Alcohol detection system for buses
A breath alcohol tester on the dashboard checks the driver before every trip. The result is sent to vehicle control and the fleet platform, so a failed test keeps engine-start authorisation blocked and the operator is alerted.
Features
- Breath test before startEvery trip begins with a logged test.
- Pass / fail to vehicle controlEngine-start authorisation follows the result (validated per vehicle).
- Operator alertsFailed tests notify the fleet team with time, vehicle and driver.
- Driver verificationCombine with face verification so only the authenticated driver can test and drive.
How it works
- The driver takes the handset from the dashboard.
- They blow into the mouthpiece.
- The device measures the sample.
- Pass enables start; fail keeps it blocked and alerts the operator.
