Briefly explain five contributory factors to most accindents in the world

Some of the factors contributing to most accidents in the world are as follows:
1- Drugs
2- Alcohols
When the driver is under the effect of either one of them, he/she cannot control the vehicle or drive it in a straight line. 
3- Anger
4- Stress
When the driver is angry or stressed, he/she might shake and cannot control his/her nerves and might lose control over the vehicle. Also their mind might not be thinking clearly to make proper decisions while driving (they can forget to signal before turning and so on).
5- Seeking attention.
Some driver , especially teenagers, are sometimes just looking for attention through reckless driving. The driver might lose control over the vehicle as a result of this reckless driving and this might lead to accidents.
