Disable entity driving on a server?

I have searched the wiki and Googled just about every relevent phrase to no avail. How do I make it so that non-admins are unable to drive props?

I’d try and install some prop protection or admin tool, Falco’s Prop Protection might be worth a look at

hook.Add("CanDrive", "CanDrive", function(Player)
	return Player:IsAdmin()

I have Falco’s but, very regrettably, it does not seem to be able to do so.

Most excellent! Thank you very much!

Sorry to bump and old topic but where does one insert this hook?

Just for anyone else, i thro it in Falcos prop protection under its core file, replaced its hook for drive. It worked.
