Tougher driving theory exams stumped nearly half of learner drivers at Scarborough test centre, figures show.
Pass rates are at a decade-long low nationwide after changes to exam questions last year, with fewer than half of would-be motorists getting the green light.
The AA called some of the questions “obscure” and said those sitting the test would need to study hard.
Scarborough test centre conducted 3,033 theory tests between April 2018 and March this year, the most recent months where data was available; with 47% of learners passing.
Driver and Vehicle Standards Agency statistics reveal 47% of learner drivers across Great Britain overcame the exam in the last 12 months, down a quarter in a decade.
The theory test, a standalone part of the driving test since 1997, has undergone reforms in recent years to make it harder.
They include upping the number of multiple-choice questions and stopping their publication in advance online, to prevent exam-takers from memorising answers.
Meanwhile, the hazard perception test, a video requiring learners to flag up dangers on the road, now simulates severe driving conditions such as snow and rain.
Across Great Britain, more than 1.3 million theory tests were conducted over the 12-month period.
Women performed strongest – 49% went on to pass compared to 46% of men.
At Scarborough test centre, 51% of female applicants came through, as well as 44% of their male counterparts.
AA president Edmund King said: “There are lots of misconceptions about learning to drive.
“One of the most enduring is that you can pass the theory test with a bit of common sense and good luck. You can’t.”
He added: “Some of the questions are a little obscure and do not seem to reflect the reality of driving and perhaps need revisiting to ensure they are relevant to drivers.”
Mark Winn, chief driving examiner for the DVSA, said: “It’s essential that all drivers demonstrate they have the right skills, knowledge and attitude to drive safely”.
