How is the highway transportation system primarily managed?

The highway transportation system is primarily managed by the DMV, law enforcement, and traffic courts due to their respective roles in ensuring safe and efficient travel on roadways. The Department of Motor Vehicles (DMV) oversees the registration of vehicles and issuance of driver's licenses, which are crucial for regulating who has the authority to drive. Law enforcement agencies are responsible for enforcing traffic laws, investigating accidents, and maintaining order on the roads. Traffic courts adjudicate violations of traffic laws, dealing with offenses such as speeding, driving under the influence, and other infractions that affect road safety. Together, these entities create a framework that upholds the rules and regulations necessary for a safe highway transportation system.
