The Effects of Alcohol on Driving Ability

If an individual chooses to consume alcohol and then drive, it is important for his or her safety and for the safety of others on the roadway that they understand how alcohol can impair driving ability. To legally drive in most cases, a motorist’s blood alcohol content (BAC) must be below .08%. There is no way to determine one’s BAC without the administration of a Breathalyzer or other test, and even then the results may be less than reliable.

It is important to have experienced legal representation by your side if you have been arrested and charged with DUI so that your case can be vigorously defended. The Arizona DUI defense attorneys of Thompson & Volquardsen, P.C., can help you to fight for your legal rights. Contact our offices today at 602-510-9999 to learn more in a free consultation.

Effects of Alcohol on the Body by BAC

The amount of alcohol that you consume will directly affect your BAC. However, different people are affected by alcohol in different ways. Factors influencing this measurement include:

  • Weight
  • Age
  • Frequency of alcohol use
  • The amount and kind of food consumed

Not only does an individual’s BAC vary according to numerous different considerations, but the specific effects that accompany a given level of intoxication can be variable as well. The following represent general impairments associated with the given BAC:

  • .01% to .08 % – Completely functional to slightly impaired judgment, coordination, and concentration
  • .08% to .10% – Impaired vision, reflexes, and reasoning
  • Over .10% – Coordination and judgment extremely impaired, distorted vision, and severely increased reaction time

Your BAC may be difficult for an officer to determine. Breathalyzers can be calibrated incorrectly and field sobriety tests are not always conclusive. Proof of these errors may be the difference between the tough consequences of a DUI and the charge being overturned. It is important to remember there are many ways to defend yourself after arrest.
