Over speeding on roads
In road traffic, the term speeding refers to the state of a motorist driving at a rate exceeding the legal speed limit. For example, a driver traveling at 60 kilometers per hour along with a speed limit of 50, is considered to be speeding. Speeding has been a major contributory factor in crashes that occur on roads in Accra and the country at large.
The physics of a crash
In a crash, it is the amount of kinetic energy that is imparted which causes injuries or death. This kinetic energy increases exponentially with speed. A doubling of speed is not equal to twice as much kinetic energy, but rather a substantial increase of much more than it is much more lethal. At 20% increase in speed is approximately 45% increase in kinetic energy.
In a high-speed crash, a vehicle handles the force of the crash. As crash speeds get very high, airbag and seat belts do not work to keep pbadengers safe.
Speed influences the risk of crashes and crashes
By the time the driver realizes the need to react, they would have traveled closer to the danger.
This causes a majority of drivers who find themselves in this situation to try stepping hard on the brakes.
This increases the general impact of the crash.
If a driver doubles their speed – for instance from 30mph to 60mph – the braking distance does not get twice as far. It becomes four times as far. Traveling at 55 mph, it will take about 6 seconds to stop the vehicle. The vehicle will travel 302 feet before coming to a stop. That is longer than the length of a football field.
When a driver is speeding, other drivers have a hard time telling how fast they are going.
A driver should consider road conditions, weather and road design and slow down when those change. For instance, it is easier to lose traction when speeding around a curve and the center of gravity makes it easier to roll over. A driver should slow down before curves.
