INTRODUCTION
In today’s fast world the people are getting faster and they did not have to stop. Population is also increasing by with no. of vehicles are increasing day-by-day. Due to increase in no. of vehicles road accidents are also increasing and to avoid this we should use road safety.
ROAD SAFETY
The term road traffic safety is an indication of how safe individual users are on some particular road, or on the roads belonging to some region. The main danger to road users is the likelihood of a traffic collision. Such dangers can be reduced by individual road users operating cautiously and defensively, by building roads in alignment with competent traffic engineering practices, by the application of rational traffic control methods, and by designing road vehicles so they are more able to avoid and survive collisions.
BACKGROUND
Road traffic crashes are one of the world’s largest public health and injury prevention problems. The problem is all the more acute because the victims are overwhelmingly healthy prior to their crashes. According to the World Health Organization (WHO), more than a million people are killed on the world’s roads each year A report published by the WHO in 2004 estimated that some 1.2m people were killed and 50m injured in traffic collisions on the roads around the world each year and was the leading cause of death among children 10 – 19 years of age. The report also noted that the problem was most severe in developing countries and that simple prevention measures could halve the number of deaths.
TRAFFIC SIGNS

TRAFFIC COLLISION
A traffic collision, also known as a traffic accident, motor vehicle collision, motor vehicle accident, car accident, automobile accident, Road Traffic Collision (RTC) or car crash, occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other stationary obstruction, such as a tree or utility pole. Traffic collisions may result in injury, death and property damage.
A number of factors contribute to the risk of collision including; vehicle design, speed of operation, road design, road environment, driver skill and/or impairment and driver behavior. Worldwide motor vehicle collisions lead to death and disability as well as financial costs to both society and the individuals involved. Traffic collision occurs by the mistake of the driver.
SAFETY MEASURES
CAR
A car accident is one of the most dangerous things the average person will come in contact with during her life. This guide is posted in the hope that it will help its readers avoid injury or death. It should be noted that every vehicle is different, and much of the information here (such as airbags) will not apply to those who drive vehicles from 1990 or earlier. The methods of avoiding an accident, and the position one should be in during a crash, however, are effectively universal.
STEPS:
Drive a safe car which is fitted with seat belts and other safety features. Do not sit in a seat which has no head support. Older cars, which may just have lap belts and almost never have any additional safety features, are generally less safe than large vehicles. SUVs tend to be more prone to rollover accidents than cars. Try to drive the safest car that suits your needs and budget. The Insurance Institute for highway safety maintains extensive crash test ratings and lists of safe vehicles of different sizes and styles.
Store objects such that they will not hit you if the car gets hit. If an object could become a projectile during a crash, either remove it from the car, or stow it in the trunk, or, in the case of a minivan, in the well behind the seat.
Make sure the safety systems on your car are serviced regularly. Airbags and seat-belts significantly reduce injury and death in automobile accidents.
Make sure your car's engine, brakes, transmissions, suspension and tires are in good condition. The safest accident is the one you don't get in; having your car in top running condition can help you avoid an accident or minimize harm in case you get in an accident.
Accelerate if needed. Although it seems counter-intuitive, sometimes the best way to avoid an accident is to speed up and get out of the way.
Functions of PPE

Abrasion Resistance — Thick, tough leather provides the most abrasion resistance in a crash, but fabrics such as Cordura, Kevlar and ballistic nylonprovide significant protection too. In addition, fabrics are generally cheaper, easier to maintain, waterproof, and more comfortable in hot weather. Thick leather, which affords the most abrasion resistance, can be uncomfortable in temperatures exceeding 85 °F (29 °C) and above 100 °F (38 °C) may cause heat stress & loss of control with insufficient fluid replacement. Some PPE may be constructed of fabrics made into a 'mesh' that provides cooling and a stable surface for the attachment of padding (see below).
Impact protection — Quality jackets and pants provide significant extra padding in the vulnerable joint regions described above. This can take the form of simple foam padding, or dual-density foam that stiffens when compressed, sometimes with plastic or carbon fiber outer-shells that distribute the impact across the pad. Integrated pieces can be found in some jackets.
Weather Protection — One important aspect of PPE not mentioned above is protection from the elements. Extreme weather can make a long ride unbearable or dangerous. PPE provides protection from wind, rain and cold.
Items of PPE
Gloves — Commonly made of leather, cordura, or Kevlar, or some combination. Some include carbon fiber knuckle protection or other forms of rigid padding. Gloves designed specifically for motorcycle use have slightly curved fingers and the seams are on the outer surfaces to allow the motorcyclist to maintain his grip and control on the handlebars and clutch/brake levers. Some gloves also provide protection to the wrist.

Pants — Made of the same material as jackets, usually including special protection for the knees and hips.

Goggles or Helmet Visor — Eye protection is of utmost importance - an insect or a kicked-up pebble in the eye at speed has enough momentum to cause significant damage. Such an event could easily cause the rider to lose control and crash. Besides this danger, squinting into the wind is unpleasant at best and watering eyes are quite distracting.
Ear plugs — Most riders experience substantial wind noise at speeds above 40 to 50 mph (64 to 80 km/h). Ear plugs help protect against hearing damage, and reduce fatigue during long rides.
Vests — Made with high-visibility colors and retroreflective materials, vests can be worn over jackets to increase the chance of being seen and allow drivers to better judge the speed and position of riders, especially in adverse conditions of dark and wet.
Other PPE — Dirt bike riders wear a range of plastic armor to protect against injury from falling and hitting other riders and bikes, running into track barriers, and being hit by flying debris kicked up by the tires of other riders' bikes. This type of armor typically covers the back, chest, and sometimes the extremities.
It is increasingly common for gloves, jackets, pants, and boots to be outfitted with hard plastics on probable contact areas in an effort to ensure that when a motorcyclist contacts the ground, his clothing will permit him to slide relatively easily as opposed to "crumpling", risking injury to body parts being stressed in abnormal directions.

From above written material you all know that safety worth. Safety matters.Some safety quotes:
"Out of this nettle, danger, we pluck this flower, safety."
