An Oireachtas Committee has called on the Government to consider holding a referendum on the introduction of random testing of motorists for substance use.
The Enterprise and Small Business Committee made the call in a bid to reduce the number of deaths on the roads.
Committee chairman, Donie Cassidy, TD, said if a referendum is necessary, one could be held at election time.
It is also recommending that transition year students study the driver theory test.
The recommendations are contained in the committee's third interim report on Reforms of the Insurance Market, which has been published.
Meanwhile, the Department of Transport has totally rejected claims by the Irish Insurance Federation that the National Road Safety Strategy has failed.
The IIF says the three-year strategy, which is already two years old, has failed to tackle road deaths effectively and has not been fully implemented.
The department says the current Government is the first to introduce penalty points and a Traffic Corps, and that legislation to cover the introduction of speed cameras is soon to be introduced.
The federation says there is a lack of political will on the issue and it is calling for greater action.
Niall Doyle of the IIF says lives can be saved if the strategy is fully implemented.
The IIF says no further consultation with international experts is needed as a strategy, which could save as many as 200 lives a year, is currently in place.
