Road traffic collision in the context of "Blunt trauma"

A firefighter (or fire fighter or fireman) is a first responder trained in public safety and emergency response such as firefighting, primarily to control and extinguish fires and respond to emergencies such as hazardous material incidents, medical emergencies, road traffic collisions and other emergencies that threaten life, property and the environment, as well as to rescue persons from confinement or dangerous situations and preserve evidence.

Firefighters may also provide ordinance regulations, safety requirements, and administrative public functions for the communities and areas they are subject to jurisdiction to. Male firefighters are sometimes referred to as firemen (and, less commonly, female firefighters as firewomen).

Road pricing are direct charges levied for the use of roads, including road tolls, distance or time-based fees, congestion charges and charges designed to discourage the use of certain classes of vehicle, fuel sources or more polluting vehicles. These charges may be used primarily for revenue generation, usually for road infrastructure financing, or as a transportation demand management tool to reduce peak hour private vehicle travel and the associated traffic congestion or other social and environmental negative externalities associated with road travel such as air pollution, greenhouse gas emissions, visual intrusion, noise pollution and road traffic collisions.

In most countries toll roads, toll bridges and toll tunnels are often used primarily for revenue generation to repay long-term debt issued to finance the toll facility, or to finance capacity expansion, operations, and maintenance of the facility itself, or simply as general tax funds. Road congestion pricing for entering an urban area, or pollution charges levied on vehicles with higher tailpipe emissions are typical schemes implemented to price externalities. The application of congestion charges is currently limited to a small number of cities and urban roads, and the notable schemes include the Electronic Road Pricing in Singapore, the London congestion charge, the Stockholm congestion tax, the Milan Area C, and high-occupancy toll lanes in the United States. Examples of pollution pricing schemes include the London low emission zone and the discontinued Ecopass in Milan. In some European countries there is a period-based charge for the use of motorways and expressways, based on a vignette or sticker attached to a vehicle, and in a few countries vignettes are required for the use of any road. Mileage-based usage fees (MBUF) or distance-based charging has been implemented for heavy vehicles based on truck weight and distance traveled in New Zealand (called RUC), Switzerland (LSVA), Germany (LKW-Maut), Austria (Go-Maut), Czech Republic, Slovakia, Poland, and in four U.S. states: Oregon, New York, Kentucky, and New Mexico.
