They were the most common transgressions committed by the territory's 19,383 provisional drivers, who make up about six per cent of motorists, ACT Policing data showed.

Police issued 7338 fines or cautions to P-plate drivers for speeding, while another 1609 were caught using their mobile phone in 2014.

Infringements for the offences added $2.2 million, or about $42,000 a week, to territory government coffers.

Almost half of P-platers caught speeding - 3166 drivers - were travelling 15 to 30 km/h above the legal limit, while 2281 were speeding 15km/h or less.

Another 100 drivers were clocked at a speed that was 45 km/h or more above the limit, attracting a $1821 fine and six demerit points.

Of the 1609 P-plate drivers caught using a mobile phone, 1115 were slapped with a $386 fine while 494 escaped with a caution.

The figures come after the 2014 ACT Crash Report showed provisional drivers in Canberra were over-represented in road crashes.

P-platers made up 15 per cent of drivers involved in crashes that caused injuries. One of the five fatal crashes in the ACT last year involved a P-plate driver.

And of the 600 ACT motorists police busted for seatbelt offences last year, 75 were P-plate drivers, while 11 were on their L-plates.

Traffic Officer-in-Charge Station Sergeant Susan Ball warned P-plate drivers needed to be extra careful on the roads as they built up their experience and skills.

"Provisional drivers also have fewer demerit points and should put a lot more value on the points they have," she said.

"They can lose points very quickly for offences like speeding, using their mobile phone or not wearing a seatbelt.

Sergeant Ball said the loss of a licence would interfere with a P-plate driver's work life, social life and finances.

"P-platers should think carefully about what that would mean to them. Having a licence is a privilege, not a right, so value your points."

NRMA board member for the ACT and south coast region Kate Lundy said the figures for mobile phone use were particularly concerning because P-platers were already four times more likely to be in a crash than fully-licensed drivers.

"That's a really disturbing statistic that young and inexperienced drivers are putting themselves at a much greater risk because they drive and text."

She said strong police enforcement coupled with young driver education programs in schools were key to helping drive down rates of offending.

"The message to young people is just be aware how speeding and texting while driving can increase your risk of being in a crash and causing injury or death."
