6 Critical Mistakes That Lead to Insurance Claim Rejection (Car & Truck Insurance)

Although insurance is essential for both cars and trucks, a lack of proper understanding can easily lead to costly mistakes—resulting in denied claims. Below are the most common errors vehicle owners make when purchasing and using motor insurance.

3 Sai lầm nghiêm trọng dẫn đến bị từ chối bồi thường bảo hiểm

Ignoring Policyholder Responsibilities and Obligations

Many people assume that once they purchase motor insurance, the insurer is obligated to compensate for any damage. This is incorrect. Insurance coverage typically applies only to unforeseen and accidental events, such as:

  • Fire or explosion damage
  • Collisions (including impact with external objects), rollover, sinking, deformation, or mechanical damage
  • Natural disasters: storms, floods, lightning, tsunamis, earthquakes
  • Theft or robbery of the vehicle
  • Vandalism or intentional damage by third parties

However, even in these cases, failure to fulfill the policyholder’s obligations—such as properly safeguarding the vehicle—may result in claim denial.

Additionally, if the damage is caused by a third party, liability lies with that party. The vehicle owner must either claim directly from the third party or authorize subrogation for the insurer to recover costs.

Failing to Notify the Insurance Company After an Incident

Under current motor insurance regulations, failure to notify the insurer at the time of the incident may lead to a 10–20% reduction or rejection of the claim—even if subsequent procedures are followed correctly.

Similarly, lack of photo or video evidence of the accident scene may also result in partial claim denial. Always report the incident to your insurer immediately to secure your full benefits.

Reporting Multiple Incidents in a Single Claim

Some vehicle owners believe they can combine multiple minor incidents over a week or month into a single claim. This is a serious mistake.

While minor scratches may be processed quickly without detailed documentation, grouping multiple damages makes claim verification difficult and may lead to rejection.

Especially avoid overlapping new incidents with previously unreported ones. Therefore, best practice: Report each incident separately and promptly for proper claim processing.

Fraudulent Behavior or Intentional Damage

Any attempt to commit insurance fraud—such as staging accidents, intentional damage, or arson—will result in immediate claim denial and possible legal consequences.

Unauthorized vehicle modifications (e.g., removing safety features or illegal alterations) prior to an incident can also void coverage. These violations are easily detected through inspections or surveillance systems.

Not Following the Claims Procedure

Failure to comply with the claims process is a common reason for rejection. This includes:

  • Late notification (typically beyond 24–72 hours, depending on policy terms)
  • Repairing the vehicle before inspection
  • Missing required documents (photos, police reports, inspection records)

For example, in cases of flooding or hydrolock, attempting to restart the engine instead of calling roadside assistance can worsen damage and invalidate coverage.

Using the vehicle for purposes outside its registered use (e.g., using a cargo truck for passenger transport) may also lead to claim denial.

Expired Policy or Exclusion Clauses

Claims will be rejected if:

  • Premiums are not paid on time
  • The incident occurs before the policy becomes effective
  • The damage falls under exclusion clauses (e.g., war, uninsured natural disasters)

Many vehicle owners fail to read policy terms carefully, especially confusing mandatory liability insurance with voluntary coverage—a common issue in commercial truck insurance.

Conclusion

The most serious mistakes leading to insurance claim rejection often involve legal violations, fraud, or failure to follow contractual procedures.

To protect your rights and financial interests, both individuals and businesses should carefully review policy terms, understand their responsibilities, and strictly follow claim procedures.
