The increasing costs of fuel and insurance for young drivers are thought to have caused a decrease in the number of learner motorists in recent years.
The amount of people aged between 17 and 22 who have chosen to take their driving tests has dropped by almost 20% since 2005.
A representative of the Driving Standards Agency (DSA) said, "The reasons for the drop in the number of tests taken by 17-25 year-olds are not clear cut.
"We know from the statistics available from the Office of National Statistics (ONS) that population projections for 17-year-olds have been in decline since 2008; it is expected that numbers will start to increase again from 2020."
Young motorists are finding that their often limited finances are not stretching as far, particularly with the rising cost of university tuition fees and student car insurance.
While a novice driver may have expected to pay around £2,500 for cover in 2005, today they are spending upwards of £4,000 on policies.
In related news, people between the ages of 11 and 17 are being given the opportunity to learn basic driving skills during Young Driver sessions at the Butlins holiday resort in Minehead, Somerset.
The lessons may seem slightly expensive at £15 for 15 minutes, but people who have learnt how to drive from an early age apparently stand an improved chance of obtaining affordable insurance for young drivers due to the greater experience they have on the road.
