Drivers support wider use of average speed cameras on motorways - despite more than half admitting to breaking the 70mph-limit

More than half of drivers (56%) admit to breaking the speed limit on motorways with a third (34%) of those confessing to having travelled at speeds in excess of 80mph, research from the RAC reveals.

Three per cent say their fastest speed on a motorway was over 100mph while 4% believe their top speed was 91-100mph. While the vast majority – two-thirds (66%) – state their highest speed on a motorway was 71-80mph, a quarter (27%) claim to have driven at 81-90mph.

When asked why they broke the speed limit on a motorway, most drivers (39%) said they were simply following the example set by other motorists, although three-in-10 (31%) say it was because they thought it was safe to travel faster than 70mph. Other common reasons for speeding on a motorway were: nothing else being on the road (28%); the speed limit being inappropriate (27%) and feeling pressure from other drivers behind (26%).

In terms of what form of speed enforcement drivers think is best for ensuring speed limit compliance on high speed roads where the speed limit is 60mph and 70mph, 58% of the 3,000-plus motorists surveyed for the RAC Report on Motoring said they favoured ‘average speed cameras’ which measure speeds between cameras rather than at a single, fixed location like traditional speed cameras. Nearly a fifth (18%) felt fixed position cameras are most effective while 12% said it was mobile speed traps, with a similar proportion not offering an opinion.

While average speed cameras are used on a number of A-roads, on motorways they are currently only used in sections of roadworks. More than half of drivers (54%), however, said they would like to see them used in general motorway conditions enforcing the 70mph-limit. Only a quarter (26%) disagreed with this idea, with 18% unsure.

Average speed cameras were also preferred by the majority of drivers for use on 40-50mph limit roads with 46% saying this, compared to 29% for fixed position cameras. On 20-30mph limit roads however, fixed position cameras came out top with 43% of drivers saying they were best and a quarter (25%) opting for average speed cameras, only just ahead of police officers operating mobile speed traps (21%).

While compliance on roads with lower speed limits is far better than the 54% who admit to exceeding the 70mph-limit, an alarming four-in-10 (39%) still admit to frequently disobeying 20mph limits. This rises to a third (33%) on 60mph country roads – statistically some of our least safe roads – and to 36% on 30mph urban roads.

Very worryingly, 11% of limit-breakers claim to have driven above 40mph in a 30mph zone while 10% have exceeded 30mph in a 20mph zone. In the case of the latter, 45% of those who speed at least occasionally say this is because they believe the limit is ‘inappropriate’ for the area or stretch of road in question.

RAC road safety spokesman Simon Williams said:

“Despite more than half of drivers admitting to regularly exceeding the 70-mph speed limit, road safety statistics clearly show that motorways are our safest roads.

“With so many motorists admitting to driving much faster than they should on the motorway, it was interesting to see such strong support for average speed cameras to be used more widely to enforce the 70-mph limit as opposed to just in roadworks, as is currently the case. We believe drivers see these cameras as being very effective at reducing speeds over longer distances and controlling traffic flow as well as being fairer than fixed position ones as they aren’t instantly punished for a momentary transgression.

“Our research shows speed limit compliance on all types of road has improved on previous years, but as our study was carried out during the pandemic we suspect this has partly been brought about by the reduction in the number of journeys carried out for the purposes of commuting – or for other business purposes – where drivers feel greater time pressure and may be more tempted to break the law by speeding.”
