Using a mobile phone or similar hand-held device while driving is not only illegal in Great Britain but also profoundly dangerous. The law, as outlined in Highway Code Rule 149, is designed to prevent driver distraction, which is a major contributing factor to road accidents. Understanding these strict rules and the serious risks involved is crucial for every driver and essential for passing your Great Britain driving theory test.
In Great Britain, the law is very clear and comprehensive: you MUST NOT use a hand-held mobile phone or similar device (like a tablet) for any purpose when driving or supervising a learner driver. This means:
The core principle is to ensure drivers have full control of their vehicle and undivided attention on the road, as required by the DVSA and the Highway Code.
Using a hand-held mobile phone while driving significantly compromises your ability to drive safely by causing three critical types of distraction simultaneously:
Combining these three distractions dramatically slows your reaction time and reduces your hazard perception, making you a significant danger to yourself and other road users.
The consequences of driver distraction from mobile phone use are severe:
The law regarding mobile phone use while driving in Great Britain is very strict. Highway Code Rule 149 states:
You MUST exercise proper control of your vehicle at all times. You MUST NOT use a hand-held mobile phone, or similar device, capable of interactive communication (such as a tablet) for any purpose when driving or when supervising a learner driver.
This rule is backed by legislation, meaning failure to comply can lead to significant penalties. These typically include points on your driving licence (often 6 points) and a substantial fine (often £200). New drivers could have their licence revoked if they accumulate 6 penalty points within two years of passing their test.
While the ban is extensive, there are two very limited exceptions:
These exceptions do not permit general usage or interactive communication.
It is not illegal to use a hands-free mobile phone or sat nav in Great Britain, provided it is properly secured (e.g., in a cradle) and you are not holding it. However, the Highway Code strongly advises against using hands-free devices for communication as they still cause cognitive distraction. As a safe driver, you should recognise that even hands-free conversations can impair your concentration and should be avoided or kept brief, especially in complex traffic situations.
Learners and even experienced drivers in Great Britain often make crucial mistakes or hold misconceptions about mobile phone use while driving:
To ensure safety and comply with the law in Great Britain, the most effective approach is:
The DVSA theory test will often include questions on the illegality and dangers of mobile phone use, particularly highlighting the "hand-held" aspect and the "any purpose" rule, including when stationary or supervising a learner. Prioritising full attention to the road is the hallmark of a responsible and safe driver in Great Britain.
In Great Britain, Highway Code Rule 149 prohibits using a hand-held mobile phone for any purpose while driving or supervising a learner, regardless of whether the vehicle is moving or stationary. The distraction caused by phone use combines visual (eyes off road), manual (hands off wheel), and cognitive (mind off driving) elements, dramatically increasing stopping distances and reducing hazard awareness—research shows reaction times can be worse than driving under the influence of alcohol. While hands-free devices are legal, they still impair concentration and should be avoided. The only exemptions are calling emergency services (999/112) in genuine emergencies and making contactless payments at drive-thrus when stationary, but general communication, social media, or navigation on a hand-held device remains illegal.
A short set of high-value points that capture the most important ideas from this theory explanation.
Using a hand-held mobile phone for any purpose while driving or supervising a learner is illegal in Great Britain under Highway Code Rule 149
Mobile phone distraction combines visual, manual, and cognitive effects, making you effectively blind and slower to react for several seconds
The ban applies even when stationary in traffic, at traffic lights, or when your engine is off but you remain in control of the vehicle
Two limited exemptions exist: calling 999 or 112 in a genuine emergency, and making contactless payments at drive-thru terminals when stationary
Hands-free devices are legal but still cause cognitive distraction and should be used minimally or avoided entirely for safety
The law uses MUST NOT with no qualifying conditions—hand-held phone use is prohibited for any interactive purpose
Supervising a learner driver means you are also banned from using a hand-held phone, even as a passenger
Penalty for using a hand-held phone while driving is typically 6 penalty points and a £200 fine, with new drivers risking immediate licence revocation
The physical act of holding the device is what makes it illegal—mounting your phone in a cradle removes the hand-held element, but only if you never pick it up
Genuine emergency calls are the only communication exemption, and contactless payment only applies when your vehicle is stationary
Believing it is acceptable to use a phone while stopped at traffic lights or in slow-moving traffic—it is not
Thinking checking the time, GPS, or a map on a hand-held phone is allowed—any screen interaction counts as use
Assuming that hands-free calling is completely safe and causes no impairment—it still causes cognitive distraction
Believing you can hold a phone briefly to adjust settings even though it is mounted—picking up the device makes it hand-held use
Thinking a supervisor can use a phone because they are not technically driving—supervisors must also be fully attentive

No, Rule 149 of the Highway Code explicitly states that you MUST NOT use a hand-held mobile phone or similar device for any purpose when supervising a learner driver. You are considered to be in control of the vehicle.
Visual distraction is looking away from the road, manual distraction is taking hands off the steering wheel, and cognitive distraction is thinking about something other than driving. Mobile phone use often involves all three, compounding the danger.
