5 Critical Points to Pass DOT Inspections Spring 2026

Inspection season intensifies in spring. Brakes, tires, lights, leaks, and paperwork — these are the most common Level 1 violations. We show you how to prepare to avoid fines and out-of-service orders.

Spring is peak DOT inspection season. Officers hit the roads and weigh stations hard, and the stats don't lie: over 20% of inspected trucks receive violations, many resulting in out-of-service orders that leave you stranded and losing money.

The good news: most violations are preventable. Here are the 5 critical points you must check BEFORE an officer pulls you over.

1. 🛑 Brake System — The #1 Violation

Brakes are the top cause of OOS orders in Level 1 inspections. Specifically:

• Brake adjustment — over 25% of allowable stroke = OOS
• Worn pads/shoes — less than ¼" material = violation
• Air leaks — drop greater than 3 PSI in 1 minute with brakes applied = OOS
• Broken/missing components — cracked brake chambers, broken springs, etc.

What to do: Inspect brakes weekly. Check stroke on ALL chambers, not just the ones that "sound funny." If you lack the knowledge, bring it to a pro. At The Truck Savers™ we do complete brake inspections as part of our free road simulator inspection.

2. 🏴 Tires — Second Most Common Violation

Officers check:

• Tread depth — minimum 4/32" on steer axles, 2/32" on other axles
• Visible damage — cuts, exposed cords, belt separation
• Illegal recaps — not allowed on steer axle
• Pressure — visibly low tires = violation

What to do: Check tires with a depth gauge weekly. Inflate to correct pressure per load. Discard any tire with exposed cords or deep cuts. A new tire set costs less than being OOS for two days.

3. 💡 Lights and Reflectors — Easy to Prevent

Seems simple, but burned-out or dirty lights are frequent violations. Officers check:

• Brake lights, turn signals, marker lights — all must work
• Headlights — both operating correctly
• Reflectors — visible, clean, not broken
• Emergency triangles — 3 on truck, in good condition

What to do: Visual walk-around daily before rolling. Carry spare bulbs in the truck. Replace them IMMEDIATELY when they burn out — don't wait for "next time I stop at a shop."

4. 💧 Fluid Leaks — Instant Red Flag

Any visible leak of oil, coolant, fuel, or hydraulic fluid raises alarms. Officers look for:

• Fresh stains under the truck
• Active dripping while parked
• Low levels of critical fluids (engine oil, coolant, power steering)

What to do: Check under the truck every morning. If you see a stain, identify the source. A minor leak today can be a $2,000 repair tomorrow. Better fix it now than be OOS in the middle of a load.

5. 📋 Documentation — Your Papers Must Be Perfect

Officers check:

• Valid CDL with correct endorsements
• Current medical card (or certification on CDL)
• Logbook/ELD — no HOS violations, device working
• Vehicle registration
• Current insurance (proof in truck)
• IFTA and permits up to date

What to do: Review your documents MONTHLY. Set a phone reminder 30 days before your medical expires. Make sure your ELD has battery and is syncing correctly. There's no excuse for paperwork violations — they're 100% preventable.
