Driving is a classic example of visually guided behavior in which the eyes move before some other action. When approaching a bend in the road, a driver looks across to the inside of the curve before turning the steering wheel. Eye and steering movements are tightly linked, with the eyes leading, which allows the parts of the brain that move the eyes to assist the parts of the brain that control the hands on the wheel. We show here that this optimal relationship deteriorates with levels of breath alcohol well within the current UK legal limit for driving. The eyes move later, and coordination reduces. These changes lead to bad performance and can be detected by an automated in-car system, which warns the driver is no longer fit to drive.
驾驶是视觉引导行为的一个典型例子，在这种行为中，眼睛会在其他动作之前移动。当接近道路弯道时，驾驶员在转动方向盘之前会看向弯道内侧。眼睛和转向动作紧密相连，眼睛动作在前，这使得控制眼睛运动的大脑部分能够协助控制方向盘的手部动作的大脑部分。我们在此表明，在英国目前的法定驾驶酒精含量限制范围内，这种最佳关系会随着呼气酒精含量水平的升高而恶化。眼睛的移动会延迟，协调性也会降低。这些变化会导致驾驶表现变差，并且可以通过车内自动化系统检测到，该系统会警告驾驶员不再适合驾驶。
