Rules. Laws. Regs. Do this; do that.

Here’s another regulation for motorists that kicks in Tuesday -- and one that makes things safer for everyone: When it rains, or if its foggy: your headlights must be on. Must.

If you don’t: you can get a ticket and your insurance bill may go up.

The law says when there is “insufficient light or unfavorable atmospheric conditions,” or when visibility is under 500 feet, or anytime windshield wipers are on, your headlights must be shining.

The law, Chapter 481 of the Acts of 2014,  was passed in January.
