For a broader look at how technology is reshaping construction workflows, see our coverage of Innovations and Technologies Shaping the Work of Civil engineers and construction teams.
1. How Autonomous Technology Bridges the Labor Gap in Commercial Trucking
The construction and commercial vehicle industries have faced a persistent labor shortage for years. Beyond the difficulty of attracting new talent, a demographic challenge known as the silver wave threatens to accelerate the problem: a generation of experienced operators is approaching retirement, taking decades of expertise with them. Work Truck Week 2025 highlighted autonomous and semi-autonomous technology as a primary strategy for addressing this gap.
The Silver Wave and the Knowledge Transfer Problem
Adam Woods, general manager of innovation and product portfolio strategies at Link-Belt, addressed this issue directly during the Green Truck Summit session titled “Beyond the Road: Autonomous Technology Insights From Agriculture, Construction and Mining Sectors.” Woods explained that the labor gap is not simply a numbers problem: it is a skills and experience problem. New operators entering the workforce lack the accumulated knowledge that retiring veterans possess, and this gap directly affects productivity and safety on job sites.
Autonomous technology offers a path forward by augmenting the capabilities of less experienced workers. Instead of replacing human operators, these systems assist them in performing complex maneuvers, maintaining consistent performance, and avoiding common mistakes.
Levels of Autonomy in Work Trucks
Autonomous technology exists on a spectrum. Not every fleet needs full self-driving to benefit from automation. The following table outlines the common levels of autonomy relevant to work trucks and construction equipment:
| Level | Name | Description | Example Application |
|---|---|---|---|
| Level 1 | Driver Assistance | Vehicle supports one function (e.g., adaptive cruise control) | Highway cruising for delivery trucks |
| Level 2 | Partial Automation | Vehicle controls steering and acceleration simultaneously | Lane keeping plus adaptive cruise |
| Level 3 | Conditional Automation | Vehicle handles all driving under specific conditions | Automated operation on closed job sites |
| Level 4 | High Automation | Vehicle operates without human input in defined geofenced areas | Autonomous material hauling at mining sites |
| Level 5 | Full Automation | Vehicle performs all driving tasks in all conditions | Long-term industry goal, not yet realized |
For most fleet operators, Levels 2 and 3 are the most practical near-term investments, reducing the skill burden on new operators while keeping a human in the loop.
Productivity Gains Beyond Labor Replacement
Woods noted that while manufacturers may pursue autonomy for different reasons, the core driver is improving productivity and efficiency. Autonomous features allow work to continue in low-visibility conditions, reduce operator fatigue during long shifts, and optimize fuel consumption through consistent driving patterns. These benefits apply even when staffing levels are adequate, making autonomy a strategic investment rather than merely a labor contingency plan.
2. The Shift Toward Higher-Voltage Electric Powertrains
Electric vehicles are now common across the construction and commercial vehicle landscape, but the technology continues to evolve. One critical debate at Work Truck Week 2025 centered on optimal powertrain voltage levels. As battery-electric trucks move from pilot programs to fleet adoption, charging speed and infrastructure compatibility have taken center stage.
Why Voltage Matters for Charging Speed
During the Green Truck Summit session “Applied Technology: Paving the Path to Emission-Free Work Trucks Through Industry Co-Creation,” Kevin Otzenberger, product marketing manager at Daimler Truck North America, shared insights on the voltage trends the industry is likely to follow. Powertrains currently span a wide range of voltages, but the consensus is moving toward higher voltage architectures.
“We see the advantages of 600 and up voltages for fast charging, which is going to be a critical piece of the puzzle going forward,” Otzenberger said. “So I think you will see less of the 400 much more of the 600 and 800 variety.”
Higher voltage enables faster charging without requiring proportionally thicker cables or heavier cooling systems. For fleet operators, this translates to reduced downtime and more efficient use of charging infrastructure.
Comparing 400V and 800V Architectures
The shift from 400V to 800V systems brings several practical advantages:
- Faster charging times. An 800V system can accept the same power at half the current, reducing charge times by up to 50 percent compared to 400V systems with equivalent charging hardware.
- Reduced thermal load. Lower current means less heat generation in cables and connectors, improving safety and reducing cooling system complexity.
- Lighter cabling. Thinner gauge wires can be used at higher voltages, reducing overall vehicle weight and increasing payload capacity.
- Future-proof infrastructure. Investing in 800V-capable charging stations positions fleets for the next generation of electric trucks that will ship with these systems as standard.
Infrastructure Considerations for Fleet Operators
Higher-voltage systems also require upfront investment in compatible charging infrastructure. Fleet operators evaluating electric trucks should consider:
- Audit existing depot electrical capacity to determine whether upgrades are needed for 600V+ charging.
- Evaluate vehicle duty cycles to match charging speed requirements with daily route lengths and downtime windows.
- Consult with utility providers about peak demand charges and potential incentives for off-peak charging schedules.
- Plan for phased deployment, starting with routes where electric trucks can deliver the fastest return on investment.
3. Adopting a Multi-Fuel Strategy for Work Truck Fleets
While battery-electric vehicles dominate headlines, the path to zero-emission commercial trucking is unlikely to rely on a single fuel type. A recurring theme at Work Truck Week 2025 was the need for a multi-fuel approach matching energy sources to vehicle applications, regional infrastructure, and operational demands.

No Silver Bullet for Zero Emissions
During the “Achieving Zero-Emission Targets” session at Green Truck Summit, Alex Woodrow, managing director at Knibb, Gormezano and Partners, delivered a sobering assessment of the alternative fuel landscape.
“You are going to need a multi-fuel approach. It is not one size fits all, there is no silver bullet,” Woodrow said. “You are going to have to have a range of different fuels across different vehicle segments, across different parts of the market, and even within the U.S., different states will have different energy availability.”
This perspective acknowledges a reality fleet operators already contend with: energy infrastructure varies dramatically by region across the United States. A solution that works in California, with its extensive charging network, may not be viable in rural areas where diesel remains the most accessible fuel.
Fuel Options and Their Best Use Cases
The multi-fuel strategy encompasses several energy sources, each suited to specific operational profiles:
- Battery electric. Best suited for short-range, predictable routes with access to depot charging. Ideal for last-mile delivery, utility service trucks, and municipal fleets operating within a limited geographic area.
- Hydrogen fuel cell. Suitable for longer-range applications where battery weight and charging time are limiting factors. Hydrogen offers faster refueling times and higher energy density, though refueling infrastructure remains limited.
- Renewable diesel and biodiesel. Drop-in replacements for conventional diesel that require no vehicle modifications. These fuels reduce lifecycle emissions and are widely available through existing fuel distribution networks.
- Compressed natural gas (CNG) and renewable natural gas (RNG). Established alternatives with mature infrastructure, particularly for heavy-duty trucks operating in fixed routes such as refuse collection and port drayage.
Building a Resilient Fleet Energy Plan
Fleet operators should consider a phased, multi-fuel approach:
- Analyze current vehicle usage patterns to categorize routes by length, terrain, and payload requirements.
- Map available fueling and charging infrastructure in each operating region to identify realistic fuel options.
- Pilot two or three fuel technologies in parallel across different vehicle segments before committing to a single pathway.
- Monitor regulatory developments at the state and federal level, as incentive programs and emissions mandates will influence the economics of each fuel option.

4. Preparing Your Fleet for the Future of Work Trucks
The trends at Work Truck Week 2025 point to a future where work trucks are smarter, cleaner, and more adaptable. For fleet operators and construction business owners, staying competitive will require strategic planning across multiple dimensions.
Integrating Technology and Workforce Development
The labor gap will not be solved by technology alone. Autonomous systems and driver-assist features can reduce the experience burden on new operators, but they must be paired with deliberate training programs. Fleets that invest in both technology and workforce development will see the greatest returns. This means not only purchasing vehicles with advanced features but also training operators to understand and trust these systems.
As the Future of Concrete Construction Innovations in Materials demonstrates, the construction industry is embracing new technologies across every domain, from materials science to fleet management.
Evaluating Total Cost of Ownership for New Powertrains
The shift to electric and alternative-fuel vehicles changes the cost equation for fleet ownership. While battery-electric trucks have higher upfront prices, lower fuel and maintenance costs can deliver savings over the vehicle lifecycle. Key factors to consider include:
- Vehicle purchase price and available incentives at the federal, state, and local levels
- Charging or fueling infrastructure installation costs
- Energy costs per mile compared to diesel over the expected vehicle lifespan
- Maintenance savings from fewer moving parts in electric powertrains
- Resale value projections as the secondary market for electric trucks matures
Staying Informed on Regulatory and Market Trends
Emissions regulations at the EPA and California Air Resources Board levels continue to tighten, creating both compliance obligations and opportunities for early adopters. Fleet operators should monitor the following developments:
- EPA Greenhouse Gas Emissions Standards for heavy-duty vehicles, which set progressively stricter targets through 2032 and beyond.
- Advanced Clean Trucks regulations adopted by multiple states, requiring manufacturers to sell increasing percentages of zero-emission vehicles.
- Incentive programs such as the EPA Clean School Bus Program and state-level voucher schemes for electric truck purchases.
- Infrastructure investments under the Bipartisan Infrastructure Law that expand charging and hydrogen refueling networks along major freight corridors.
The Work Truck Week 2025 show floor demonstrated that the industry is not waiting for a single solution. Manufacturers are investing across multiple technology pathways, and this diversity is itself a strength. For contractors and fleet managers, the key is to stay engaged with industry events, evaluate technologies against real operational needs, and build flexibility into fleet planning. The future of work trucks will be shaped by the decisions fleet operators make today, and events like Work Truck Week provide the insights needed to make those decisions well.
