Roadside Inspection Levels — CVSA North American Standard

The Commercial Vehicle Safety Alliance (CVSA) standardizes inspection levels across the US, Canada, and Mexico. Drivers see Levels I-VIII at weigh stations + roadside checks.

The 8 levels

Level	What it covers	Avg time	CVSA decal?
I — North American Standard	Driver + vehicle. Most comprehensive.	45-90 min	Yes, if pass
II — Walk-Around Driver/Vehicle	Driver + visible vehicle items (no under-vehicle)	20-40 min	No
III — Driver/Credential/Administrative	Driver-only: docs, HOS, ELD, license	15-30 min	No
IV — Special Study	Single-item targeted (e.g., tires only, brakes only)	Varies	No
V — Vehicle-Only (no driver present)	Terminal-yard inspection without driver	30-60 min	Yes, if pass
VI — Enhanced NAS Radioactive Materials	Required for highway-route-controlled radioactive	60-120 min	Yes
VII — Jurisdiction-Mandated Commercial Vehicle	State-specific (e.g., school bus annual)	Varies	No
VIII — North American Standard Electronic Inspection	NEW — automated electronic check via roadside cameras + telematics. No driver-officer contact.	1-5 min	Limited

Level I — The big one

Includes everything in Levels II and III plus an under-vehicle inspection. The inspector physically gets under the truck to check:

• Frame condition
• Suspension components
• Air brake plumbing
• Drive train
• Underside cargo securement

Driver portion (Level III) covers:

• CDL + medical cert
• HOS / ELD records (current day + previous 7 days)
• Drug & alcohol test compliance (Clearinghouse status)
• Shipping papers (if hazmat)
• Seatbelt usage
• Vehicle registration / IRP / IFTA / UCR

Vehicle portion covers:

• Brakes (push-rod stroke, slack adjusters, drum + lining condition)
• Tires (tread depth, sidewall, inflation)
• Wheels (rims, fasteners)
• Lights + reflectors
• Steering + linkage
• Coupling devices
• Exhaust
• Frame + body
• Cargo securement
• Fuel system

If everything passes, the inspector applies a CVSA decal (valid for 90 days). A CVSA-decaled vehicle is less likely to be re-inspected within the 90-day window.

Level II — Walk-around

Like Level I but inspector doesn't go under the vehicle. So you might miss:

• Frame cracks (only visible under)
• Suspension defects
• Brake plumbing leaks (often only visible under)

Otherwise covers driver + walk-around vehicle.

Level III — Driver-only

The driver-focused inspection. Inspector reviews:

• All driver paperwork (CDL, med cert, HOS records)
• ELD data transfer
• Drug & alcohol Clearinghouse status (looked up real-time)
• Whether the driver matches their documents
• HOS logs for current day + last 7 days

No vehicle inspection at Level III. Driver violations only.

Level IV — Special study

Targeted at a specific item. Examples:

• Brake-only inspection during a state's "Brake Safety Week"
• Tire inspection during winter safety initiative
• Speed limiter inspection
• Auxiliary fuel tank inspection

Usually triggered by enforcement initiatives or a previously-observed defect.

Level V — Vehicle-only

Performed at a terminal yard WITHOUT the driver. Inspector checks everything Level I covers except the driver portion. Often happens during fleet audits at the carrier's yard.

If the vehicle passes Level V, it gets a CVSA decal even though no driver is there.

Level VI — Radioactive materials

Required for any CMV transporting highway-route-controlled quantities of radioactive materials. Very thorough; can take 2+ hours. Special escort + route restrictions often apply.

Level VII — State-mandated

Specific to a state's regulatory framework. Examples:

• California's BIT (Basic Inspection of Terminals)
• New York's School Bus Annual Inspection
• State-specific hazmat inspections

Level VIII — Electronic (new since 2018)

A relatively new level. The CMV's electronic systems (ELD + telematics + transponder) communicate with roadside electronic scanners. The inspector verifies HOS + credentials + Clearinghouse status without physically stopping the vehicle.

If the electronic profile is clean, the truck rolls through without delay. If flagged, may be diverted for Level III or higher.

What triggers a level upgrade

A roadside encounter that starts as Level III can escalate to Level I if:

• Inspector observes a visible vehicle defect
• HOS log shows a violation requiring vehicle examination
• Driver acts suspicious or evasive
• Truck appears to have been recently in an accident

Inspector discretion

Inspectors have significant discretion. They can:

• Inspect any vehicle at any time
• Upgrade an inspection level mid-process
• Place the driver/vehicle OOS for any qualifying defect
• Issue citations for findings

Driver coaching for roadside

When a driver gets pulled in:

1. Be polite + cooperative. Hostility prolongs the inspection.
2. Have documents organized + accessible. Don't scramble.
3. Don't volunteer information. Answer what's asked.
4. Don't sign anything you don't understand. Citations can be challenged.
5. Document the inspection. Note officer name, badge, inspection level, findings.
6. Photograph the violation if you disagree (for DataQ dispute).
7. Don't argue with the OOS decision at roadside. File a DataQ dispute after.

Where this fits in X3

X3's inspections.html records each roadside inspection encountered by the fleet. The CVSA decal expiry is tracked per vehicle. Roadside violation patterns feed into the CSA scoring (csa-scores.html). Any violation can be the subject of a DataQ dispute (see the dataq-disputes skill).
