[Question - Other] Driving licence blood type: Dangerous if wrong?

While I was in Mexico I got myself a driving licence and one of the questions was “what is your blood type”. I am from the UK and they generally don’t tell you your blood type. I was in hospital a few years ago and I asked for my blood type and I’m pretty sure they told me it was O- but I’m not 100% sure. I told the guy to put O- on my licence. I read that O- is universal so worst case scenario, even if I am mistaken and my blood type is not O- then it will still be ok. Is that true?
