It falls under the 'Supporting Documents' doctrine. They are entitled to see all your expense receipts for food/fuel/whatever. They are also entitled to see your payroll/settlement paychecks too.

 

97% of trucks on the road belong to fleets with 20 or less trucks.

Werner has reduced their fleet by 250 trucks in the last year.

If you have ever been involved in the sales end of a business then you will have sat through meetings about not only the volume of sales but the size of your companies' piece of the pie.

You can say tin foil hat all you want but if you don't think part of the conversation is how to increase the size of the company's "piece of the pie" you're ignorant or nieve. Supporting legislation to make business more expensive for your competition is pretty is easy to see.

 

In case you are wondering?
What are the categories of supporting documents?
PreviousNext
Given the diversity of the industry, FMCSA has identified five categories of supporting documents:

• Bills of lading, itineraries, schedules, or equivalent documents that show the starting and ending location for each trip;
• Dispatch records, trip records, or equivalent documents;
• Expense receipts related to “on-duty/not driving” periods (meals, lodging, fuel, etc.);
• Fleet management system communication records;
• Payroll records, settlement sheets, or equivalent documents showing payment to a driver.

Drivers using paper RODS must also keep toll receipts – which do not count toward the eight-document cap.

Plenty more where that came from

Not until December 18, 2017.

§395.11 Supporting documents.
(a) Effective date. This section takes effect December 18, 2017.

This part is new and was previously not required in the U.S., and will not be required until the effective date as posted above. Roadside inspections in Canada have been subject to a similar provision for years.

(g) Supporting documents at roadside. (1) Upon request during a roadside inspection, a driver must make available to an authorized Federal, State, or local official for the official's review any supporting document in the driver's possession.

(2) A driver need not produce a supporting document under paragraph (g)(1) of this section in a format other than the format in which the driver possesses it.

Lol. Thermal imaging came to my mind first when I read the title.

Drove through Grass Lake one day and one of my buddy's trains was around back with a service truck. When I called him to see what was up, he said the IR camera showed one wheel cool, so they pulled his driver around for inspection. The service truck was replacing a slack adjuster.

 

The way the regulation is worded would seem to exclude lodging and most meal receipts as they are typically generated during off-duty time only. A simple way to minimize the impact of the recordkeeping and by-pass the regulation somewhat will be for some companies to issue drivers a daily subsistence expense to be spent at their discretion (as is done with some carriers--most often oilfield--here). The company includes it on the driver's payroll and that record is retained and available according to the regulation. If the driver only spends it during off-duty periods no receipts are required.

(c) Supporting document retention. (1) Subject to paragraph (d) of this section, a motor carrier must retain each supporting document generated or received in the normal course of business in the following categories for each of its drivers for every 24-hour period to verify on-duty not driving time in accordance with §395.8(k):

(i) Each bill of lading, itinerary, schedule, or equivalent document that indicates the origin and destination of each trip;

(ii) Each dispatch record, trip record, or equivalent document;

(iii) Each expense receipt related to any on-duty not driving time;

(iv) Each electronic mobile communication record, reflecting communications transmitted through a fleet management system; and

(v) Each payroll record, settlement sheet, or equivalent document that indicates payment to a driver.
