Not on mine. The length of the breakaway cable will activate the brake on the toad before the safety chains become into play. I'm sure others will agree. The safety chains are the secondary attachment to the TV in order to maintain control until you can safely stop without damage to the toad or TV.
If you had an event like you describe, having the to bar dig into the road -- it could be disasterous.
In addition, the breakaway system will activate without any action by the driver. In your case, how will the solenoid by activated?
