Practical calculators and references built to support better decisions on the road, in the yard, and at the desk.
Built for the decision in front of you
Clear answers.
Fewer guesses.
These free tools turn common road, weight, time, and compliance questions into quick estimates. They are designed for drivers, dispatchers, safety teams, and operations leaders who need useful context without digging through a spreadsheet.
Tank calibration chart
Build printable fill and remaining-volume charts for horizontal, vertical, or rectangular tanks.
Load planning↗Tanker axle estimator
Explore how product, compartment loading, and baseline weights may affect steer, drive, and trailer axles.
Weight planning↗Axle / fifth-wheel shift
Estimate how tandem or fifth-wheel adjustments may redistribute weight before heading back to a scale.
Weight planning↗Fuel weight calculator
Convert fuel gallons into estimated added weight using common or custom density values.
Reference↗Weight limits reference
Review common federal and rule-of-thumb weight limits with practical safety-margin reminders.
Trip planning↗Trip feasibility checker
Compare miles, realistic average speed, available hours, stops, and buffer time before accepting a plan.
Decision support↗Speed versus time
See how little time higher speeds may save after distance and planned stops are considered.
Risk awareness↗Following-distance risk
Explore reaction distance, stopping estimates, road conditions, and the risk created by a shrinking gap.
Risk awareness↗Weather risk estimator
Explore how rain, snow, ice, speed, and reaction time can change stopping distance and following-space needs.
Business impact↗Violation cost reality
Estimate the broader cost of a violation, including downtime, missed miles, administration, and other impacts.
Risk awareness↗Stopping-distance estimator
Compare perception-reaction distance and braking distance at different speeds and deceleration rates.
Compliance reference↗Bridge formula calculator
Estimate a federal bridge-formula result based on axle count and axle-group length.
Load planning↗Load density calculator
Convert common volume units and estimate load weight using product density.
Hours of service↗30-minute break checker
Review driving hours and qualifying non-driving time against a simple break-status estimate.
Use estimates responsibly
A better question is still only the beginning.
