In 2016 a very young driver, Miss W, had a road accident whilst driving and was taken to hospital. On arrival, she asked paramedics for permission to go to the toilet. They checked with police and permission was given. She was then placed under the care of a doctor. Her mother arrived quickly as police had called her. She could not provide breath because samples can only be taken into the police station and so police required her to provide urine. She was dehydrated prior to going to the toilet, and despite her best efforts over the following hour by drinking plenty of water, she couldn’t go again. The police charged her with failing to provide urine. Her defence was that she had been too dehydrated and police had given her permission to go to the toilet. She was found not guilty with the court accepting evidence from her and her mother that she had done her best.
