What is the legal blood alcohol content (BAC) limit for drivers 21 years of age or older in Florida?

  1. A0.02%
  2. B0.10%
  3. C0.08%
  4. D0.05%
Show answer & explanation

Correct answer: C. 0.08%

In Florida, as in all U.S. states, the legal blood alcohol content (BAC) limit for drivers 21 years of age or older is 0.08%. Driving with a BAC at or above this level is considered driving under the influence (DUI).

Why the other options are wrong

  • A. 0.02% is the 'zero tolerance' limit for drivers under 21 in Florida.
  • B. 0.10% is higher than the legal limit.
  • D. 0.05% is often a level at which impairment can be presumed, but 0.08% is the per se illegal limit.

Legal BAC Limit (21+)

In Florida, it is illegal for drivers 21 years of age or older to operate a motor vehicle with a blood alcohol content (BAC) of 0.08% or higher.

  • 0.08% is the per se legal limit.
  • Applies to drivers 21 and older.
  • Impairment can occur at lower BACs.
  • Penalties for DUI are severe.
