I think you have to be clear and to the point. Otherwise curiosity seekers and no-goods will ignore signs. Check with the local police for their advice on words. Maybe.....

Private Driveway ("Drive" implies it's not a residential road)
No Trespassing
City Code 12345 (Small letters)

A trespasser called the local police (actually Sheriff, but let's call them
the cops nonetheless).

He felt entitled to the road, and didn't like this little roadblock:

The cops arrived to ask me what happened, and they could easily see the
roadblock.

I told them that I blocked the road, and that I called them last week to
tell them I was blocking the road, and that I told the bikers to go back
and they went right by me using the foulest language you can imagine.

Just one memorable sentence was "you can shove your private road up
your...", right in front of my kids. The kids were appalled more than I was
(as only my best friends talk to me that way); but, when they called the
police, they also used foul language (according to the police).

The police declined to even take down the report, even though they told the
police that I knocked them off their bikes (I never touched them) and when
the cops asked if they had any injuries and if they wanted to press
charges, they declined. The cops didn't believe them.

The cops did show me California Penal Code 602L, which says that in order
for people to be convicted of trespassing, I need to have signage that is
at least 3 per mile and at the entrance & exit to the "trail".
