Current Status of Connecticut’s Mileage-Based User Fee

Connecticut lawmakers have advanced legislation that would implement a mileage-based road usage charge specifically targeting heavy-duty commercial vehicles. The program is currently slated to begin in phases starting in 2026, with full implementation targeted for 2027-2028 depending on final regulatory approval.

For current federal guidance, see the FMCSA Regulations.The Connecticut Department of Motor Vehicles and Department of Transportation have been conducting pilot programs to test onboard diagnostic equipment, GPS-based tracking, and reporting platforms. These tests have involved volunteer trucking companies operating Class 8 tractors throughout the state. Early data suggests the system can accurately capture miles traveled on Connecticut roads while protecting driver privacy through aggregated reporting.

As of late 2025, the exact per-mile rate remains under discussion. Industry estimates project an initial rate between 1.5 and 3.5 cents per mile for trucks over 26,001 pounds GVWR. This would replace a portion of the existing diesel fuel tax for in-state travel. Rates may change based on annual legislative review, inflation adjustments, and actual road maintenance funding needs.

Fleets based in Massachusetts, Rhode Island, or other neighboring states that regularly cross into Connecticut will need to account for these new charges in their cost-per-mile calculations.

Why Connecticut Is Moving to a Truck Mileage Tax

Why Connecticut Is Moving to a Truck Mileage Tax

The primary driver behind this Connecticut truck mileage tax update is the steady decline in fuel tax revenue. As more carriers adopt electric Class 8 trucks and hybrid powertrains, traditional diesel tax collections no longer reflect actual road usage. Connecticut’s aging infrastructure, including major corridors like I-95, I-91, and I-84, requires consistent funding that a mileage-based system aims to provide.

Similar programs are already active or in advanced planning stages in several other states. Oregon, Utah, and Kentucky have operated voluntary or mandatory mileage charge pilots for years. Connecticut’s approach draws from these models but includes specific provisions for commercial fleets that frequently operate across New England state lines.

For logistics decision-makers, this represents both a challenge and an opportunity. Accurate mileage reporting could lead to more equitable cost distribution across the industry. However, it also adds another layer of administrative burden at a time when driver shortages and supply chain complexity already strain operations.

New England fleets that run dedicated lanes through Hartford, Bridgeport, or Stamford will see the most immediate impact. Construction companies moving equipment between job sites in southern Connecticut and neighboring states should also prepare for adjusted budgeting.

How the Connecticut Truck Mileage Tax Will Work

How the Connecticut Truck Mileage Tax Will Work

For more on this topic, see our guide on Rhode Island fuel tax 2026.Under the proposed framework, participating carriers would install approved electronic logging devices or telematics systems that record miles traveled within Connecticut. These systems would differentiate between taxable and non-taxable miles, potentially excluding private property, exempt routes, or out-of-state travel.

Reporting would likely occur quarterly, similar to IFTA fuel tax filings. Carriers would submit total Connecticut mileage and pay the calculated user fee. The state may offer multiple compliance options, including:

• Integrated telematics solutions already used for ELD compliance
• Standalone mileage reporting apps
• Third-party service providers that handle data aggregation and payment

Official rules and updates are published by the U.S. Department of Transportation.Payment could be handled through existing DMV portals or a new dedicated mileage tax platform. Penalties for non-compliance are expected to mirror current fuel tax enforcement, including fines, registration holds, and potential audits.

For fleets that already use advanced fleet management software, integration may be relatively straightforward. Smaller operators or independent contractors may need to invest in new equipment or partner with compliance service providers. Rates and specific technical requirements will be finalized closer to the 2026 launch, so staying in regular contact with state transportation officials is recommended.

The system is designed to work alongside existing federal and state regulations rather than replace them. FMCSA ELD rules, hours of service, and vehicle maintenance standards remain unchanged. This Connecticut truck mileage tax update focuses specifically on revenue generation for infrastructure rather than safety or emissions.

Impact on New England Fleet Operations

Impact on New England Fleet Operations

For more on this topic, see our guide on New England chassis shortage update 2026.New England carriers that cross state lines regularly will need to update their financial models to incorporate the new Connecticut charges. A typical Class A tractor-trailer running 120,000 miles per year with 25 percent of those miles in Connecticut could see additional annual costs ranging from $4,500 to $10,500 depending on the final per-mile rate. These figures vary by employer, equipment type, and actual routing.

Construction fleets moving heavy equipment between Massachusetts and Connecticut job sites may face higher proportional impacts due to frequent short-haul movements. Logistics companies operating warehouse networks in the I-91 corridor will need to evaluate whether to adjust customer pricing or absorb the cost internally.

Driver compensation and recruitment strategies may also shift. Carriers that can demonstrate efficient routing to minimize taxable miles may become more attractive to CDL drivers concerned about equipment downtime and regulatory complexity. This creates opportunities for companies that maintain strong driver support systems and clear communication about new compliance requirements.

Highway Driver Leasing helps fleets across Massachusetts, Connecticut, Rhode Island, New Hampshire, Vermont, and Maine maintain stable operations during regulatory changes by providing experienced Class A and Class B CDL drivers on both temporary and permanent placement basis. Our DOT-compliant workforce solutions allow carriers to focus on adapting to new tax structures without sacrificing delivery performance.

The mileage tax may also accelerate the adoption of routing software that optimizes for multiple variables, including fuel costs, tolls, and now state-specific user fees. Carriers that invest early in these technologies may gain competitive advantages as the program rolls out.

Preparing Your Fleet for 2026 Implementation

Fleet managers should begin preparation well before the official 2026 start date. Here are practical steps to consider:

1. Audit current routing data to determine what percentage of total miles occur in Connecticut. This baseline information will help forecast financial impact once rates are published.

2. Evaluate existing telematics and ELD systems for compatibility with potential mileage reporting requirements. Many current providers are already developing Connecticut-specific modules.

3. Budget for potential rate increases in 2026 and 2027 transportation bids. Building these costs into customer contracts now prevents margin erosion later.

4. Train dispatchers and operations staff on the new reporting procedures. Clear internal processes will reduce errors during the initial implementation period.

5. Consider partnering with staffing providers that understand the New England regulatory environment. Access to reliable CDL drivers becomes even more valuable when operational complexity increases.

Staying informed through industry associations and direct communication with Connecticut DOT will be essential. Rules and rates may change as the program moves from pilot to full deployment, so flexibility remains important.

Smaller fleets and owner-operators should explore whether the state will offer simplified reporting options or exemptions for low-mileage vehicles. While details are still emerging, Connecticut has indicated willingness to work with various fleet sizes to ensure smooth adoption.
