Motorists could be penalised and hit with a hefty four-figure fine for simply using a vape behind the wheel, according to experts. Although there is no specific rule banning motorists from puffing on their vape while driving, large plumes of smoke in the cockpit would be considered a major safety hazard. 

According to specialists, blowing out smoke could obstruct drivers' view of the road ahead and could lead to charges of careless driving. Motorists could also be penalised for driving without due care and attention, which could see individuals hit with thousands of pounds in fines if the case is taken to court. The little-known rule could see drivers caught out while heading to work, or travelling away for their summer holidays. 

Experts at Arnold Clark explained: "Drivers could be slapped with a £100 fine for careless driving if the police conclude that the driver failed to properly control their vehicle because they were smoking.

"Motorists who are distracted by cigarette or vape smoke can be prosecuted for driving without due care and attention. The plume of smoke can hamper a driver's vision and result in an accident.

"In more serious cases, or those contested in court, the charge can attract a maximum £5,000 fine, up to nine penalty points and even a court-imposed driving ban."

Previous research by IAMRoadSmart revealed that 57% of drivers admit to vaping or smoking behind the wheel. The poll found that nearly one in four road users admit to doing so regularly in a major revelation. 

The survey found that around 16% of drivers vape during long journeys, with 10% only using their device when driving alone. However, obstructed visibility could be a breach of the Road Traffic Act 1988 and lead to serious consequences.

As well as the fines, drivers could be at risk of being handed between three and nine penalty points on their licence, which could push some individuals off the roads. 

Confused.com added: "But what does the law say? Currently vaping while driving isn’t specifically illegal. However, large clouds of vapour could obscure your vision, which might result in a fine for driving without due care and attention. 

"Police have highlighted this as being dangerous, and drivers could face costly penalties and points on their licence."
