Talking Point: Should UK speed limit be changed from 70mph to 80mph?

With speeding fines set to increase to up to £2,500, breaking the speed limit is no trifling matter. But are the limits at the right level in the first place?

The 70mph motorway speed limit was first introduced for a trial period in 1965 in a bid to cut accidents, then made permanent in 1967.

But 50 years on, is 70mph still the right speed for motorways? As some parties argue that safety features and modern technology has made driving safer, is it the right time to raise the limit? Equally, there is talk of reducing speed limits in certain sections to deal with air pollution.

Edmund King said: ‘Our view is that 80mph in a modern car, in good weather, driven at a safe distance from the car in front is a safe speed. Whereas 50mph in bad weather, tailgating the car in front is a very dangerous speed.

‘Given the progress that has been made in vehicle capability and safety in the 50 years since the 70mph speed limit was introduced, it would be reasonable to reassess the speed limits in areas where the highways are suitable; such as long, wide, straight stretches of motorway with a permanent hard shoulder.

‘Through less suitable stretches, it would be sensible to adopt a similar approach to that taken on many European roads, where the speed limits vary depending on hazards (such as entry slip roads or sharp bends).

‘In poor weather such as ice and heavy rain, variable speed limits managed via overhead gantries could be used to effectively slow traffic, reducing the limit to one more appropriate for the driving conditions.’

An AA-Populus driver poll showed that the majority (61%) feel motorway speed limits should be increased to 80mph. However, a quarter of respondents felt that if the speed limit were to be raised it should be strictly enforced, while just over a third (36%) said it should be enforced according to current ACPO guidelines (with a discrepancy of 10% +2mph).

Lucy Amos said: ‘Cars on British motorways currently have a speed limit of 70mph, while some larger vehicles, including articulated trucks and vehicles towing caravans, have a speed limit of 60mph.

‘While vehicles vary in their braking ability, a car travelling at 70mph has a total stopping distance, in dry conditions, of about 96m, or 24 car lengths. This is greater in wet and icy conditions. If braking is carried out by the driver (rather than an automated emergency braking system) the car will travel about 21 metres in less than a second before the driver can even hit the brakes.

‘There have been previous occasions where the government has proposed raising the UK motorway speed limit to 80mph, but evidence has shown repeatedly that any increase in speed increases both stopping distances and crash likelihood.


‘At 80mph stopping distances are 27% greater than at 70mph (about 122 metres compared to 96 metres), a distance that would significantly lessen the reaction time available to the driver when faced with a dangerous situation.

‘It is unlikely that raising the motorway speed limits will improve journey times, especially on a congested network. Instead, research has predicted that raising the speed limit would result in 25 more deaths and 100 more serious injuries annually on our motorways.

‘Parliament’s Transport Select Committee estimated it would result in a 10% rise in casualties on motorways, meaning that to do so would not only be irresponsible but also endanger the lives of countless road users on the strategic highway network.’
