Do bulletproof vests made of Twaron or Kevlar offer protection from blunt trauma?

I understand how bulletproof vests' intricately woven fibers stop bullets and spread the blunt-force trauma caused by stopping a powerful projectile over a wider area. Does it also protect against blunt force strikes in a similar manner, spreading the impact over a wider area?
So, in greater detail, would a 3.5 mm level II-A vest provide much vital organ protection in a car accident?

Bullet-resistant vests are designed to provide penetration resistance since your skin and organs are very suseptible to puncture. Your body still bears the entire energy exerted by the projectile. That energy is spread out by the kevlar over a larger area than the projectile diameter and therefore does not penetrate the body. A blunt force impact is spread out a little bit by the vest but the body still sees the same energy over a slightly increased area. The only real effect you would get by the vest is the additional padding by the material.
