CVSA Blitz Preparation Guide — stay off the out-of-service list.

CVSA blitzes happen multiple times per year across North America. Ontario carriers that prepare in advance consistently pass at higher rates. This guide covers the most common focus areas.

How CVSA blitzes work

Blitzes are unannounced roadside inspections lasting 72 hours
Inspectors follow the North American Standard Out-of-Service Criteria
A single critical defect puts the entire vehicle out of service
Results are recorded against the carrier's CVOR profile
Historical focus areas: brakes (most common), cargo securement, hours of service, lighting

Most common brake out-of-service defects

Brake stroke exceeding adjustment limits (pushrod travel too long)
Brake lining worn below minimum thickness
Broken or missing pushrods
Air leaks exceeding 4 psi per minute in single or 6 psi in combination
Inoperative ABS on any wheel end
20% or more defective brakes on the vehicle

Pre-blitz checklist

Check and adjust all slack adjusters (measure pushrod stroke, don't guess)
Inspect all brake linings: replace anything at or near minimum spec
Pressure-test the air system (compressor to chambers)
Verify ABS warning lamp self-test on startup
Check all lamps, reflectors, and wiring connections
Inspect tires for tread depth, sidewall damage, and proper inflation
Verify cargo securement equipment (straps, chains, binders)
Review driver qualification files and hours-of-service logs
Book a pre-blitz inspection at least 2 weeks before the expected window
