What are consequences, if any, for fleeing scene of accident and reporting it a mile down the road?

In TX, hit and run is a criminal charge when one does not stop after an auto accident involving death, injury or property damage.  In TX, hit and run/leaving the scene of an accident can range from a misdemeanor to a felony depending on the amount of damage or injury.  TX Transportation Code requires that in an accident involving damage to an occupied vehicle, one must stop as close as possible without obstructing traffic, render aid, provide personal information and show driver's license if requested.  Failure to do so can result in arrest and being held until seeing a judge.  Hit and run involving damage to an occupied vehicle is a Class C misdemeanor with a fine of up to $500 if the damage to all vehicles is less than $200.  It is a Class B misdemeanor with up to six months in jail if the damage is more than $200.

The police report in your case will state the cause of the accident and the party who was at fault.  You can file your property damage claim with the other driver's insurance.  If the other driver does not have insurance, your husband can file a claim with his insurance company if he has uninsured motorist coverage. 

If your husband was injured in the accident, when he completes his medical treatment and is released by the doctor or is declared by the doctor to be permanent and stationary which means he has reached a point where no further improvement is anticipated, he should then obtain his medical bills, medical reports, and documentation of any wage loss.  His personal injury claim is separate from the property damage claim.  The personal injury claim will consist of the medical bills, medical reports, and documentation of wage loss.  Compensation for the medical bills is straight reimbursement.  Compensation for wage loss is straight reimbursement.  The medical reports will document the nature and extent of his injuries and will be used to determine compensation for pain and suffering.  Compensation for pain and suffering is an amount in addition to the medical bills.  If your husband is dissatisfied with settlement offers from the insurance company, he can reject those offers and sue the at-fault driver for negligence.  If the case is settled, no lawsuit is filed.  If the case is NOT settled, the lawsuit must be filed prior to the expiration of the applicable statute of limitations or your husband will lose his rights forever in the matter.

If the other driver did not have insurance and if your husband did not have uninsured motorist coverage, there won't be any claims filed with the insurance company.  In that case, your husband will need to sue the at-fault driver for negligence.  Since people driving without insurance usually have few if any assets, if your husband prevails in the lawsuit, he should obtain a wage garnishment to enforce the judgment against the other driver.
