How Does Alcohol Affect the Driver?
BAC of 0.02: As the person reaches .02 they begin to experience some loss of judgment, relaxation and altered mood which results in a decline in visual functions and ability to perform two tasks at the same time.
BAC of 0.05: Psychomotor performance is significantly impaired; slower eye movements occur; visual perception, reaction time and information processing are adversely affected resulting in reduced coordination, reduced ability to track moving objects, difficulty steering and reduced response to emergency driving situations
BAC of 0.08: Muscle coordination is poor (e.g., balance, speech, vision, reaction time, and hearing), it is harder to detect danger and judgment, self-control, reasoning, and memory are impaired resulting in reduced concentration, short-term memory loss, loss of speed control, reduced information processing capability (e.g., signal detection, visual search) and impaired perception.
How alcohol affects driving?
Many of the functions that we depend on to drive safely are affected when we drink alcohol:
- the brain takes longer to receive messages from the eye
- processing information becomes more difficult
- Instructions to the body’s muscles are delayed resulting in slower reaction times.
- You can also experience blurred and double vision, which affects your ability to see things clearly while you are driving. And youâ€™re more likely to take potentially dangerous risks because you can act on urges you normally repress.
