The Irish Insurance Federation (IIF) has agreed to implement four of the Motor Insurance Advisory Board's (MIAB) recommendations from 1 August.
The IIF's motor insurer members will provide no claims discounts to retirees seeking motor insurance in their own names by giving credit for previous insurance experience as drivers of company vehicles insured by their employers.
It will not restrict cover or load the premiums of drivers with disabilities, unless there is evidence of additional risk.
And the IIF will not seek "supporting business" in another class of insurance as a precondition for quoting for motor insurance.
These undertakings cover the MIAB's recommendations 10, 11 and 18.
The IIF will also support recommendation 48 that all claims for loss of earnings due to injury should be supported by documentary proof from revenue and social welfare.
However, IIF chief executive Michael Kemp pointed out that the implementation of recommendation 48 and the majority of the MIAB's other recommendations were not in the hands of insurers, but the legal industry and government.
