In order to increase car passenger safety, the Brazilian National Traffic Council (CONTRAN), released the Resolution 221, defining maximum passenger and driver biomechanical criteria, for the event of a vehicle frontal impact. These vehicle maximum allowed biomechanical injury criteria will be enforced from January 2012, for new vehicles, and in January 2014 for vehicles in production before January 2014. To standardize the test method to measure the driver and front passenger injury values in a frontal crash, Contran's Resolution 221 defines that the tests have to be done according to the ABNT NBR 15300-1 standard, followed by the ABNT NBR 15300-2 standard or the ABNT NBR 15300-3 standard. The use of ABNT NBR 15300-2 or ABNT NBR 15300-3 standards is a free choice for the vehicle's manufacturer.
