Police officers are said to be anxiously awaiting legislation to be enacted that will see the introduction of speed guns and breathalyser tests when it comes to those who drive above the speed limit and are under the influence of alcohol while driving.
The legislation is said to be in the making to make it possible for the police to prosecute offenders who drive above the speed limit or those who drive-drink, using speed guns and breathalyzer tests to secure convictions.
Last year more persons died on the roads than those who were murdered.
How can a person’s breath show how much that person has had to drink?
Alcohol that a person drinks shows up in the breath because it gets absorbed from the mouth, throat, stomach and intestines into the bloodstream.
Alcohol is not digested upon absorption or chemically changed in the bloodstream. As the blood goes through the lungs, a physiologically predictable amount of the alcohol will move across the lung membranes and into the lungs themselves.
Once in contact with the air in the lungs, it evaporates and is exhaled. The concentration of the alcohol in the air in the lungs is directly related to the concentration of the alcohol in the blood.
