Legal Limits And Road Safety

Road safety depends heavily on knowing how much trucks weigh. Trucks must follow certain weight limits. These limits protect bridges and roads from damage.

They also make sure trucks can stop safely. Every country has rules for truck weights. Not following these rules can lead to accidents.

National And International Regulations

Trucks must not be too heavy. Countries set their own weight limits. In the USA, the legal weight for an 18-wheeler is approximately 80,000 pounds.

The European Union also has strict rules. Trucks in Europe must usually weigh less than 40 tonnes. Other countries follow similar regulations. Limits can change for different roads or areas.

International rules matter too. Trucks that cross borders must respect weight limits in all countries. Special permits are needed for heavy loads. This makes sure roads stay safe for everyone.

Implications Of Overloading

Overloading a truck is bad. It can cause many problems:

  • Damage to infrastructure: Heavy trucks can break roads and bridges.
  • Risk of accidents: Overloaded trucks are harder to control. They take longer to stop. This can lead to crashes.
