Hello. You may already know that the biggest and heaviest vehicles allowed on our roads are called big trucks. Even a child knows that trucks are used to carry stuff from one place to another.

You probably wont know that the word truck is derived from the Greek word "Trochos" meaning "wheel".

Not surprisingly trucks have a huge effect on the condition of our roads. And because of their size it means roads get damaged. In the majority of countries with good quality roads trucks aren't allowed to carry more than 50,000 kg.

Unfortunately trucks also pollute our atmosphere . A truck is legally heavy duty if it weighs more than 8 and a half thousand pounds.

You probably don't know that a truck is apparently not allowed to legally emit the equivalent of around 12 cars. But often times when tested some trucks are emitting 10 times that amount.

If you live in the city or the suburb then you probably already know that these are the places where trucks are the most dangerous. Because they are so large and the traffic is so close they are dangerous to people in cars.

A worrying statistic shows that when it comes to accidents between a car and a big truck over 90%+ the people in the car die. This is why a lot of people are scared to share the roads with trucks.

Because of their size trucks cause air turbulence that can either suck a car in under it's wheels or push the car away. Either of these could could cause a very serious accident.

However it's nice to know that even though these huge beasts can be so dangerous the drivers are often trained to a very high standard and according to some statistics show that commercial truck drivers are some of the safest drivers on the roads.

And what's even better is that compared to ten years ago, accidents involving big trucks have decreased over twenty percent!
