The weather in Hawaii is a freezing 70 degrees during the morning hours with a cool tropical breeze flowing from the Windward side of the island. You may need to bring a t-shirt with you and a pair of shorts for those cold November mornings. The day-time however gets to a balmy 85 degrees.
Some freeways have fixed point to point cameras 5km apart so you can't beat them by slowing down for the camera as they will get your average speed between the two points - same deal - 3 km over, fine. Cops will pull you over in their vehicles if they detect you speeding anything over about 4kmh over the speed limit. In Australia speed fining is all about blatant government revenue raising - this despite government propaganda calling them safety cameras.
The Law. It is the driver's responsibility to be aware of the posted speed limit. The maximum speed limit is 65 miles per hour on rural interstates, 55 miles per hour on interstate highways near or in major cities and on other highways, and 30 miles per hour in an urban area unless some other speed restriction is established.
