GEORGE TOWN: Motorcycles fitted with noisy exhaust pipes are forced to face the music at a large-scale road block at the Penang Bridge here today.

The Penang Department of Environment (DoE) issued compounds of RM300 to those with machines fitted with modified exhausts.

The DoE is part of a 100-strong team of various enforcement agencies under the Op Tahun Baru Cina at the bridge today.

As of 10pm, some 20 motorcycles with 'sporty notes' have been slapped with fines.

A team of seven Penang DoE officers armed with sound level meters and other high tech gadgets measured the noise produced by the exhausts.

The enforcement officers take three sound measurements at varying RPMs, and an average number of the three is taken.

If it exceeds 95dBm, a compound will be issued right away under the Environmental Quality (Motor Vehicle Noise) Regulations 1987.

The multi agency operations is expected to be carried out until Feb 25 in view of the upcoming Chinese New Year holidays.
