The Top 5 Reasons Cars Fail A Mobile Roadworthy Logan
Obtaining a mobile roadworthy Logan is a crucial step if you plan to sell, re-register, or transfer ownership of your car. But what happens when your vehicle doesn't pass the inspection? Many car owners are surprised to learn that even minor issues can result in a failed roadworthy test.
We've seen it all. Our experienced inspectors have inspected thousands of vehicles, and some common culprits consistently appear. If you're booking a mobile roadworthy inspection in Logan, here are the top five reasons your car might fail — and how to avoid them.
Worn or Unsafe Tyres
Your tyres are your car's only point of contact with the road, and they're one of the first things our inspectors check. If your tyres are bald, cracked, or unevenly worn, they can seriously compromise your vehicle's safety.
What we check:
· Minimum tread depth (must be at least 1.5mm across the tread)
· Sidewall damage or cracks
· Uneven wear patterns, which can indicate alignment or suspension issues
How to avoid failure:
Regularly inspect your tyres and replace them when they begin to show signs of wear. Don't forget to check your spare tyre as well — it's part of the inspection!
Faulty or Broken Lights
Lights are a crucial part of road safety, as they help you see and be seen. During a car RWC inspection, all exterior lights are checked for operation, clarity, and alignment.
Common failures include:
· Non-functioning brake lights or indicators
· Foggy or cracked headlights
· Poor beam alignment
How to avoid failure:
Test all your lights before the mobile car roadworthy Logan — including indicators, brake lights, headlights (both high and low beams), and number plate lights. Replacing a bulb is a minor fix that can make a big difference.
Brakes Not Up to Standard
Your vehicle's braking system must perform reliably under pressure. A worn-out brake system can lead to serious accidents, which is why it is one of the most critical components to inspect.
What we look for:
· Brake pad thickness
· Functionality of handbrake
· Brake fluid levels
· Signs of leaks or damage
How to avoid failure:
If you hear squealing or grinding or experience a reduction in braking power, have your system checked and repaired before booking a car roadworthy certificate Logan inspection. Regular servicing also helps catch issues early.
Suspension or Steering Issues
A smooth and stable drive depends heavily on your car's suspension and steering systems. Faulty suspension not only affects ride comfort but also impacts control — a safety risk that can't be ignored.
Key issues include:
· Worn or damaged shock absorbers
· Leaking struts
· Loose steering or excessive play
How to avoid failure:
Pay attention to how your car drives. If you experience unusual bouncing, rattling, or instability while turning, have a mechanic inspect it. Any knocking sounds or uneven ride quality should be addressed quickly.
Windscreen & Wipers
Your windscreen and wipers might not seem like a significant concern, but visibility is essential for safe driving. Even minor chips or cracks in the wrong location can lead to a failed inspection.
What's checked:
· Cracks or chips in the driver's field of view
· Wiper condition and effectiveness
· Washer spray function
How to avoid failure:
Repair any windscreen damage before the car roadworthy Logan inspection— small chips can usually be fixed quickly. Replace worn wiper blades and ensure your washer fluid is topped up.
