This blog is not affiliated with the National Highway Traffic Safety Administration in any way, shape, or form. Information is taken from the publicly viewable NHTSA Database. Crash tests posted on this blog were conducted between May 21, 1979 and August 17, 1989 at a speed of 35 miles per hour (56 kilometers per hour) into a solid wall with dummies restrained by the vehicle safety belt system. Tests were conducted on the model year vehicle listed in the post and may or may not be accurate for a differing model year. Injury measures are likely accurate to a plus or minus 2% range - for example, a 26% risk of injury is likely in the 24-28% range. The five star system used for 2010 and earlier crash tests is used.

Injury risk:
10% or less - 5 star rating
11% - 20% - 4 star rating
21% - 35% - 3 star rating
36% - 45% - 2 star rating
46% or more - 1 star rating

30 MPH Crash Test - 1978 International Scout

Driver HIC: unknown 
Driver Chest G: unknown
Passenger HIC: unknown
Passenger Chest G: unknown 

Severe Injury Risk: Unknown. See below. Likely above 90% for both occupants.

Test Date: Monday, November 27, 1978

The instrumentation failed 68 milliseconds into the crash. At that time, the head injury criteria measured were negligible (66 for driver and 43 for passenger), as well as passenger chest G's (15 g's). However, the driver had already recorded 90 chest G's, enough that the likelihood of severe injury would be at least 65% based on that alone. Although the measurement was recorded around 55 milliseconds, it is still possible that the peak chest G loading was not recorded and was even more severe than 90 g's. 
The driver's head hit the upper dash with a severe impact and the passenger's head and chest hit the windshield and dashboard with a severe impact. 
Based on the visual evidence, I am estimating the driver's HIC at 1,000 to 2,000, the driver's chest G's at 90 to 110, the passenger's HIC at 1,500 to 2,500, and the passenger's chest G at 70 to 100. It's possible that one or more of the true measurements are outside this range. If the measurements for the occupants were at the low ends of these ranges, the severe injury risk would be 72% for driver and 71% for passenger; at the high end, virtually 100% for each.
