Epilepsy and driving is a personal and safety issue. A person with a seizure disorder that causes lapses in consciousness may be putting the public at risk from their operation of a motor vehicle. Not only can a seizure itself cause an accident, but anticonvulsants often have side effects that include drowsiness. People with epilepsy are more likely to be involved in a traffic accident than people who do not have the condition, although reports range from minimally more likely up to seven times more likely. It is for this reason that most people diagnosed with epilepsy are prohibited or restricted by their local laws from operating vehicles. However, most places have exceptions built into their laws for those who can prove that they have stabilized their condition. Individuals who may be exempt from such restrictions or may have fewer restrictions include those who had seizures as a result of a medical condition that has been cured, from a physician's experimental medication change that failed, as an isolated incident, whose seizures occur only while asleep, or who may be able to predict their seizures in order to ensure that they do not lose consciousness behind the wheel of a moving vehicle. After having one during the day they must wait 180 days to get their license back. The first seizure-related automobile crash occurred at the turn of the 19th century. Since then, laws have been enacted all over the world regarding driving for people with epilepsy. There is an ongoing debate in bioethics over who should bear the burden of ensuring that a person with epilepsy does not drive a car or fly an aircraft. Laws Some countries prohibit people who have ever had a seizure from driving. In these countries, it is common for people with epilepsy to hide their condition from authorities in order not to be denied a driver's license. Other places allow those who have had seizures to drive after a seizure-free period, which ranges from six months to a year. EU (European Union) harmonisation of periods of freedom from seizure means the periods shown below for EU states is wrong - now 6 months for an isolated seizure, 12 months for a second or more seizures within 5 years, whether or not antiepileptic drugs are taken. For drivers of heavy lorries and buses the seizure-free period is five years without drugs. Epilepsy driving laws by
