Motorists saw the vehicle "tootling along" the A601 in Derby on 2 March, with one capturing the scene on a dashcam.
Officers said they had traced the owner to the Chaddesden area.
The man, who had a stroke some years ago, also offered his apologies to other road users, police said.
PC Mark Atterbury from the Chaddesden Safer Neighbourhood Team said: "Unfortunately he had been given some incorrect information about where and when he could use it that caused him to be on a road that was very unsafe for a vehicle of that type.
"Thankfully with the information we received I have been able to pay him a visit and give him the correct advice that means he will now be able to use his scooter in a safer fashion.
"He wanted me to apologise to any of the other road users who had been concerned about his actions but is now pleased to have had the correct information."

Pte William Kemp, Cpl Sandy MacDonald, and L/Cpl James Wilson escaped their captors after convincing them they were from the Soviet Union.
Now film producers have used the tale as a premise for new World War Two drama In the Darkest Hour.
Scottish film company Burning Horseshoe Productions is behind the project.
However, it will not be a faithful re-telling of the story of the soldiers' escape from enemy clutches.
Stephen Don, a director with Northern Ireland-based Silver Sombrero Pictures which is also involved in the project, said it was a "brilliant premise" for a film.
He said: "The germ of the idea for this project came from my father who was a soldier in World War Two.
"He told me that two Scots soldiers got stuck in enemy territory and ditched their uniform in an effort to get back to their lines and avoid capture.
"Their only defence if captured was that one of the them was a fluent Gaelic speaker and would bamboozle the Nazis in a lingo which they couldn't understand."
He added: "I find it a brilliant premise to throw together two characters into a make or break situation."
The soldiers' escape from the Germans in June 1940 came weeks after their Argyll and Sutherland Highlanders regiments surrendered to enemy forces.
Pte Kemp's memoir charts their remarkable journey from Abbeville, in occupied northern France, to the safety of the British consulate in Spain.
In it, the soldier from Ballachulish, recounts the moment a German commander pointed a revolver at each of their heads after they were taken to prisoner of war camp.
When they were asked to state their nationality, Pte Kemp replied in Gaelic: "I do not know". When he was asked which country he was from, he said: "Ardnamurchan".
The men were then questioned in seven other languages - and to each they replied in Gaelic, to the confusion of their captors.
The memoir continued: "Next an atlas was produced. The interpreter took us over the various countries on the continent, one by one, and when he came to the Ukraine, I quickly pointed my finger to it."
He said the commander consulted three other officers, before saying "Allez" and opening the gate for the trio. "We were free once more", Pte Kemp wrote.
The soldiers were hailed heroes on their return to Scotland but once the Nazis got wind of the story, they targeted Gaelic prisoners for harsher treatment.
Their tale has been adapted for In the Darkest Hour, which features fictional soldiers Hamish McNeill, who speaks Gaelic, and his sergeant, Gordon McGregor.
It will look at the pair's fraught relationship as they move from the front line in France to a Nazi interrogation room in Berlin.
The film, which is still in development, is a "high concept World War Two action drama", said Mr Don.
It has received lottery development funding from Northern Ireland Screen.

Four police officers were injured in the incident on Friday night.

They are due to appear before Belfast Magistrates' Court on Monday.
The 19-year-old man has also been charged with driving while disqualified and using a motor vehicle without insurance.
An 83-year-old man spotted driving his mobility scooter on a busy city ring road has been "offered advice" by police.
