have signs that say "End 45 miles/hour" with no indication of the speed limit
Hello, ladymoon ... what a lovely name ... and welcome.
When I lived in California I had to get a license and take the driver's exam. As I recall there are speed limits you are supposed to know for the area you are in i.e. school zone, populated area, and wouldn't you slow to the appropriate speed after the 45 mph zone ended?
a poll of the neighbors indicates no one know what it is.
Perhaps a look at the Driver's Manual you studied before you got your first license ?
REALLY love that name!
wow
