Chris Grayling, the justice secretary, is unveiling a range of measures as the coalition comes under pressure to tackle the cost of living following Labour's promise to freeze gas and electricity prices.
He will claim the government's efforts to stop whiplash insurance fraud have already brought down the price of car insurance by £80. In an effort to reduce premiums further, new independent medical panels will assess each claimant from next year, Grayling said.
The government also plans to freeze the maximum price of an MOT for a car at £54.85 until the next election, and it will review the fees relating to driving tests, currently £31 for theory tests, £62 for practical tests and £50 to obtain a provisional licence.
"It's not right that people who cheat the insurance system get away with it while forcing up the price for everyone else, so we are going after whiplash fraudsters and will keep on driving premiums down," the justice secretary said.
The government said statistics from the AA showed that insurance premiums had fallen by 12% in the last year, after new controls were imposed on fees charged by lawyers in personal injury cases.
