When sharing the road with trucks it is extremely important to practice proper passing behavior. We've already covered most things to remember for proper passing. To recap:
This clip shows an extremely dangerous improper passing scenario. Notice the black pickup truck speeding up from behind and passing the truck in the passenger's side right no-zone blind spot. In the forward roadway view, you can see that the traffic ahead is stopped. The pickup changes lanes in front of the truck, directly into the front no-zone, and then stops quickly. The truck driver has to slam on his brakes, only narrowly avoiding smashing into the back of the pickup.
This clip illustrates pretty much everything you should never do when passing a truck. The pickup recklessly speeds up behind the truck, passes on the passenger's side of the truck, cuts dangerously close in front of the truck and stops suddenly. All these elements combined create an incredibly dangerous situation that could have ended in tragedy if not for the truck driver's quick reaction. Please do not drive recklessly when sharing the road with trucks. Remember to exercise caution when passing trucks on the road. It could save your life and the lives of your passengers.
This clip provides an example of proper passing behavior when sharing the road with trucks. Notice the red pickup approaching from behind in the driver's side blind spot. This vehicle is not lingering, but moving at a nice, steady pace. They pass safely on the left driver's side of the truck. They also wait until they are far enough ahead of the truck to safely change lanes. This is precisely the sort of driving behavior you should aim for every time you pass a truck on the road.
