Florida DOT Inspection Checklist: Complete Guide

Let me be honest with you: DOT inspections are not something you want to gamble on. I’m Albert, and I run Albert’s Road Service out of West Palm Beach. I see the aftermath of failed DOT inspections every week — trucks put out of service, drivers sidelined, companies hit with fines and CSA points that follow them for years. The worst part? Most of the violations I see are completely preventable.

Florida is aggressive about commercial vehicle enforcement. The Florida Highway Patrol’s Commercial Vehicle Enforcement unit operates weigh stations and conducts roadside inspections throughout Palm Beach County, Broward County, and the entire I-95 corridor. They don’t mess around, and they know exactly what to look for.

This guide covers every major item on a DOT Level I inspection — the most comprehensive type — with Florida-specific notes that matter. Use it as your pre-trip bible.

Understanding DOT Inspection Levels

Before we get into the checklist, you need to understand what you might face:

Level I — Full Inspection: Everything. Driver credentials, vehicle systems, and under-vehicle. This is the one you need to prepare for. Takes 45-60 minutes.
Level II — Walk-Around: Driver credentials plus a visual walk-around. No crawling under the truck. Takes 15-30 minutes.
Level III — Driver Only: Credentials, logs, medical card, license. Vehicle stays parked.
Level IV — Special Inspection: One-time examinations, usually focused on a specific recall or issue.
Level V — Vehicle Only: No driver present. Vehicle inspection only, often done at terminals.

Level I and Level II are what you’ll most commonly encounter at Florida weigh stations and roadside checks.

Part 1: Driver Documentation

This is where many inspections go wrong before the officer even looks at the truck.

CDL and Endorsements

Valid CDL for the class of vehicle you’re operating
Proper endorsements (H for hazmat, T for doubles/triples, P for passenger, N for tanker)
CDL not expired, suspended, or revoked
Must be issued by your state of domicile

Medical Certificate

Valid DOT medical certificate (the long form)
Must be current — not expired
If you have a medical waiver or exemption, carry the documentation
Florida requires your medical certificate to be on file with the DMV that issued your CDL. If it’s not, you’re technically operating without a valid CDL.

Hours of Service (HOS)

Current ELD records or paper logs (if exempt)
Last 7 or 8 days of records available
No HOS violations at time of inspection
Form and manner violations (missing data fields, wrong entries) count against you
Florida note: I-95 through South Florida has heavy enforcement zones near the Port of Palm Beach and Port Everglades. Inspectors in these areas are very familiar with HOS games.

Part 2: Brake Systems — The #1 Out-of-Service Violation

Brakes are the single most common reason trucks get put out of service in Florida and nationwide. This is where you need to be most diligent.

Service Brakes

Pushrod stroke: This is the big one. Automatic slack adjusters that aren’t maintaining proper stroke length cause more OOS violations than anything else. Know your brake chamber size and the max allowable stroke:

Chamber Size	Max Stroke (Applied)
Type 16	1.75”
Type 20	1.75”
Type 24	1.75”
Type 30	2.0”
Type 36	2.5”

Brake linings: Minimum 1/4” thickness for drum brakes. No cracks, contamination (oil/grease), or missing linings.
Brake drums: No cracks exceeding 50% of the width between the open edge and the nearest bolt hole. No external heat checking that compromises integrity.
Brake hoses and tubing: No leaks, cracks, bulges, or chafing. Connections tight and secure.
Brake chambers: No air leaks. Clamp bolts tight. No cracks in the chamber housing. Push rod not bent.

Air Brake System

Air compressor: Building air properly. Governor cutting in at 100 PSI and out at around 125 PSI.
Air dryer: Functioning properly. No excessive moisture in the system. Florida’s humidity makes this critical — a waterlogged air system will corrode valves and freeze up (yes, even in Florida, when moisture hits the rapid pressure drop at the brake valves, it can cause issues).
Air pressure gauges: Working and accurate. Must read within spec.
Low air pressure warning: Must activate at 60 PSI or above. Test this.
Air loss rate: With the engine off and brakes applied, air loss cannot exceed 3 PSI per minute for single vehicles or 4 PSI per minute for combinations. This is a critical test that inspectors will perform.
Tractor protection valve: Must close between 20-45 PSI. This prevents total air loss to the trailer.
Spring brakes: Must apply automatically when air pressure drops below 20-45 PSI.

Parking Brake

Must hold the vehicle on a grade
Spring brakes must be functional on all required axles

Pro tip: If your brakes are marginal, get them serviced before you get caught. I do roadside brake repair all the time — slack adjusters, brake chambers, and brake shoes can all be replaced on-site. It’s a fraction of the cost of an OOS violation and the tow to a shop. Call 561-475-8052 for mobile brake service.

Part 3: Tires and Wheels

Tires

Tread depth: Steer tires must have at least 4/32” in every major groove. All other tires must have at least 2/32”.
Tire condition: No exposed cords, belt material, or ply. No sidewall cuts or bulges that expose the cord.
Inflation: Tires must be properly inflated. Flat or obviously underinflated tires are an OOS violation.
Matching: Tires on the same axle should be similar in size and type. Mixing radial and bias-ply on the same axle is a violation.
Retreads: Retreads are NOT allowed on the steer axle. This is a common violation I see.
Load rating: Tires must be rated for the load they’re carrying.

Florida note: Heat is the number one killer of truck tires in South Florida. Pavement temperatures on I-95 in summer can exceed 150°F. I recommend running 5-10 PSI above minimum on hot days and checking pressure when tires are cold (before driving). Underinflated tires in Florida heat equals blowouts — it’s not a question of if, but when.

Wheels and Rims

No cracks or breaks in the rim
No missing, loose, or broken lugs or stud bolts
Lug nuts properly torqued (check for rust streaks around the lugs — a sign of loosening)
Hub seals not leaking
No visible bearing damage or heat discoloration

Part 4: Steering System

Steering wheel play: Maximum free play for power steering systems is typically 2” of play for a 20” steering wheel. Inspectors measure this with the wheels in the straight-ahead position.
Power steering: Fluid level adequate. No leaks in hoses, pump, or gear box. Belt driving the pump in good condition.
Steering gear box: Mounted securely. No excessive play. No leaks.
Tie rod ends and drag link: No excessive play. Ball joints not worn. Boots not torn.
Kingpins: No vertical or horizontal play beyond spec. This gets checked on Level I inspections with the wheels off the ground.
Steering column: No looseness or binding.

Part 5: Suspension

Leaf springs: No cracked, broken, or missing leaves. Main leaf and any leaves within 2 of the main leaf count as OOS if broken.
Air springs (bags): No leaks, cracks, or deflated bags. Air lines to the bags secure and not chafing.
Shock absorbers: Not required on all trucks, but if equipped, they should not be leaking or disconnected.
U-bolts and hangers: Tight and not cracked. Spring hanger brackets secure to frame.
Torque arms and radius rods: Secure and not cracked. Bushings intact.
Frame: No cracked, bent, or broken frame rails. No unauthorized modifications (welding, drilling) that compromise integrity.

Part 6: Lighting and Electrical

All of the following must be present and working:

Headlights (both low and high beam)
Taillights
Brake lights
Turn signals (front, rear, and fender-mounted)
Clearance lights (front and rear — amber front, red rear)
Side marker lights (amber front, red rear)
License plate light
Reflectors (as required by FMCSA)
4-way hazard flashers
Identification lights (3 amber front, 3 red rear on vehicles over 80” wide)

Common Florida issue: The salt air along the coast corrodes lighting connections fast. I see corroded ground wires causing intermittent lighting failures all the time in the Palm Beach area. A $5 ground wire fix can prevent a $500 violation.

Part 7: Exhaust System

No leaks in the exhaust system under the cab or sleeper
Exhaust must discharge at or beyond the rearmost part of the cab
No holes, cracks, or loose connections in the exhaust piping
DPF and aftertreatment components securely mounted and not leaking

Part 8: Coupling Devices (Tractor-Trailer)

Fifth wheel: Properly greased. Locking jaws engaged around the kingpin. No cracks in the fifth wheel plate. Mounting bolts tight. Pivot pins secure.
Kingpin: Not worn beyond spec (typically 2” minimum diameter). No cracks or deformation.
Drawbar/pintle hook: (if applicable) Properly latched. Safety chains in place.
Glad hands: Properly connected. No air leaks. Rubber seals in good condition. Dummy glad hands stored when not in use.
Safety chains/cables: Required on converter dollies and some trailer combinations.

Part 9: Windshield and Wipers

No cracks, chips, or discoloration in the driver’s primary viewing area (the swept area of the wipers)
Wipers must be functional and capable of clearing the windshield
Washer fluid reservoir filled and spray nozzles working

Florida note: Afternoon thunderstorms from May through October hit fast and hard in South Florida. Your wipers need to handle torrential rain, not just a light mist. Replace worn wiper blades before inspection season.

Part 10: Fuel System

No fuel leaks anywhere — tank, lines, fittings, or injectors
Fuel cap present and sealing properly
Fuel tank securely mounted with no cracks
Fuel crossover lines (if dual tanks) in good condition

Part 11: Load Securement

If you’re loaded, inspectors will check:

Tiedowns: Minimum one tiedown for articles 5’ or shorter, two tiedowns for articles 5-10’, and additional tiedowns for longer loads (one per additional 10’)
Working load limit: Total WLL of all tiedowns must equal at least 50% of the cargo weight
Tiedown condition: No knots, fraying, or damage that compromises strength
Headerboard/bulkhead: If required, must be capable of withstanding the forward force
Coils, lumber, metal, and other commodities have specific securement requirements under FMCSA Part 393

Florida-Specific DOT Notes

Here’s what makes Florida inspections different from other states:

Year-round enforcement. No “slow season.” Florida runs inspections 365 days a year.
Weigh station locations in South Florida:
- I-95 SB near Hobe Sound (Mile Marker 88)
- I-95 NB near Deerfield Beach (Mile Marker 65)
- Florida Turnpike — multiple locations
- Port of Palm Beach approaches
- Port Everglades approaches
CVSA International Roadcheck Week (usually early June) — Intensive 72-hour inspection blitz. Every year, Florida leads the nation in OOS violations during this event. Be ready.
Overweight enforcement — Florida aggressively enforces weight limits, especially on bridges. I-95 overpasses and the Intracoastal Waterway bridges have posted limits.
Hazmat routes — Certain hazmat loads are restricted from specific routes through Palm Beach County. Know your route before you roll.

Pre-Inspection Checklist: 15-Minute Walk-Around

Do this every time before you hit the road. Every. Single. Time.

Walk around the truck and trailer completely
Check all lights — have someone watch while you activate each one
Check tire condition and inflation visually (and with a gauge weekly)
Look under the truck for fresh leaks (oil, coolant, fuel, air)
Check brake pushrod stroke on accessible wheels
Inspect all tiedowns and cargo security
Verify glad hand connections and listen for air leaks
Check fifth wheel locking jaws
Verify mirrors, windshield, and wipers
Review all documentation — CDL, medical card, registration, insurance, logs

What Happens If You Fail

If an inspector places your vehicle out of service:

You cannot move the truck until the violations are corrected
The violations go on your CSA score and stay for 2 years
Your carrier gets the violation too — affects their SMS scores and can trigger audits
Fines range from a few hundred dollars to $16,000+ per violation for repeat offenders
Drivers can be personally fined and have endorsements revoked for serious violations

The cost of an OOS violation is not just the fine. It’s the tow, the shop bill, the hotel, the missed load, the detention charges, and the CSA points that make your insurance go up for the next two years. We’re talking $3,000 to $10,000+ in total impact for a single failed inspection.

Get Inspection-Ready With Mobile Service

Here’s my recommendation: Don’t wait until you’re sitting at a weigh station wondering if you’ll pass. Get a DOT inspection done proactively. I offer mobile DOT inspection prep and annual inspections at your location — your yard, your terminal, or wherever your truck is parked.

I’ll go through every item on this list, fix what needs fixing on the spot, and give you the confidence that you’ll pass when it counts. Most inspection prep takes 1-3 hours and costs a fraction of what a failed inspection would.
