The idea is being floated by the current Road Safety Minister Mike Penning, but is likely to face stiff opposition from many safety organisations and the green lobby and well as within Parliament on the grounds of the cost to implement.

But, says Graham Hurdle, MD of E-Training World, the high speed limit could have benefits to business in speeding up traffic flows on Britain’s busiest road systems.

He commented: 'The 70mph limit was imposed a long time ago and there is no doubt that car performance, tyres, brakes etc have improved to an incredible extent.

'A large proportion of drivers are already travelling at 80mph plus so raising the limit to 80 would simply be legalising what is already happening. It is an anomaly that motorways are generally the safest roads, yet the speed limit is constrained to that of a dual carriageway and it would be a popular move and would reduce journey times on some routes,' he added.

He also points out that the UK speed limit is current one of the lowest in Europe.

'Parts of the German autobahn network are still unlimited and in quite a few countries including France it is 130kph (about 83mph) in the dry and 110kph (68mph) in the wet in France. Other countries have a 120kph (76mph) limit, so the UK limit is out of kilter with the approach taken across many other European countries.'

Mr Hurdle believes that the safest way to implement any increase in the maximum limit would be to restrict it to the lengths of controlled motorway, where variable speed limits can be posted. In this way the limit could be adjusted to suit the prevailing conditions (night time, good weather, light traffic) whether this is to reduce them or increase them up to 80mph.

'By using these areas as a test bed would be the most logical way forward,' he concluded Graham, 'because the higher limit could only be allowed when safe to do so, with the flexibility to reduce it back down when speeds need bringing under control.'
