Long ago, your feet, or horses, were the only way to travel the roads and highways. However, animals are no longer used to get around on our public roads. Modernly, there are engine-powered vehicles, human-powered vehicles, and even batteries. Since the last 2022 Legislative Session. California Vehicle Code Section 415 (a) A defines a “Motor vehicle” as a vehicle that is a “self-propelled” mechanical vehicle.

In California, the law to drive motorized vehicles is different than driving actual motor vehicles since you do not need a license or registration for a motorized vehicle, unlike a moped that travels more than 30 mph. Although this article is more about land vehicle types, we have disclosed everything you need to know about all types of vehicles, not just motorized conveyances.

Our personal injury attorneys have compiled some information to help readers get acquainted with the laws and clear up the doubts of many who are confused.

How do we classify types of vehicles? Importance of vehicle categories

Classifying types of vehicles is essential for several reasons, including regulation, standardization, market access, and safety considerations. For example, minivans are designed with kids in mind, so generally, certification will be based on a combination of practical considerations dealing with child passengers, such as easy access and egress. And not all vehicles have doors, like snowmobiles or a convertible Jeep Wrangler with a removable bikini top or fiberglass roof. Some come with a hatchback, and others come equipped with a trunk. Some are motorcycles powered by gas motors, some diesel; others could include an electric sedan or hydrogen-powered Tesla coupe. It can be in the shape of a box, a wedge, or a frame with an engine and tires. Last, it could even include a rocket-powered spacecraft or sea vessel, so they aren’t always equipped with brakes as another comparison!

Here are some key points regarding the importance of vehicle categorization:

Regulation and Compliance

Vehicle categories provide a framework for establishing regulations and standards specific to different types of vehicles. Governments and regulatory bodies use vehicle classifications to set safety, emissions, and performance standards, ensuring compliance and promoting vehicle safety and environmental sustainability.

Standardization and Interoperability

Vehicle categorization allows for the standardization of technical specifications, components, and systems. Common classifications facilitate harmonization efforts, enabling manufacturers to design vehicles that meet standardized requirements across different markets. This promotes interoperability and compatibility between vehicles and their components, simplifying manufacturing, maintenance, and repair processes.

Market Access and Trade

Vehicle categories play a significant role in market access and trade agreements. Common classification systems facilitate international trade by ensuring mutual recognition of vehicles and components, reducing barriers to entry, and enabling manufacturers to access global markets. Harmonized classifications also enhance market transparency, enabling consumers to make informed decisions.

Safety Considerations

Different vehicle types have unique safety considerations. Categorizing vehicles helps define safety standards specific to each type, addressing factors such as vehicle size, weight, passenger capacity, and intended use. This allows for developing and implementing appropriate safety regulations and technologies to mitigate risks associated with different vehicle categories.

Data Collection and Analysis

Vehicle categorization allows for effective data collection and analysis. Governments, researchers, and industry stakeholders use vehicle classifications to gather information on vehicle sales, usage patterns, energy consumption, emissions, and safety performance. This data informs policy-making, research, and the development of future automotive technologies.

Vehicle categorization is vital for regulatory compliance, standardization, market access, safety regulations, and data analysis. It enables the automotive industry to operate efficiently, ensures consumer safety, and promotes sustainable transportation practices.

History of internal combustion engine and electric car

Here is a summary of the key milestones:

  1. Pyréolophore (1807): Created by Nicéphore Niépce, the Pyréolophore is considered the first internal combustion engine. It utilized a mixture of inflammable liquid and air to generate controlled explosions.
  2. François Isaac de Rivaz (1828): Rivaz, a Swiss architect, is credited with inventing the world’s first internal combustion engine automobile. His vehicle, known as the Rivaz car, utilized a hydrogen-oxygen-fueled internal combustion engine.
  3. Gustave Trouvé (1881): Gustave Trouvé, a French electric engineer, invented one of the early electric cars. His creation was an electric tricycle, considered to be the first electric car in history. Trouvé later continued to make advancements in electric propulsion systems.

These pioneering inventions laid the foundation for the subsequent advancements and innovations in the automotive industry. The internal combustion engine became the dominant power source for automobiles for many years, while electric cars experienced intermittent development and refinement, ultimately leading to their resurgence in recent times as a sustainable and environmentally friendly transportation option.

What are the three categories of a vehicle?

Vehicles can be broadly categorized into three main types:

Land Vehicles

This category includes vehicles designed to operate on land surfaces and those used in the family car world, not just the typical two-door car. It encompasses various modes of transportation, such as a car or a pickup truck. Land vehicles also include all-terrain vehicles, ATVs, motorcycles, buses, bicycles, semi-trailers, and trains. In the United States, the Federal Highway Administration (FHWA) and the Environmental Protection Agency (EPA) use different classification systems to categorize trucks based on their weight, fuel economy, and whether they transport people, not just goods or products.

Here is a breakdown of these classifications most humans will understand:

FHWA Classification Definition of These Motor Vehicles

  • Light-Duty Trucks (Class 1-4): This classification includes trucks with a Gross Vehicle Weight Rating (GVWR) ranging from 0 to 14,000 pounds. It includes pickup trucks, vans, or a sport utility vehicle. (SUV.)
  • Medium-Duty Trucks: This classification includes trucks with a GVWR between 14,001 and 26,000 pounds. It includes delivery trucks, box trucks, and small buses.
  • Heavy-Duty Trucks: This classification includes trucks with a GVWR exceeding 26,000 pounds. It includes tractor-trailers, large buses, and other commercial vehicles. Notably, the European Union, Russia, and other countries have their own classification systems, making trade more difficult for some cargo platforms.

EPA Classification of These Engine-Powered Vehicles

The Environmental Protection Agency categorizes vehicles based on their emissions evaluation and energy savings potential, primarily focusing on vehicle weight.

  • Light-Duty Vehicles: This category includes passenger cars, SUVs, and light-duty trucks with a Gross Vehicle Weight Rating (GVWR) of 8,500 pounds or less.
  • Heavy-Duty Vehicles: This category includes trucks with a GVWR exceeding 8,500 pounds. It encompasses a wide range of commercial trucks, including medium-duty and heavy-duty trucks.

It’s important to note that the specific weight thresholds and criteria used for classification may vary or be subject to updates by the FHWA and EPA. These classifications help establish regulations, standards, and guidelines related to vehicle safety, emissions control, and fuel efficiency.

Passenger Cars

Passenger vehicles, also commonly referred to as a car or automobiles, are motor vehicles designed primarily for the transportation of people.

Self-Propelled Mechanical Vehicle

They’re typically a four-wheeled, engine-powered vehicle that transports people. Depending on their size and configuration, they are often equipped with seating for one to several passengers. Passenger cars are primarily intended for personal use, commuting, family transportation, or recreational purposes.

Characteristics of passenger cars include:

  1. Seating Capacity: Passenger cars are designed to carry a limited number of passengers, typically ranging from one to nine occupants, including the driver.
  2. Body Style: Passenger cars can have various body styles, such as sedans, hatchbacks, coupes, convertibles, station wagons, or sport utility vehicles (SUVs). Each body style offers different features and design elements.
  3. Purpose: Passenger cars are primarily for personal transportation, commuting, and daily travel. They are not typically designed for carrying heavy loads or specialized purposes like commercial hauling or off-road capabilities.
  4. Features: Passenger cars are equipped with amenities and features to ensure the occupants’ comfort, safety, and convenience. These features may include air conditioning, entertainment, navigation, advanced safety technologies, and more.

Passenger cars are subject to various regulations and safety standards to ensure their roadworthiness and the safety of occupants and other road users. They are a common mode of transportation worldwide and play a significant role in the transportation infrastructure of societies.

What Does California Law Say about Motorized Scooters?

Under the California motorized scooter laws, a motorized scooter may have a seat, but that is not a defining feature of it as a scooter can be a motorized scooter if it has two wheels, handlebars, a floorboard to stand on, and a motor for powering the scooter.

Although registration with the DMV and a specialized license is not required to drive a motorized scooter, you need a regular driver’s license.

The laws for driving a motorized scooter on the road are the same as with any other vehicle, but there are certain restrictions in California:

  • Drivers should wear a US Department of Transport-approved helmet
  • Riders can only ride motorized bikes in bike lanes on roads with speed limits exceeding 25 miles per hour
  • Can not ride on sidewalks
  • No passengers allowed except a single driver on the electric scooter
  • Motorized scooter riders can’t ride over 15 miles an hour on the road.

Senior citizens or disabled people can drive mobility scooters up to 30 miles per hour on the road. These are similar to those battery-powered models (But seated units with shopping baskets are used) at grocery stores for the benefit of disabled people.

Are There Separate Laws for Driving a Moped in California?

Under California Law, a moped is a vehicle with two or three wheels, an automatic transmission accompanied by an electric motor, and a 30 miles an hour maximum speed.

The distinction between a moped and a motorized bicycle is the speed limit, as anything having speeds slower than 20 miles per hour is not a moped. Refer to the Department of Motor Vehicle if you’re unsure what law applies to your ride.

To legally drive moped, moped riders must acquire a motorcycle license (M1 or M2), their moped is registered with the DMV, and the relevant license plates. Upon registration, they will receive a moped ID card that they must always keep on them.

Electric Motor and Motorized Bicycle Laws in California

You may believe that motorized bicycles and mopeds are the same. However, these are treated differently under California law. An electric motor (fewer than 750 watts) and pedals are the main requirements to determine if a vehicle is a motorized bicycle in California.

The law breaks down electric bikes into three different categories, and these are as follows:

  1. Class 1: A motor on a bicycle that activates upon pedaling and deactivates once the ride reaches 20 miles an hour
  2. Class 2: A bike (electric) that does not require pedaling to propel the rider but does not go beyond 20 miles an hour
  3. Class 3: A bicycle equipped with a speedometer and a pedal-assisted electric motor touching speeds of no more than 28 miles an hour. To qualify for driving this motorized bicycle category, the rider must be over the age of 16.

Riders can only ride on a designated bicycle path or bike lane and can take advantage of the class II bicycle lane provided by the state.

A motorized bicycle rider must have a motorcycle license requiring the individual to pass the written and driving tests. There is no strict requirement on wearing a bicycle helmet if you’re above 16, unless you are riding on your learner’s permit.

Is There a Need for Insurance to Ride Motorized Bicycles?

Many wonder whether or not getting insurance to ride motorized bicycles is required.

Motorized scooters or bicycles do not require insurance, but if you’re riding a moped, you need to get insurance with at least minimum liability coverage of:

  • $15,000 – Bodily injury coverage for one individual
  • $30,000 – Total bodily injury coverage for the accident
  • $5,000 – Property damage coverage for the accident.


Watercraft refers to vehicles intended for travel on water. This category includes boats, ships, yachts, ferries, and other vessels used for transportation or recreational purposes.


Aircraft are vehicles designed to operate and travel through the air. This category includes airplanes, helicopters, gliders, drones, and other flying vehicles.

These three categories encompass the major types of vehicles, each with its specific characteristics and modes of operation.

What are the 4 basic divisions of a vehicle?

The four basic divisions or components of a vehicle are:

  1. Powertrain: The powertrain consists of the engine, transmission, and drivetrain components that generate and transfer power to propel the vehicle. The engine is responsible for generating power, the transmission manages gear ratios and transfers power to the drivetrain, and the drivetrain distributes power to the wheels.
  2. Chassis: The chassis is the framework of the vehicle that provides structural support and holds together the various components. It includes the frame, suspension, steering, and braking systems. The chassis ensures the stability, control, and maneuverability of the vehicle.
  3. Body: The body refers to the outer shell or structure of the vehicle. It provides passenger or cargo space, protection from the elements, and serves an aesthetic purpose. The body may be constructed from various materials such as steel, aluminum, or composites.
  4. Electrical and Electronic Systems: Modern vehicles are equipped with various electrical and electronic systems that perform functions such as lighting, climate control, entertainment, communication, and safety features. This division includes the wiring, sensors, control modules, and other electrical components that enable these systems to operate.

These four divisions encompass the major components and systems that make up a vehicle. Each division plays a crucial role in the vehicle’s operation, performance, and functionality.

Other Energy Sources

While traditional internal combustion engines predominantly rely on fossil fuels, several other energy sources and technologies have been explored and utilized in vehicles. Here are some examples:

Electric Vehicles (EVs)

Electric vehicles use electricity as their primary source of energy. They can be powered by rechargeable batteries, which store electricity for later use, or by fuel cells that convert hydrogen or other fuels into electricity. EVs are known for their low emissions and energy efficiency.

Hybrid Vehicles

Hybrid vehicles combine an internal combustion engine with an electric motor and battery. They can operate using either the combustion engine, electric power, or a combination of both. Hybrid technology helps improve fuel efficiency and reduce emissions.

Hydrogen Fuel Cell Vehicles

Hydrogen fuel cell vehicles use hydrogen as fuel to produce electricity through a chemical reaction with oxygen. This electricity powers the vehicle’s electric motor. These vehicles emit only water vapor, offering zero tailpipe emissions.

Renewable Fuels

Some vehicles can be powered by renewable fuels, such as biodiesel or ethanol we don’t always have to mine from the ground. These fuels are derived from renewable sources like plants, making them more environmentally friendly compared to conventional fossil fuels.

Human-Powered Vehicles

Human-powered vehicles, like bicycles or pedal-powered vehicles, rely on human energy to propel them. While limited in terms of speed and distance, human-powered vehicles are eco-friendly and serve as sustainable transportation options for short distances.

Other Alternative Fuels

Various alternative fuels have been explored, including natural gas (compressed natural gas or liquefied natural gas), propane, and biofuels derived from organic matter. It’s worth noting that the adoption and availability of these alternative energy sources and technologies vary by region and depend on factors such as infrastructure, regulations, and market demand.

Continued research and development are focused on expanding the range of energy sources and technologies to make transportation more sustainable and environmentally friendly. Tesla has built a number of sleek, crossover hybrid vehicles that have shown their usefulness as well. China controls much of the chips and other minerals needed for electric vehicles. So look to hydrogen fuel coming into its own as China quickly becomes more aggressive on the world stage.
