Weigh My Truck

Weigh My Truck: Mobile Axle Weight Management for Commercial Drivers

Weigh My Truck is a mobile application designed to assist commercial truck drivers and fleet operators in accurately estimating vehicle axle weights without requiring a physical truck scale. The app uses device sensors, vehicle specifications, and load input to calculate weight distribution, helping users comply with legal weight limits and avoid overweight fines.

Chapter 1: Function

The core function of Weigh My Truck is to provide axle weight estimations based on user-provided data. Users input their truck type, trailer configuration, axle spacing, and estimated cargo load. The app then processes this information, along with tilt data from the phone's accelerometer, to calculate the weight on the steer, drive, and trailer axles. It also includes a load distribution tool that allows users to adjust cargo positioning to visualize how it affects axle weights. Additional features include a log for recording weigh station results and a reference section for state-specific weight limits. The app does not replace certified scales but offers a preliminary check to help drivers make informed loading decisions before hitting the road.

Chapter 2: Value

Weigh My Truck delivers significant value by reducing the risk and cost associated with overweight violations. Overweight fines can be substantial, and repeated violations can lead to increased insurance premiums or regulatory scrutiny. The app empowers drivers to perform quick, self-service weight estimates at any cargo loading location, eliminating the need for frequent trips to public scales. This saves time and fuel, directly improving operational efficiency for owner-operators and small fleets. A key advantage is its focus on axle weight compliance rather than gross vehicle weight alone, as many fines result from uneven load distribution. The app also promotes safety by helping drivers avoid unsafe overloading that can affect braking and handling. By integrating state-specific regulations, it aids in routing decisions, allowing users to select roads with appropriate weight limits. While not a substitute for legal-for-trade scales, its convenience and accessibility make it a practical tool for daily pre-trip checks and load planning, contributing to overall fleet profitability and regulatory compliance.

Chapter 3: Scenarios

The primary target users of Weigh My Truck are owner-operators and small to medium-sized fleet managers who handle multiple load types. Typical use cases include: first, a driver loading a mixed freight at a warehouse without a dedicated truck scale; the driver inputs cargo weight and adjusts placement in the app until the estimated axle weights fall within legal limits for the planned route. Second, a flatbed driver securing a load with non-uniform weight distribution; the app helps determine whether axle groups are balanced before departing. Third, a fleet manager reviewing daily load plans for several trucks, using the app to quickly validate that dispatcher-assigned loads will not cause overweight issues at DOT weigh stations. Fourth, a dump truck operator checking loaded axle weights before entering a scale on a job site to ensure they are not grossly over the limit. The app is also used by drivers new to the industry who are learning to manage load distribution, serving as an educational tool that builds understanding of how cargo placement affects weight compliance.
