First off this is my first post and I am very new to the world of biking, so bear with me. =)

Just today I was riding to the store in my town. I signaled a right turn and I totally lost control and lost balance and skid myself across the pavement. Besides having my wind knocked out and a couple nasty brush burns on my arms, I am alright. Thankfully there were 3 guys on motorcycles behind me who stopped and made sure i was alright.

It was on a very busy street and I try to keep up with the flow of traffic as much as possible. How can I take my hand off under high speeds and not lose control? Any tips or advice would be greatly appreciated.
