I have a safety triangle on the trunk-bag... a bright yellow flagpole with a bright orange flag about 7' off the ground, and a Mars II bright blinking red tail light on the flagpole. If you don't see me, you're not looking... not to mention that the two wheels up front are also pretty easy to see from behind... it is not like I'm as narrow as a bike. I also flash a bright light on the front of my trike to be seen by oncoming traffic. And the trike itself is a bright yellow/orange frame.

Knowing how to ride and command a lane is more important... you can ride to be seen as well. Don't ride next to a line of parked cars (DUH) or you'll get doored. Avoid routes with blind corners, especially ones that that you will be climbing on. The car coming around WILL! make a right turn and cut you off... eye contact is all the rave!

On a trike, or any bike, you are traffic and unfortunately, when an acident happens it is catogorized as just that, an accident. Unfortunately, you are far more vulnerable than the other guy whether it's a car or motorcycle. The laws are changing but ever so slowly. Right now, if someone hits you it's an "*oops*; my insurance will try to take care of you, have a good life.".

On the plus side, people tour on cycles every day. Visibility, planning, and proper attension to road manners will get you a long way. ...then again, you could step off the curb to get your mail and get mowed over by a drunk... so what's the real risk.
