Trucks operate differently than other vehicles due to their massive size and weight. When driving alongside a truck, there is a risk of being crushed if the truck loses control or needs to change lanes quickly. Trucks also have large blind spots where the driver cannot see, so it is important to avoid driving in these areas. Drivers should leave enough space between their vehicle and a truck in case the truck needs to change lanes or turn, to avoid the risk of collision. When changing lanes near a truck, there is a risk of entering the truck's blind spot or the truck being unable to stop in time if it needs to.
