Traffic Safety

You most likely see yellow or orange traffic barrels everyday if you are a commuter.  You are probably seeing more than you would like now, considering it is construction season.  But what is the different between the orange and yellow traffic barrels?

Yellow traffic barrels are commonly seen at the fork that turns off into an exit, protecting drivers from hitting the concrete median.  Orange traffic barrels usually are lined up on the side of the road to prevent cars from going into construction areas.
