Dear Department for Transport,

Is DfT aware of the use of the so called ' 20 metre rule ' by councils given enforcement powers over bus lanes?

Does the DfT condone or approve of the use of the 20 metre rule when raising PCNs?

Is there a consistent use of the 20 metre rule and have any standardised instructions been issued on how it is to be applied by all councils to ensure consistency when raising PCNs?

Why is the 20 metre rule not included in the regulations governing use of bus lanes?

Are there any standardised instructions to councils on how the 20 metre rule is to be measured when using CCTV evidence?

Does the 20 metre rule apply to vehicles that are permitted to be in a bus lane eg where there is a TMO exemption to cross a bus lane?

Is the 20 metre rule applicable when it is not possible to cross a bus lane in less than 20 metres because of the bus lane layout eg if the bus lane passes though an island?

Other countries eg Australia and New Zealand have a similar rule but the allowance is much greater (100m and 50m). Is 20 metres to short a distance to judge for motorists and enforcement staff?

Why is the 20 metre rule not more widely publicised eg in the Highway Code?

What advice has been given by the DfT to Tribunals concerning the application of the 20 metre rule when considering appeals to ensure adjudication decisions are consistent?

Is use of the 20 metre rule lawful?

Yours faithfully,

Charles Dawson
