What I read somewhere was 20-30 minutes to contact a lawyer, not to request, and it begins from the moment they read you implied consent.
I actually have no idea if anyone was injured in the accident. I was not given an accident report or a case number, and I have been unable to find this information out as the officers or deputies who interrogated me did not identify themselves. The hospital doesn't know anything, the tow company doesn't know anything.
I did eventually give my blood because I was told I could not speak to a lawyer and if I didn't give my blood my license would be suspended. They gave me no information and this is the most frustrating part of all of this.
I was not arrested, but I was read my rights before being questioned. I was released from the hospital on my own and I would assume that if anyone were seriously injured, I would have been arrested and not been let go. But that's just an assumption.
This may be just the officer's following standard protocol regarding an accident where this is evidence that you were under the influence. I presume that your blood has been sent to a lab for analysis. Once the results are returned, you may be contacted by law enforcement, or a warrant could be issued for your arrest.
The last thing I was told as the officer was leaving was I'd hear from the State Attorney's Office, I'm assuming whether charges would be filed or not.
