In the past, police officers used to have certain problems in detecting drunk drivers because the body of each human being reacts differently to alcohol content. Many people can behave in a sober manner when they have substantial alcohol in their bodies while other people can be pretty drunk with only a little amount of alcohol in their blood stream. So, a device known as Passive Alcohol Sensor was produced to overcome this problem.

A Passive Alcohol Sensor is used by police officers to determine the alcohol content in the breath of a driver suspected to be drunk. The basic advantage of this device is that it reduces the time of determining the alcohol content while other devices usually take a little more time and Passive Alcohol Sensors are also said to be more accurate. Usually Passive Alcohol Sensors are used by police officers at field check points and are built into the flashlights used by police officers for convenience. They only need to hold the flashlight at a distance of six to eight inches from the driver’s face and the sensors will catch their breath and determine the alcohol content.

The reason why it is called the ‘Passive’ Alcohol Sensor is the fact that it measures the presence or absence of alcohol in the driver’s breath without their direct participation. During the night-time when most drunk drivers are assumed to be on the road, it is easier and more convenient for police officers to check each driver with their Passive Alcohol Sensors rather than making each driver get out and perform Field Sobriety Tests.

Another advantage of Passive Alcohol Sensors is the fact that many drivers, both drunk and sober do not like to provide breath samples voluntarily and therefore, these sensors are useful in detecting the level of alcohol in a driver’s breath without creating problems for any party. However, some people also point out that getting such breath samples without the consent of the driver is unethical and against the rights of the citizens as stated by the Constitution. However, despite these allegations, devices such as the Passive Alcohol Sensors allow police officers and authorities to effectively perform their job and catch as many drunk drivers as possible in order to reduce drunk driving on the roads and make it a safer place for all people.
