When passing by or being passed by trucks and other large vehicles on the road, you must be aware of wind blast. A large amount of wind is pushed to the side of these vehicles at high speed, and it can potentially push your motorcycle from side to side or momentarily cause you to lose some stability. If you’re aware of the potential for windblast and anticipate it, you’ll reduce the potential for windlblast to create a dangerous situation.
I try to pass trucks or larger vehicles quickly and move to the far side of the lane to be as far away as possible form the truck. Just as I am about to go through potential windblast zones, I lean a bit towards the truck. That way, when I’m pushed the opposite way by the wind blast its already being corrected. 18 wheelers with large flat fronts tend to make the most blast at the front of the truck, but the wheels back on the trailer can also create it too. I’ve also found truck can sometimes give of turbulence in weird spots, so generally when passing a truck, no matter where you are in relation to it, mind the potential for wind and turbulence.
