Calls have been made for additional driving examiners to be recruited in west Cornwall so more tests can be provided.
The test centre in Penzance, which has been closed since April for maintenance, has only operated for two days a week since the pandemic. Learner drivers and instructors said it meant tests were hard to come by in a rural area where being able to drive was vital.
Rosanna Allen, from The Lizard peninsula, said: "My son's only two and I would love to be able to just take him to the park… I feel a lot of guilt."
The Driver and Vehicle Standards Agency (DVSA) said it was recruiting more examiners but it did not currently have the capacity to increase testing in Penzance.
