Road Traffic Act Only Insurance differs from Third Party Only Insurance (detailed below) and is not often sold, unless to underpin, for example, a corporate body wishing to self-insure above the requirements of the Act. It provides the very minimum cover to satisfy the requirements of the Act. Road Traffic Act Only Insurance has a limit of £1,000,000 for damage to third party property, while third party only insurance typically has a greater limit for third party property damage.
 Availability varies. Enrollment discount applies during data collection; final discount is calculated on driving behavior and could be zero. Discounts do not apply to all coverage elements; actual savings vary by state, coverage selections, rating factors and policy changes. Final discount applies at the next policy renewal and remains until drivers or vehicles on the policy change.
