It's not unusual, particularly in urban areas, for roads to have a
separate lane to the left of the carriageway for cycles and/or buses.
Such lanes are delineated with white lines. These lines have a
non-zero width.

The question is, are the lines considered part of the lane that they
delineate? Or, to put it another way, is the width of the
bus/cycle/whatever lane measured to the inside of the white line or
the outside of the line (or, possibly, to the centre of the white
line)?

Mark,

why are you asking?

Common sense would suggest that the traffic on both sides should avoid
the line, thus ensuring there is a gap between them.

maybe you can answer my question ?? Whenever there is a cycle lane to
the left and i reach a set of traffic lights there is a *large*
section marked out, the full width of the road and about the depth of
a car and it has a pretty picture of a bicycle in the middle.

When the lights are on red some people stay out of the marked section
but other go right up to the "old" white line.

What exactly is the rule on these boxes ?

You are supposed to stay outside of then when waiting at the lights

Mark,

why are you asking?


One question is when you commit an offence. For example it's an offence
to drive a motor vehicle in a bus lane or cycle lane delimited by solid
white lines during its hours of operation.

Is an offence committed when the wheel touches the line, or when it
touches the area contained by the line? (Or perhaps when any part of the
vehicle breaks some vertical plane above such - for example wing mirrors
can protrude significantly.)

Another question is how do you know what the width of a lane is? This is
relevant in, for example, determining whether government guidelines on
the width of cycle lanes have been implemented in a particular case.

Mark,

why are you asking?

He wants to measure how wide the lane is (and compare the results with
various published standards), but doesn't know whether the white line is
*part* of the lane, or not. It'll make a difference of several inches to
the measurement.

When you arrive at the box, and the lights are already red, you must
stop at the first line. If you have crossed the first line, but not the
second, and the lights go red, you must wait at the second line (i.e.
inside the box).

If there is a cycle lane into the box, then cyclists may use this to
enter the box whilst the lights are red. Cyclist must not cross the
first line to enter the box whilst the lights are red if they do not use
the cycle lane (or gap on some boxes).

The common sense view of course may of course differ from the legally
correct answer.

The stop line closest to the lights is for bicycles. The stop line further
from the lights is for motorised vehicles, which should be fairly obvious
from the marking.
