Understanding the law on vaping in cars with children

Are you allowed to vape in a car with a child?

We know this is not allowed for tobacco-based products in most types of vehicle, but the law doesn’t apply to the use of e-cigarettes for people vaping.

Smoking laws governing cars with anyone under 18 do not apply in the following cases:

people using e-cigarettes (vaping)
any driver if they are on their own in the car
a convertible car with the roof fully open.

Is vaping in cars with kids about to be banned?

It's no longer just talk — the government has already put a concrete plan on the table. In February 2026, the Department of Health and Social Care confirmed proposals to extend smoke-free rules to cover vapes and heated tobacco products in private vehicles carrying under-18s, alongside playgrounds and school gates. The public consultation on how the ban would work closed on 8 May 2026, and the change would come under the Tobacco and Vapes Act 2026, which received Royal Assent that April.

Then Health Secretary Wes Streeting had been explicit about the goal: stopping children being exposed to second-hand vapour in the same way they're already protected from cigarette smoke. Chief Medical Officer Professor Sir Chris Whitty has backed the move too, pointing to the health risks second-hand exposure poses to children in particular.

So is it law yet? No. As it stands, vaping in a car with children is still legal in England — but expect that to change once the government responds to the consultation and brings secondary regulations into force. We'll update this page the moment that happens, so bookmark it if you drive with kids regularly.

Is it legal to vape while driving?

Unlike the use of mobile phones, there are no specific laws banning you from vaping while driving, but you could still charged with careless driving.

Exhaling huge amounts of vapour associated with vaping while driving a car could result in your vision being obscured and see you reported by police. You could then face fines of up to £2,500 along with other penalties.

How can I be fined if vaping is legal?

Vaping with -18s in a vehicle is legal – for the moment – but Sergeant Carl Knapp of the Sussex Roads Policing Unit said: “The smoke caused by vapes are a distraction and the consequences of them can be dire, all it takes is a moment to become distracted and potentially cause a crash and even worse, a fatality.

“’There are no laws prohibiting vaping – however, you need to be in full and proper control of your vehicle at all times.”

If you drive with obscured vision, you could be charged with driving without due care and attention. This could result in fines of up to £2,500.

Are there plans to ban vaping in cars with children?

There is a growing consensus among public health experts that banning vapes in cars with children is a necessary step to protect children from secondhand aerosol exposure. Secondhand aerosol exposure is known to be harmful to children, just as secondhand smoke is. It can cause a number of health problems in children, including respiratory infections, asthma, and decreased lung function. It can also increase their risk of developing nicotine addiction.

A number of countries have already banned smoking in cars with children, and some are now considering banning vaping as well. In the United States, for example, the state of California has banned vaping in cars with children under the age of 16. This law came into effect in 2021.

There are a few arguments against banning vapes in cars with children, such as the claim that it is an infringement on the rights of adults to vape. However, the potential health benefits of banning vapes in cars with children outweigh the potential drawbacks. Banning vapes in cars with children would be a simple and effective way to protect children from secondhand aerosol exposure.

Overall, the latest thinking around banning vapes in cars with children is that it is a necessary step to protect children's health.
