That depends... are you going to keep your speed at 10 mph or lower? Or, what are your options if it slides off the back of your truck into the lane of traffic... and someone runs into it?
I think your insurance agent would have a lot to say to you, starting with... your carelessness voided your insurance for this occasion!!!
Think it through before you make a decision... decide on the side of safety, even though none of the above scenarios are likely to occur.
