Vermont DMV outlines enforcement, technology plans for commercial trucks; virtual weigh stations to expand

Good morning. On April 17, 2025, a Vermont Department of Motor Vehicles commercial vehicle enforcement official described the agency’s current enforcement work, technology investments and permitting practices and outlined plans to expand virtual weigh‑in‑motion stations to improve road safety and protect pavement.

The presentation, given by Steve Petita of the DMV’s commercial vehicle enforcement section, summarized the unit’s history and duties, described how permits and the federal bridge formula shape routing for heavy and over‑dimension loads, and explained how federal grants and new technology such as weigh‑in‑motion systems and electronic carrier screening are being used to target unsafe carriers.

Petita said the DMV enforces state laws implementing federal commercial vehicle safety rules, conducts roadside and terminal inspections, investigates crashes involving commercial vehicles, and enforces size, weight and permit conditions. He described recurring pavement damage—potholes, alligator cracking, rutting—and explained that heavier trucks cause disproportionately more pavement damage, citing the Federal Highway Administration and the federal bridge formula as the basis for state weight and routing policy.

Petita detailed two technology programs the agency is using: weigh‑in‑motion (WIM) sensors embedded in pavement and a carrier pre‑screening service the presentation called DriveWise (commonly commercialized as Drivewyze). He said the Colchester northbound virtual weigh station is functional and that the DMV plans to install additional virtual WIM stations in Coventry and White River Junction using federal discretionary technology grants. WIM sites collect continuous 24‑hour data to identify suspected overweight trucks and share data with Agency of Transportation engineers and the Federal Highway Administration for pavement planning and certification reporting.

Petita explained how the DMV uses carrier screening to focus inspections. Companies registered with the screening service are electronically pre‑screened and can bypass fixed‑site details if they show no safety anomalies; carriers outside the program or flagged by WIM are routed to scales or portable certified scales for confirmatory weighing. He described the screening tool’s “inspection selection score,” which combines inspection history, out‑of‑service placements and absence of recent inspections to prioritize enforcement.

On grants, Petita described the Federal Motor Carrier Safety Administration’s Commercial Vehicle Safety Assistance Program (MCSAP) as the core source of federal funding for statewide truck enforcement and said the DMV also uses competitive High Priority grants for targeted rural enforcement and for technology (weigh‑in‑motion, virtual screening) projects. He said compliance and reporting to FHWA are part of maintaining federal funding.

Several legislators and attendees asked operational questions. Representative Molly Burke described constituent concerns about heavy trucks on Route 9 and local permitting; Petita said state roads are covered by state statute while local roads are posted by municipalities in spring, and that the DMV and the permit office route loads based on dimensions and construction zones. Representative Ken Wells asked about standard springtime weight limits on unpaved roads; Petita said municipalities set spring postings (a typical dirt‑road limit is 24,000 pounds by local practice) and noted statutory special limits for certain bridges.

Petita described enforcement practice: WIM is a screening tool that requires confirmatory certified scales before an overweight citation is issued; portable and platform scales are used to certify weight. He reviewed inspection levels under national standards (driver credential checks, walk‑around inspections, full level‑1 inspections that include under‑vehicle brake checks) and described common out‑of‑service defects the DMV finds on Vermont roads—broken springs, cracked fifth‑wheel plates, loose or missing cargo securement, hazardous packaging, and tire and wheel failures.

He said the DMV performs crash investigations and post‑crash inspections and coordinates with other agencies—Agency of Transportation engineers on pavement and bridge assessments, the state Health Department on refrigerated food or public‑health cargo concerns, and Natural Resources for waste‑hauler compliance. He also described the Commercial Vehicle Safety Alliance (CVSA) events the state participates in, such as International Roadcheck and specialized blitzes (hazmat, safe‑driver, human‑trafficking awareness).

Petita noted technological and industry changes: electric police motorcycles in the fleet (with a limited range, approximately 60–100 miles depending on conditions), increasing in‑cab cameras and telematics that can be used for post‑crash investigations, and emerging virtual or level‑8 inspections that transmit driver, vehicle and hours‑of‑service data electronically. He said some autonomous trucking technologies are under discussion at the federal level and that regulators and industry are still adapting enforcement rules for new tech.

The presentation closed with Petita noting that overweight fines are remitted to the Agency of Transportation for road repair (municipalities that issue overweight citations receive the majority of such funds when they issue them) and that fines can be substantial—he said overweight penalties can exceed $10,000 depending on the violation, and additional escalators apply for repeat offenses or large excesses.

The DMV official concluded that continuing the mix of targeted inspections, WIM data, carrier screening and federal grant support is intended to make enforcement more efficient and to better protect road infrastructure and public safety.

The presentation opened at 00:00:31 with Steve Petita’s remarks and concluded at 01:36:32 with his closing thanks.
