Formal or familiar command in written instructions?

Question

I want to write what is allowed and not allowed while visiting a park.

Should I use:

¡No toques las flores! (familiar, tú command) or

¡No toque las flores! (formal, Ud. command)

HI mag, use the formal command, it can be used everywhere

Customary to use with strangers. What do you do with all of the pets that can not read Spanish. The ones that like to water the flowers. - 0074b507, Sep 22, 2011
