Drivers who vape could get slapped with a £5,000 fine if vaping behind the wheel causes an accident.
There are an estimated 4.3million Brits who use a vape, according to figures from ATS Euromaster.
Those who get behind the wheel and decide to vape at the same time could run the risk of getting caught out with a fine and points if it's deemed distracting.
The act of vaping or smoking in a car is not banned. Smoking in a car is only prohibited if with a closed roof with anyone under 18 is prohibited.
However, drivers could be given a £100 fine if police conclude they failed to properly control their vehicle because they were smoking or vaping.
Motorists can be prosecuted for driving without care or attention if a plume of smoke hampers their vision and results in an accident.
In more serious cases, or those contested in court, drivers can be given a maximum £5,000 fine or up to nine penalty points and even a court-imposed driving ban.
It comes as Keir Starmer pledged to look at plans announced in Australia to restrict the sale of vapes to pharmacies and introduce minimum quality standards.
The Labour leader urged ministers to ban colourful packaging and attractive flavours for kids such as unicorn crush or cotton candy.
He told BBC Radio 5 this week: “Marketing that is pretty obviously aimed at young people should be abolished.
“We shouldn't allow that to happen because it encourages under-18s to start vaping when we don't want them to vape.”
Mr Starmer was pressed on whether the UK should follow Australia and "ban single-use disposable vapes, halt the imports of non-prescription versions and restrict the amount of nicotine in E-cigarettes".
He responded: “I haven't seen the detail of that but now you've raised it I will have a look at it because I do think there's more that we need to do.”
NHS figures for 2021 showed that 9% of 11 to 15-year-old children used e-cigarettes, up from 6% in 2018.
The Government is currently undertaking a review into how to stop children and non-smokers from starting to vape.
