On 1 March 2011, the European Court of Justice decided insurance companies who used gender as a risk factor when calculating insurance premiums were breaching EU equality laws. The Court ruled that car-insurance companies were discriminating against men. However, in some places, such as the UK, companies have used the standard practice of discrimination based on profession to still use gender as a factor, albeit indirectly. Professions which are more typically practised by men are deemed as being more risky even if they had not been prior to the Court's ruling while the converse is applied to professions predominant among women. Another effect of the ruling has been that, while the premiums for men have been lowered, they have been raised for women. This equalisation effect has also been seen in other types of insurance for individuals, such as life insurance.
A compulsory car insurance scheme was first introduced in the United Kingdom with the Road Traffic Act 1930. This ensured that all vehicle owners and drivers had to be insured for their liability for injury or death to third parties whilst their vehicle was being used on a public road. Germany enacted similar legislation in 1939 called the "Act on the Implementation of Compulsory Insurance for Motor Vehicle Owners."
