MUTCD Section 2C.40 Vehicular Traffic Signs (W8-6, W11-1, W11-5, W11-5a, W11-8, W11-10, W11-11, W11-12p, W11-14)
Option: Vehicular Traffic (W8-6, W11-1, W11-5, W11-5a, W11-8, W11-10, W11-11, W11-12p, W11-14) signs (see Figure 2C-9) may be used to alert road users to locations where unexpected entries into the roadway by trucks, bicyclists, farm vehicles, emergency vehicles, golf carts, horse-drawn vehicles, or other vehicles might occur. The TRUCK CROSSING (W8-6) word message sign may be used as an alternate to the Truck Crossing symbol (W11-10) sign.
Support: These locations might be relatively confined or might occur randomly over a segment of roadway.
Guidance: Vehicular Traffic signs should be used only at locations where the road user's sight distance is restricted, or the condition, activity, or entering traffic would be unexpected.
If the condition or activity is seasonal or temporary, the Vehicular Traffic sign should be removed or covered when the condition or activity does not exist.
Option: Supplemental plaques (see Section 2C.43) with legends such as AHEAD, XX METERS (XX FEET), NEXT XX km (NEXT XX MILES), or SHARE THE ROAD may be mounted below Vehicular Traffic signs to provide advance notice to road users of unexpected entries.
Standard: The Emergency Vehicle (W11-8) sign with the EMERGENCY SIGNAL AHEAD (W11-12p) supplemental plaque (see Figure 2C-9) shall be placed in advance of all emergency-vehicle traffic control signals (see Chapter 4F).
Option: The Emergency Vehicle (W11-8) sign, or a word message sign indicating the type of emergency vehicle (such as rescue squad), may be used in advance of the emergency vehicle station when no emergency-vehicle traffic control signal is present.
