The most dangerous roads in Miami-Dade County are the corridors on the county’s own High Injury Network, a short list of streets where a large share of deadly and serious crashes happen. The county says 25% of crashes occur on less than 1% of its roads, and it lists streets such as NW 17th Avenue, NW 7th Street and Ives Dairy Road in that network (Miami-Dade County, 2024; Miami-Dade TPO, 2025).
Redondo Law compiled this page from public data published by Miami-Dade County, the State of Florida and national safety groups. Every number below comes from a published source, and each source is listed at the bottom. We do not rank single intersections, because the public data does not support that kind of list.
Miami-Dade by the numbers
Miami-Dade is Florida’s most populous county, with about 2.71 million people (Miami-Dade County, 2024). It has more traffic deaths than any other county in the state. Here are the key figures, with the years each one covers.
| What was measured | Number | Years | Source |
|---|---|---|---|
| People killed in Miami-Dade traffic crashes | 1,593 | 2018-2022 | Miami-Dade County |
| Miami-Dade’s share of Florida traffic deaths | 9% of 3,536 | 2022 | Miami-Dade County |
| Fatal crashes in Miami-Dade (most of any Florida county) | 287 | 2024 | FLHSMV, via WKMG |
| People killed or seriously injured on Miami-Dade roads | 1,655 | 2023 | County data, via NBC6 |
| Share of those that involved a bicyclist, motorcyclist or pedestrian | 44% | 2023 | County data, via NBC6 |
| Average motorcycle deaths per year in Miami-Dade | About 59 | 2021-2025 | Ride Smart Florida |
| Pedestrians killed in the Miami-Fort Lauderdale-West Palm Beach metro | 1,062 | 2020-2024 | Smart Growth America |
| Reportable boating accidents in Miami-Dade (most in Florida) | 75 | 2024 | FWC, via NBC6 |
The county says there are close to 300 deaths on Miami-Dade roads each year, and thousands more people are badly hurt (Miami-Dade County, Vision Zero). One note on the 287 figure: it counts fatal crashes, not people. Measured per resident, Miami-Dade’s rate was 1.03 fatal crashes per 10,000 people in 2024, lower than many rural counties (WKMG, 2025). The large total reflects how many people live and drive here.
Where serious crashes happened in 2023
NBC6 used the county’s Vision Zero crash map to count deadly and serious-injury crashes by area in 2023 (NBC6, 2025):
- Unincorporated Miami-Dade: 659 crashes, 771 people killed or seriously injured
- City of Miami: 257 crashes, 292 people
- Hialeah: 107 crashes, 122 people
- Miami Gardens: 93 crashes, 117 people
- Coral Gables: 57 crashes, 63 people
- Miami Beach: 59 crashes, 61 people
Roads on the county’s High Injury Network
The High Injury Network is the county’s map of the corridors with the most deadly and serious crashes. To build it, the county looked at 7,314 fatal and serious-injury crashes on all roads from 2018 to 2022. Of those, 2,505 were on county and city roads. Just 40 corridors accounted for about 31% of those 2,505 crashes, on a tiny share of county and city road miles (Miami-Dade DTPW, 2023). The county’s network leaves out state roads, which the Florida Department of Transportation (FDOT) runs.
A 2025 Miami-Dade TPO study, citing the county’s 2024 Vision Zero Action Plan, names major intersections along these streets as part of Miami-Dade’s High Injury Network (Miami-Dade TPO, 2025):
- NW 3rd Avenue
- NW 7th Street
- NW 14th Street
- Dade Boulevard
- NW 17th Avenue
- Ives Dairy Road
NBC6 reported that a stretch of NW 17th Avenue, about half a mile south of NW 127th Street, is on the county’s high injury network and is a county priority. NBC6 also named intersections where serious crashes happened in 2023. At NW 17th Avenue and NW 127th Street, it reported two fatal crashes and two serious-injury crashes that year. It reported two fatal crashes at SW 88th Street and SW 112th Avenue, and three serious-injury crashes at SW 40th Street and SW 42nd Avenue in Coral Gables (NBC6, 2025). These are examples from news reporting, not a ranking.
The county also keeps a list of priority intersections. Those are places picked for planned safety projects. They are not a ranking of the most dangerous spots.
State roads are part of the picture
Because the county network leaves out state roads, some busy corridors are not on it. One example is U.S. 1. A ConsumerAffairs review of federal crash data (NHTSA’s Fatality Analysis Reporting System) counted 49 deaths on U.S. 1 in Miami-Dade from 2020 to 2022 (ConsumerAffairs, 2024). NBC6 also noted that some of the intersections it named sit on state roads, so FDOT, not the county, controls the fixes there (NBC6, 2025).
Why are these roads risky? The county points to “distracted or impaired driving, speeding, or roadway designs that prioritize vehicular traffic” (Miami-Dade County, 2024). Its plan calls for working toward a 35 mph limit, down from 45 mph, on suitable major roads. The county’s network also gives extra weight to crashes that hurt people walking and biking.
Pedestrians and cyclists
People on foot and on bikes face the greatest danger. In Smart Growth America’s 2026 Dangerous by Design report, the Miami-Fort Lauderdale-West Palm Beach metro area ranked 17th of 101 metro areas for pedestrian danger. It recorded 1,062 pedestrian deaths from 2020 to 2024, up from 945 in 2015 to 2019. That is 3.4 deaths per 100,000 residents per year. Florida ranked 5th of 50 states, with 3,726 pedestrian deaths in those five years (Smart Growth America, 2026).
Crashes are rising too. Countywide, bicycle crashes rose 32% from 2020 to 2024, and pedestrian crashes rose more than 50% (Miami-Dade TPO, 2025). The county reported a nearly 40% rise in pedestrian and cyclist crashes from 2012 to 2022 (Miami-Dade County, 2023). Statewide, 791 pedestrians and 234 bicyclists died in crashes in 2023 (FLHSMV, 2023).
Motorcycles
Miami-Dade averaged about 59 motorcycle deaths a year from 2021 to 2025, the highest of any Florida county, according to Ride Smart Florida (Ride Smart Florida, 2025). Statewide, 621 people died in motorcycle crashes in 2023 (FLHSMV, 2023). Riders have no steel frame or airbags around them. A crash that would dent a car can be life-changing for a rider.
When deadly crashes happen
We did not find a public, county-level breakdown by time of day. Florida’s statewide numbers show a clear pattern, though. In 2023, the most traffic deaths happened on Saturday (603), Sunday (563) and Friday (508). Monday through Thursday each had between 418 and 438 (FLHSMV, 2023).
Darkness matters too. In 2023, 1,875 of Florida’s 3,375 traffic deaths happened after dark, on either lit or unlit roads. Another 1,292 happened in daylight (FLHSMV, 2023).
On the water: Miami-Dade led Florida in boating accidents
Miami-Dade had more reportable boating accidents in 2024 than any other Florida county, according to Florida Fish and Wildlife Conservation Commission (FWC) data reported by NBC6 and News4JAX. Statewide, Florida had 685 reportable accidents and 81 deaths in 2024. Hitting a fixed object was the most common type of accident, at 31%. And 65% of operators in fatal accidents had no formal boating training (FWC, 2025). If you were hurt on the water, see our boat accident page.
What makes a road dangerous
Most dangerous roads share a few traits. None of them are a mystery.
- Speed. The faster a car goes, the less time a driver has to stop and the harder the hit. This is why the county wants lower limits on many major roads.
- Wide, multi-lane roads. Wide roads invite fast driving. They also mean long crossings for people on foot.
- Turning traffic. Drivers turning across lanes must watch cars, bikes and people in the crosswalk at the same time. Mistakes happen here.
- Many driveways and side streets. Every entrance to a shopping plaza or gas station is another spot where cars cross paths.
- People walking and biking next to fast traffic. Long gaps between crosswalks push people to cross mid-block.
- Darkness. Poor lighting makes people on foot and on bikes hard to see.
How to stay safer on these roads
- Slow down, even when traffic around you is speeding.
- Put the phone away. Set your GPS and music before you drive.
- Never drive after drinking. Use a rideshare or a sober driver.
- Look twice for people walking and biking before you turn.
- If you walk, cross at a signal or marked crosswalk, and wait for the walk sign.
- Wear light or reflective clothing at night, and use lights on your bike.
- On a motorcycle, wear a helmet and gear, and assume drivers cannot see you.
- Leave extra space on weekend nights, when deadly crashes are most common.

Sources and methodology
We used only aggregate, public data. We did not use individual crash reports. Under Florida law, crash reports are confidential for 60 days after they are filed (FLHSMV). We did not rank intersections ourselves. Where a number comes from a news report, we name the outlet. Sources cover different years, so compare figures with care. The county’s priority intersections are planned safety projects, not a ranking. We plan to update this page as new data comes out.
