Signing Guidelines

A REDUCED SPEED AHEAD (W3-5) should be installed in advance of the change of pavement surface area and speed limit. PAVEMENT ENDS (W8-3), NO CENTER LINE (W8-12), and a ROUGH ROAD (W8-8) or LOOSE GRAVEL (W8-7) should also be installed in advance of the change in pavement surface. Any or all three of these signs could include a NEXT X MILES (W7-3aP) plaque. A SPEED LIMIT (R2-1) sign should be installed at the point of the speed limit change as established by a Transportation Commission Minute Order.

The NO CENTER LINE (W8-12), ROUGH ROAD (W8-8) or LOOSE GRAVEL (W8-7) and SPEED LIMIT (R2-1) sign should be repeated every two miles or after major intersections along the route. Engineering judgement can be used to alter the spacing when necessary.
