Head-on collision
From Wikipedia, the free encyclopedia
A head-on collision is one where the front ends of two ships, trains, planes or vehicles hit each other, as opposed to a side-collision or rear-end collision.

[edit] Rail transport
With rail, a head-on collision often implies a collision on a single line railway. This usually means that at least one of the trains has passed a signal at danger, or that a signalman has made a major error. Head-on collisions may also occur at junctions, for similar reasons.
With railways, the distance required for a train to stop is usually greater than the distance that can be sighted before the next blind curve, which is why signals and safeworking systems are so important.
In U.S. railroad jargon, they're called a cornfield meet.
[edit] Accidents
Note: if the collision occurs at a station or junction, or trains are travelling in the same direction, then the accident is not a pure head-on collision.

[edit] Sea transport
With shipping, there are two main factors influencing the chance of a head on collision. Firstly, even with radar and radio, it is difficult to tell what course the opposing ships are following. Secondly, big ships have so much momentum, that it is very hard to change course at the last moment.
[edit] Road transport
In the context of freeways, such collisions are particularly difficult to avoid, since freeways were designed to facilitate high-speed travel. The resulting car accidents are often fatal.
Some U.S. states have installed special signage at freeway off-ramps to discourage drivers from going the wrong way. The Manual on Uniform Traffic Control Devices provides instruction on this signage installation in its Section 2E.50 .
