(a) 
The owner, his agent or his tenant may post signs prohibiting vehicular traffic on the private property upon which they are posted.

The signs shall be 18 inches by 18 inches on a white background with three inch high red letters and shall be posted in a manner so that they are clearly visible at normal entrances to the property.
