I know NY state has a law if you have your wipers on you need to have your headlights on. This law makes sense because you want to have as much visibility as possible on the road. Here in ON im not sure if something like this is in place but I do see people who turn on their lights when their wipers are on (some cars do it automatically). I hate seeing dumb people who do not even turn on their lights when its dark. You honk/flash your lights and they are completely oblivious.
Is there something in OHTA specifying that you need both on?
