Blind spots are everywhere!
Even your car has blind spots. The number of blind spots in a big rig is insane. The passenger side of a semi has far more blind spots than the drivers side, so use proper truck safety techniques and try to always pass an 18 wheeler on the left. Hurry up and get ahead of the truck…don’t dilly dally around. The trucker may not know you’re even there, and God forbid the driver makes a quick lane change or swerves to avoid road debris, etc. Here is a diagram showing the most dangerous areas to be. Stay out of the no zone!
