When a person is involved in an accident, the medical expenses are typically processed under the injury victim's automobile policy regardless of who was at fault of the automobile accident. Even if a person is injured by a drunk driver, the medical bills up front get processed under the injury victim's PIP automobile policy assuming that the injury victim owns a vehicle that has coverage. If the injury victim does not own the vehicle and then there is a search or investigation for other policies which may cover the injury victim under the PIP coverage for the automobile insurance policy.
A person can still pursue a claim or case against the at fault driver and / or at fault owner even if there was a delay of 14 days int getting the initial treatment following an accident. However, it should be noted that an automobile accident claim and treatment are made a bit easier when PIP is available to pay for medical bills incurred due to accident related personal injuries.
The 14 day requirement and other requirements under Florida law can be quite confusing and complicated. As such, it typically is advisable for an injury victim to consult with a Florida Personal Injury Lawyer to discuss the respective rights of the injury victim.
