the limited-access highways within NYC, especially when NYPD Highway Patrol officers call for assistance or are unavailable due to limited manning and deployment elsewhere in NYC. Some highway patrol organizations, such as the Florida Highway Patrol and North Carolina State Highway Patrol, are specifically charged with the enforcement of traffic laws, and while able to enforce other laws, they are not an official "state police" agency, yet retain their statewide jurisdiction in the same vein as the California Highway Patrol or the New Jersey State Police. States like Texas have a bona fide and appropriately named state police department such as the Texas Department of Public Safety, of which only one arm is a highway patrol division. In addition, the police departments of Boston, New York City, Philadelphia, Nassau and Suffolk counties in New York have highway patrol bureaus. These units have special uniforms for their highway duty- service caps with the wire grommet removed, giving the classic "crusher" look, leather jackets, riding breeches, riding boots, Sam Browne-style belts and lanyards for their service pistols. A privately compiled list of Highway Patrol organizations and similar state police agencies is available on the web. The Iowa State Patrol maintains a list of phone numbers and cell phone dialing codes for non-emergency calls to the dispatchers of the Highway Patrol organizations in all 50 states. These numbers are useful for motorists who want to report aggressive driving, driving under the influence, or other dangerous but not life-threatening situations that do not require a 9-1-1 call. Highway patrol and state police officers are often referred to as a "state trooper". Historically, a troop was a small cavalry unit. Many state police forces originated as mounted paramilitary forces who were stationed in barracks like soldiers, hence the term "trooper." Some agencies, particularly on the East Coast, refer to their state police offices as "barracks", although troopers generally do not reside there. Other state police forces, particularly highway patrols as in California, have always modeled themselves after police officers who simply commute to work like ordinary civilians. Like police officers, they use the title "officer." Other states use the term "Patrolmen" in reference to members of the State Police or Highway Patrol. Many states and their Departments of Transportation have organized government-run freeway service patrols, Highway Assistance Patrols, or Highway Safety Patrols, to assist with highway emergencies as needed. While not law enforcement personnel, these
