Crash barriers keep the vehicles from going off the road and steer them safely back on to the road. It wouldn’t be an exaggeration to say that their very presence can boost the confidence of a jittery driver on a mountain road.
Crash barriers can be classified on the basis of their design and implementation. Guardrail, wire rope safety barrier, crash cushions and high containment barrier are a few that can be seen on roadways. All the
crash barriers work on a similar principle, they are designed to absorb the impact of the vehicle going off track and hence help it get on to the road again without letting it lose its balance.
At times, the crash barrier to be used on a roadway is determined by the kind of vehicle traffic the roadway gets. For example high containment barriers are put up on the roadways with a large traffic volume of heavy vehicles. Then, crash cushion is specifically designed to protect motorists from impacting the end of concrete barriers and toll plazas. Guardrail is the most commonly seen crash barrier but has a history of highest injury and fatality in a fixed object crash. This is where wire rope safety barrier scores over guard rail as it consists of wire ropes and is flexible.
Though the crash barriers prevent several accidents everyday, they sure don’t prevent all of them. There have been incidences of fatalities, which were mainly attributed to the design and material of the crash barriers. Most of the roadways get all types of automobiles and therefore it becomes difficult to decide on the height and strength of the crash barrier. For, a motorbike can slip under the barrier that’s meant to keep a car from going off track, while a big truck may trip well over the same barrier.
As a step towards ensuring safe road travel, road safety products are first tested and then put up on roadways. The crash barriers are tested in accordance with the guidelines mentioned in National Cooperative Highway Research Program (NCHRP) Report 350, “Recommended Procedures for the Safety Performance Evaluation of Highway Features”.
These guidelines are based on the findings of continuous road safety researches and are subject to revision.

The Insurance Institute for Highway Safety (IIHS) released its most recent crash-test ratings but did not endorse any models evaluated. Instead, said institute urged auto consumers to stick with bigger, heavier vehicles because they typically are safer for motorists. IIHS real-life crash results also revealed that subcompacts are not the best safety choice. This information was divulged by Adrian Lund, president of IIHS
Subcompacts are the smallest vehicles on the road these days. The recorded crash rates involving subcompacts are higher than in other auto category. As a fact, the rates are more than twice the death rates for midsize and large vehicles.
IIHS evaluated a total of 9 cars weighing 2,500 pounds or less. Said cars are smaller than Honda Civic compact. This is because body parts for Honda Civic are made heavier and tougher. Crash ratings of the cars ranges from good, followed by acceptable, marginal and poor.
Among the nine subcompacts Nissan Versa rates the highest in 3 crash-test categories named front, side and rear. Nissan OEM body parts are engineered to stand the complexities of driving. Next to Versa is Toyota Yaris. The latter gets good in both front and side crash tests and marginal in the rear crash test. Toyota auto body parts are also meticulously assembled to ensure safety of the car occupants.
The worst performers in the IIHS crash-tests are Hyundai Accent and Kia Rio. Said cars earned acceptable rating in the front crash test but poor in the side and rear tests. "Hyundai is targeting July production to add the Accent to its list of vehicles equipped with active head restraints," said Miles Johnson Hyundai spokesman. The rear crash-test rating is based on headrest criteria.
It was found out that the vehicles that were given high ratings were equipped with side air bags and head-protection systems. "Larger cars provide more protection, even slightly larger, and they get almost as good gas mileage," Lund noted. "Some of the midsize cars like the Accord and the Camry, if you get them in the four-cylinder versions, have as good a gas mileage as the mini cars. If you really want to save fuel, buy a larger car that's less powerful than a smaller lightweight vehicle that also sacrifices your safety."
