Experts warn motorcycle noise poses growing public health risk

Noise pollution from motorcycles — especially those equipped with illegal or modified exhaust systems — is emerging as a serious public health threat, according to experts and road safety organizations in Greece.

According to Despina Konti's article published in Kathimerini specialists warn that excessive urban noise, often dismissed as a nuisance, can have long-term health consequences ranging from hearing loss and stress to cardiovascular problems and sleep disorders.

“This is a silent killer,” said Aris Zografos, president of the Panhellenic Association of Driving Instructors. “It’s particularly dangerous for people living near major roads, where some motorcycles can reach up to 120 decibels — the threshold of physical pain.”

Illegal Modifications on the Rise

According to Petros Andrianakis of the Greek Motorcycle Federation (MOTOE), a growing number of riders are illegally replacing factory exhausts with racing-grade models, often installed on scooters with engines over 500cc. These aftermarket parts, while intended for closed-track use, are widely available on the open market and frequently exceed legal noise limits.

Health and Quality of Life Concerns

Urban transport expert Eftychia Nathanail stressed that urban noise pollution is directly linked to quality of life. Even long-term exposure to moderate levels — such as 55 decibels — can lead to significant health issues. European studies, she added, reveal that motorcycles create over ten times more noise disturbance than cars over the same distance.

Stricter Penalties Under New Traffic Code

To address the issue, Greece’s updated Traffic Code introduces a series of tougher penalties: €350 fines for noise or pollution violations, 70-day license suspensions, and 30-day plate confiscation.

Additionally, vehicles found without legal mufflers now face a €150 fine, as such modifications are deemed antisocial behavior.

Enforcement Still a Challenge

Despite increased roadside checks by the Traffic Police and inspections at KTEO (Vehicle Inspection Centers), enforcement remains difficult. Experts note that many riders reinstall illegal exhausts after passing inspections.

A Path to Quieter Cities

Experts advocate for lower urban speed limits — particularly the implementation of 30 km/h zones — which could reduce traffic noise by up to 8 decibels. Combined with better enforcement and public awareness, such measures could pave the way toward quieter, healthier, and more livable cities.
