What does impaired depth perception cause in drinking drivers?

Impaired depth perception in drinking drivers can lead to difficulty judging distances and the speed of oncoming vehicles, increasing the risk of collisions. This impairment can result in problems with lane positioning and the ability to accurately assess the space required for safe maneuvers, such as turns and merges. Overall, it significantly hampers a driver's ability to react appropriately to dynamic road conditions, further heightening the dangers associated with impaired driving.
