What Did Police Find in 5 Years of Young-Driver Crashes?

Quick answer: More than 23,000 people were killed or seriously injured in crashes involving a young car driver aged 17 to 24 in Great Britain between 2021 and 2025, according to new analysis by the National Police Chiefs' Council of Department for Transport data. Around 7,500 of those casualties were the young drivers themselves, over 4,000 were passengers in cars driven by young drivers, and more than 11,600, about half, were other road users. The findings were published in September 2026, weeks before Northern Ireland introduced graduated driver licensing on 1 October 2026, the first system of its kind in the United Kingdom.

What the five-year analysis found

The National Police Chiefs' Council analysis covers killed or seriously injured casualties, known as KSI casualties, in collisions involving a car driver aged 17 to 24 in Great Britain, meaning England, Scotland and Wales, from 2021 to 2025. It was carried out by road safety data specialists Agilysis using Department for Transport data, and released on 22 September 2026 as part of Operation Spotlight on Young Drivers, which ran from 14 September to 4 October 2026.

The patterns in the most serious young-driver collisions were clear:

• Saturday recorded the highest average number of young drivers involved in collisions resulting in death or serious injury
• Weekends, evenings and night-time driving presented particular risks
• Almost a third of young drivers involved in collisions resulting in death or serious injury were involved in single-vehicle crashes, compared with 23% of car drivers overall
• Two-thirds of the young car drivers involved in KSI collisions were male
• Twice as many young drivers were involved in fatal collisions on rural roads as on urban roads, while young people living in rural areas were involved in collisions at twice the rate per head of population: 87 per 100,000 compared with 43 per 100,000 for their urban counterparts

Who pays the price

The 23,000 total matters because most of the harm falls on people other than the young driver. More than 11,600 of the casualties, around half, were other road users, including occupants of other vehicles and pedestrians. Over 4,000 were passengers in cars driven by young drivers. The Department for Transport factsheet adds detail for 2021 to 2025: passengers aged 16 to 24 made up 85% of passenger fatalities and 81% of passenger KSI casualties in cars driven by younger drivers. The passengers most at risk in young-driver cars are young people themselves, travelling with drivers their own age.

The time pattern sharpens the point. The factsheet, using grouped data for 2021 to 2025, found that younger drivers accounted for a peak of 38% of car driver KSI casualties at 2am, and that single-car collisions made up 36% of younger car driver KSI casualties.

In 2025 alone, 269 people were killed in collisions involving at least one younger car driver in Great Britain, and 4,466 people were seriously injured in those collisions.

What changed in Northern Ireland

Northern Ireland moved first. Graduated driver licensing, known as GDL, was introduced on 1 October 2026, and the Department for Infrastructure describes it as the most significant reform to driver licensing and testing in Northern Ireland in almost 70 years. It applies in Northern Ireland only. Great Britain has no equivalent system.

The Northern Ireland figures behind the change use a different age band from the Great Britain analysis. In Northern Ireland in 2024, there were 164 casualties killed or seriously injured from collisions where a car driver aged 17 to 23 was responsible. That age group accounted for 24% of fatal or serious collisions despite holding just 8% of licences.

Under GDL in Northern Ireland:

• Learner car drivers cannot sit their practical test until at least six months after their provisional licence becomes valid, and must complete a Programme of Training recorded in a logbook
• The post-test protection period rises from 12 months to 24 months, with R plates displayed for two years after passing
• For the first six months after passing, new drivers under 24 may carry no more than one passenger aged 14 to 20 between 11pm and 6am, with exemptions for immediate family members and where an accompanying person aged 21 or over who has held a full licence for at least three years sits in the front seat
• The old 45mph speed restriction for learner and newly qualified drivers is removed
• A new practical driving test follows on 1 April 2027

Breaching the new conditions can attract a fine of up to £1,000 alongside three penalty points. During the two-year probationary period, a new driver who accumulates six or more penalty points has the licence revoked and must re-test. The Department for Infrastructure cites Transport Research Laboratory findings that graduated licensing schemes reduce collisions involving young drivers by between 5% and 40%.

What it means for Saturday night, and for Great Britain

The timing of the police analysis was deliberate. Operation Spotlight ran as young people returned to school, college, university and work after the summer, while evenings drew in. Saturday recorded the highest average number of young drivers in the most serious collisions, and the risk peaks in the evening and at night.

For parents and young drivers in Great Britain, where no graduated licensing system applies, the police analysis points to practical steps that mirror the Northern Ireland rules without any legal force: building experience gradually, agreeing boundaries around passengers and late-night driving, and arranging a safe way home. The central message is that influence does not end when the test is passed, because the first months of independent driving are when experience and judgement are still developing.

How these numbers were counted

The five-year figures come from the National Police Chiefs' Council release of 22 September 2026, reporting analysis by Agilysis of Department for Transport road casualty data for Great Britain from 2021 to 2025. The Council states the total as more than 23,000. This article preserves that wording and does not treat the rounded total as an exact count. Supporting figures come from the Department for Transport's younger and older car drivers factsheet, 2025, accredited official statistics built on police STATS19 reports, where younger drivers are aged 17 to 24. Northern Ireland figures and rules come from the Department for Infrastructure's graduated driver licensing FAQs and nidirect guidance, using the age band 17 to 23. Figures can be revised in later releases.
