Unit 04, Lesson 03 - Construction Signs and Mileposts
Construction Signs
There are three types of barricades. Those with one or two bars indicate a hazard in the road and will indicate the direction you should go to avoid the hazard. Barricades with three bars indicate the road is closed, and the stripes indicate the direction you should go.

Drivers must comply with official hand signal devices (flags, stop-and-go paddles, etc.) displayed by adult flag persons wearing appropriate uniforms and badges or insignia.
Here are six additional construction signs you may see while driving along our streets and highways.

Mileposts
Mileposts are erected along most state highways to assist you in pinpointing your location, to provide a means of identifying the location of accidents and other emergency situations and to aid in highway maintenance and servicing. Zero mileage begins at the south and west state boundaries or at junctions where routes begin. The mileage numbers increase as you travel north and east.
