Pretrip and postrip inspection

Both are required although you only need to log on duty for pre trip.
Post trip must be flagged.

 

i don't believe you are required to log both as long as you are the only person driving the truck from day to day.

 

Pre trip must be logged on duty and post trip can be flagged. Time clock punchers within 100 air miles don't need a log .
Canada has different rules.

 

Any work must be logged. So doing the pre trip is on duty. Post trip is just a paper work requirement. If you actually inspect, you would log as on duty. Otherwise you flag it on paper logs showing you did it but tookess than 8 minutes to do.
If you are on elogs, just log as on duty for both for however long it takes.

 

First off, "flagging" IS logging, but for events that are less than 15 minutes long (on paper logs).

Guidance for § 395.8: Driver's record of duty status.

Question 1: How should a change of duty status for a short period of time be shown on the driver’s record of duty status?

Guidance: Short periods of time (less than 15 minutes) may be identified by drawing a line from the appropriate on-duty (not driving) or driving line to the remarks section and entering the amount of time, such as “6 minutes,” and the geographic location of the duty status change.

Regulations Section​

Second, there is no requirement to log a pre-trip.

§396.13 Driver inspection.

Before driving a motor vehicle, the driver shall:

(a) Be satisfied that the motor vehicle is in safe operating condition;

(b) Review the last driver vehicle inspection report; and

(c) Sign the report, only if defects or deficiencies were noted by the driver who prepared the report, to acknowledge that the driver has reviewed it and that there is a certification that the required repairs have been performed. The signature requirement does not apply to listed defects on a towed unit which is no longer part of the vehicle combination.

eCFR — Code of Federal Regulations​

Third, there is a requirement to do a post trip, but only produce a report if defects are found.

§396.11 Driver vehicle inspection report(s).

a) Equipment provided by motor carrier. (1) Report required. Every motor carrier shall require its drivers to report, and every driver shall prepare a report in writing at the completion of each day's work on each vehicle operated, except for intermodal equipment tendered by an intermodal equipment provider. The report shall cover at least the following parts and accessories:

2) Report content. (i) The report must identify the vehicle and list any defect or deficiency discovered by or reported to the driver which would affect the safety of operation of the vehicle or result in its mechanical breakdown. If a driver operates more than one vehicle during the day, a report must be prepared for each vehicle operated. The driver of a passenger-carrying CMV subject to this regulation must prepare and submit a report even if no defect or deficiency is discovered by or reported to the driver; the drivers of all other commercial motor vehicles are not required to prepare or submit a report if no defect or deficiency is discovered by or reported to the driver.

eCFR — Code of Federal Regulations​

 

And, yes, the Canadian rules are different; only one written and logged inspection per 24 hours while being operated is required.

NSC Standard 13: Trip Inspections Part 1 – General Requirements

(4) Required inspections (when operated)
(a) Trucks, tractors and trailers shall be inspected in accordance with Schedule 1 every 24 hours.

While there is no requirement to do a pre trip, if one is done it has to be logged. As per the fmcsa:
On-duty time means all time from the time a driver begins to work or is required to be in readiness to work until the time the driver is relieved from work and all responsibility for performing work. On-duty time shall include:
(2) All time inspecting, servicing, or conditioning any commercial motor vehicle at any time;

So yes a pre trip must me logged, if done. I think what you meant is there is no requirement to DO a pre trip (and your links support that). The thing is, while a pre trip isn't specified, I have a hard time coming up with a way to "Be satisfied that the motor vehicle is in safe operating condition". Well trust someone else to do the inspection for you I guess, but that's about all. Heck I would not trust a new vehicle coming out of the factory to pass inspection....

 

I am on the FMCSA website a good bit every day as well as looking around on the Federal Register. I came across THIS FMCSA news release and found it odd in regard to how the rules are written. Notably this paragraph! (Failing to require that drivers conduct pre- and post-trip vehicle inspections and submit reports of safety defects to the company in order to make repairs.) This is why I sometimes want to yank my hair out. It seems that daily I am finding example after example of gobbledygook or outright contradictions in 49CFR.
