As of this morning, new laws banning smoking in cars with children inside have come into force.

The new rules mean it is illegal for anyone - of any age - to smoke in an enclosed private vehicle that is carrying someone aged under 18.

Drivers must also stop anyone who is smoking from doing so. The rules do not apply to vaping or e-cigarettes.

However, the rules only apply if there is more than one person in the vehicle. So, if a 17-year-old driver is smoking in their car alone, there is no offence.

Fixed penalty fines for each offence have been set at £50. The legislation covers any vehicle that is enclosed partly or totally by a roof. A convertible with the top down is not deemed 'enclosed'.

It is also now illegal for shops to sell e-cigarettes or liquids for them to under-18s, and for adults to buy tobacco products or e-cigarettes for under-18s.

Public health minister Jane Ellison, who is Battersea's MP, said: "Three million children are exposed to secondhand smoke in cars, putting their health at risk."
