Florida Speed Limits: The Complete Guide
5 min read
Florida sets its speed limits by statute, which means the limits are the same across the state unless a posted sign says otherwise. Knowing the default limits and the rules for adjusting your speed is one of the most heavily tested areas of the Class E exam.
Florida’s Statutory Speed Limits
Florida law establishes standard speed limits for different types of roadways. These apply everywhere in the state unless a sign posts a different limit.
| Roadway Type | Speed Limit |
|---|---|
| School zones (when children are present) | 20 mph |
| Municipal, business, or residential areas | 30 mph |
| Streets and highways | 55 mph |
| Limited access highways (interstates) | 70 mph |
Adjusting Your Speed
The posted limit is the maximum legal speed under ideal conditions, not a target. Florida law requires you to drive at a speed that is reasonable and prudent for the current conditions. In rain, fog, heavy traffic, or on wet pavement, you must slow down even if you are below the posted limit.
You must also stop for a school bus displaying its stop signal. On a two-way street or highway, all drivers moving in either direction must stop for a stopped school bus that is picking up or dropping off children, and remain stopped until the stop signal is withdrawn and all children are clear of the roadway. The only exception is on a divided highway with a raised barrier or unpaved median at least five feet wide, where oncoming traffic proceeds with caution.
Speeding fines are doubled in school zones and construction zones, so obey the posted limits there carefully.
The 4-Second Following Rule
Florida recommends maintaining at least a 4-second following distance behind the vehicle ahead of you under normal conditions. Pick a fixed object ahead, such as a sign or overpass, and count the seconds between when the vehicle in front passes it and when you do. If you reach the object in fewer than 4 seconds, you are following too closely.
Increase your following distance in poor weather, at night, when driving a heavy vehicle, or when being tailgated. The 4-second rule is tested frequently, and the number 4 is the one to remember.
Slow-Moving Vehicles
Driving too slowly is also against Florida law. You must not drive so slowly that you block or delay traffic moving at normal, safe speeds. When driving slower than the flow of traffic, keep right so others may safely pass.
On limited access highways where the posted speed limit is 70 mph, the minimum speed limit is 50 mph. Driving below the minimum can be just as much a violation as speeding.
