Level 3	Driver and credentials only	No vehicle inspection. Your folder is the whole test.

The paperwork is identical across all three. That's why the folder is the highest-value ten minutes you'll spend — a Level 3 you can fail sitting still.

The paperwork side: what lives in the folder

Keep it in one place. One zippered folder in the door pocket beats paper spread across three bags — the difference between a fast inspection and a slow one is usually how long you spend digging.

• Your CDL, correct class and endorsements for what's behind you.
• Medical examiner's certificate. The rules on how med certs reach the state have changed in recent years, so what you're required to hand over can depend on your situation. Carrying a copy costs nothing.
• Record of duty status — current day plus the previous seven, ELD or paper.
• The ELD packet. Under 49 CFR 395.22(h) the vehicle needs the ELD user's manual, an instruction sheet for transferring hours-of-service data to the officer, a malfunction-reporting instruction sheet, and blank driver's records of duty status graph-grids sufficient for a minimum of eight days. All four may be carried in electronic form. The blank logs are the one I see skipped — they're a few sheets of paper.
• Current periodic (annual) inspection report or decal.
• Registration / cab card, IFTA license copy and current decals on both sides of the tractor.
• Proof of insurance and any permits the run requires.
• Shipping papers, and for placarded hazmat, emergency response information within reach of the seat.
• The last driver vehicle inspection report if defects were noted. Under 49 CFR 396.13 you're supposed to review the previous DVIR before you drive anyway.

Put a sticky note inside the cover with the expiration dates — med card, annual, IFTA, permits. Expired is the most avoidable finding there is.

The emergency equipment the reg actually names

49 CFR 393.95 is short, and it's the section that produces the equipment violations. As of 2026 it's two items, not the three most of us learned. FMCSA published a batch of deregulatory final rules in the Federal Register on February 19, 2026; two of them hit this section. Liquid-burning flares came out of the warning-device options effective March 23, 2026, and the spare-fuse requirement at 393.95(b) was removed and reserved effective April 20, 2026.

Three reflective warning triangles

The reg calls for three bidirectional emergency reflective triangles meeting FMVSS No. 125, or at least six fusees. Triangles are what almost everybody carries: they don't burn down, don't expire, and don't hit the restrictions 393.95 puts on flame-producing devices around certain loads.

What gets flagged is a cracked triangle, a missing one out of three, or a case that's been rattling in the side box with a broken stand. Open the case. Stand one up. Make sure the legs lock.

Know the placement too. Under 49 CFR 392.22, the four-ways go on immediately when you stop on the traveled portion or the shoulder, and the devices go out as soon as possible and in any event within ten minutes. Two-lane two-way: one on the traffic side about ten feet from the truck, one 100 feet back, one 100 feet ahead. Divided or one-way: one on the traffic side within ten feet of the rear, then one at 100 feet and one at 200 feet toward approaching traffic. Blind hill, curve, or obstruction, the device in that direction moves out — 100 to 500 feet.

A fire extinguisher, mounted, and actually charged

The rating in 393.95 depends on the load. Placarded hazmat needs a UL rating of 10 B:C or more. Other commercial vehicles need 5 B:C or more, or two rated at least 4 B:C each. The reg also requires it be securely mounted, readily accessible, labeled with its UL rating, and properly filled — with a gauge or indicator showing charge.

That word mounted is where drivers get written up. An extinguisher rolling around behind the seat is a finding even if it's brand new and full. Same with a cracked bracket or a pin with no seal.

Three things on the walk-around: needle in the green, pin and seal intact, bracket tight when you shake it. Flip it over and tap the bottom once a month so the powder doesn't cake.

Spare fuses — not required any more

This one changed, and it's worth knowing because a lot of checklists still in circulation are wrong. 393.95(b) used to require at least one spare fuse of each kind and size the truck needed. FMCSA removed and reserved that paragraph in a final rule published February 19, 2026, effective April 20, 2026. There is no longer a spare-fuse violation to write.

Nothing stops you from carrying them, and I still do — an assortment box costs almost nothing and a dead fuse on a Sunday is a long wait. Just don't let anyone tell you it's a citable item, and don't let it push a real check off your list.

The gear that isn't in the reg but decides how the stop goes

None of this is on the inspector's form. It's what makes the listed items pass, and what keeps you safe on a shoulder at 5 a.m.

• A flashlight that works. You can't spot a burned-out clearance light on a dark trailer with a phone screen. A handheld for looking down the trailer plus a headlamp for hands-free work under the hood is what most drivers land on — that's the setup in our flashlight and headlamp roundup. Change the batteries on a schedule, not when it dies.
• Gloves. Glad hands, tread checks, triangles out in weather. A pair you can feel a fitting through beats a pair you have to take off to do anything. Most drivers keep two — a light three-season pair and something insulated. Our work gloves roundup breaks that down.
• A hi-vis reflective vest. A vest isn't in the emergency equipment section. Whether one is required where you're standing depends on the road, the site, and the shipper or receiver's own rules, and that's not a call I'd make for you. Keep one on the back of the seat and you never have to work it out at four in the morning.
• A tread depth gauge. 49 CFR 393.75 sets the floor at 4/32 of an inch on the steering axle and 2/32 on the others. A cheap gauge turns "looks okay" into a number. Check cold, three spots across the tread, before you're at a scale house.
• A multi-tool. A loose clamp, a mud flap bracket, a marker lens. Ours are ranked in the multi-tool roundup.
• The small spares bag. Marker bulbs and lenses, glad hand seals, zip ties, electrical tape, a mud flap and hardware, a rag. That bag has ended more roadside problems for me than anything else in the truck.

Building a kit from nothing? Our trucker EDC loadout guide puts the light, gloves, and multi-tool together as one set instead of three separate decisions.

What commonly gets flagged for something small

Every one of these is visible from outside the truck before you ever roll.

1. Lights. Clearance, marker, brake, turn, trailer tag lamp. Walk it with the four-ways on, then read the brake and turn off a trailer beside you.
2. Tires. Depth below the 393.75 minimums, exposed belts, sidewall cuts, flat or badly mismatched duals. Thump plus a gauge, not thump alone.
3. The extinguisher. Not mounted, gauge low, label unreadable.
4. Triangles. Two in a case of three. I've opened a case and found two more than once.
5. Leaks. Fresh oil, coolant, or fuel wet under a parked truck draws an inspector's eye first.
6. Mud flaps and brackets. Torn, missing, or dragging. A lot of this is state-level rather than federal, so it varies, and it's cheap to fix in a lot.
7. Paperwork gaps. Expired med card, no annual on file, missing IFTA decals, no blank paper logs in the ELD packet.
8. Securement. Cut straps, stretched chain links, an unsecured binder.

The ten-minute version, in order

Folder first. Then equipment — extinguisher green, pinned, tight; triangle case, three, legs lock. Then lights, four-ways on, both sides, brake and turn. Then gauge the steers and drives. Then underneath for wet spots, mud flaps, fifth wheel, air lines. Last, the grab bag: flashlight on, vest on the seat, gloves in reach.

Same order every time. Order is what makes it fast, and fast is what makes it something you still do on the mornings you're already behind.

FAQ

How many fire extinguishers does a semi truck need?

Under 49 CFR 393.95, one rated 5 B:C or more covers most commercial vehicles, or two rated at least 4 B:C each. Placarded hazmat requires 10 B:C or better. Either way it has to be mounted, accessible, labeled with the UL rating, and charged.

Do I still have to carry spare fuses?

No. FMCSA removed and reserved the spare-fuse paragraph at 49 CFR 393.95(b) in a final rule published February 19, 2026, effective April 20, 2026. Carrying them is still a good idea; it just isn't a requirement, and older checklists have not all caught up.

Do I have to carry triangles if I have fusees?

49 CFR 393.95(f) accepts either three bidirectional reflective triangles meeting FMVSS No. 125 or at least six fusees. Liquid-burning flares were removed as an option effective March 23, 2026. Triangles are the practical choice for most drivers, and fusees are restricted around certain loads.

Is gear I buy for the truck a business expense?

Required equipment and tools bought for the truck are generally deductible for owner-operators and leased-on drivers, but how any specific item is treated depends on your situation. Keep the receipt, log it the day you buy it, and ask your CPA.

Bottom line

One folder, three triangles that stand up, an extinguisher green and tight in its bracket. That part of an inspection is entirely inside your control, and it takes ten minutes. The gear that isn't in the reg — a flashlight, gloves, a vest, a gauge, a bag of spares — is what lets you fix the small stuff in the lot instead of standing there looking at it. Start with the light and the gloves, add a multi-tool, and the rest of the in-cab kit is in our gear index and the EDC category.

General education for working drivers, not legal advice. The regulations referenced here — 49 CFR 393.95, 392.22, 393.75, 395.22, and 396.13 — are the authority, and state rules can add to them. They also change: 393.95 was amended twice in 2026. Checked against the current text of those sections in August 2026. When it matters, read the reg yourself or ask your carrier's safety department.
