There are strict penalties for those failing an alcohol test.
The legal blood alcohol concentration (BAC) limit in Italy is: less than .05%, also defined as 0.5 grams per litre of blood (50 mg/100 ml of blood).
Italian police may carry out random alcohol tests on drivers at anytime. Testing is more common around Christmas, New Year and in the main holiday period of July and August.
Drivers involved in accidents or who are driving erratically are subject to automatic testing.
The police may confiscate the driving license of a person driving while intoxicated. Failure of a blood-alcohol test has serious implications:
* the vehicle will be impounded
* the driver will be fined
* the driving license will be confiscated
* the driver may be imprisoned
Vehicle insurance is voided if an accident is caused while the driver is under the influence of drugs or alcohol; the insurance company has no obligation to pay for medical expenses or those injured.
If a driver is found to have traces of marijuana, hashish, cocaine or other banned substance in their system they face a driving ban of up to 12 months.
