The only safe option is not to drink alcohol if you plan to drive, and NEVER offer an alcoholic drink to someone else who is intending to drive.
Remember also that you could still be over the limit if driving the morning after!!
Driving under the influence of drugs, whether prescribed medication or illegal substances, is just as dangerous as driving under the influence of alcohol and is also against the law. But are you aware that some prescribed drugs, and those you can buy over the counter such as cold and flu medicine, can also have an affect on people’s ability to drive.
