I am getting a little pissed off at bicyclists riding on the sidewalk when there is a perfectly good road to ride on. Mostly they are teens who are too inconsiderate to signal when they are coming up on you and/or to slow down when they are passing you. I know from plenty of experience that bikes can come up on you with no warning at all and scare the piss out of you when you notice they are right behind or right next to you.
On all the dual-use trails in the area there are signs explicitly restricting bicycle speed limits and requiring that you use a bell or horn to alert those who you are approaching from the rear. There are no laws in Virginia that say one cannot ride a bicycle on a sidewalk but they do require that you “give an audible signal before passing.” Unfortunately there are no signs posted on the sidewalks that make people aware of the regulation. Perhaps the state thinks that riders will be considerate enough…right!
