The biggest reasons commercial trucks are more dangerous than other vehicles include:
Trucks weigh more, which means that when they crash into a smaller vehicle, it will result in much more severe injuries.
Trucks make wider turns than smaller cars which causes them to sometimes sweep other vehicles or crush vehicles located alongside them.
Trucks have more tire blowouts, which causes the truck driver to lose control of the vehicle. The debris from tire blowouts is also dangerous to other drivers.
Trucks take longer to stop, and when drivers are not careful while stopping, they may crash into vehicles in front of them.
These are just a few of the reasons trucks are more dangerous than other vehicles on the road.
