Jerking upon opening garage initially

Lately, when I go to open my garage door, it jerks and then stops. I have to then close it and start again to open it. What could cause it to do this?

The rollers on the side are binding in the tracks. Track bent? Roller bent?

Check the rollers on each side, make sure the are not crooked, binding, or other wise. Often the tracks that they run in can get a little tweeted, and this can cause issues, especially where the two pieces meet. Could be binding there.

If your door still has a manual lock on it, sometimes the bar can catch on the track as it passes through the curve.
