Drink Driving and Drug Driving — Scotland's limit of 50mg of alcohol per 100ml of blood is the lowest in the United Kingdom, and it catches a great many drivers the morning after rather than the night before. We examine Intoximeter calibration and maintenance records, the procedure followed at the station, and whether the hip flask defence is open on the facts. Dangerous Driving — conviction brings disqualification for at least 12 months and a compulsory extended retest, so the line between dangerous and careless driving is usually where the case is won or lost. Careless Driving — a question of degree that is worth arguing properly. Speeding — Edinburgh's citywide 20mph limits generate a large volume of charges, and the A720 city bypass, the A1, the A90, the A70 and the A702 are all enforced; we check device type approval and calibration and whether a Notice of Intended Prosecution was served within 14 days. Totting Up and Exceptional Hardship — at 12 penalty points disqualification for at least 6 months is mandatory unless exceptional hardship is proved on evidence. Driving Without Insurance — 6 to 8 penalty points or discretionary disqualification. Mobile Phone Offences — 6 penalty points. Driving While Disqualified — a charge that carries a real risk of custody.
