    Explanation:

    Equation for Impact

    FΔt = ΔP,

    F = force

    Δt  = Impact of time

    ΔP = Change in momentum

    Car steering is engineered to fail in order to maximize the time of contact and hence reduce the initial impact and mitigate the damage incurred.

    Road guard railing crumple on contact to maximize impact time and hence reduce impact intensity and mitigate damage.

    Road safety containers are loaded with liquid or sand as they improve the period of impact.
