A bribe is something of value offered, given or solicited to influence a person in a position of responsibility to act contrary to his or her duty. The giving or receiving of bribes often means breaking the second and the fourth Precepts and always involves cheating, greed, injustice and law-breaking.
When you beat the traffic law, you are supposed to pay for the fine, because that’s what the law is for. So when we try to get the easy out by bribing the police officers, then we are no different than cheating, we are cheating the law of traffic. By doing this, you are actually creating the cause for you to do the second time, the third time and so on.
In fact, if the police officers are asking money from you, or giving you hint for bribing, that’s enough for you to launch the report towards the police officers. By paying him money, it actually encourages him to do it to other people in the future and such action will create a continuous act of bribery.
