Residents in north London believe they have found one of the shortest yellow lines in the country in their street.
The 18-inch line is one of the smallest in the country
The 18-inch parking restriction in Highbury Crescent in Highbury is just about long enough to fit one wheel.
"I was amazed to see the yellow line," said Elly Lishman, 36, who lives nearby. "It must be the smallest yellow line in the UK."
Islington Council said no ticket has ever been issued on the line, which was put there "to help drivers".
Ms Lishman said: "It wouldn't surprise me if someone got a parking ticket if they strayed on to the line."
Councillor Lucy Watt, of Islington Council, said the stretch of kerb was shared by residents' bays and pay and display bays.
"The yellow line simply separates the two," she said.
"We've actually put it there to help drivers avoid parking in the wrong one and getting a ticket.
"In Islington we take a common sense approach to parking enforcement.
"This means making sure signs and lines clearly identify the different parking bays we provide for residents and visitors."
