Fla. R. Traf. Ct. 6.360

(a) Procedure. When an act is required or allowed to be

done at or within a specified time pursuant to either a court order

or these rules, the official, for good cause shown, may, at any time:

(1) order the period enlarged if the request is made

before the expiration of the period originally prescribed or as

extended by a previous order; or

(2) on motion made after the expiration of the specified

period, permit the act to be done when the failure to act was the

result of excusable neglect.

However, except as provided by statute or elsewhere in these rules,

the official may not extend the time for making a motion for a new

hearing, or for taking an appeal.

(b) Withheld Adjudications. When a defendant elects to

exercise the option of receiving a withheld adjudication pursuant to

section 318.14(9) or (10), Florida Statutes, the clerk shall allow the

defendant such additional time, not exceeding 60 days, as may be

reasonably necessary to fulfill the statutory requirements. If the

defendant has not been able to comply with the statutory

requirements within 60 days, the court, for good cause shown, may

extend the time necessary for the defendant to comply.
