Remember the days when you were a child and would count the number of signs on those long road trips? Well now you can literally wear all your favorite road signs right on the comfort of your wrist, with cufflinks from this Road Sign Cufflinks section. According to the Massachusetts Driving Brochure, "stop" and "yield" signs are red. Road work signs are yellow. Their function is to inform you that crews are out doing road repair on your street. Regulation signs are usually white. When you see an encircled red arrow through one of these signs, it means whatever activity the line crosses out is forbidden. Yellow signs warn. They may inform you that a road is slippery when wet, or that a school zone is nearby. That tells you to look out for schoolchildren and their parents walking across the street just before and right after school hours. In the case of the "slippery when wet" sign, you should slow down and take extra care when it's raining or snowing. Whichever your favorite sign is, you are sure to find remnants of your favorite sign right here within these pages.
