WHAT IS THE DIFFERENCE BETWEEN THE WHITE AND YELLOW SPEED SIGNS?

1. Speed Limit signs with a black message on a white background are regulatory signs; while Speed Advisory signs with a black message on a yellow background are warning signs.
   
2. Regulatory signs are used to impose legal restrictions applicable to particular locations and the restrictions are not enforceable without these signs (i.e. Speed Limit signs).
   
3. Warning signs are used to call attention to hazardous conditions, actual or potential, which otherwise would not be readily apparent, (i.e. Advisory Speed signs around a curve). The established Advisory Speed at a curve is based on the safe and comfortable speed for the driver.
