Driver's License Test Prep
Florida Practice DUI & Impaired Driving

A driver under 21 is stopped by law enforcement. At what breath alcohol level does the driver's privilege automatically get suspended for six months?

  1. A.
    A BAL of .05, the substance-abuse course threshold.
  2. B.
    A BAL of .08, the adult DUI limit.
  3. C.
    Any measurable trace of alcohol at all, since Florida uses a true 0.00 rule for minors.
  4. D.
    A BAL of .02 or higher, the youth zero-tolerance threshold. Correct
The Why

The answer is "A BAL of .02 or higher, the youth zero-tolerance threshold."

Florida's zero-tolerance rule automatically suspends an under-21 driver's privilege for six months at a BAL of .02 or higher. Drivers who read 'zero tolerance' as a literal 0.00, the true-zero rule some other states use, land on option C instead of the .02 figure Florida actually prints.

Why the others miss

The traps in the wrong answers

A. A BAL of .05, the substance-abuse course threshold.

A .05 reading triggers the required substance abuse course; the six-month suspension already attaches at .02. Swaps the .02 suspension trigger with the .05 substance-abuse course figure printed a sentence later on the same page.

B. A BAL of .08, the adult DUI limit.

The .08 figure is the adult administrative suspension threshold, not the under-21 zero-tolerance line. Applies the adult .08 administrative suspension rule to an under-21 driver, ignoring the separate youth block on the same page.

C. Any measurable trace of alcohol at all, since Florida uses a true 0.00 rule for minors.

The zero-tolerance threshold the manual prints is .02, not a flat zero. Reads 'zero tolerance' literally as 0.00, the true-zero rule some other states use, skipping Florida's printed .02 figure.
