How do I calculate annual DOT random testing requirements?
Enter the average covered employee pool size and the applicable drug and alcohol testing rates. The calculator multiplies the pool size by each rate and rounds up to whole tests for annual planning.
What DOT mode does this calculator use by default?
The calculator defaults to FMCSA with 50% drug testing and 10% alcohol testing. You can choose other DOT agency defaults or enter custom rates.
Can random tests be completed all at once?
Random testing should be unannounced, use a scientifically valid selection method, give each covered employee an equal chance of selection, and be spread reasonably throughout the calendar year.
How does the calculator estimate time saved?
The time estimate uses the visible assumptions listed under the calculator button, including notifications, reminders, result updates, testing-cycle planning, compliance follow-up cases, and annual audit summary preparation.
