False |
| 5. |
Road agencies commonly use a variety of paint-based materials and thermoplastic for the centerline markings. In general, thermoplastic markings are less cost-effective as they last much lesser than paint materials. |

The standard width for each stripe of a centerline stripe is_____________ with the 4-in line more common. |
|
|
2 in to 4 in |
|
|
4 in to 6 in |
| 7. |
Edge line pavement markings define or delineate the edge of a roadway. It provides a visual reference to guide motorists and helps prevent them from drifting onto the shoulder and roadside area. |

The MUTCD prescribes several Horizontal Alignment signs to give drivers advance warning of a horizontal curve. For sections with a more than one curve in close proximity, there are three advance warning signs and they are ____________________. |

Reverse curve (W1-4) |
|
|
Winding road (W1-5) |

|
True |
|
|
False |

A rumble strip can be formed in the pavement surface by placing either grooves into the surface or strips of material above the surface according to a prescribed spacing pattern. A vehicle passing over the rumble strips produces noise and vibration and alerts the driver to a potentially hazardous situation. |
