| 2.Dummy of new testing method |
why the new NPRM?
- NHTSA estimates when fully implemented will save 700-1000 lives per year
- Protection to wide range of occupant sizes
- Expand injury criteria to include head region
- For a greater population of vehicles
- Over a broader range of seating position

Based on 32,335 fatalities in the year 2002. According to Pie Chart 1,approx. 7400 fatalities were due to side impact, of those approx. 4500 fatalities(from Pie Chart 2) were due to side impacts with narrow objects or other LTVS. |
Old Vs. New
| Existing Pole Test (FMVSS 201P) |
Proposed Pole Test (Upgraded FMVSS 214) |
| Test speed = 29kph |
Test speed = 32kph |
| Vehicle Angle = 90° |
Vehicle Angle = 75° |
| Dummies = SIDHIII 50th percentile male |
Dummies = SID2S-FRG, ES2-RE |
| Head Injuries |
Head, Thorax and Pelvic Injuries |
| Note: The setup for the proposed pole test is similar to the setup for the existing pole test. |
