Avoid DOT Violations: What Inspectors Check During Roadside Inspections

Roadside inspections can happen anytime.

Being prepared can save you time, money, and stress.

1. DOT Number Visibility

Your DOT number must be clearly visible and readable from 50 feet.

• High contrast lettering
• No fading or peeling
• Placed on both sides of the vehicle

If inspectors can’t read your numbers quickly, it can raise a red flag immediately.

2. Driver Credentials

Inspectors will check that the driver is properly licensed and qualified.

• Valid CDL (if required)
• Medical certificate
• License status

3. Hours of Service (HOS)

Logs are one of the most common areas for violations.

• Electronic logging device (ELD)
• Paper logs (if applicable)
• Compliance with driving limits

4. Vehicle Condition

The condition of your vehicle is a major part of any inspection.

• Brakes and air systems
• Tire condition and tread depth
• Lights and signals
• Steering and suspension components

5. Load Securement

If you’re hauling cargo, inspectors will check how it’s secured.

• Straps, chains, and tie-downs
• Proper weight distribution

6. Required Equipment

You must carry required safety equipment at all times.

• Fire extinguisher
• Reflective triangles
• Spare fuses (for older vehicles)

7. Paperwork

Make sure your documents are current and accessible.

• Registration
• Insurance
• Bill of lading (if applicable)

Why DOT Numbers Still Matter

Your DOT numbers are one of the fastest things inspectors can check from a distance.

If they’re hard to read, poorly placed, or damaged, it can be the first sign of non-compliance and may lead to a deeper inspection.

Final Thoughts

Roadside inspections don’t have to be stressful if your vehicle is prepared.

Staying compliant starts with the basics, and clear, readable DOT numbers are one of the easiest things to get right.
