Dangerous driving - what it is and how to report it

Dangerous driving - what it is and how to report it
Dangerous driving offences include the most serious motoring charges on UK roads. If you spot someone driving dangerously, then you can help improve road safety by reporting it to the police. 

Here we help you understand what dangerous driving involves, its punishments and how you can report other motorists for endangering others.

What is dangerous driving?

Dangerous driving is committed when a motorist’s driving falls far below the standard expected of a competent and careful driver and it would be obvious to a competent and careful driver that driving in that way would be dangerous1.

How to report dangerous driving

You can report dangerous or bad driving by calling the police or submitting your witness report online after the event.

If you think the driver is a danger to themselves and other road users then you should dial 999 and report the matter to the police straight away. Ensure you are not driving and parked in a safe place when you make the call. 

You can also contact the police on their non-emergency number 101 or submit your report online. You will need the number plate of the alleged offending vehicle, an independent witness or video footage of the alleged offence, and be willing to attend court to provide evidence if required.

More than 33,000 dangerous driving videos were sent to the police in 2023, with dash cams making it easy to report dangerous drivers. Once the police has received your report of dangerous driving, the matter will be investigated by the force's Road Policing unit. 

Dangerous driving examples

A range of situations are covered by dangerous driving, from the seemingly obvious, like speeding – to lighting a cigarette in your car

Other examples include driving under the influence of drink and drugs, just as one driver did in March while reporting another motorist for drink-driving. 

Ignoring road signs could also lead to a high-risk situation and a dangerous driving charge.

Examples of dangerous driving can include:

  • Speeding, racing or driving aggressively 
  • Ignoring road signs and traffic lights 
  • Drink or drug-driving, including prescription drugs
    • This is a type of dangerous driving but there are separate offences/codes for drink and drug offences which are different to the five categories listed in the table below – these offences stay on record for longer than 4 years 
  • Driving with an injury or while being unable to see clearly
  • Knowingly driving with an unsafe load or dangerous fault
  • The driver being avoidably and dangerously distracted, for example by: 
    • using a mobile phone or other equipment
    • reading, or looking at a map
    • talking to and looking at a passenger
    • lighting a cigarette, changing a CD or tape, or tuning the radio.

The penalties for dangerous driving

Dangerous driving is split into five different offences. The penalties awarded to a driver will depend on the offence they’re charged with and the severity and circumstances of an incident.

The table below shows the points drivers face for different charges, these stay on record for four years from the date of the offence2.

DD10Causing serious injury by dangerous driving3 to 11
DD40Dangerous driving3 to 11
DD60Manslaughter or culpable homicide while driving a vehicle3 to 11
DD80Causing death by dangerous driving3 to 11
DD90Furious driving3 to 9

A DD80 and DD40 endorsement come with an obligatory driving ban, the more serious charge of causing death by dangerous driving carries an obligatory 2-year ban. 

Any driver acquiring more than 12 points on their licence within 3 years will also face a ban. 

Dangerous driving charges carry an unlimited fine, while prison terms can reach 10 years for causing death by dangerous driving (DD80), maximum sentence 14 years’ custody.

ALSO: Learner driver insurance - from 2 hours to 5 months

Can you go to jail for dangerous driving?

Whether somebody ends up in jail, and the length of their sentence, depends on the severity and circumstances of an incident. 

A dangerous driving charge doesn’t necessarily carry a prison sentence as a recent case in Durham proves, however, the maximum jail term for causing death by dangerous driving (DD80) is 14 years.

What is careless driving?

Careless driving, or driving without due care and attention, is a less serious offence than dangerous driving. 

It’s defined by law as “allowing the standard of driving to fall below that of a competent and careful driver”. 

Where dangerous driving focuses on driving standards dropping ‘far below’ the standard expected, careless driving relates to any drop in standards, no matter how small.

Examples of careless driving could include:

  • Tailgating
  • Lane-hogging
  • Allowing yourself to be distracted by eating or drinking
  • Allowing yourself to be distracted by passengers
  • Missing traffic lights, road signs or signals

Driving without due care and attention can result in receiving a fixed-penalty notice – with a £100 fine and three points on your licence, although some police forces may offer a driver education course. This can be prosecuted in Magistrates Court with maximum penalties of unlimited fine and/or 9 penalty points and disqualification for the most serious cases.

Someone using a phone while driving


What is considered using a mobile phone while driving?

Driving while using a mobile phone is a controversial and dangerous issue. The RAC even runs its own campaign called Be Phone Smart - partnering with police and road safety groups to educate and offer advice about in-car mobile phone use. 

It’s important to remember that using a phone with hands-free technology or as a sat-nav also has legal implications. As a simple rule, remember that you shouldn’t be distracted by your phone at any time while driving, even when stationary. 

The Road Vehicle (Construction and Use) (Amendment) (No.2) Regulations 2022 – changed the scope of using mobile phone whilst driving. It is now illegal to use any device “capable of transmitting and receiving data, whether or not those capabilities are enabled” whilst behind a vehicle with the engine running. This includes when the car is stationary at traffic lights or in heavy traffic. Your mobile phone needs to be entirely hands-free.

The CU80 charge or ‘breach of requirements as to control of the vehicle, such as using a mobile phone’, could see a driver awarded six points and a £200 fine.

You can also get a further 3 points on your licence if you do not have full view of the road ahead or proper control of the vehicle – for example, due to the placement of the hands-free device on your windscreen.

How to report someone using a phone while driving

You can report offenders by calling the police’s non-emergency number 101. 

Alternatively, many police forces now accept online reports of using a mobile phone while driving, you may need to be willing to attend court to give evidence and the following information:

  • The driver’s number plate 
  • Video evidence to upload
  • Independent witnesses or evidence

What is drink-driving?


Drink driving limits vary across the UK. In England, Wales & Northern Ireland the limit for drivers is 80 milligrams of alcohol per 100 millilitres of blood. In Scotland, the limit is 50 milligrams of alcohol per 100 millilitres of blood. 

Converting these limits into units is often inaccurate, as body mass, metabolism and other variables affect your blood-alcohol level. Department for Transport statistics show that there were between 230 and 270 fatalities in 2017 where at least one of the drivers was over the limit, the highest number since 2009.

A DR10 charge is issued when a driver is above the legal limit and has attempted to drive. A DR20 can be given if you are deemed unfit to drive through drink, this can apply while you are not strictly above the legal limit. 

A DR20 is still an ‘attempt’ offence – defined as driving or attempting to drive while unfit through drink.

Drivers can expect punishments of up to six months imprisonment, an unlimited fine and a year-long driving ban for either. For a more detailed explanation see our ‘Drink-drive limits: Everything you need to know’ guide.

How to report a drink-driver

Always prevent drink-driving where possible. If you’re familiar with someone who may be about to drink-drive, offer them a lift as a designated driver, or convince them to use a taxi. 

Think twice before approaching a stranger about drink-driving. If someone is trying to operate a vehicle while drunk, you should call 999 with details of the car and driver. 

If you wish to report someone after the incident has taken place you can call 101 to talk to the police.

How to report careless driving

Reporting dangerous or careless driving relies on evidence. If you see a driver putting others at risk make sure you note their registration number, the make, model and colour of their car, the time and location of the incident and any other useful information.

If it’s safe for you to record the incident, this will also help, as some police forces provide portals for reporting crime that allow video uploads. If you have a passenger with you, ask them to film footage of the incident using a mobile phone – never attempt to use a phone while driving yourself. 

You can also contact the police on their non-emergency number 101.

Things to remember when reporting careless driving


Doing our bit to make the roads safer can seem like a daunting task. However, there are a few things to remember. 

Firstly, you have the right to remain anonymous when sharing information.

Secondly, capturing evidence can be a difficult and an illegal act. A dash-cam could help you record these incidents without compromising your attention on the road. Visit the RAC Shop to find a dash cam that works for you.

And lastly, although witnessing illegal behaviour on the road can make you angry, even to the point of wanting to get their attention, but don’t become part of the problem! No matter how much you want to honk or holler out of your window, please stay calm and concentrate on your own driving.

Your passenger can take details for you, or you can pull over and jot down some notes when it's safe to do so.
