Third-Party Liability Is The Only Legally Required Part

Motor insurance is compulsory almost everywhere, but the compulsion applies to one part of it. The law protects the people a driver harms, not the driver's property.

The purpose behind the statute

A vehicle can cause injuries costing far more than any individual could pay. Without compulsory cover, victims would frequently go uncompensated and the cost would fall elsewhere.

Requiring liability insurance turns an unrecoverable claim into a payable one. The insured driver is the mechanism, not the beneficiary.

This is why the policy responds to the injured party even in circumstances where it might have refused to indemnify its own policyholder.

Why injury cover is usually unlimited

Many jurisdictions require unlimited cover for third-party injury, or set a limit high enough to be effectively unlimited, because catastrophic injury costs cannot be capped safely.

Lifetime care for a severely injured person runs into sums no fixed limit could reliably anticipate decades in advance.

Third-party property damage is different. It is bounded by the value of what can be damaged, so a stated limit is workable and is normally applied.

Comprehensive adds cover for the policyholder

Damage to the insured's own vehicle, fire and theft cover, windscreen benefits and personal effects are all voluntary additions sitting on top of the compulsory element.

Because they are voluntary, insurers can and do restrict them with excesses, conditions and exclusions that could not lawfully be applied to the compulsory part.

That structural difference explains why an insurer can decline to repair a policyholder's car in circumstances where it must still pay the other driver.

The insurer pays and then recovers

Where a policyholder has breached the contract, the insurer may still be obliged to meet a third-party injury claim and then pursue the policyholder for what it paid.

This is the practical meaning of statutory protection. The victim's position is preserved while the contractual dispute is settled separately afterwards.

It is also why fronting and misdescribed use can be financially serious rather than merely voiding a policy quietly.

Uninsured driving fills the same gap differently

Where no insurance exists, most jurisdictions maintain a compensation arrangement funded by insurers to meet claims against uninsured or untraced drivers.

These arrangements typically carry conditions and limits that a direct policy would not, particularly for property damage.

Statutory minimums, limits and compensation arrangements vary considerably by jurisdiction and change over time. The applicable law and the policy wording together determine what is payable.
