Red means stop.
And if you're one of those who doesn't stop when the traffic light turns red, maybe you'll stop for the red flashing lights on the cop car behind you.
Madison Police, along with the Safe Community Coalition, were on hand watching for red light runners along Stoughton road this morning.
There are four high crash areas along that road and running a red light to get where you're going a few seconds quicker isn't worth the risk.
Really we need to slow down a little bit for our own safety, for our family's safety, and it's a matter of seconds that you save, really to save a life, says Cheryl Wittke of the Safe Community Coalition.
Wittke says most traffic lights in the Madison area cycle through in about a minute, so a red lights not going to delay you for all that long.
