Quiet Summer Nights on Two Wheels: Northern Taiwan Launches Cross-Municipal Crackdown on Modified Exhaust Noise

Summer vacation is a long-anticipated break for teenagers and young adults, when many students organize nighttime rides with friends to enjoy open roads and breezy evenings. However, group night rides frequently escalate into spontaneous street racing and excessive exhaust noise that disturbs local residential tranquility.

To address this recurring summer nuisance, the Environmental Protection Department of New Taipei City partnered with Keelung, Taipei, and Taoyuan to launch a regional anti-noise campaign running from July through September. This initiative strengthens multi-agency monitoring and joint law enforcement across northern metropolitan boundaries to restore nighttime peace for urban communities.

According to New Taipei’s Environmental Protection Department, vehicular noise complaints remain persistent across northern Taiwan. While each municipality runs independent roadside inspections, modified motorbikes frequently cross administrative borders within minutes. A coordinated regional defense network is far more effective at intercepting repeat violators.

Through the Keelung-Taipei-New Taipei-Taoyuan Environmental Protection Cooperation Platform, municipal authorities established synchronized checkpoints along border-connecting thoroughfares during critical nighttime rest hours. Environmental officers, police units, and motor vehicle inspection bureaus work in tandem to intercept and penalize offenders.

Officials emphasized that enforcement extends beyond nocturnal roadside stops. During daylight hours, New Taipei deploys automated acoustic camera arrays, conducts emissions inspections on modified vehicles, and executes joint multi-agency audits targeting illicit aftermarket repair shops.

New Taipei has progressively tightened regulations on noisy vehicles:

• Expanded Vehicle Modification Bans: Under the Noise Control Act, New Taipei previously prohibited vehicles with non-certified exhaust pipes from operating between 10:00 PM and 6:00 AM. Violators face fines between NT$3,000 and NT$30,000. Over 450 joint operations have yielded nearly 50,000 citations. The city has recently expanded this restriction to a full 24-hour ban on uncertified modified exhausts.
• Automated Acoustic Camera Enforcement: Since 2021, New Taipei has deployed 170 acoustic camera systems—the largest network in Taiwan. Vehicles exceeding statutory decibel thresholds are automatically flagged, fined between NT$1,800 and NT$3,600, and ordered for reinspection, resulting in nearly 8,500 penalties to date.
• Third-Party Administrative Audits: In collaboration with police, economic development, urban planning, and revenue bureaus, the city has inspected 118 aftermarket motorcycle tuning shops to clamp down on illegal modifications and promote certified replacement parts.
• Daytime Emissions & Decibel Screenings: Agency data reveals that nearly 30% of motorcycles utilizing uncertified exhaust systems also fail mandatory emissions standards. Daytime checkpoints actively target these bikes, issuing fines between NT$1,500 and NT$6,000 alongside rectification orders.

Despite these aggressive local efforts, local officials noted that completely resolving the problem requires federal action. Current central testing protocols often fail to mirror real-world driving conditions, and statutory sound thresholds do not always align with public acoustic perception. Furthermore, national regulations still lack upstream bans on the manufacture and retail sale of non-compliant exhaust parts. New Taipei has repeatedly petitioned central ministries—including the Ministry of Environment, the Ministry of Transportation and Communications, and the Ministry of Economic Affairs—to enact nationwide source controls.

As summer begins, riders are reminded to respect residential communities, keep their machines compliant, and ride responsibly so that summer nights remain safe, enjoyable, and peaceful for everyone.
