If your doctor has put you on medication, ask if it’s okay to drive.
Drugs like sleeping tablets and pain killers - even cold and flu tablets - can sometimes make it hard to concentrate when you’re driving.
Different people can be affected differently by the same drugs. Read the labels on the packet. If you think your drugs could affect your driving, check with your doctor or chemist.
If you have any concerns, it's best not to drive until you're sure you're able to drive safely.
