The Liberal government agreed to an NDP demand for a 15 per cent cut in car insurance rates over two years in order to get last year's provincial budget passed.
NDP critic Jagmeet Singh had said his party believed the Liberals were nowhere near meeting their promised goal of an average eight per cent cut in the first year.
Singh says the New Democrats are willing to look at what's in the 2014 Liberal budget before deciding whether or not to support it.
But he notes the Liberals have yet to keep last year's budget promises to the party.
It's widely expected this year's budget could trigger a general election, whether by the Liberals' design or because the NDP agree to team up with the Progressive Conservatives to defeat the minority government.
