Fred, are you saying that there is no written permission law?
No, What Fred is saying is that the section pertaining to written permission doesn't apply to a guest. I am your guest if you verbally give me permission or written permission whether you or your agent (if you had one) was present with me or not. If you are not then this section does not apply to me. A simple call or visit to the landowner by the GW will confirm that I had your permission. The DL law doesn't have that clause even though most jurisdictions will throw it out with cost of court. Although the Officer still has discretion and by simply doing a check via dispatch (10-27) can confirm and choose to not write the ticket.
