The federal roadside enforcement push known as Operation Highway Shield has expanded into Maryland and Washington, D.C., FreightWaves reported Monday. Inspectors conducted more than 1,000 inspections of trucks and buses between the two operations and flagged hundreds of safety violations.

In Maryland, the Federal Motor Carrier Safety Administration worked with state agencies to inspect 941 commercial motor vehicles. Those inspections led to 191 vehicles and 92 drivers being placed out of service for violations of federal or state safety requirements. An out-of-service order means the truck or the driver cannot continue until the problem is corrected.

Who took part

FMCSA said the Maryland campaign involved the Maryland State Police, the Maryland Transportation Authority Police, the Maryland Department of the Environment and the Comptroller of Maryland. The coordinated roadside inspections focused on safety and regulatory violations involving commercial trucks and their drivers.

The agency did not provide a breakdown of the violations. It also did not say how many drivers were disqualified for English-language proficiency problems.

What inspectors found in D.C.

In Washington, D.C., FMCSA inspectors joined Metropolitan Police Department officers to inspect large trucks and buses. A Nov. 6 enforcement update reported 125 inspections and 193 violations, including 50 out-of-service violations.

Those 50 are violations, not vehicles or drivers. FreightWaves reports the agency did not disclose how many individual drivers or vehicles were placed out of service in the District. That is why the D.C. figures should not be added to the Maryland totals as if they were the same kind of count.

Part of a wider campaign

The Maryland and D.C. operations build on earlier Highway Shield efforts. According to FreightWaves, an Oct. 27 to 29 operation in Arkansas resulted in 393 drivers and commercial vehicles being placed out of service, 183 English-language proficiency violations and 44 criminal arrests. A separate operation in Stephens City, Virginia, found 100 violations during 86 inspections, with 11 vehicles and two drivers placed out of service. Big Rig Daily covered the Arkansas operation's partial results while it was underway.

Other recent local campaigns in Virginia, Oregon and New York also produced out-of-service orders, the outlet reports. In Culpeper County, Virginia, 22 inspections turned up 148 documented violations and 14 vehicles placed out of service. In Salem, Oregon, officers inspected 12 trucks and placed nine vehicles and five drivers out of service.

What it means on the road

For truck drivers and the companies they work for, the Maryland numbers show how quickly a multi-agency inspection event can add up: about one in five inspected vehicles in that state, 191 of 941, was placed out of service until problems were fixed.
