Traffic Barricades, Type 1 2 and 3

What are traffic barricades?  A traffic barricade is a type 1, type 2, or type 3 barricade that obstructs or directs traffic in a certain direction.  Type III or type 3 barricades have 3 panels going across the barricade horizontally, usually between 4 and 10 feet wide.  A type II or type 2 barricade has 3 panels going across the barricade horizontally, and is only about 1-2 feet wide.

A type I or type 1 barricade looks similar in terms of width to the type II barricade, but it has 1 panel instead of 2 going across horizontally.  Barricades can be made out of plastic, out of plywood, and parts can be made out of steel.  Usually the panels are plywood or plastic and the upright poles that hold it up are steel.
