The number of "crash for cash" cases is on the increase according to new research, with fake motor insurance claims now the most expensive and common type of insurance fraud to be exposed.
Sometimes, fraudsters will deliberately slam their brakes on so that an innocent motorist hits them from behind, or they will flash their headlights to pretend that they are going to let a driver out of a junction and then deliberately hit them.
On their own, crash for cash claims represent approximately £120 million of financial exposure to insurers, and the Insurance Fraud Bureau is currently supporting police forces and insurers across the UK to investigate 110 "crash for cash" scams where motor accidents are deliberately staged.
The AIB says insurers exposed a record total of £1.3 billion worth of fraudulent claims of all types last year, as the industry steps up the war on cheats.
This marks an 18% rise in value on 2012 and equates to £3.5 million worth of insurance frauds being uncovered every day.
The AIB said there has also been a "significant" increase in people phoning up to report suspected fraudsters, indicating a growing acknowledgement that this is not a "victimless" crime.
Some 118,500 bogus or exaggerated insurance claims were detected in 2013, working out at the equivalent of over 2,000 a week.
While there was a small fall in the number of detected frauds, their value has increased. The average fraud detected across all types of insurance products is worth £10,813.
The rise in the average value of insurance scams could be seen as a reflection of the high-end nature of frauds by organised gangs that are increasingly being uncovered.
Aidan Kerr, the ABI's assistant director, head of fraud, said: "The message is clear: never has it been harder to get away with committing insurance fraud; never have the penalties - ranging from a custodial sentence and a criminal record to difficulties in obtaining financial products in the future - been so severe."
