Okay, imagine a big dumper truck. It is really strong and helps carry heavy stuff like dirt or rocks. But, some streets in the city are narrow and made for smaller cars, not big trucks.
1. Size: Dumper trucks are really big! They can be much wider than a car, so they might get stuck or knock over things on the side of the road.
2. Weight: These trucks are heavy because they carry a lot. If they drive on a road that’s not strong enough, it might get damaged.
3. Turns: When big trucks make turns, they need more space. In the city, some turns are too tight for them to go around safely.
4. Traffic: In busy cities, there are many cars and people. It’s harder for big trucks to drive safely without getting in the way.
So, dumper trucks usually drive on bigger roads and highways where they have enough space to move around safely and not cause problems.
