If you drive your truck on the interstate highway regularly in commercial capacity – that you are carrying passengers or load of more than 10,000lbs, you are required to obtain a Department of Transportation (DOT) number.

While not everyone knows about obtaining a DOT number in the States, it is mandatory for commercial drivers of all types. 

Your motor carrier authority usually issues the DOT number. The purpose of a DOT number is to make sure that your truck (vehicle) is registered with the motor vehicle authority and licensed to drive on the highway.

Let’s learn if Los Angeles vehicles need to obtain a DOT number or not.

Do Los Angeles Vehicles Require a DOT Number?

Yes, any vehicle in Los Angeles that carries more than a certain amount of weight or more than a certain quantity of passengers needs a DOT number. The California state motor vehicle authority will be liable for providing the DOT number to these vehicles.

Who Will Need a DOT Number?

Over 33 states for interstate commerce require a USDOT number. The eligibility criteria for getting the DOT number is based on the following requirements.

  • The vehicles which need a DOT number should carry more than 10,000 lbs of weight. 
  • They are responsible for transporting 9 passengers or more in return for compensation, i.e., the local public transportation system in a carpooling app.
  • The vehicle that carries haphazard materials also needs a DOT number. If these materials fall on the road, they can cause damage.

For all these conditions, the driving authority – the company that owns these trucks – needs to register with the Federal Motor Carrier Safety Administration (FMCSA). 

The vehicle is also recommended to display a DOT number while it is active on the job. This condition is only applicable to commercial vehicles. Companies that don’t have their transport and hire third-party transport services to get their goods delivered should also abide by the government rules.

Moreover, you also need to register a business if you still haven’t done so. The cost can be between $70 and $500.

According to the State of California, trucks can only get permission for driving on the interstate highway. 

The authority has provided clear instructions on how it weighs various trucks for providing the DOT license.

Let’s learn about these DOT licensing requirements.

  • The person having a driver’s license should have at least 21 years of age. In some countries, the limit is 18 years of age.
