Auto insurance claims that may be fraudulent can either be soft fraudulent insurance claims or hard fraudulent insurance claims. Insurance adjustors have within their means ways of spotting either type of fraudulent auto insurance claims if they can prove that the claimant is deliberately involved in such criminal behavior by doing some simple investigation to verify the claims made by the claimants.
A type of soft fraudulent claim can be spotted if the insured files repeatedly for the same injury, files for injuries that were not caused by an auto accident, claims to have been deprived of more work related income than he or she actually earns or files for more costs in repairing the damaged auto than was actually paid to have it repaired.

Examples of hard fraudulent auto insurance claims involve criminal behavior like staging auto accidents in order to file a claim. Other readily spottable bogus claims come from filing a claim for an accident that the claimant was not even involved in or filing for repair costs or for medical treatments that were never done.

In some cases, if a certain car is over insured, accidents like rear end collisions are staged to have the claimants who were rear ended file for medical damages against the bumper's auto insurance. There are cases where a car is packed with passengers and is deliberately stopped in traffic to have the over insured car following bump the rear of the car with the passengers. All of the passengers then file for medical injuries against the insurance held by the car that bumped them. The claims are obviously bogus but proving them would mean paying an investigator to prove collusion between the car accident orchestrators.

Auto accidents that have no real serious injuries or damage but involve settlements paid for medical injuries or inflated repair costs that might even be more than the car is actually worth are easily spottable as bogus claims. In some cases, autos are insured for more than they are worth and are wrecked deliberately for the insurance money. Proving bogus claims are obviously more difficult than spotting bogus claims.
