Local laws against driving while intoxicated are growing stricter. Many bars now serve non-alcoholic drinks for those nominated to do the driving. For non-emergency assistance when traveling, call Travelers' Aid, an organization that specializes in helping distressed travelers, whether American or visitors from abroad. Alternatively, dial 0 and ask the operator. If you are required to stop by a police officer, remain seated in your car, switch off the engine and await instructions from the approaching officer.
Most officers are firm, but courteous.
They are more likely to let you off with a verbal reprimand if you are civil and prepared to understand the reason why they've stopped you. The majority of vehicle stop-checks are now recorded on video camera, with police officers wired for sound, so anything you say or do will be recorded. Always carry your license and vehicle documentation. Pay fines by mail, or directly to the clerk of the court. In the event of a minor collision, the advice is to stay in your car with the doors locked.
