One in four parents have helped their children pay for car insurance, according to the AA.
The insurance firm says the cost of insuring learner drivers has increased significantly in recent years — far faster than the rest of the market.
Barry Aldworth from the AA says insurers are less willing to underwrite them — and that means young drivers are taking risks.
He says the responses show the market and the government have so far failed to keep costs down.
One in eight recently-qualified drivers also said they had delayed taking lessons because of the soaring cost of putting a car on the road.
