City of Avoca Announces Next Phase of Noise Camera Program to Curb Excessive Engine Brake Noise
AVOCA, IOWA – The City of Avoca is moving forward with full implementation of its Noise Camera Program to reduce excessive engine brake noise along Highway 59, following the success of a spring pilot project. The initiative is designed to improve quality of life for residents while ensuring fair and effective enforcement of Avoca’s existing engine brake ordinance.
“Jake brakes have been a problem in our community for a long time; it’s exciting to finally have a way to do something about it,” said Mayor Tom Bruck.
The program uses technology from Intelligent Instruments with backend services by Sitestream. Calibrated microphones and high‑resolution cameras detect when noise exceeds ordinance limits, capturing brief audio and video of the vehicle. Trained staff review each case, and verified violations result in citations mailed to the vehicle’s owner with instructions to pay or appeal.
Pilot Results
During the month-long pilot phase this spring, the camera documented 183 violations committed by 83 unique vehicles. About 44% of these violations were attributable to repeat behavior, with nearly one-third were linked to just five individuals. Officials say these findings indicate that enforcement focused on chronic offenders can substantially reduce overall noise levels.
“Quality of life for our residents is the city’s top priority,” said City Administrator Tyler Trout. “Our pilot demonstrated that targeting repeat violators can make a big difference. With this technology, we can more effectively address the few drivers responsible for most of the disruption, improving daily life for the entire community.”
What’s New for Drivers
- Full enforcement operations will begin in October once backend onboarding is complete.
- The program enforces only Avoca’s existing engine brake ordinance; it does not expand enforcement beyond that law.
- Motorists will see “Photo Enforced” signage posted along Highway 59 to notify drivers of automated enforcement tools now in place.
- Enforcement specifically targets semi-trucks and other vehicles using engine compression (“Jake”) brakes.
- Citations will include clear instructions for drivers to either pay the fine or appeal by the listed deadline.
The City emphasizes that the program’s purpose is not only enforcement but also deterrence. By addressing the small number of repeat offenders contributing the majority of excessive noise, Avoca aims to create a quieter and more peaceful environment for residents across the city.
