Talk:Mandatory sign

One-way sign
How would one describe the "One-way sign" that is in use in the Unites States? It seems to be a mandadory sign. —Preceding unsigned comment added by 194.151.163.166 (talk) 08:26, 19 September 2007 (UTC)
 * It's a plain, partially plain text regulatory sign, and sometimes has a black background. Australia has the same thing. Jordf32123 (talk) 07:34, 22 January 2022 (UTC)

Safety sign
Hi, I was thinking mandatory signs as in safety signs which use similar symbols. Is there somewhere that talks about safety shapes outside of roads? Jordf32123 (talk) 07:35, 22 January 2022 (UTC)
