Residents have been complaining about subsidence and the crumbling road surface for two years but the council has carried out no repairs.
Now motorists hope the images - which are different sizes and point in different directions - will spur authorities into action.
Polly Birkbeck, 49, spotted the obscene graffiti, in Fetcham, Surrey, while taking her daughter to school yesterday.
She said: "I drive down there every day on the school run and said to my daughter, 'hang on a minute, someone's drawn willies on the road'.
"There are about 15 of them, I stopped the car and counted.
"They're on all the bad bits of the road, it's a sort of protest by someone with a smutty sense of humour.
"That stretch of road is really annoying, it's terribly uneven, I guess the council will just scrub them off but I'm surprised they haven't fixed this bit of road because it's been like that for years.
"It's possibly a way to highlight the issue and galvanise someone into action.
"It did make me smile - it's quite surprising to see because you don't get much graffiti around here.
"I have absolutely no idea who did it, but it must have taken a while." Cllr Raj Haque said Surrey County Council had promised fix the road this month but it has now been put back to next year.
He said the delay was "a shock to many residents who were given reassurances that the work would be under way in September".
Ian Routledge, who lives on a road joining Cock Lane, said: “This has been an issue for at least two years.
"No-one from the council will have a sensible conversation with you about what needs to be done.
“We just get fobbed off all the time.”
