Wouldn’t you have about the same reaction time as if the truck was braking tho? I mean, the momentum will carry the log in the direction the truck was going until it dissipates, which is kinda the same as braking.

I mean, that situation would obviously be dangerous because you don’t wanna stop on a freeway for obvious reasons, but still, if you adhered to common safety rules, you should be okay in that situation, no?
