Roadworthy Certificates in North Lakes

A Certificate of Inspection (COI) is a more detailed and ongoing inspection requirement for certain commercial vehicles in Queensland. It is typically required for taxis, rideshare vehicles, buses, and heavy vehicles to ensure they remain safe and compliant while in active service.

An RWC inspection checks the key safety components of a vehicle, including:

• Tyres (tread depth and condition)
• Brakes (pads, discs, hydraulics)
• Steering system
• Suspension components
• Windscreen and windows
• Windscreen wipers and washers
• Lights and indicators
• Wheels and rims
• Seatbelts and restraints
• Vehicle structure for rust or damage
• Fluid leaks that may affect safety

A COI inspection is more comprehensive and focuses on ongoing road safety compliance for commercial vehicles. It typically includes:

• Brake performance and wear
• Steering and suspension systems
• Tyre condition and tread depth
• Lights, reflectors, and electrical systems
• Windscreen and visibility
• Seatbelts and passenger safety equipment
• Body integrity and structural condition
• Undercarriage condition and corrosion
• Engine and driveline safety
• Oil, fuel, coolant, and other fluid leaks
• Compliance with commercial vehicle safety standards

COI inspection intervals depend on the type of vehicle and its use. Commercial passenger vehicles and heavy vehicles are typically required to undergo inspections at regular intervals set by Queensland Transport regulations, often every 6–12 months.

Most Roadworthy Certificate inspections can be completed within a short time depending on the condition of the vehicle. If no issues are found, the certificate can often be issued the same day.

A COI inspection generally takes longer than a standard RWC due to its detailed nature. The time required depends on the vehicle type, condition, and compliance requirements.

In Queensland, a Safety Certificate is generally valid for 2 months or 2,000 km (whichever comes first) for private vehicle sales or transfers.

If a vehicle fails inspection, a report will be provided outlining the required repairs. Once repairs are completed, the vehicle must be re-inspected before certification can be issued.

Yes. Required repairs can often be completed on-site before re-inspection, helping streamline the certification process and reduce downtime.

Common failure reasons include:

• Worn tyres
• Brake wear or failure
• Faulty lights or indicators
• Windscreen damage
• Suspension wear
• Steering issues
• Oil or fluid leaks
• Excessive rust or structural damage

In Queensland, most registered vehicles require a valid Roadworthy Certificate to be legally sold or transferred. Some exemptions may apply depending on the vehicle type or registration status.

A COI is typically required for:

• Taxis and rideshare vehicles
• Buses and passenger transport vehicles
• Heavy vehicles
• Certain commercial fleets
• Vehicles operating under commercial accreditation schemes

A COI is designed for vehicles that carry passengers or operate commercially, meaning they are on the road more frequently and must meet higher ongoing safety standards compared to private vehicles.
