I. Human Factor
This constitutes about 90% of road traffic crashes. Out of this percentage, drivers' action or reaction makes up 80%.
Human factor can further be classified under the following:
Human factor can further be classified under the following:
Drivers:
- Overconfidence: Drivers often feel that they are masters of the vehicle and road.
Failure to ensure good working condition, as well as observing safe driving measures while on the road will result in road traffic crashes.
- Speeding: Drivers believe that the faster they drive, the more they impress themselves and others.
More disasters and casualties are recorded when vehicles travel at higher speed than what obtains at low speed.
At 100 Km/hr, a vehicle moves at 28 meters per second. Imagine where driver would be if this vehicle veers off the road for 1 second, bearing in mind that the road is usually 12 meters wide.
Drivers forget that they cannot control the road, weather conditions and the environment.
0n-coming vehicles or vehicles being overtaken may do the unexpected, like swerving, stopping or trying to avoid pot holes. Furthermore, some of the roads have narrow bridges hidden around the corner.
- Lack of Concentration: Drivers often engage in things that distract their attention while driving.
Lack of concentration is very dangerous as it takes only a moment for crashes to occur. The vehicle in front may stop abruptly or a child may run into the road suddenly; hence anything can happen.
Be alert, always anticipate danger.
- Tiredness: Some drivers drive long distances without even stretching their legs and improving their blood circulation to the brain. This makes the drivers feel tired and sleepy.
Again driving after a heavy meal can also be hazardous as the blood concentrates in the stomach to absorb the food, thus depriving the brain of oxygen which can cause the driver to fall asleep.
Over working also causes fatigue. Some articulated vehicle drivers work an average of 9 to 12 hours per day which is dangerous.
- Driving under the influence of alcohol: Alcohol can cause over confidence, poorjudgement, lack of coordination and recklessness.
Numbers of Bottles | Percentage Concentration of Blood | Behavior |
1 | 0,01-0,02 | Slight behavior |
2 | 0,03-0,06 | Feeling of wanmh and mental ralaxation |
3 | 0,07-0,09 | Exaggerated emotion and behavior or noisy or gloomy |
4 | 0,10-0,12 | Clumsiness, unsteadiness in standing or working in uncoordinated movement |
5 | 0,12-0,60 | Gross intoxication |
- Driving under the influence of drugs: Drugs can interfere with the ability to drive, Sometimes drugs that are prescribed by doctors have sedative (i.e, sleep inducing) effect on the driver.Coffee and kolanut are stimulants that tend to increase the alertness of drivers. Another stimulant popularly taken by these drivers is Indian hemp which is a street drug, and sometimes cocaine.
Some drivers have been known to use chewing sticks to keep their mouths active, with the aim of staying awake. Remember, these drugs are no substitute for rest.
- Poor vehicle care: Drivers often do not check their vehicles to ensure that they are in good condition for the road before setting out on a journey.
- lndiscriminate Parking: Parking a vehicle in the middle of the road just to change a tyre or because of engine trouble is among the causes of road traffic crashes especially at night or around a sharp bend or close to the crest of a hill where the vehicle cannot be seen far off by other road users.
In some cases hazardous obstacles placed on the road to warn or divert traffic, are left behind when the vehicles move on after repairs. This endangers other road users and may result in crashes.
S.10(3)(i) FRSC Act 2007
- Dangerous overtaking: This is responsible for about 45% of all crashes. Careless overtaking and poorjudgement combine to cause road traffic crashes.
S.10(4)(j) FRSC Act 2007
Passengers:
- Distraction: Passengers contribute to road traffic crashes by engaging the driver in discussions and arguments.
8.50 National Road Traffic Regulations. 2004
- Nonohalant Attitude: Passengers board buses, taxis and private vehicles without even taking a look at the tyres to see if they are worn out.
You can report this to the driver's employer or to the first traffic authorities you encounter on the road, or demand to be set down at the next convenient spot if the driver persists on driving recklessly, before he drives you to death.
Remember, crashes claim the lives of more passengers than drivers. 0n the average, eight passengers are killed along with only one driver.
S.10(3)(i) FRSC Act 2007
- Pedestrians: Pedestrians contribute to road traffic crashes by not observing road traffic rules and regulations.
These behaviours contribute to road traffic crashes.
