Motorists faced lengthy delays after a cyclist strayed onto the M25 during rush hour.
The rider caused chaos for morning commuters after a satnav app on his phone directed him to the southern section of the motorway in Surrey.
He ended up pedalling for several miles along the hard shoulder before he was eventually removed by police.
One officer tweeted that the cyclist had been seen between junctions 12 and 13 of the motorway.
The man was given a £50 fine, police said.
Man looking for a shorter route home
Police tweeted: "A male was looking for a shorter route to cycle home from work. Phone app sent him on motorway so thought it OK."
Another police tweet read: "Nice chap but unaware of the rules of the road, believed it OK to ride/walk on hard shoulder - struggled to see why not.
"Genuine mistake I'm sure but could have stopped at bottom of slip road! Most children know not to stray onto a motorway."
A number of motorists also took to Twitter to vent their frustration.
One driver, Hannah Leonard, tweeted: "My usual 40 minute commute to work took an hour and a half due to a cyclist on the M25!"
Cyclists following satellite navigation system
Sergeant Phil Dix, from Surrey Police roads policing unit, said: "The cyclist was apparently taking a short cut home and was following a satellite navigation system on his mobile phone.
"It is extremely fortunate that there was a safe outcome and that the cyclist was not injured, or worse - especially as he had crossed several slip roads coming off the motorway.
"This is a good example of why motorists should always remain alert and vigilant on the roads as you never know what you may come across on your travels.
"I would urge all road users to use a commonsense approach when using a satnav, whether that be on foot, two wheels or more."
Dez Leach, Highways Agency operations manager, said: "Thankfully this was a rare event.
"Safety is our top priority and as soon as we were alerted to the incident this morning, we assisted the police to monitor the cyclist and slow traffic when necessary."
