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

You are arrested for suspected DUI. What triggers the administrative suspension of your license at the time of arrest?

  1. A.
    A BAL of .08 or above, or refusing the breath or blood test. Correct
  2. B.
    A BAL between .02 and .05 confirmed at the roadside.
  3. C.
    An officer's observation of erratic driving without any chemical test.
  4. D.
    Blowing a .05 or higher on the officer's portable breath device.
The Why

The answer is "A BAL of .08 or above, or refusing the breath or blood test."

The manual pairs the administrative suspension at arrest with two triggers: a BAL of .08 or above, or refusing the required breath or blood alcohol test. Drivers who pick D carry in the .05 figure that national safety groups have pushed as a lower legal limit and treat it as Florida's arrest-stage cutoff.

Why the others miss

The traps in the wrong answers

B. A BAL between .02 and .05 confirmed at the roadside.

The .02 window applies to zero-tolerance suspensions for drivers under 21, not the adult arrest threshold. Applies the under-21 zero-tolerance range to adults and treats the youth threshold as the general one.

C. An officer's observation of erratic driving without any chemical test.

The administrative suspension the manual describes is tied to a chemical result or a refusal, not observation alone. Confuses probable cause to stop or arrest with the specific chemical-result trigger the administrative suspension requires.

D. Blowing a .05 or higher on the officer's portable breath device.

A .05 reading falls below the .08 threshold the manual names for administrative suspension at arrest. Carries in the .05 figure some national safety groups recommend as a lower legal limit and treats it as Florida's arrest-stage cutoff.
