Common Reasons Cars Fail the RTA Test (and How to Avoid Them)

If you’re a car owner in Dubai, you already know that passing the RTA vehicle test is mandatory for registration renewal, ownership transfer, or exporting your car. However, many vehicles fail the test due to issues that could have been easily avoided with a little preparation.

At Tajdeed Vehicle Testing Center, we see hundreds of vehicles every week, and the reasons for failure are often the same. In this article, we’ll cover the most common reasons cars fail the RTA test—and what you can do to make sure your vehicle passes on the first attempt.

1. Worn-Out or Damaged Tyres

Why it fails:
Tires with worn tread, cracks, bulges, or mismatched sizes can cause immediate failure. Tires older than 5 years are also rejected, even if they look fine.

How to avoid it:

• Replace tires before they exceed 5 years.
• Check tread depth reaches to the tire wear indicator (pic no-1)
• Ensure all four tires are of the same size and type.
• Ensure all four tires are not studless or snow tires.
• Ensure all four tires have no cracks or any damage.

2. Faulty Lights and Indicators

Why it fails:
Headlights, brake lights, fog lamps, or indicators that don’t work or are misaligned make your car unsafe.

How to avoid it:

• Test all lights before inspection.
• Replace burned-out bulbs immediately.
• Make sure headlights are aligned properly.
• Make sure all lights have no damages.
  

3. Brake Issues

Why it fails:
Weak or unbalanced brakes, worn pads, or fluid leaks in the braking system can cause failure.

How to avoid it:

• Replace brake pads when worn.
• Get brake fluid checked regularly.
• Service the braking system before your test.
  

4. Oil or Fluid Leaks

Why it fails:
Leaks from the engine, gearbox, or other components can cause environmental hazards and lead to failure.

How to avoid it:

• Check under the vehicle for oil spots.
• Fix leaks before visiting the testing center.
  

5. Excessive Exhaust Smoke & Emissions

Why it fails:
High emissions or black smoke from the exhaust indicates poor engine health and environmental non-compliance.

How to avoid it:

• Regularly service your engine.
• Clean or replace the air filter.
• Use high-quality fuel and engine oil.
  

6. Cracked or Damaged Windshield

Why it fails:
Even small cracks in the windshield can block the driver’s vision and lead to test failure.

How to avoid it:

• Replace or repair the windshield before the test.
• Ensure wipers are working properly.
  

7. Steering & Suspension Problems

Why it fails:
Loose steering, worn suspension, or unstable wheel alignment affects vehicle control.

How to avoid it:

• Get suspension checked during regular servicing.
• Align wheels and check shock absorbers.
  

8. Body Damage or Unsafe Modifications

Why it fails:
Serious dents, rust, or non-approved modifications (e.g., exhaust, lift kits, tinting) can lead to rejection.

How to avoid it:

• Repair visible body damage.
• Remove unapproved modifications.
• Ensure window tint follows UAE regulations.
