Yes they are. A bicycle is considered a "vehicle" and subject to the same laws as motor vehicles. If you did not know that check out the CA vehicle Code through the DMV.

Bike trails (just as the San Diego Creek trail, Mountain to Sea or Irvine Regional Trail) ARE public roads or at least trails and they are many rules and regulations that govern use. Again if you check city ordinances, use of bike trails are generally posted. Right of way always goes to a pedestrian over a cyclist. Keep that in mind. If you don't like it, always ride on the street. Personally I like using a bike trail, keeping myself away from cars but I know, a walker, jogger etc has all rights over me. If I pass, I need to make sure 1) it's safe and 2) the walker, jogger is aware.

Something many of you may not be aware of but most club riders know... it may be OK for you to pass without saying a word, but its not OK for the walker/jogger. They complain. They complain alot! I don't think there is one major club in OC that has not be contacted by some City (Irvine especially) about complaints. I guess if you plan on being rude, and not calling out, don't wear a club kit and get your club in trouble!!!

Personally I have seen riders, two abreast, buzz right pass a woman with a stroller or parents with small kids. Several years ago an elderly woman was killed (it was an accident though) when two riders came up on her fast as she entered the multi-use trail. If they had called out she made have waited before entering.

Remember, we call it a bike trail but it is really a multi-use trail. You can run across horses, walkers, joggers, skaters and other riders, recreational and serious. A trail is the least efficient way to get from point A to B and one should alway ride with caution. I think with people and calling out, they so seldom hear it anymore, it startles them. Let's get them back in the habit of hearing us riders coming up.

And riders, no excuse not to call out to other riders. Just yesterday I almost nailed some one when I moved to my left and didn't know someone was passing. He almost flew off into a ditch. What a dork for not calling out!

And dirt riders... some thing. Call out! And remember its horses first (always always stop and allow the equestrian to wave you by), hikers and then riders who have the right of way and its uphill riders not downhill who have the right. If you are blasting downhill, it's your duty to pull over and alloow the uphill rider to pass first.

Again - GET OFF MY LAWN! and stay safe out there!
