The one passing me wasn't, but I didn't know its wheel base or if it was a double until it cleared me.
If you want to drive or ride safely you should be aware of your surroundings. Trucks don't just sneak up on you, they are visible and audible for a long time before they pass you.
Head check and/or use mirrors.
The trouble with b-doubles is your view of the second trailer is almost entirely obscured by the prime mover and lead trailer.
It woudl be very easy for a fatigued rider to forget about the possibility of a second trailer and swing out behind the first on an assumption...
