Variations among individuals and other factors, such as altitude
and air temperature, affect the degree of intoxication. some
individuals may become intoxicated at low BaC levels. a low
BaC on a breath alcohol tester does not mean that a person’s
reaction times can respond to any emergency encountered.
Individuals should not drink alcohol and drive or use any
machinery after consuming alcohol.
How does alcohol affect my driving?
we can’t emphasize enough how dangerous it is for you to
drink and drive. Your vision and your brain are the most
important factors in driving safely. If you jeopardize either by
drinking, and then you drive, you are likely to be involved in
a serious or fatal collision.
There is no safe way to drive under the influence of
alcohol. Even one drink can make you unsafe.
