Why does everyone slow to 20-30 mph around that bend and struggle to get above 40 in their little econoboxes? Usually have to downchange to 2nd/3rd and use WOT to minimise the speed difference when joining the motorway.

Annoyingly, it's a 30 limit until the start of the motorway regulations sign (quite far around the bend), which may be a reason people slow!

Slow slip roads are good as you have an excuse to put your foot down

You should see some of the slip roads on the A34 South of the M4. Talk about short!

A12 Hatfield Peverel North used to be a dreadful sliproad, it's quite a tight corner leading up to it and it was a really short sliproad. Many a time I've seen people sitting stationary at the side of the A12 trying to join. The trick was always to get as fast round the approaching corner and then boot it so you could join a gap. I once had my Dad's Volvo 240 sideways in the rain as a result. The slip road has been lengthened now.

I was thinking exactly that. From the A303 to the A34 is short, from the A272 to the A34 is almost dangerous. In a 7.5 tonner I just have to hope someone will move for me.

No need to go that slow as the limit of vision point is good and the length of the slip allows for decent braking if needing to

From the streetview it looks like a 50 mph limit point but hard to tell unless aactually there
Good cross views of approaching traffic on motorway as you round the bend

Lots of drivers do not realise that it is quicker to slow than to speed up where merging is concerned

As I said, it's difficult as it's a 30 limit until the motorway regs actually start (quite late on)

If you want to see short slip-roads, you need to use the M50.

Hmmm... This would be my vote for dodgy slip road:

http://maps.google.co.uk/maps?f=q&source=s_q&a...

50 yards of sweeping bend, give way sign and you're in the outside lane of the motorway. Plus, because of the bend in the motorway, it's tricky to see if there's anything coming in the outside lane.

The motorway regulations start from just after the T-junction so there is room for people to get a move on before joining the motorway. Get higher up the M6 and you get the original junctions with sliproads going round tight bends and then depositing you under HGVs. This one just outside Galgate near Lancaster is one I don't really like.

Northbound on the M6 at J15 is interesting especially with the "slow" markings on the slip road!

None of this is helped by panic drivers who insist on trying to join the carriageway as soon as they are past the chevrons, regardless of their speed or the HGV immediately alongside them.

Its so uncool as well as dangerous. Why not use the sliproad and join on a bit of tarmac where there ISN'T another vehicle?

There doesn't seem to be a particular car/driver stereotype in this either (apart from 'tards).

M60 clockwise from Bredbury is a good one. Deposits traffic straight into lane 3! Theres lots of road for the joiners to get up to speed though, if only they could be bothered.

This sliproad here, on the northbound carriageway, wins my vote as probably the worst around:

http://maps.google.co.uk/maps?f=q&source=s_q&a...

The sliproad itself is elevated and travels down to meet the central motorway, which itself is rising upwards. So this effect, coupled with barriers on the side of the sliproad, make getting a good view of traffic whilst joining difficult. If there is a car in your blindspot as you go to join, you probably won't see it!

The traffic on the central motorway there is limited to 50mph but most people are doing 60mph on the main carriageway area. Sometimes it's safest to stop on the junction of the sliproad before moving out, I've seen accidents caused by people forcing their way out and the car in lane 1 on the road is forced into lane 2 where it collides with a car in it's blind spot. Similarly, I've seen cars come out with another car in their blindspot and a collision inevitably ensues. When I had my Mazda MX5 it was easier just to go another way home, as there was no real way of checking your blindspot properly in such a short space of time as it takes to join the central motorway.

Interestingly, a friend of mine was speaking to a colleague when investigating a crash that had occured on the road and the council told him that if the central motorway into Newcastle was designed these days it would look nothing like the current set up, which wouldn't be allowed as it would fail standards for visibility and lengths of on ramps and off ramps!

As you can see in the photograph, there is a car looking to join the dual carriageway with another car right next to it which is probably hadn't seen!

Still reckon the one I mentioned on the A167(M) is worse... there's no excuse for a give way sign straight into the outside lane of a motorway.

At least the bredbury junction doesn't merge into the running lanes but forms it's own lane.
