S.O..problems with tailgaters

[ARW]

A dual carriageway is normally a 70mph limit!

[Mr Pounder]

Wrong.

Some years ago a colleague and I were driving off to another site, and had noticed that cars kept passing us then slowing down.

Then we realised we both happened to be wearing blue shirts ;)

Why?

Not when it's "signed at 40 mph".

Further more if it's illuminated and doesn't have small repeater boards giving the actual limit then the default for illuminated roads applies, ie 30 mph.

No. It might be a reason to pull out behind them, andm if they are travelling a speed lower than the speed limit, t

[charles]

round here we have quite anumber with a 50mph limit.

[Dave Liquorice]

Naw that's for the twonks that join a carriway from a slip road by simply putting on their "right" (to join) indicator. No looking or attempt to match speed.

[ARW]

That is a restricted road and not a dual carriageway.

[Bob Eager]

And that was the reason for "normally".

[Dave Liquorice]

Read it properly.

"Section 82(1)(a) (of the Road Traffic Regulation Act 1984 (RTRA

1984)) defines a restricted road in England and Wales as a road which is provided with "a system of street lighting furnished by means of lamps placed not more than 200 yards apart".

No exclusion for type of road, if it's lit it's "restricted". You obviously haven't noticed that all roads that are illuminated by street lighting and the speed limit is not 30 mph have repeater boards, dual carriageways, motorways, any road.

I think this has caused a few problems with enforcement in the A1 roadworks around Gateshead. That has average speed cameras, set at 40 for a couple of miles then at 30 for a few more before returning to

2. When the 30 first came in the only 30 signs were at the begining, no repeators as they don't technically need to be there. A week or so later I drove the same route and the 30 section had sprouted repeaters. I suspect many people didn't see the 30 boards and not knowing that a street lit road is 30. So got done, they'd then challange the penalty clogging up the system. Simpler and cheaper to bung up a few 30 boards...

The 40 average speed section and 50 leading into the 40 have always had the relevant repeaters. The national speed limit is also repeated once out of the 50 zone.

They are reasons why some drivers tailgate. I didn't say that they were justified. However, avoiding doing those things will reduce the incidence of tailgating.

[Bob Eager]

How does that work with (say) a well lit motorway, which has no such signs?

[dennis]

We have lots at 30 mph, 40 mph 50 mph and 60 mph.

[Nightjar]

I don't get tailgated and I set the speed limiter on my car according to the speed limits.

In which case the speed limit has been wrongly set. The DfT recommends that a speed limit should not be set lower than the free traffic speed of 85% of the vehicles using the road, because otherwise it will be ignored. If the LA want a speed limit that is less than the 85th percentile free traffic speed, they should introduce traffic calming measures to reduce the free traffic speed first.

...

Out of what total number of vehicles? Nationally, around 4% of cars, 5% of vans and 7% of motorcyclists would be doing more than 35mph in a

30mph limit.

Speeding is quite time of day dependent. On single carriageway roads, it can vary from 5% of drivers exceeding the speed limit to 23%, depending upon the time of day. On Motorways, it varies between 48% and 56%

Only managed to get to Wynyard and Washington today:-)

[Nightjar]

They are Special Roads, which work to a different set of rules.

I think Mr Pounders definition of normality, is mmmmm errr ............ abnormal?

[ARW]

No idea what you are talking about.

"Is pulling out behind them" what Catholic priests do?
