What type of fatal collision was a person more likely to be involved in when drink driving?

When considering the impact of drink driving on the likelihood of fatal collisions, a single vehicle collision is particularly relevant. This type of collision often occurs when a driver loses control of their vehicle, which can be exacerbated by alcohol consumption. Impaired judgment and diminished reflexes may lead a driver to veer off the road, hit a stationary object (such as a tree or guardrail), or crash in a manner that doesn't involve other vehicles.

In contrast, multi-vehicle collisions typically involve interactions with other drivers and require a different set of circumstances that are not as directly influenced by alcohol impairment. Head-on collisions often necessitate a specific alignment of vehicles that may not necessarily relate to a driver’s impairment in the same way a single vehicle incident does. Rear-end collisions, while they can be influenced by factors related to impaired driving, involve a different dynamic where one vehicle is struck from behind, often in more complex traffic situations.

Driving under the influence significantly increases the risk of losing control of one's own vehicle, making single vehicle collisions the most likely scenario when evaluating the risks associated with alcohol use while driving.
