The more alcohol a person drinks, the more that person’s ability to drive is hindered. According to the Centers for Disease Control and Prevention (CDC), even a relatively small amount of alcohol, resulting in a blood-alcohol concentration of 0.02 percent, can diminish a driver’s ability to visually track a moving object or perform two tasks at once, such as driving and talking.
Tests have also shown that a BAC of 0.05 percent can impair coordination, reduce response time and cause difficulty steering. Of course, 0.08 percent is the legal limit for drivers in New York and throughout the U.S., but there has been a significant push in recent years to lower the legal BAC for operating a motor vehicle to 0.05 percent.
There is little debate over the effects a BAC of 0.08 percent can have on a driver. Memory, muscle coordination, concentration and information processing become impaired, and these impairments relate to a driver’s reaction time, vision, balance, speech and hearing. If an emergency road situation arises, a driver with a 0.08 BAC may not react in time to avoid a collision.
