Bylaw officers will deploy their new Noise Snares starting Wednesday, June 20th.

The mobile device acts like a radar gun which officers use in unmarked vehicles.

They're looking for vehicles emitting noise that measures over 96 decibels.

"The limit is 96 decibels and there is no reason a well-maintained, street legal vehicle should register that loud or higher." Says Bill Bruce, Director of Animal & Bylaw Services.

Council approved the addition of the excessive noise provision to Calgary's Traffic Bylaw last year.

Any vehicle caught emitting noise over 96 decibels will be subject to a $200 fine once the one month warning period expires.

Over the course of two open houses in May, 469 motorists tested their vehicles against the Noise Snare with 219, or 47%, registering 96 decibels or more on their first pass by the device.

Alderman John Mar who represents Ward 8 spearheaded the addition of the excessive vehicle noise provision to the Traffic Bylaw. "The Noise Snare gives us another tool for authorities to utilize in enforcing our existing Bylaw and provides definitive proof of violations," said Alderman Mar. "And the fact it can be easily transported to areas of complaint is a huge benefit. I'm very excited about this."

For the first month of deployment, warning notices will be issued by Bylaw officers. After the warning period has ended, violation tickets will be personally served to the registered owner of the offending vehicle.

Violators will not be pulled over at the time of the offence.
