Motorists have been warned of the consequences of "swapping" points in order to avoid driving bans after new research found that figures are on the increase.
Direct Line found that 2% of motorists have managed to get partners to take the blame for their driving offences.
In a survey carried out three years ago, the figure was 1.5%.
London is the worst area for point swapping offenders, with as many at 7% of motorists coming to an agreement to keep points off their licence.
The survey of 2,009 adults also revealed that 4% of those aged 18-35 have taken part in a point swapping arrangement.
Andy Goldby, director of motor underwriting at Direct Line, said: "Motorists are increasingly risking perverting the course of justice in order to maintain a clean licence, as well as to avoid a driving ban.
"However, trying to escape convictions by swapping points with another person is illegal and can lead to prosecution. Quite simply, it is not worth the risk."
