What is a 'Low Emissions Zone'?

Question

I have just completed a journey in the UK. On the M40, in one place, the hard shoulder only is such a zone. Elsewhere, it seemed to apply to a different lane. Have they installed some Marcel Marceau-esque kind of invisible 'wall' that stops emissions seeping from one lane into another? ...And why?

Answer 1

An area of the country with very few Rangers fans!

Answer 2

it's bollox

Answer 3

Its a lane for people with eco cars so there's less traffic congestion and they're rewarded by being able to get to where they want to faster whilst saving the planet!

Or not, as the case may be - im personally not a believer that we're the cause of global warming. theres an 800 year lag between temperature patterns and co2 patterns in the air.

Answer 4

Is that the Viagra prescription queue at Boots?

Answer 5

lol. The Low Emission Zone (LEZ) is enforced using fixed and mobile cameras which will read your vehicle's registration number plate as you drive within the zone.

If your car does not meet the emissions standard you'll have to pay a fee.

I've just re-read your question and i didn't realise it was certain lanes. Where i drive (A2) it's the whole motorway.
