Car insurance policy explained: Coverage, benefits & how to choose the right plan

Buying a car insurance policy is easy. Choosing the right one is where most people get confused.

Many car owners focus only on getting the lowest premium. Unfortunately, that often leads to unpleasant surprises during a claim. A policy with limited coverage or a lower Insured Declared Value (IDV) may save you money today but could leave you paying much more after an accident.

This guide explains everything you need to know about a car insurance policy, from coverage and exclusions to IDV, add-ons, claims and renewal tips, so you can make an informed decision.

Why is a car insurance policy important?

A car insurance policy protects you financially against unexpected expenses arising from accidents, theft, fire, natural disasters and third-party liabilities.

In India, every vehicle on public roads must have at least third-party insurance under the Motor Vehicles Act. However, experts and IRDAI recommend opting for comprehensive insurance because it covers both third-party liability and damage to your own vehicle.

Types of car insurance policies

According to IRDAI, comprehensive policies provide broader financial protection than liability-only policies because they cover accidental damage to your own vehicle as well.

What does a comprehensive car insurance policy cover?

A comprehensive policy generally includes:

a. Accidental damage

Repairs or replacement costs if your car is damaged in an accident.

b. Theft

Compensation if your vehicle is stolen and not recovered.

c. Fire damage

Coverage against fire, explosions, or self-ignition.

d. Natural disasters

Protection against floods, cyclones, earthquakes, landslides, and storms.

e. Man-made disasters

Damage caused by riots, vandalism, or malicious acts.

f. Third-party liability

Financial protection against injury, death, or property damage caused to another person.

Coverage varies between insurers, so always read the policy wording before purchasing.

Common exclusions you should know.

No insurance policy covers everything.

Most car insurance policies exclude:

• Normal wear and tear
• Mechanical or electrical breakdown
• Driving without a valid license
• Driving under the influence of alcohol or drugs
• Consequential damage due to negligence
• Damage occurring outside the policy period
• Illegal usage of the vehicle

Understanding exclusions helps avoid claim rejections later.

What is IDV in car insurance?

One of the most important terms in any car insurance policy is IDV (Insured Declared Value).

Simply put, IDV is the current market value of your car after accounting for depreciation. It represents the maximum amount your insurer will pay if the vehicle is stolen or declared a total loss.

For example:

Choosing a lower IDV reduces your premium but also lowers your claim payout.

IRDAI advises policyholders to compare not only premiums but also IDV while selecting a policy.

Popular add-on covers worth considering

A basic policy may not provide complete financial protection. Add-ons help bridge those gaps.

Zero depreciation cover

Also called Zero Dep Insurance, this add-on ensures depreciation is not deducted while settling claims for replaced parts, reducing your out-of-pocket expenses.

Engine protection

Useful if your area is prone to flooding or waterlogging. It covers engine damage that is otherwise excluded.

Return to invoice cover.

If your new car is stolen or suffers total loss, this add-on helps compensate the difference between the invoice value and the claim amount.

Roadside assistance

Provides emergency support such as:

• Flat tyre assistance
• Towing
• Battery jump-start
• Fuel delivery
• Minor repairs
• Consumables cover

Pays for items usually excluded during repairs, such as:

• Engine oil
• Brake oil
• Coolant
• Nuts and bolts

How to choose the right plan for a car insurance policy

Not every policy suits every driver.

Consider these factors before selecting a plan for a car insurance policy.

1. Choose comprehensive coverage

If your car is relatively new or regularly used, comprehensive insurance usually offers better financial protection.

2. Compare the IDV

Don't compare premiums alone.

A lower premium with a significantly lower IDV could reduce your claim amount substantially.

IRDAI specifically advises comparing deductibles, coverage and IDV before purchasing a policy.

3. Select relevant add-ons

Choose add-ons based on your driving habits.

For example:

• Zero Depreciation for newer cars
• Engine Protection for flood-prone cities
• Roadside Assistance for frequent travellers

4. Check cashless garage network

A wider network of authorised garages can make repairs and claims much smoother.

5. Review the claim settlement process

Look for insurers with:

• Digital claim support
• Quick survey process
• Transparent documentation
• Good customer service

How does the car insurance claim process work?

Most insurers follow a similar process.

Step 1

Inform your insurer immediately after the accident.

Step 2

Register the claim online, through the mobile app or customer care.

Step 3

Upload required documents, such as the following:

• Policy copy
• RC
• Driving licence
• Claim form
• Repair estimate
• FIR (where applicable)

IRDAI also lists these as commonly required documents for motor insurance claims.

Step 4

A surveyor inspects the vehicle.

Step 5

The vehicle is repaired.

Step 6

The claim is settled either through cashless repair or reimbursement.

Tips for renewing your car insurance policy

Renewing your policy on time is just as important as buying it.

Here are a few practical tips.

1. Renew before expiry

IRDAI recommends approaching your insurer at least 15 days before the policy expires.

2. Don't lose your No Claim Bonus.

A No Claim Bonus (NCB) can range from 20% to 50% on the own damage premium for consecutive claim-free years.

Even if you switch insurers, your accumulated NCB can usually be transferred.
3. Review your IDV every year.

As your car depreciates, review the IDV to ensure it reflects its current market value.

4. Reassess your add-ons

Your insurance needs may change over time. Keep only those add-ons that continue to provide value.

Final thoughts

A car insurance policy is much more than a legal requirement. It is a financial safety net that protects you from unexpected repair bills, theft, accidents and third-party liabilities.

Instead of choosing a policy based only on the lowest premium, evaluate the overall protection it offers. Compare the IDV, understand the inclusions and exclusions, choose meaningful add-ons and renew your policy before it expires. A little research today can save you significant expenses when you need your insurance the most.
