I would add that there's a truck driver shortage in the US which means that less than stellar drivers with a clean CDL can get a job and keep a job easier than ever. This can also mean that some of the OTR drivers might not be the traditional "knights of the highways" we've come to expect. Some might drive more aggressively than in the past. Some might have recently come from countries where driving customs differ from the US/Canada and even Mexico.
I write this as one who has great respect for OTR drivers and prefer driving amidst trucks at night than cars by day. Truckers are often more disciplined and predictable than car drivers (IMHO).
By the same token try to give the OTR drivers a break by maintaining an even speed, using the left lane for passing only, and be aware of left lane truck prohibitions on some roads which confines trucks to the two other lanes. They're working long hours, away from family, and stressed.
