Good Morning Britain viewers have blasted a guest who says smart motorways shouldn't be scrapped, despite admitting how they're "not ideal".

Peter Rodger, of the road safety charity I Am Road Smart, appeared on the show alongside Piers Morgan and Susanna Reid and said that the alternative to such motorways is "even worse".

Speaking to the duo, he said: "smart motorways are not ideal, but the alternative is even worse.

"If we don't have the road capacity on the motorway, what happens is the traffic goes off onto other roads."

Unsurprisingly, Piers Morgan had a lot to say on the matter and quickly interrupted to say: "The first priority of any road system should be safety.

"The number of near-misses on one section of the M25 has risen 20-fold since its hard shoulder was removed in April 2014.

"In the five years before, 72 recorded near-misses rose to 1,485 in the five years after."

Blasting Rodger's opinion, he then insisted: "That's not smart, that's stupid"

And it would seem Pier's is not alone, as lots of viewers tuning in from home took to Twitter to wade in on the debate, with many agreeing with the outspoken TV presenter.

One viewer said: "This guy has just said it’s better to have a car stop on a smart motorway, and risk getting killed is better than having cars seek alternative routes and congestion other roads #gmb no... life comes first surely #idiot#crazy#bonkers#frightening@piersmorgan@susannareid100"

Another added: "Been saying this for ages. No hard shoulder is bonkers!!! Nowhere to stop at all except in fast moving traffic. It’s terrifying. Been there done that. It’s terrifying #gmb@gmb#smartmotorway"

"Everytime I enter on to a Smart motorway, I say I prayer that I don’t break down. #smartmotorways#notsosmart#GMB." A third added.

Billions of pounds have been spent revolutionising UK roads to create smart motorways, where drivers use the hard shoulder as a live lane to reduce congestion.

They also use technology to limit speeds and close lanes.

However, in the last five years 38 people have died on these smart motorways

Currently, their roll-out has been put on hold amid safety fears.

It comes after one mum revealed her 'immeasurable grief' after her eight-year-old son was killed by a lorry collision on a smart motorway after visiting his critically ill brother.

The young boy, Dev, was killed instantly 45 seconds after his grandad's car stopped on the inside lane on May 31 2018.

Others also had their say on social media, with the majority of viewers calling for the motorways to be banned.

One commented: "Yes, smart motorways should be banned. A good number are not smart. The response time can be more than 30 minutes. Very dangerous to sit in the car of a live lane. More deaths have been caused by them."

A second said: "It should be called death trap motorway. Cant believe someone even thought of making it the way it is"

"Yes. Safety MUST be a priority at all times - stupid motorways compromise that. I would rather be delayed by a few minutes knowing I'm safe, rather than get home an hour early while putting my life at risk... #goodmorningbritain" A third agreed.

Another insisted: "And if theres an accident emergency ? What then ??? Stupid idea !!"

Someone else wrote: "Teach people how to drive motorways properly!! Ban middle lane drivers then they would be a lot safer!! They cause more accidents than anything...."
