Most LBM commercial motor vehicles are pulled over for a safety inspection because of improper load securement, the driver's talking on the telephone, or failure to wear the seat belt.
In all three instances, a safety patrol officer can make a visual confirmation before pulling the truck over for an inspection.
Both hands on the wheel? Not when the driver is holding a phone with one hand. Federal Motor Carrier Safety Regulations apply to commercial motor vehicles, whether short-haul, long-haul, CDL-required or non-CDL required, regardless of other state regulations. Find material on cell phone bans on NLBMDA's Regulatory Affairs' Transportation webpage, including an NLBMDA Issue Briefing: DOT Final Rule Restricting the Use of Cellular Phones by CMV Drivers.
Use the seat belt! This may seem obvious, but drivers need reminding, particularly that safety patrol officers are looking. To help ensure you don't get pulled over by making it obvious your drivers are wearing seat belts, issue orange or other hi-vis shirts or vests -- this protects drivers in the yard and at the construction site, as well as creates a visible contrast with the seat belt.
Know cargo securement tiedown requirements. The most visible cargo securement compliance or violation has to do with the use of tiedowns. The Federal Motor Carrier Safety Regulations specify the number of bands required by length of the lumber material. A good place to start is the FMCSA's Driver's Handbook on Cargo Securement: Chapter 2, General Cargo Securement Requirements, and Chapter 4: Dressed Lumber and Similar Building Material.
The two most noticed violations that will guarantee a pull over and road side inspection: 1) not complying with the rule on the number of tiedowns per length of material; and 2) not complying with the rule on tiedowns for more than two stacked bundles.
Don't know the rule on how many tiedowns. See Chapter 2 cited above as well as FMCSR 18.104.22.168, Immobilizing, and Securing Cargo: Restraining the cargo correctly.
Don't know the rule on tiedowns with more than two stacked bundles. See Chapter 4 cited above as well as FMCSR 3.2.2, Positioning and Securing Bundles.
