Seeing a warning light on your dashboard just before a roadworthy inspection can be stressful, especially if you are planning to sell your car, transfer its registration or prepare it for another driver. You may wonder whether a small dashboard symbol will prevent you from receiving a Certificate of Roadworthiness (RWC).
The answer depends on the warning light, the underlying fault and whether the issue affects your vehicle’s safety or compliance with Victorian roadworthiness requirements.
Understanding the relationship between warning lights roadworthy inspection requirements can help you prepare your vehicle, identify potential problems early and avoid unnecessary delays.
For drivers in Campbellfield and surrounding northern Melbourne suburbs, getting a warning light checked before an inspection can provide a clearer picture of the vehicle’s condition. At 3D Auto Mechanic, drivers can access roadworthy inspection services and automotive repairs to help address relevant vehicle issues.
In this guide, we explain which dashboard warning lights deserve attention, how they may affect an RWC result and what you should do before bringing your car in for inspection.
What Is a Roadworthy Inspection in Victoria?
A roadworthy inspection assesses whether a vehicle meets the applicable minimum safety requirements for use on public roads at the time of testing.
In Victoria, a Certificate of Roadworthiness is generally required when selling a vehicle, re-registering certain vehicles or clearing some vehicle defect notices. Specific exemptions and circumstances may apply, so it is worth checking the requirements for your vehicle.
During an inspection, a licensed vehicle tester examines important safety-related components, including:
- Brakes and braking performance
- Wheels and tyres
- Steering and suspension
- Seats and seatbelts
- Headlights, indicators and other required lights
- Windscreen, windows, wipers and washers
- Vehicle structure and relevant body components
- Other applicable safety-related items
Dashboard warning lamps can also be relevant because they may indicate a fault in a system that affects vehicle safety.
According to Transport Victoria’s roadworthiness requirements, warning lamps and other relevant vehicle components are covered by the applicable inspection standards.
It is important to understand that an RWC is not a complete mechanical health assessment. A vehicle can pass a roadworthy inspection and still need servicing or repairs for issues outside the inspection’s scope.
Can a Car With Warning Lights Pass a Roadworthy Inspection?
Yes, a car with a dashboard warning light may still pass a roadworthy inspection, but the result depends on the type of warning and the fault behind it.
Some lights appear temporarily when you start the ignition as part of the vehicle’s normal self-check. Others indicate a problem that needs investigation. Certain warnings may relate to safety-critical systems and can prevent a vehicle from meeting the required standards.
When considering warning lights roadworthy inspection requirements, the key question is not simply whether a symbol is visible. The important question is whether it indicates a fault that makes the vehicle unsafe or otherwise non-compliant.
For example, a low-fuel warning is generally different from a brake-system warning. Similarly, a warning that disappears after the vehicle’s normal start-up checks may be different from a fault indicator that remains illuminated while the engine is running.
The tester must assess the vehicle according to the applicable Victorian standards and the circumstances of the fault.
Important: Do not assume your vehicle will pass just because it drives normally. Some faults are not immediately noticeable while driving, so a warning light should be investigated rather than ignored.
7 Dashboard Warning Lights That May Affect a Roadworthy Inspection
Different warning lights indicate different problems. The following examples explain why certain warnings deserve attention before an RWC appointment.
1. Brake Warning Light
A brake warning light is one of the most important warnings to investigate before an inspection.
Depending on the vehicle, it may indicate that the parking brake is engaged, the brake fluid level is low or there is a fault in the braking system.
If the light stays on after you have released the parking brake, do not assume it is harmless. A braking fault could affect the vehicle’s ability to stop safely.
A tester may identify a roadworthiness issue if the underlying problem affects braking performance or another applicable safety requirement.
If you notice reduced braking performance, a soft brake pedal or unusual braking behaviour, arrange a professional assessment before driving further. If braking ability appears compromised, do not drive the vehicle to the workshop; arrange appropriate recovery.
2. ABS Warning Light
The anti-lock braking system (ABS) helps prevent the wheels from locking under certain braking conditions.
An illuminated ABS warning may indicate a problem with a wheel-speed sensor, wiring, the ABS control unit or another component.
The effect on an inspection depends on the vehicle, the fault and the applicable requirements. A warning related to an essential safety function should not be ignored or treated as an automatic pass.
If your ABS light remains illuminated, have the system assessed before your appointment. A diagnostic scan can help identify stored fault codes and guide further testing.
3. Airbag or SRS Warning Light
The airbag or supplementary restraint system (SRS) warning light indicates that the vehicle’s restraint system may have detected a fault.
Possible causes include wiring problems, sensor faults or issues involving the restraint-system control unit.
Airbags and other restraint components are safety-related. Victorian roadworthiness requirements also address the condition and integrity of relevant safety systems.
An illuminated airbag warning therefore deserves prompt professional attention. The tester will need to assess the vehicle against the applicable requirements rather than relying solely on whether the warning light is present.
Do not attempt to disable the warning or tamper with airbag components to obtain a roadworthy certificate.
4. Check Engine Light
The check engine light, also known as the engine malfunction indicator, can illuminate for various reasons.
Possible causes include:
- Faults involving engine sensors
- Ignition or misfire problems
- Fuel-system issues
- Emissions-control system faults
- Other engine-management problems
Not every check engine light automatically means a vehicle will fail its roadworthy inspection. However, the underlying problem may affect roadworthiness, vehicle compliance or safe operation.
For example, a severe engine misfire or an associated fault that affects the vehicle’s operation should be investigated. A warning that indicates an emissions-control issue also needs to be assessed in the context of the applicable vehicle requirements.
If the light is flashing, the engine is running roughly or the vehicle is losing power, seek prompt professional advice. Avoid continuing to drive if doing so could cause further damage or compromise safety.
A diagnostic assessment can help determine the cause instead of relying on guesswork.
5. Power Steering Warning Light
Some vehicles display an electric power steering (EPS) warning when the system detects a fault.
You may notice that the steering becomes heavier, less responsive or inconsistent.
Steering is a core part of roadworthiness, so any warning accompanied by unusual steering behaviour should be taken seriously.
The inspection outcome will depend on the actual condition of the steering system and whether it meets the relevant safety standards.
If the steering feels difficult to control, do not continue driving simply to reach your RWC appointment. Arrange an appropriate assessment and recovery if necessary.
6. Tyre Pressure Monitoring System (TPMS) Warning
A tyre pressure monitoring system warns the driver when tyre pressure may be too low or when the system detects a problem.
A TPMS warning does not necessarily mean the vehicle will fail an RWC. However, the actual condition of the tyres remains important.
During a roadworthy inspection, the tester checks relevant tyre and wheel requirements, including tyre condition and suitability for road use.
Before your appointment:
- Check the tyre pressures against the manufacturer’s recommendations.
- Inspect the tyres for visible damage.
- Look for excessive or uneven tread wear.
- Have punctures or suspected leaks assessed.
- Check that the tyres meet the applicable requirements.
Correct tyre pressure alone will not resolve a damaged or excessively worn tyre. If the warning remains after the tyres have been checked, have the system assessed as necessary.
7. Battery or Charging System Warning Light
A battery warning light may indicate a problem with the charging system rather than simply an old battery.
Potential causes include an alternator fault, a damaged belt, wiring problems or battery-related issues.
A charging fault can cause the vehicle to lose electrical power or stop operating reliably. The implications for an RWC depend on the underlying fault and its effect on applicable roadworthiness requirements.
If the light appears while driving, or you experience dimming lights, difficulty starting or electrical problems, arrange an assessment.
A mechanic can test the battery and charging system to help identify the cause and determine whether repairs are needed.
Which Warning Lights Are Usually Less Concerning?
Not every dashboard warning indicates a safety-related defect.
Some warnings may be associated with normal vehicle operation or non-safety-related functions. Examples can include a low-fuel warning, a reminder to replace engine oil or a notification that a door is open.
However, the meaning of a symbol can vary between vehicle makes and models.
A maintenance reminder is not necessarily the same as a fault indicator, and a warning that seems minor may sometimes point to a more significant underlying problem.
When assessing warning lights roadworthy inspection concerns, check the owner’s handbook to understand what the symbol means. If you are uncertain, ask a qualified mechanic to investigate it.
The safest approach is to understand the cause rather than assume a warning is irrelevant.
What Should You Do Before Your Roadworthy Inspection?
If a warning light appears before your RWC appointment, taking a few sensible steps can help you avoid unnecessary delays.
Step 1: Identify the Warning Light
Look at the dashboard symbol and check your owner’s handbook. Note whether the light appears when you start the ignition, remains illuminated once the engine is running or appears while driving.
This information can help the mechanic understand the problem.
Step 2: Check for Other Symptoms
Pay attention to anything unusual, including:
- Changes in braking performance
- Heavy or inconsistent steering
- Engine misfires or rough running
- Loss of power
- Unusual noises or smells
- Difficulty starting the vehicle
If you notice a serious safety issue, avoid driving until the vehicle has been assessed.
Step 3: Arrange a Diagnostic Check
A diagnostic scan can help identify fault codes stored by the vehicle’s electronic systems.
However, a scan alone does not always establish the complete cause of a fault. Further inspection or testing may be required.
This step can be especially useful when the warning light remains illuminated but the vehicle appears to drive normally.
Step 4: Complete Necessary Repairs
Once the underlying problem has been identified, discuss the recommended repairs with your mechanic.
Depending on the issue, repairs may involve replacing a faulty sensor, repairing damaged wiring, addressing a braking-system fault or correcting another mechanical or electrical problem.
Step 5: Book Your Roadworthy Inspection
Once relevant faults have been addressed, arrange your inspection with a licensed vehicle tester.
Understanding warning lights roadworthy inspection requirements before your appointment can help you prepare more effectively, but no preliminary check can guarantee a pass.
What Happens If Your Car Fails Because of a Warning Light?
If a vehicle does not meet the applicable roadworthiness requirements, the tester will identify the relevant defects.
The next steps generally involve understanding the reported issues, obtaining any necessary repairs and arranging a reinspection in accordance with the applicable Victorian process.
You should not assume that clearing a dashboard warning will resolve the defect.
For example, disconnecting the battery or clearing a fault code may make a warning disappear temporarily without repairing the underlying problem. A fault may return, and the vehicle may still fail if it does not meet the required standards.
Instead, ask your mechanic to investigate the cause and confirm what needs to be repaired.
For motorists in Campbellfield, using a workshop that provides both roadworthy inspection services and relevant mechanical repairs may make it easier to understand the issues and organise the next steps.

Roadworthy Inspection vs Diagnostic Scan: What’s the Difference?
A diagnostic scan and a roadworthy inspection serve different purposes.
A diagnostic scan reads information from a vehicle’s electronic control systems and can help identify stored fault codes. It is useful when investigating warning lights and electronic faults.
A roadworthy inspection assesses whether the vehicle meets the applicable minimum safety requirements.
| Diagnostic Scan | Roadworthy Inspection |
|---|---|
| Helps identify electronic fault codes | Assesses applicable roadworthiness requirements |
| Can help investigate dashboard warnings | Examines safety-related vehicle components |
| May require further testing to confirm a fault | Determines whether the vehicle meets the relevant standards |
| Does not issue an RWC | Can result in a Certificate of Roadworthiness if requirements are met |
A diagnostic scan is not a substitute for an RWC, and an RWC is not a guarantee that every electronic or mechanical issue has been identified.
If your dashboard displays a persistent warning, the two processes may complement each other: diagnostics can help investigate the fault, while the licensed tester assesses roadworthiness.
