</div></div><p></p><h2>Mechanical Issues</h2><p>Driving can be dangerous when your vehicle has hidden faults, such as excessive exhaust smoke or leaks. Carefully inspect your vehicle and book a professional inspection as soon as you spot issues with the following parts:</p><h3>1. Wheels, Tyres &amp; Brakes</h3><p>Wheels, tyres, and brakes are the most common parts with problems. An inspection will highlight signs of excessive wear, tears, or cuts in the tyres, faulty brakes, or damaged wheel bearings, which can affect the grip and reduce power. Grooved or concave brake discs, or leakage in the hydraulic system, can worsen the problem and make driving hazardous.</p><h3>2. Suspension</h3><p>Uneven tyre wear often indicates that a suspension system is not holding the wheels correctly, which leads to premature tyre replacement. Damage to the undercarriage's shock absorbers, kingpins, control arms, anti-roll bars, chassis, leaks, or rust also indicates something's amiss. It can cause your vehicle to become bumpy and drift or pull to one side during turns.</p><h3>3. Steering Systems</h3><p>When the steering feels stiff or unresponsive or makes a grinding or squealing noise, it's time to change it for a seamless driving experience. Excessive vibrations or loose or stiff steering components can make manoeuvring challenging, and the delayed turns can increase the chances of accidents.</p><h3>4. Engine &amp; Transmission</h3><p>Excessive travel and poor maintenance can severely damage the engine's and transmission's health. If you hear odd noises, find leaks or damage in the engine compartment, or if the engine and transmission are no longer securely mounted, you're likely to experience more critical breakdowns. Smokey or burning smells from the engine, jerks in transmission, or damaged wiring are other signs that highlight the poor condition of your vehicle. If left unchecked, these issues could pose a notable danger.</p><h3>5. Horn &amp; Safety Equipment</h3><p>A faulty or broken horn can compromise the safety of other road users. An inconsistent sound, where your horn works intermittently, or a static or hissing noise indicates the system is malfunctioning. Dim or broken headlights or taillights, faulty indicators, and defective seatbelts are concerning signs that your vehicle poses a serious safety hazard.</p><h2>Structural Integrity</h2><p>Safety and reliability depend on the strength of your vehicle's structural integrity. Any compromise to the original equipment or body frame can directly affect the control arms, power steering, wiper blades, and other components, as well as their overall performance.</p><h3>1. Structural &amp; Body Damage</h3><p>The stronger the structure, the better it absorbs the pressure of a sudden collision. To identify structural and body damage, look for signs like uneven tyre wear, cracks and dents, uneven gaps between doors, rust on the bumpers and along the doors and undercarriage, and unusual creaking or rattling sounds. If you notice these signs, schedule a professional inspection and have your vehicle repaired.</p><h3>2. Interior</h3><p>Your vehicle's interior provides safety. Frayed, loose, or broken seatbelt locks indicate that your car may not be suitable for the roads. Other concerning factors are cracked dashboards, broken or non-functioning seats, faulty handbrakes, sticky paddles, loose steering wheels, and worn-out upholstery that traps moisture or mould and weakens the flooring.</p><h2>Electrical and Safety Systems</h2><p>Modern vehicles have advanced electrical and safety features. While some faults are easy to spot, not fixing them early can put your car at risk.</p><h3>1. Lights</h3><p>You should check your lights to determine if your car is fit for driving. Dim, flickering, or non-functional headlights affect visibility and make the vehicle unsafe on the roads, especially at night. Cloudy, foggy, or malfunctioning hazard lights, brake lights, and test indicators also reduce visibility, thus making it harder to see the road. Moreover, check the dashboard lights inside the cabin. If they don't illuminate when the engine starts or stay on, your car is unroadworthy.</p><h3>2. Windscreen &amp; Windows</h3><p>Windshields and windows provide visibility and safety from external components. However, if you find sharp edges, damaged windscreen wipers, spider webs, star breaks, small chips or cracks, fogging, or a hazy appearance, or distorted or wavy glass, your car requires immediate attention. You should also check if the windows are functional. Stuck or nonfunctional windows can affect ventilation and increase safety concerns.</p><h2>Other Factors That Influence Your Roadworthy Certificate</h2><p>Besides the mechanical, structural, electrical, and safety factors, other small details can affect your roadworthy certificate. For example, damaged number plates, an exhaust leak, low oil, coolant, and brake fluid levels, cracked mirrors, dysfunctional wiper blades, and broken seatbelts are enough to warrant a defect notice for your car.</p><h2>Why Driving an Unroadworthy Vehicle Is Dangerous</h2><p>Driving a vehicle without a roadworthy certificate is illegal. Defects such as worn-out suspension, faulty brakes, leaky engines, broken lights, or cracked windshields can be life-threatening for other drivers and passengers, and cause considerable legal and financial inconveniences for you.</p><h3>1. Legal Penalties</h3><p>Driving an unroadworthy, unregistered, or uninsured car in Australia can result in severe <a href="https://www.nsw.gov.au/driving-boating-and-transport/demerits-penalties-and-offences/offences/search-offences-and-penalties" rel="noopener noreferrer nofollow">penalties</a>, including demerit points, licence suspension, vehicle impoundment, or even imprisonment, all depending on the severity of the vehicle's condition.</p><h3>2. Accidents and Injuries</h3><p>Cars with faulty brakes and steering are more likely to crash due to a lack of control, which can cause serious injuries.</p><h3>3. Financial Costs</h3><p>Repairing damaged car parts or paying compensation for the damages caused by your car can be considerably more expensive than regular maintenance expenses.</p><h2>What to Do if Your Vehicle Isn't Roadworthy</h2><p>An unroadworthy vehicle is a liability and requires extensive repairs. However, fixing it early can save you from penalties and legal complexities. Here's what you should do:</p><ul><li><p>Stop driving the car.</p></li><li><p>Contact a licensed vehicle tester for inspection.</p></li><li><p>Check for free play in suspension or steering.</p></li><li><p>Repair the main safety components: brakes, seatbelts, horn, and lights.</p></li><li><p>Arrange a second inspection after the repair to assess the vehicle's condition.</p></li></ul><h2>Conclusion</h2><p>A car requires regular repairs and inspections to remain roadworthy. Ignoring the warning signs will compromise your family's safety, lead to expensive repairs, and increase the likelihood of legal issues. Stay proactive with maintenance and repairs from certified professionals to ensure safety and compliance with legal requirements.</p><p>In the unfortunate event that you are involved in an accident and your vehicle is deemed unroadworthy, you can contract a trusted car replacement service, such as Right2Drive, for a no-cost replacement car, provided you're not at fault. Our service will allow you to continue with your daily activities uninterrupted while your vehicle is under repair or while you wait for the settlement of your claim.
