Traffic Drums mean Construction

Commuting to work you may notice a large amount of traffic drums or traffic barrels on the side of the road.  They mean construction season because they are used to barricade the traffic from the construction on the side of the road.  You may even see blinking barricade lights on top of the traffic drum.

Traffic drums are typically either orange or yellow.  The orange ones have reflective bands, and the yellow ones are bigger and are usually found at the off ramps for exits.  They are filled with sand and used to cushion any potential impact.
