Roadworthy Certificate in Darwin

A valid roadworthy certificate confirms that your vehicle meets legal safety standards — a requirement for registration, sale, or re-registration across the Northern Territory. At Cadillac Transport Repairs, we conduct detailed inspections that assess key components such as brakes, steering, suspension, lights, tyres, chassis, and windscreen integrity. Our inspections are designed to meet NT road transport regulations and deliver an unbiased, compliance-focused outcome.

Every check is completed by an authorised vehicle inspector at our fully equipped workshop in Winnellie, using reliable, industry-grade assessment tools. We assess heavy vehicles, trailers, and vehicles, ensuring only roadworthy vehicles receive certification. If issues are found, we provide a detailed report outlining what repairs are required to meet compliance.

Our roadworthy inspections follow a step-by-step protocol developed to cover all legally required safety systems. This includes operational checks of braking performance, suspension stability, exhaust condition, body integrity, and visibility features. Every component is assessed in its actual working state, not just for appearance or wear.



If the vehicle meets all criteria, a roadworthy certificate is issued immediately. If it fails, we provide a clear, itemised list of non-compliant areas. Our technicians can also carry out any required repairs in-house, ensuring a seamless reinspection process without needing to coordinate external service providers. We don’t over-service or under-assess — just accurate inspections backed by experienced heavy vehicle professionals.
