What does the California Vehicle Code regulate? Quick Answer

The California Vehicle Code regulates all aspects of motor vehicle use, including licensing, registration, insurance, traffic laws, DUI offenses, autonomous vehicles, and commercial trucking. It applies to both drivers and vehicle-related businesses, while excluding rail, sea, and air transport.

Summary

  • The California Vehicle Code has over 30 chapters and hundreds of laws
  • The code regulates all aspects of motor vehicle transportation
  • The state government imposes penalties for code violations

The California Vehicle Code is a sprawling set of laws that covers motor vehicle issues that range from obtaining a driver’s license to transporting explosives. The code includes hundreds of laws governing trucking companies, automobile dealers and drivers.

What the California Vehicle Code Covers

The California Vehicle Code focuses on road transportation, including the following matters:

  • Mandatory auto insurance requirements
  • Traffic laws
  • Vehicle registration and driver licensing regulations
  • Equipment requirements
  • Autonomous vehicle operation restrictions
  • Trucking regulations
  • Vehicle dealer rules

It also covers off-road vehicles and how operators may use them in California. However, the code does not regulate rail, sea and air transportation.

How the California Vehicle Code Is Used

The California Vehicle Code serves two purposes. First, the state uses it to regulate the businesses involved in vehicle sales, modification and operation. Second, the code sets out the rules of the road for drivers, bicyclists and pedestrians.

California Vehicle Code and DUI Cases

The code includes the state’s DUI statute. It describes the following actions as unlawful:

  • Driving while impaired by drugs or alcohol
  • Driving with a blood alcohol content over the legal alcohol limit

A DUI is a criminal offense punished by a fine and possible jail time.

Penalties for Violating the California Vehicle Code

Unlike DUIs, most violations of the state’s rules of the road are infractions. These violations are punished with fines. If you fail to pay the fine or contest the citation, you can face additional penalties.

How to Request a DMV Hearing

The code gives the California DMV the authority to suspend your driver’s license in the following situations:

  • Failure to report an accident
  • Involvement in an accident while uninsured
  • DUI conviction
  • Too many points on your driving record
  • Underage drinking
  • Violating the state’s implied consent laws by refusing a drug or alcohol test

You can challenge the suspension by requesting a hearing by calling a DMV office within 10 days after receiving the notice of suspension.

Understanding Key Sections of the California Vehicle Code

The California Vehicle Code is organized into over 30 divisions, including the following key sections:

  • § 14601.2: Driving with a Suspended License Due to DUI | California Vehicle Code

  • § 23152: DUI Laws and Penalties | California Vehicle Code

  • § 22651: When Your Vehicle Can Be Towed | California Vehicle Code

    • Frequently Asked Questions

    • The code does not determine who is liable for a car accident. However, it sets out the rules for a judge or jury to determine liability. Specifically, the code states that drivers and owners are liable for auto accidents caused by their negligent or wrongful acts.

    • The government enforces the code by investigating violations and issuing fines. Private individuals cannot sue for a violation unless it harms them in some way. For example, a victim can use a trucking company’s violation of hazardous materials laws to prove liability after a truck spills toxins, causing a chemical exposure injury.
