A common driving mistake could be damaging cars - and putting motorists at risk of a £1,000 fine.
Drivers could be slapped with the punishment if they try and coast while driving in their cars.
'Coasting' on the road is when you're driving in neutral or with the clutch pressed down - and it is a breach of the Highway Code.

Some believe it to be a petrol-saving method, however, this is actually a myth and you are probably doing more damage than good.
Drivers who choose to 'coast' are breaking the Highway code because they don’t have full control over the car when it's in neutral.
And while it is not illegal to coast downhill, if you get into an accident and you are deemed not to be fully in control of your vehicle and therefore you will have committed an offence.
This is because it becomes harder to break and the speed of the car will naturally increase.
Failure to have proper control of a vehicle can result in a potential fine of £1,000 or even discretionary disqualification.
John Wilmot, chief executive of LeaseLoco, has also said that coasting no longer beneficial if trying to be energy efficient.
He said: "When we drive downhill in gear our engine ECU detects that the accelerator isn’t engaged and cuts fuel from going into the fuel injectors.
"We use no fuel or very little when driving downhill in gear. However, when we drive downhill in neutral our engine and wheels become disconnected.
"This forces a small amount of fuel to be sent to the engine due to the car not receiving the rotational power it needs from the wheels, instead of drawing that power directly from the wheels."
