by Tallahassee, Florida — A sweeping transportation bill moving through the Florida Legislature could soon change how vehicle noise violations are enforced across the state. Lawmakers in the Florida House recently approved a measure that would ban intentionally revving engines to create excessive noise, potentially giving police broader authority to issue citations.
The legislation, known as HB 543, passed the Florida House on March 5 by a vote of 107 to 1. The bill was sponsored by Republican Rep. Fiona McFarland of Sarasota, but it has not yet become law.
Before the rule can take effect, the Florida Senate must approve the measure and Gov. Ron DeSantis must sign it into law. If that happens, the new engine noise rule would begin July 1, 2026.
“The proposal would make it illegal for drivers to intentionally rev their engines or accelerate in a way that creates excessive or unusual noise.”
Proposed law would eliminate current decibel limits
Florida’s current law regulates vehicle noise using specific decibel thresholds. Under existing rules, vehicles cannot exceed 72 decibels when traveling under 35 mph and 79 decibels on faster roads.
HB 543 would eliminate those numerical limits entirely.
Instead of measuring sound levels, the new rule would allow officers to cite drivers who intentionally rev engines or accelerate in a way that produces “excessive or unusual” vehicle noise.
The bill still requires vehicles to maintain properly functioning exhaust systems, but enforcement would shift away from sound meters toward officer observation.
Lawmakers say current rules are difficult to enforce
Supporters of the change say the existing decibel-based law has proven difficult for officers to enforce in real-world situations.
Enforcement requires specialized sound meters, controlled testing conditions, and training that many departments do not have.
A 2023 state review revealed that 79% of surveyed law enforcement agencies reported having no training to enforce exhaust noise laws.
At the same time, complaints and citations related to vehicle noise have been rising. According to the report, exhaust noise citations increased from about 857 in 2017–2018 to roughly 3,018 in 2021–2022.
Supporters say the new approach will allow officers to respond more effectively to complaints.
Officers would rely on observation rather than measurements
Under the proposed law, police would determine whether noise violations occurred based on direct observation rather than decibel readings.
Evidence supporting a citation could include:
- Officer observations
- Body camera audio recordings
- Witness statements
This approach is similar to how Florida currently handles loud music from vehicles, where officers can issue citations if music is clearly audible beyond a certain distance.
“Supporters argue that allowing officers to judge excessive noise directly is more practical than relying on equipment many departments do not have.”

Motorcycles and mopeds would be exempt
The legislation includes an exemption for motorcycles and mopeds.
Riders would not be subject to the new subjective engine-revving rule as long as their vehicles comply with federal noise standards set by the Environmental Protection Agency (EPA).
Currently, the state noise limit for motorcycles is roughly 80 decibels.
The exemption means motorcycle riders would still follow federal noise guidelines but would not face citations under the new revving rule.
Similar laws have faced legal challenges before
Florida has previously attempted to enforce noise violations using subjective standards.
In 2012, the Florida Supreme Court struck down a “plainly audible” loud music law, ruling that it was too vague and could lead to inconsistent enforcement.
Lawmakers later revised the rule, and a new version took effect in July 2022, banning music that can be heard 25 feet away from a vehicle.
Because the proposed engine noise rule lacks a specific decibel threshold, some legal observers say it could face similar legal scrutiny.
Critics argue that without a clear measurement, drivers may have an easier time challenging citations in court.
Transportation bill includes several other changes
The proposed engine noise rule is only one part of the 68-page transportation bill, which covers a wide range of policy changes.
Other provisions in the bill include:
- Increasing yellow light duration by 0.4 seconds at intersections with red-light cameras
- Clarifying that license plate frames are legal as long as they do not block numbers or registration stickers
- Allowing local governments more flexibility to lower speed limits in residential areas
- Addressing digital driver’s license privacy protections
- Expanding rules for school zone speed cameras
- Updating regulations for golf carts and disabled parking permits
Senate version still under consideration
The Florida Senate is reviewing its own version of the legislation.
Republican Sen. Nick DiCeglie of St. Petersburg filed a companion bill, SB 1274, which has already cleared its first committee. Another related measure, SB 1080, also addresses parts of the transportation package.
Senate lawmakers have introduced amendments that could reshape the final version of the bill, meaning some provisions may change before final approval.
Current noise laws remain in effect for now
Until a new law is officially passed and signed, Florida’s existing vehicle noise regulations remain in place under Florida Statute 316.293.
Drivers can still receive citations for excessively loud or modified exhaust systems. These violations are typically classified as nonmoving traffic infractions with fines around $116.
Vehicles with modified exhaust systems face additional penalties, including $200 for a first offense and $500 for repeat violations.
“For now, Florida drivers must continue following the existing decibel-based noise rules until lawmakers finalize any changes.”
The bill still faces several steps before becoming law, and its final version could change during negotiations between the House and Senate.
