The is the standard for traffic control devices on roads open to public travel. See Section 2C.33 for warning signs and plaques to be used for motorcyclist. Conditions that these signs came be used to mitigate include:

Some signs and plaques have special word message signs for situations where roadway conditions make it necessary to provide road users with additional warning information and where a standard message is not provided in the . As an example, these are the STEEL GRID DECK (W8-V1), EXPANSION JOINTS (W8-V2), and OPEN JOINTS ON BRIDGE (W8-V3) warning signs.

The need for smooth riding surfaces for motorcyclists should be provided, or advance warning notification given whenever roadways surfaces are disturbed. When plans call for milled or grooved pavement, the specifications should be reviewed so that the resulting surface is fine enough to prevent motorcycles tires from being captured or redirected at high speed.

The special needs and control of motorcyclists should also be considered through a temporary traffic control zone.

Pavement scarring of the roadway exceeding 1/8-inch should be repaired to prevent deterioration of the pavement surface and to provide a smooth surface for motorcyclists.

Metal coverings provide a challenge to motorcyclists when they traverse them unexpectedly in the roadway.

The design of the crossover should accommodate all vehicular traffic including motorcycles, trucks, and buses.
