*Determining Whether a Driver is Inebriated
In the UK, laws set out express measurements for judging whether a driver is intoxicated. A driver who surpasses any of these boundaries is believed to be drunk driving and is subject to serious penalties.

1)the blood alcohol limit is eighty mg of alcohol per one hundred milliliters of blood
2)For piss tests, the limit is 107 mg of alcohol per one hundred milliliters of piss
3)For breathalyzer tests, legal limit is 35 micrograms of alcohol per one hundred milliliters of breath

*Requirements for Administering a Breathalyzer Test
One way for a policeman to establish whether a driver is drunk is to need the driver to take a breathalyzer test. Any individual who is driving, trying to drive or who is in charge of an automobile on a road, road or any public place is subject to being stopped and tested. However, there are explicit needs that really must be met for a law officer to make a suspected drunk driver take the test. First, the office must be on duty and wearing a uniform. Then one of the following 3 circumstances must be present:-

1)The police officer has reasonable cause to accept that either a moving traffic offence has been committed or a moving traffic offence is getting ready to be committed.
2)The police officer has reasonable cause to think the individual operating the car has been using alcohol.
3)The lawman has reasonable cause to accept that the individual operating the automobile has been bound up in an accident.

*Dangers of Drinking and Driving
Driving while under influence of alcohol or drugs is perilous for a considerable number of reasons. Driving talents are seriously reduced as the alcohol damages vision, slows reaction time and lessens a person's capability to make sound judgments. Also, the driver's eyes will be less responsive to red lights, eg traffic signals and brake lights. Drunk drivers are less targeted on the road and less ready to recognize potential hazards. All these factors mix to make a drunk driver rather more likely to be bound up in an accident and hurt themselves or somebody else.

*Penalties for Drinking and Driving
Those that drink and drive are liable to both civil and criminal penalties. If a drunk driver harms someone else, they can be held liable with an individual injury compensation claim. Criminal sanctions for drunk driving are serious too. First-time offenders can have their license revoked, be dispatched to jail and / or fined an amount up to £5,000. A drunk driver who has committed their second offence inside a period of 10 years faces a three-year revocation of their license; the same penalty is applicable to offenders with a blood alcohol level surpassing two hundred mg.
