The DriveCloud+ Alcohol Check application is an app for drivers that works with a breathalyzer to measure the driver's breath alcohol concentration.
The measurement results are sent to the ``Safe Driving Support Cloud Service DriveCloud+ System'' where they are aggregated and centrally managed.
In addition to deterring drivers from driving under the influence of alcohol, it also makes it easier for operation managers to check the results of a driver's alcohol check, and automatically records the evidence.
