🚛 How does DOT random drug testing REALLY work?
Many drivers think being tested once means they're "done" for the year.
That's not how random testing works. 👇
🎯 Every driver in the pool must have an equal chance of selection.
🔄 A driver can be selected more than once.
📅 Selections must be spread throughout the year.
📊 For 2026, FMCSA's minimum annual rates are:
• 50% for random drug testing
• 10% for random alcohol testing
The percentages don't mean every driver gets tested once. They're annual minimum rates based on the average number of driver positions.
So how does the selection process actually work—and how is the annual rate calculated?
