According to research from car insurance company LV=, one in 20 adults said they have been contacted within two hours of an accident, by claims companies.
The report also said that a fifth of people were encouraged to make the claim by a police officer, with a number of police forces sharing victims' details in exchange for a fee.
John O'Roarke, managing director of LV= car insurance, said:
The heavy-handed tactics of the claims farming industry has resulted in record levels of compensation claims for whiplash and other personal injuries, despite falling accident rates.
Crash victims are being aggressively targeted by those who can make money out of their details and they are literally hounding them to make a claim within moments of an accident.
