YOU'RE SAFER IN A BIG CAR

A RESEARCH PROGRAMME TO ESTABLISH A RELATIONSHIP BETWEEN DRIVER CRASH INJURY AND PASSENGER CAR WEIGHT IS DESCRIBED. THE STUDY WAS BASED ON CODED REPORTS ON OVER 800,000 VEHICLES INVOLVED IN NORTH CAROLINA CRASHES, AND INCORPORATED OVER 50 PASSENGER CAR GROUPS. INTERIOR DESIGN CHARACTERISTICS OF A CAR ARE IMPORTANT FOR A NON-BELTED DRIVER INVOLVED IN A SINGLE CAR CRASH. THE STUDY OF 23,070 PAIRS OF CARS INVOLVED IN COLLISIONS DEMONSTRATED THAT DRIVERS OF SMALL CARS WERE MOST OFTEN INJURED IRRESPECTIVE OF DIRECTION OF IMPACT OR SPEED. WHEN TWO CARS OF SIMILAR WEIGHT COLLIDE FRONT-TO-SIDE, THE % OF SERIOUS AND FATAL INJURIES IS HIGHER FOR THE CAR STRUCK IN THE SIDE. IMPROVEMENTS IN SAFETY DESIGN OF NEW CAR MODELS HAVE LED TO A DECREASE IN THE ASSOCIATION BETWEEN OCCUPANT INJURY AND CAR WEIGHT. PREDETERMINED FRONT AND REAR COLLAPSABLE ZONES DISPERSE THE ENERGY OF A CRASH. THE DRIVERS STUDIED WERE DIVIDED INTO GROUPS ACCORDING TO THEIR ESTIMATED SPEED OF TRAVEL AT THE TIME OF THE ACCIDENT. THE % KILLED IN THE 50+ MPH GROUP WAS 15 TIMES GREATER THAN IN THE 0-29MPH GROUP. IT IS CONCLUDED THAT DRIVERS OF BIG CARS HAVE A BETTER CHANCE OF SURVIVING TRAFFIC ACCIDENTS THAN DRIVERS OF SMALL CARS.
