Loud vehicle events drop on Calgary’s 17 Avenue S.W.

Loud vehicle events on Calgary’s 17 Avenue S.W. dropped 25.2 per cent during enforcement hours in August compared with the same period in 2025, the City of Calgary said in results released Oct. 13 for its Operation Silent Night program.

The city calls 17 Avenue S.W. its highest-priority vehicle noise hot spot. It compared data from a noise monitor near Tomkins Park for August 2026 with August 2025.

During enforcement hours, loud vehicle events fell from 357 to 267. Average sound levels in those hours dropped from 71.18 A-weighted decibels to 68.80, a decrease of 2.38 decibels, the city said.

Across the full analysis period, including hours without enforcement, loud vehicle events fell 10.7 per cent, from 801 to 715.

The city said the strongest reductions came while enforcement was active, which it linked to greater driver awareness and a visible officer presence. It also said weather, traffic volumes and special events can affect sound levels.

Insp. Brad Johnson, head of the city’s Traffic Safety Team, said the results show that “when drivers understand the rules and see a visible enforcement presence” the city can make a meaningful difference in reducing excessive vehicle noise.

The city said its citywide noise-monitoring network gives it objective data to identify hot spots, track trends and evaluate initiatives like this one.

The release did not give the exact enforcement dates, the number of officers involved, or how many tickets were issued.
