Is it illegal/ticketable to cut through a parking lot to avoid a traffic light?

Drivers on James Island were frequently making right turns on a side street off Camp to avoid the bottleneck at the light on Folly. Residents complained about all that traffic, so a no right turn sign from 6AM-8AM was put up. Many drivers ignore the sign, but I don’t know if any got a ticket.

A similar situation was on Fleming Rd near the tennis courts. One of the residents was a city council member and had such a sign put up on her side street before Maybank. I don’t think it was ever enforced, and the public outcry was such that the sign was eventually removed.

Well this is in a predominantly residential area in the suburbs… I doubt many other people take this shortcut. Certainly not enough to put up a sign.

The default for public streets is that you can drive on them, even in a residential area.
