When appropriate (Late hours) in familiar areas with a good line of sight of the other roads, I'll roll through them with some speed. It's a common sense thing; if there's other traffic then come to a complete stop and use right of way, and don't roll signs where you don't have a clear line of sight of the cross road well before the sign.
One point that should be noted that in Texas, if you're ticketed at a sign that is not DOT approved, you can often fight the ticket. I heard this tactic years ago, and I don't know if the loop hole still works, so don't test my theory..
