What Is Considered a Minor Defect in MOT Test? Essential Insights for Vehicle Owners

Overview of MOT Tests

MOT tests, or Ministry of Transport tests, assess vehicle safety, roadworthiness, and emissions. Conducted annually for vehicles over three years old, these tests ensure compliance with UK regulations. A certified tester performs the inspection, examining various components that contribute to a vehicle’s overall safety.

During an MOT test, we can expect inspections covering key areas such as:

1. Body and Structure: The examiner checks for signs of corrosion, damage, or excessive wear that could compromise structural integrity.
2. Steering and Suspension: Inspectors evaluate the functionality and condition of steering components and suspension systems, focusing on uniformity and wear indicators.
3. Brakes: Brake performance, effectiveness, and wear are thoroughly analysed to ensure safe stopping ability.
4. Tyres: Tyre tread depth, pressure, and overall condition are crucial factors contributing to road safety. A minimum tread depth of 1.6 mm is required.
5. Lights and Indicators: The operation of all external lights and indicators, including headlamps and reflectors, is examined for correct functionality.
6. Exhaust System: Inspectors assess the exhaust system for leaks, emissions, and adherence to environmental standards.
7. Windshield and Wipers: The condition of the windshield and the effectiveness of wipers in maintaining visibility are closely scrutinised.

In our efforts to maintain vehicle safety, addressing identified minor defects promptly ensures compliance and helps prevent the escalation of issues that could lead to a more significant failure during an MOT test.

Definition of Minor Defects

Minor defects are issues identified during an MOT test that don’t significantly compromise road safety. While not an immediate threat, these defects require attention to maintain vehicle performance and compliance with regulations.

Examples of Minor Defects

• Tyres: Tyres with tread depth below 1.6 mm but above the legal minimum of 1.0 mm are minor defects.
• Lights: Non-functional bulbs, such as side lights or number plate lights, are considered minor defects.
• Windscreen: Small chips or cracks outside the driver’s primary line of sight fall under minor defects.
• Exhaust: Minor leaks in the exhaust system that do not affect emission levels are also classified here.
• Bodywork: Dents or scratches that don’t affect structural integrity are treated as minor defects.

Impact on Vehicle Safety

While minor defects don’t pose immediate risks, they can lead to larger, more severe issues over time. Persistent neglect can compromise vehicle safety and driveability. Addressing minor defects promptly helps ensure a vehicle remains in optimal condition, reducing the likelihood of major failures during future MOT tests. Vehicle owners must recognise the importance of dealing with these issues before they escalate.

Regulations Governing MOT Tests

MOT tests in the UK are governed by strict regulations established by the Driver and Vehicle Standards Agency (DVSA). These regulations ensure uniformity in vehicle assessment, focusing on safety, roadworthiness, and environmental impact. The current guidelines, last updated in 2021, outline the criteria for identifying minor defects and categorising failures.

We must understand the classification of defects during an MOT test, which includes:

1. Minor Defects: Issues that do not significantly impact road safety but require rectification. Examples include:

• Non-functional indicators
• Tyres with tread depth below the legal minimum
• Minor bodywork damage

2. Major Defects: Issues that pose a safety risk. Examples encompass:

• Brakes that fail to function properly
• Worn suspension components that affect vehicle stability

3. Dangerous Defects: Issues that pose an immediate risk to road safety. Examples involve:

• Broken or malfunctioning steering systems
• Defective lighting that impairs visibility

The DVSA mandates that all vehicles aged three years and older undergo an annual MOT test. The test must be conducted by an authorised testing station and performed by a certified MOT tester. Vehicle owners are responsible for ensuring their vehicles are presentable and accessible for the inspection.

Vehicles that pass the MOT test receive a certificate valid for 12 months, while those with minor defects may still pass but necessitate prompt attention. We recommend keeping a record of all identified defects and addressing them to maintain vehicle performance and compliance with legal standards. Neglecting minor defects can lead to increased repair costs in the future and potential complications during subsequent tests.

By adhering to these regulations, we contribute to road safety and ensure that our vehicles remain compliant with the law.

Common Minor Defects in Various Vehicle Types

Understanding minor defects in different vehicle classifications highlights the need for specific attention to maintain safety and compliance during the MOT test. Below, we outline common minor defects in Class 4 and Class 7 vehicles.

Class 4 Vehicles

Class 4 vehicles include cars and small vans. Common minor defects for these vehicles include:

• Tyres: Tread depth under 1.6 mm can lead to reduced grip on roads.
• Lights and Indicators: Non-functional or incorrectly aligned headlights and tail lights impact visibility.
• Windscreen: Small chips or scratches may obstruct the driver’s view but often don’t necessitate immediate replacement.
• Bodywork: Minor rust or superficial scratches, while not dangerous, can eventually worsen if not addressed.
• Exhaust: Small leaks or corrosion can raise emissions without being immediately hazardous.

Class 7 Vehicles

Class 7 vehicles encompass larger vans over 3,000 kg but under 3,500 kg. Minor defects associated with these vehicles often include:

• Brakes: Slight wear on brake pads or discs may indicate the need for replacement but typically does not pose an immediate risk.
• Suspension: Minor corrosion or wear on suspension components, while not critical, can affect ride quality and handling.
• Mirrors: Loose or cracked mirrors require prompt repair to ensure proper visibility.
• Bodywork: Dents or scratches on larger vehicles should be monitored, as they can obscure important safety features.
• Steering: Light play in the steering mechanism can impact driving comfort and should be inspected.

By addressing these minor defects, we can maintain vehicle integrity and ensure compliance with regulations.
