Why these tools
The hours of service rules decide when a driver has to stop, and the four clocks run at the same time, which is where most violations come from: one clock runs out while the driver is watching another. The knowledge tests are the first step toward a CDL and every endorsement, and they are written from the same model manual in every state.
