Of a collision, from the front or in the direction of motion.

With the front of a vehicle.
Wave direction and frequency (period) are two factors that influence the effect of waves on a moored ship. Whether the ship responds by surging, swaying or yawing will depend on whether the waves are striking the moored vessel head-on, beam-on or quartering, the frequency of the waves and the manner in which the tanker is moored.
With direct confrontation.
During the day conditions worsened quickly—for example, a 2-6-0 on the Uckfield line suddenly encountered flood water high enough to enter its ashpan and extinguish its fire—until lock gates up-river at Barcombe gave way and a tidal wave rolled down the valley meeting head-on a spring tide rolling up from the coast.
And there is little research to address the issue head on. A previous study, published in 2000, surveyed doctors and found that three quarters of them said some patients addressed them by their first name.
