 The NTSB issued Safety Recommendation Report HSR1902 in September 2019, entitled "Providing Occupant Protection for Limousine Passengers".In the report, the NTSB determined the crash was not survivable for the limousine driver as the front seating compartment suffered a "complete loss of occupant survival space".The rear passenger compartment was able to retain survival space, but the additional seats and seat belt restraints installed during the limousine extension were not adequately anchored, nor were they properly designed for crash protection.
