A joint Department of Transportation and Department of Homeland Security operation removed 800 unsafe commercial trucks or drivers from roads across four states over a three-day period ending Aug. 4, officials announced.
The operation, dubbed Highway Shield, is the second wave of a multi-agency enforcement initiative targeting unsafe commercial motor carrier operations. Violations triggering removal include brake failures, hours-of-service violations, drug and alcohol infractions and load securement failures.
Commercial truck crashes kill approximately 5,000 Americans annually, making unsafe trucking operations a persistent public safety threat on highways. The joint operation reflects an interagency approach that combines commercial vehicle safety inspections with immigration enforcement.
The DOT’s Federal Motor Carrier Safety Administration conducted the safety inspections, while DHS’s Homeland Security Investigations provided enforcement support. The four states where operations were conducted were identified in the official announcement.
Each of the 800 removals represents a truck or driver that federal inspectors determined posed an imminent safety hazard to other motorists. Common violations include defective braking systems, fatigued drivers exceeding legal driving hours and improperly secured cargo.
The first wave of Operation Highway Shield was conducted earlier in 2026 and resulted in similar enforcement numbers. The recurring operations signal sustained federal attention to commercial vehicle safety as a law enforcement priority.
