The size and weight difference between commercial trucks and passenger vehicles is significant and can have serious implications in the event of an accident. Commercial trucks, also known as tractor-trailers or semi-trucks, are significantly larger and heavier than passenger vehicles. The average commercial truck can weigh up to 80,000 pounds, while the average passenger vehicle weighs around 4,000 pounds.

In addition to being heavier, commercial trucks are also much larger in size. They are typically 70 to 80 feet in length and up to 13.5 feet in height, compared to the average passenger vehicle which is about 14 feet in length and 6 feet in height. The larger size and weight of commercial trucks means that they require more space to maneuver and stop, and they also have larger blind spots that can make it difficult for drivers to see smaller vehicles.

The size and weight difference between commercial trucks and passenger vehicles can increase the severity of injuries and damage in the event of an accident. In a collision between a commercial truck and a passenger vehicle, the passenger vehicle is likely to sustain significantly more damage and the occupants are at a higher risk of serious injury or death. This is why it's important for drivers of passenger vehicles to be cautious and aware when sharing the road with commercial trucks, and to give them plenty of space to maneuver.
