For a second DUI conviction in Florida, what is the minimum required period for an ignition interlock device?
-
A.
At least one continuous year. Correct
-
B.
Only when a judge specifically orders one.
-
C.
Six continuous months.
-
D.
At least two continuous years.
The answer is "At least one continuous year."
The manual sets the second-DUI ignition interlock at one continuous year. Choice C reaches for the six-month figure the manual attaches to a first DUI only when the BAL is .15 or higher or a minor was in the vehicle, then imports it as if it were the second-conviction baseline.
The traps in the wrong answers
B. Only when a judge specifically orders one.
The interlock is mandatory on a second conviction, not discretionary. This answer carries the 'if court ordered' phrasing from the first-DUI block into the second-DUI block, where the requirement is now automatic.
C. Six continuous months.
Six months is the interlock period the manual lists for a first DUI only when a minor was in the vehicle or the BAL was .15 or higher, not the second-conviction minimum. This answer pulls the enhanced first-offense figure forward and treats it as the baseline for the second conviction.
D. At least two continuous years.
Two continuous years is the interlock minimum the manual lists for a third DUI conviction, one row below the second on the same penalty table. This answer slides one row down the penalty table and reads the third-offense figure as the second-offense one.
