Florida speed limit laws set a default cap of 30 mph in business and residential districts and 55 mph everywhere else when no sign is posted, with the Florida Department of Transportation authorized to raise limits up to 70 mph on interstates. Get caught going over and the consequences scale with how far over you were: a written warning for 1–5 mph, civil fines and license points through the mid-range, and criminal charges with possible jail time once you hit 50 mph over the limit or 100 mph in a way that endangers others.
Default Limits When No Sign Is Posted
Florida Statute § 316.183 sets two statewide defaults that apply automatically wherever a specific limit hasn’t been posted:
- 30 mph in any business or residential district
- 55 mph on all other roads
Counties and cities can push the residential default down to 20 or 25 mph on local roads after a traffic study shows the reduced limit is reasonable.1Florida Senate. Florida Code 316.183 – Unlawful Speed That’s why the sign in a quiet subdivision often reads 25 even though state default would allow 30.
Maximum Posted Limits
Under § 316.187, FDOT can raise limits on specific corridors after an engineering and traffic study. The ceilings are:
- 70 mph on limited-access highways (interstates and similar controlled-access roads)
- 65 mph on four-lane divided highways outside urban areas with populations of 5,000 or more
- 60 mph on other roads under FDOT authority
Those are maximums, not promises. FDOT can post lower where conditions call for it, and 70 mph is the hard cap: no road in Florida is legally posted above it, including turnpikes and toll roads.2The Florida Legislature. Florida Code 316.187 – Establishment of State Speed Zones
School Zones and Construction Zones
School Zones
School zones have the lowest limits you’ll find on Florida roads. Section 316.1895 requires the limit to fall between 15 and 20 mph in urbanized areas, and local governments can set it even lower through local regulation.3The Florida Legislature. Florida Code 316.1895 – Establishment of School Speed Zones, Enforcement; Designation Many zones use flashing beacons tied to the school day. Speeding in an active school zone doubles the base fine.
Construction Zones
In an active work zone, the base speeding fine doubles under § 318.18 when two things are true at once: construction workers are present on or next to the road, and posted signs warn that fines are doubled.4The Florida Legislature. Florida Code 318.18 – Amount of Penalties If the crew has gone home for the night, the doubling doesn’t apply even if the reduced work-zone limit itself is still in effect.
What a Speeding Ticket Actually Costs
The “base fine” in the statute is only part of what you pay. Under § 318.18, base fines run:
- 1–5 mph over: written warning, no fine
- 6–9 mph over: $25
- 10–14 mph over: $100
- 15–19 mph over: $150
- 20–29 mph over: $175
- 30 mph or more over: $250
Mandatory state surcharges add roughly $63 to every moving violation, and some counties tack on local surcharges of up to $45 more.4The Florida Legislature. Florida Code 318.18 – Amount of Penalties After surcharges, a 6–9 mph ticket runs around $88 before local add-ons, and a 30-plus ticket can reach $313 or more before any doubling.
A second conviction for 30 mph or more over within 12 months automatically doubles the base fine, and school-zone and work-zone doubling stacks on top of the regular schedule.4The Florida Legislature. Florida Code 318.18 – Amount of Penalties
Points on Your License
Every speeding conviction adds points to your record under § 322.27:
- 15 mph or less over: 3 points
- More than 15 mph over: 4 points
School-zone speed camera violations don’t carry points.5Florida Senate. Florida Code 322.27 – Authority of Department to Suspend or Revoke License
Hit the following thresholds and the state suspends your license automatically:
- 12 points in 12 months: 30-day suspension
- 18 points in 18 months: 3-month suspension
- 24 points in 36 months: 1-year suspension
Those windows fill up faster than drivers expect. Two 4-point tickets in a year plus one more moving violation puts you at the first threshold.6Florida Department of Highway Safety and Motor Vehicles. Points and Point Suspensions
Keeping Points Off With Traffic School
Most Florida drivers can elect a basic driver improvement course to keep points off their record. You have 30 days from the citation date to make the election, pay the fine, and notify the court. Miss that window and points are assessed automatically.7Florida Department of Highway Safety and Motor Vehicles. Driver Improvement Schools
Two limits apply. You can use the option once every 12 months and no more than eight times in your lifetime. Commercial driver license holders can’t use it at all. If you finish the course on time, the points stay off, though the conviction itself still shows on your record.
When Speeding Becomes a Crime
Florida treats extreme speed as a separate criminal offense under § 316.1922. You cross the line two ways: driving 50 mph or more over the posted limit, or driving 100 mph or more in a manner that threatens the safety of others.8Florida Senate. Florida Code 316.1922 – Dangerous Excessive Speeding
A first conviction carries up to 30 days in jail, a $500 fine, or both. A second conviction within five years raises the ceiling to 90 days in jail, a $1,000 fine, and a mandatory license revocation of 180 days to one year.8Florida Senate. Florida Code 316.1922 – Dangerous Excessive Speeding These are criminal charges requiring a court appearance, and a conviction creates a criminal record, not just a traffic record.
Street Racing Is a Separate Offense
Racing on public roads falls under its own statute, § 316.191, covering drag racing, organized speed competitions, street takeovers, and stunt driving. A first offense is a first-degree misdemeanor carrying a fine of $500 to $2,000 and a one-year license revocation.9The Florida Legislature. Florida Code 316.191 – Racing on Highways, Street Takeovers, and Stunt Driving
Repeats escalate fast. A second conviction within one year becomes a third-degree felony with a minimum $2,500 fine and two-year revocation. A third or subsequent conviction within five years is a second-degree felony with fines up to $7,500 and a four-year revocation.9The Florida Legislature. Florida Code 316.191 – Racing on Highways, Street Takeovers, and Stunt Driving You don’t need to be driving to be charged. Coordinating a race, collecting entry fees, or riding as a knowing passenger all violate the statute.
If You Live Out of State
A Florida speeding conviction follows you home. Florida belongs to the Driver License Compact, under which member states share traffic violation information and the home state treats the out-of-state conviction as if it occurred locally, applying its own point system and suspension rules.10CSG National Center for Interstate Compacts. Driver License Compact Ignoring a Florida ticket because you live elsewhere is one of the quicker paths to a suspension you weren’t expecting.
