[0034] The vehicle alcohol lock has switchable unlocking state and locking state. When the alcohol detection mechanism detects that the alcohol concentration of the driver meets the standard, the vehicle alcohol lock enters the unlocking state, the transmission mechanism drives the baffle 110 to avoid the opening 102, so that the ignition switch 2 is exposed outside the housing 1. When the alcohol detection mechanism detects that the alcohol concentration of the driver exceeds the standard, the vehicle alcohol lock enters the locking state, the transmission mechanism drives the baffle 110 to cover the opening 102, so that the ignition switch 2 is hidden in the housing 1.
