The best way to be sure

Hi, from time to time i want to check can i drive, so i wonder what is the best way to be sure that you can drive after party e.g next morinig?

Hello! I think you should consider buying a breathalyze or simply dont drive after drinking.

I agree with Henry, but you can also try online calculators webs or apps, e.g. alcohol-unit-calculator.co.uk if you dont want to spend money.

Does it calculate properly at all? I always wondered how does it work

You must fill the text fields and it calculates if you can or cannot drive, It is based on a mathematical algorithm, it should be similar to standard testers, ofc you should use it with a margin of error.

Thanks a lot, i will try it
