A 54-year-old man is facing a felony charge after deputies say he caused a crash near a busy West Kendall intersection Monday morning, then blocked the other driver's car and revealed a handgun during the confrontation. Carlos Mario Acosta was arrested on a charge of aggravated assault with a firearm following the encounter, which unfolded around 9:10 a.m. on Southwest 137th Avenue near Southwest 120th Street.
According to the arrest report issued by the Miami-Dade Sheriff's Office, the victim was traveling north on Southwest 137th Avenue and attempting to change lanes when Acosta drove extremely close to the rear driver's side of the victim's vehicle. As reported by WPLG Local 10, Acosta then sideswiped the other car, and when the traffic light turned green, he attempted to pass the victim before positioning his own vehicle in front of the victim's car to prevent him from leaving.
Driver Says He Wasn't Sure He'd Even Been Hit
The victim's vehicle ended up stopped at an angle in front of Acosta's after the maneuver, the outlet's report notes. The victim told deputies he was unsure whether his vehicle had even been involved in the collision, but he approached Acosta's vehicle after the crash, per the arrest report.
That's when, according to the account Acosta gave investigators, he returned to his own vehicle, revealed a handgun while standing in front of the victim's car, and gripped the weapon over his shirt. Acosta also pulled the door handle of the victim's vehicle during the standoff, the same report states, before eventually putting the gun back inside his own car.
Conflicting Accounts of Intent
Acosta told deputies he had his gun ready because he did not know the victim's intentions after the crash, an explanation that frames the episode as a defensive reaction to an uncertain situation. The account attributed to the victim, however, describes Acosta as the one who blocked the car in and pulled the door handle before showing the weapon — a sequence that, if accurate, would undercut a self-defense framing under Florida's Stand Your Ground law. Per Goldman Wetzel, that statute allows the display or use of force only when someone reasonably believes it necessary to defend against imminent unlawful force, and courts have held that brandishing a weapon during a mutual traffic confrontation typically does not meet that bar without a reasonable fear of imminent harm.
Acosta agreed to speak with investigators after being read his Miranda rights, the report notes. He was transported to Turner Guilford Knight Correctional Center, a Miami-Dade County intake and pre-trial detention facility described by Miami-Dade County as its primary 1,300-bed hub for processing adult felony arrests. As of Tuesday afternoon, Acosta remained held there on a $3,000 bond, and his vehicle was turned over to Yezenia Acosta.
What Acosta Faces Under Florida Law
Aggravated assault is a third-degree felony under Florida Statute § 784.021, carrying up to five years in state prison, five years of probation, and a $5,000 fine. Because the charge involves a firearm, Florida's 10-20-Life sentencing statute adds a mandatory minimum of three years in state prison if Acosta is convicted, a provision that leaves judges little room to offer straight probation in qualifying firearm cases.
The intersection where the confrontation happened sits in West Kendall near the London Square commercial center and Miami Executive Airport, a stretch that functions as a heavily traveled north-south commuter corridor in unincorporated Miami-Dade County. Southwest 120th Street, which crosses it, connects nearby residential subdivisions to the Florida Turnpike, and the area has seen its share of gridlock before — a second-alarm brush fire near the same intersection in May 2026 triggered road closures and severe delays.
Part of a Wider Pattern
Acosta's arrest lands amid a documented rise in armed road rage encounters across Florida. Fatal road rage crashes statewide surged 200% between 2023 and 2024, climbing from 12 deaths to 36, according to an analysis of federal traffic data reported by WTSP. Nationally, roughly 37% of aggressive driving and road rage confrontations involve a firearm, per research compiled by The Zebra.
Hoodline has covered several similar incidents in Miami-Dade this year, including a road rage shooting caught on camera and an arrest tied to a gun threat over a blown kiss on Southwest 107th Avenue. Acosta's case now joins that growing list as it moves through the Miami-Dade court system.
