 They have to know how long they've been driving, how long they've been resting, how many miles they've gone. And that is no longer a paper log, which it used to be. You used to have to enter that, and you would be checked at truck stops. But now it's all digital. So there's no reason in the world we can't have an electronic scanner that tells you what that truck is, what it's carrying, how long it's been on the road.
