Opt Level 1.25 - System Update

Explanation
The statement is false because driver macro replies are used to update customers with arrival and departure information.

Explanation
When a unit is sent to a tank wash but the trailer is not dropped, the event code "WSH" should be used. This code indicates that the unit has been sent for a tank wash, but the trailer has not been detached from the unit.

Explanation
The statement is false because BMT (Begin Empty) is not a billable event code.

Explanation
The statement suggests that DRL (Drop Loaded) is a billable event code. This means that whenever a drop loaded event occurs, it will incur a cost or be included in the billing process. Therefore, the answer "True" indicates that the statement is correct.

Explanation
When a cancellation occurs while the truck has arrived or is in route to pick up the load, several actions should be taken. First, the load destination should be changed to mirror the origin to ensure accurate recordkeeping. Second, the commodity should be changed to "Cancellation" to indicate the reason for the cancellation. Third, the scheduled delivery time should be adjusted to mirror the scheduled pickup time to maintain consistency in the timeline. Fourth, the Stops Detail should be reviewed to ensure that the delivery arrival time is one minute past the pickup departure time. Fifth, the unit empty miles should be updated to reflect the driver's next point of assignment. Sixth, a billing note should be added to bill the customer for the cancellation and to ensure the driver is paid accordingly. Finally, any correspondence regarding the cancellation should be forwarded to Customer Service to be placed in Onbase for documentation purposes.

Explanation
If a load cancels before the unit starts loading, it is best to de-assign the load and cancel it from the system. This ensures that the unit does not waste time and resources preparing for a load that will not be completed. By de-assigning and canceling the load, the unit can move on to other tasks or potentially be assigned a new load that is ready to be transported.

Explanation
The event code TRKBKD should be used for truck or trailer breakdowns when the unit is under a load.

Explanation
When a unit breaks down and the load needs to be repowered, the split in the trip should be inserted AFTER TRKBKD. This means that the trip will be split after the unit has tripped due to the breakdown. Splitting the trip after TRKBKD allows for the load to be repowered without affecting the unit that has already tripped.

Explanation
The event codes TRKBKD and HCT should be used when a trailer is leaking and the load needs to be trans-loaded. These codes likely indicate that the trailer has a tracking board leak (TRKBKD) and that a hazardous cargo transfer (HCT) is necessary to move the load to a different container or vehicle.

Explanation
The intermodal switch is necessary for all intermodal loads that involve ISO containers with chassis. This switch allows for the smooth transfer of the container from one mode of transportation to another, such as from a truck to a train or ship. Without the intermodal switch, it would be difficult to transfer the container between different modes of transportation efficiently. Therefore, it is true that using the intermodal switch is mandatory for all intermodal loads involving ISO containers with chassis.
