I drive a 2000 mustang coupe. Friday, May 25, 2001, I rear ended a semi truck going 25-30 moh on Interstate 10 in Houston, Texas. There is severe damage to the front end of car more so on driver's side because of the angle I hit. At impact neither driver nor pasenger side air bags deployed sending me into steering wheel. Also the seat belt did not lock until I had already hit steering wheel, jerking me back into my seat further injuring my back. I do not have life threatening injuries but I would like to know if there is anything that I can do about the air bags. What are they for if not to atleast protect drivers from MVAs that involve severe frontal damages? Is an 18-wheeler not enough impact? Please help.
