Around 250,000 drivers don't know the motorway speed limit - according to the AA. Research from the Basingstoke-based company shows that younger drivers are more aware of speed limits than older drivers - one in ten of whom think the limit for cars on the motorway is 80mph.

Some confusion about the motorway speed limit for cars could well be down to the previous Transport Secretary floating the idea of raising the limit to 80mph. There is no reason why drivers shouldn't be able to correctly identify the speed limit of dual carriageways and single carriageways. The lack of knowledge around limits just highlights the importance of keeping your driving skills up to date. This follows a previous AA study that showed that some 17 million drivers would struggle retaking their driving test.
