Can alcohol in aftershave lotion give a false breathalyzer test?

Yes, alcohol in aftershave lotion can potentially affect a breathalyzer test, but the impact is usually minimal. Breathalyzers measure ethanol, and if a person applies a significant amount of aftershave containing alcohol just before being tested, it might lead to a slight increase in blood alcohol concentration readings. However, this effect is generally temporary and less likely to influence results significantly compared to actual alcohol consumption. It's advisable to avoid using alcohol-based products right before a breathalyzer test to minimize any risk of false readings.
