When sharing the road with a large vehicle, such as an 80,000-lb truck,?

Here are some things you need to do when you share the road with a large vehicle : 
- When passing a truck, be sure to pass it through the left side
- Never stop abruptly. Large vehicles tend to need greater distance to stop than cars
- Don't try to bypass the large vehicles when they're trying to make a turn
- Try to stay away from trucks on windy days
- Do not swerve in and out in front of large vehicles

hope this helps
