Almost three-quarters (72%) of drivers say they want councils to crackdown on engine idling, with 44% of those saying they should be fined if they refuse to switch them off, new RAC research suggests.

However, one in four (26%) of the 2,130 drivers surveyed by the RAC say motorists should just be told to switch off without being fined, whereas 2% said offenders should be fined without any warning whatsoever.

While councils already have the power to take action against drivers who idle their vehicles while parked in the form a £20 fine, only a few choose to enforce this.

RAC head of roads policy Nicholas Lyes said: “Many of the drivers we questioned would like to see some firm action taken against offenders. This is no doubt needed to bring about a change in behaviour.”

The research found that 88% of respondents said they see drivers parked at the side of a road or street with their engines still running. This consisted of 40% who regularly witness this and 48% who see it occasionally. Only 7% claim not to have seen drivers doing this; 5% weren’t sure.

Most vehicles were generally seen parked on the side of the road in towns and cities (30%), but one in four (26%) said they have spotted drivers doing this outside schools.

Drivers’ awareness to the issue appears to be growing, with more than half of those surveyed (55%) saying they are more concerned about the impact that vehicle emissions have on the environment and public health than they were three years ago.

Lyes said: “It is clear from our research that the vast majority of drivers are far more aware of the impact of vehicle emissions than they were three years ago.

“They are conscious of pollution from parked vehicles running their engines needlessly to the point they want to see local councils taking some form of action against those who do this.

“At the very least they would like a council official to speak to those who do it and ask them to switch off.”

Asked if they would turn off their engines to prevent pollution if they were stationary for a few minutes in various locations, nearly two-thirds (64%) claimed they would outside schools; 62% would do so if parked at the side of an urban road or street; 53% outside a shop; and 53% in an urban car park.

When stopped in traffic however, attitudes are very different with 29% stating they would never turn off their engines no matter how long they were stuck for.

For those who say they would switch their engines off when stationary in traffic, the most favoured point to do so is at five minutes (18%). Thirteen per cent would do so after just two minutes and one in 10 (11%) after three minutes, and for 15% it would be after six minutes.

There was also a notable difference in attitudes towards turning off engines when stuck in traffic in urban and rural environments: 48% say they would switch off in a town or a city whereas only 39% would do so in the countryside. Worryingly, this means 23% would not turn off in any location.

The top reason for switching off when stationary in traffic was cost rather the environment or people’s health, with 37% saying they do it to save a little on fuel and 35% saying they do it when they can to help with air quality. Three in 10 (29%) however, claim it never occurs to them to turn off.

Lyes continued: “You could liken the current situation with engine idling to that of taking your own carrier bags to the supermarket: everyone knew it was the right thing to do, but few of us did it until a compulsory charge was introduced. While the law is already in place for idling, enforcement is limited, if not non-existent.

“The presence of enforcement officers and ‘no engine idling’ signs, complete with penalties, must be the next step in making our urban environments better for everyone who lives, drives and works in them.”

At the end of June this year, the Government announced that it intends to launch a public consultation looking at increasing fines for idling drivers.

A number of Councils have called for stronger powers to tackle the issue, inlcuding Westminster City Council leader Nickie Aiken who said: “Fines are our last resort but when we establish a pattern of persistent idling we need to be able to send a message.”

Aiken added fines for company vehicles, such as supermarket delivery vans, that were caught idling needed to be “a four-figure sum to be a sufficient deterrent”.
