Can You Smoke While Driving?
A clear UK guide to smoking while driving, the law on children in cars and where you can be penalised.
The short answer
Legally yes. Smoking while driving alone is not against the law in the UK.
The big exception
It is illegal with anyone under 18 in the car.
Watch out
If it distracts you, it can still bring a penalty.
Can you smoke while driving?
Yes, you can legally smoke while driving on your own. It is not a specific offence in a private car, though it becomes illegal the moment anyone under 18 is in the vehicle, plus it can still land you in trouble if it distracts your driving. The rules are stricter than many people think.
There is a clear line to understand here. Smoking alone is treated like eating or changing the radio, while smoking with a child present is a fineable offence. This page explains the law, the children in cars rule, the distraction risk and how vaping is treated.
Let us look at the law, the children rule and the distraction risk.
It is a common source of confusion, partly because the rules changed in recent years and partly because the law treats different situations very differently. Knowing where the lines fall keeps you on the right side of both the law and basic road safety.
What the law says
Smoking at the wheel is not banned in itself. The Highway Code lists smoking as a distraction to avoid under Rule 148, yet smoking in a private car is not a specific offence any more than eating or checking a map is, so on your own you are within the law.
- Not a specific offence: smoking alone in a private car is legal.
- Highway Code Rule 148: smoking is listed as a distraction to avoid.
- Work vehicles: company vehicles used by more than one person must be smoke-free.
- Hire cars: most have no smoking policies with cleaning fees.
The catch is what smoking can lead to. If lighting up, dropping a cigarette or being distracted causes your driving to drop below a careful standard, you can be charged with careless driving, which carries a fine and points, while serious cases can mean dangerous driving.
Smoking and driving at a glance

The children in cars rule
This is the one rule most people really need to know. It is illegal to smoke in a vehicle with anyone under 18 present in England and Wales, with a fixed penalty of fifty pounds for both the smoker and the driver, even if the driver is not the one smoking.
The law applies to any vehicle enclosed by a roof, even with the windows or sunroof open or the air conditioning on. It does not apply to a convertible with the roof fully down, plus it does not apply to a 17 year old driving alone. The aim is to protect children from second-hand smoke, which is concentrated and harmful in the small space of a car.
Police have generally taken an educational approach to enforcing this, though the offence is real and the fine applies to the driver as well as the smoker. If you regularly carry younger passengers, the simplest answer is to keep the car entirely smoke free, which also spares them the lingering residue smoke leaves behind.

What about vaping while driving?
Vaping sits in a slightly different legal place. Vaping while driving is not specifically illegal and is not covered by the children in cars law, though a thick cloud of vapour that blocks your view could bring a driving without due care charge, so the same distraction rules effectively apply.
Health experts still advise against vaping with children in the car because of second-hand vapour, even though it is not banned, since it sets an example to younger passengers. The sensible approach with both smoking and vaping is to keep your view clear, stay in proper control of the car and avoid anything that takes your focus off the road. Pulling over for a break is always the safest option.
It is worth remembering that the penalty for careless driving applies whatever the cause, whether that is smoking, vaping, eating or fiddling with the radio. The common thread is staying in full control. If something is pulling your attention or your view away from the road, it is better to wait until you have stopped.
- Not specifically illegal: vaping while driving is not banned by name.
- Vision matters: a cloud that blocks your view can bring a penalty.
- Children: not illegal, though experts advise against it for their sake.
- Stay in control: keep your view clear and your focus on the road.
What does this mean in practice?
If you drive alone and smoking does not affect your control of the car, you are within the law. The moment a passenger under 18 is on board, you must not smoke, plus neither can anyone else in the vehicle. Keeping the car smoke free whenever you carry younger passengers is the simplest way to stay clear of the rules.

For the full set of guides, the quit smoking hub brings everything together in one place.
The bottom line: you can legally smoke while driving alone in a private car, since it is not a specific offence, though the Highway Code lists it as a distraction and careless driving charges can follow if it affects your control. It is illegal to smoke with anyone under 18 in the car, with fifty pound fines for the smoker and the driver. Vaping is not banned but the same distraction rules apply.
Thinking of switching?
Switching from smoking to vaping is far less harmful and helps you quit. Our vape starter kits make it simple to get started. You can also speak to the Vape Chaos team, plus a stop smoking service.
