Owning a car isn't just about driving it places; it also includes the responsibility of keeping it roadworthy and safe.

One of the most crucial steps is the annual vehicle inspection, often referred to as "ต.ร.อ." (Vehicle Inspection for Annual Tax Renewal) in Thailand. But why do we need to do it, and what exactly gets inspected? This article has the answers.

Why is Annual Vehicle Inspection Important?

Annual vehicle inspection is vital for several reasons, encompassing legal requirements, safety, and vehicle performance:

1. Legal Obligation

According to the Motor Vehicle Act B.E. 2522 (1979), all vehicles that have been in use for more than 7 years (for private passenger cars with not more than 7 seats) or more than 5 years (for trucks and public transport vehicles) must undergo an annual vehicle inspection at a private Vehicle Inspection Station (VIS) authorized by the Department of Land Transport. Without passing this inspection, you cannot renew your annual vehicle tax.

2. Driving Safety

This is the most critical reason. Vehicle inspection ensures your car is in a safe and roadworthy condition, covering the braking system, lighting, tire condition, and other safety-related components. If any abnormalities are found, they can be addressed before unexpected accidents occur.

3. Environmental Preservation

A well-maintained vehicle will have more complete fuel combustion, reducing air pollution emissions. This contributes to environmental protection.

4. Long-term Cost Savings

Detecting minor abnormalities early can prevent major damage that might lead to much more expensive repairs in the future. For example, replacing small worn parts is better than having to replace an entire system.

5. Extending Vehicle Lifespan

When a car is regularly maintained and inspected, its components tend to work efficiently and last longer.

Which Vehicles Require Inspection?

• Private passenger cars (not exceeding 7 seats) that are 7 years old or older (calculated from the registration date).
• Private passenger cars (exceeding 7 seats) that are 10 years old or older.
• Private pickup trucks that are 7 years old or older.
• Motorcycles that are 5 years old or older.
• Other vehicle types as specified by the Department of Land Transport.

What Gets Checked During an Annual Vehicle Inspection?

The vehicle inspection by a VIS covers various key areas:

1. Lighting and Signal Systems:

• • Headlights (high-low beam), taillights, turn signals (front-rear-side), brake lights (including the third brake light), reverse lights.
  • Intensity and aiming of headlights.

2. Braking System

• • Efficiency of parking brake and foot brake (measured by braking force values).
  • Inspection for leaks or abnormalities in brake lines.

3. Tires and Wheels

• • Tread condition, sidewall condition, abnormal wear.
  • Integrity of wheels and lug nuts.

4. Suspension and Steering System

• • Ball joints, tie rods, drag links, shock absorbers, springs.
  • Excessive play in the steering wheel.

5. Engine and Transmission System

• • Inspection for oil or coolant leaks.
  • Stability of engine mounts.

6. Exhaust System

• • Exhaust noise level must not exceed specified standards.
  • Measurement of exhaust smoke opacity (for diesel engines) and carbon monoxide/hydrocarbon levels (for gasoline engines).

7. Other Components

• • Windshield (must not have cracks obstructing visibility).
  • Horn (must be clear and audible).
  • Wipers and washer system.
  • Vehicle body condition (no unauthorized modifications from registration).
  • Seats and seatbelts.
  • Car tools and equipment (spare tire, jack, wrench).

Additional Recommendations

• Before taking your car for inspection, you should perform a basic self-check, such as verifying all lights work, ensuring tires are properly inflated, and cleaning the car. This helps ensure a smooth inspection and reduces the chance of failing.
• If you are unsure about any problems with your car, it's advisable to take it to a garage or service center for repairs before the inspection.

Annual vehicle inspection is not just about complying with the law; it's an investment in your safety, the safety of other road users, and a way to ensure your valuable asset serves you efficiently for as long as possible.
