You've got a steep descent there. Trucks will need to drive slowly in order not to lose control. So they force trucks into the outer lane and tell them that they should not exceed 60 (in other words: engine brake).

Not sure about the function of the holes.

Engine braking doesn't work very well with trucks. Maybe you've noticed it, trucks are on the brakes all the time, while cars can use their engine brakes downhill.

Never looked at the way trucks brake, so never noticed.

But I presume that trucks also use a lower gear when they go downhill, and then still have to brake. Or will they only brake? There has to be some rationale behind signs on motorways specifically telling truck drivers to engine brake. Those signs are typically found at the start of downhills for which I, as a car driver, do not need to engine brake at all.

These holes contain speed cameras. You are right.

Engine braking works very well on trucks. They even have a dedicated engine brake (exhaust brake), and on most modern trucks this is so effective that the brake lights of the truck is also connected to the engine brake, which in turn explains why you see the brake light of the truck almost all the time.

Must be on European trucks only then. Here you know the driver is using it just by the snarling sound the engine makes.

A44 Kassel - Eisenach

Another "milestone" for the slow-progressing A44 between Kassel and Eisenach. Construction commenced today on a 4 kilometer section of A44 between Hessisch Lichtenau-Ost and Hasselbach. It features a 1.350 meter long tunnel, and is slated for completion in 2015. It is still intended to open the whole A44 between Kassel and Eisenach no later than 2016.

The A44 will shorten driving times between the Ruhr area, Kassel and all cities along A4 between Eisenach and Dresden. However, priority of this route seems to have fallen with the completion of A38, as most traffic towards northern CZ and southern PL can now use A38, instead of the then-long awaited A44.

what is the best way from München to Kaiserslautern? i'm in doubt is it better to tak A8 all way down to Karlsruhe and then A5 or A65, or is it better to cut somewhere to A6 (A81, A7 or even A9)?

Some time ago, I had a map consisting of that stretch of A44, marked as a motorway under construction with completion date 2008 or so. Driving on A4, probably in 2006, I had decided to short cut my journey, expecting some stretches of A44 being already open to the traffic. I turned off the motorway and....after tens of kilometres of curvy and uncountable number of bends' 1x2 road, I had reached the autobahn at last. I was so happy driving on it, so you can't imagine how disappointed I got when it ended up after 2 kilometres. It was the fiasco.

@ x-type: It depends on traffic. The A8 can be quite horrible to drive on. From Ulm on A7 and then via Heilbronn (A6) isn't a long detour but with much less traffic it can be the faster route.

I've read somewhere traffic on A6 Heidelberg - Nürnberg has exploded in the last few years, and they are even considering widening it to 2x3 lanes. It is the fastest route from Czech Rep. and Poland to Southwestern Europe.

yeah, that's what i thought. none of these 3 detours aren't much longer (A81 +15 km, A7 +20 km, A9 +40 km). A81 is probabgly also congested, so if i reach Stuttgart on A8, i can continue to Karlsruhe. A9 is also probably congested, so A7 seems the most reasonable (higher traffic there should be north from Würzburg, if i am not wrong). how about Ruhrgebiet if i take A8 to Karlsruhe? A5 or A65?

the worst thing is that i will be at Ring München at monday morning that cannot be good

btw, this will be my first time driving in Germany finally

A81 is an adequate Autobahn between Stuttgart and Heilbronn. It has 2x3 lanes all the way and traffic volumes are not that high that they produce long traffic jams all the time.

I'm not sure about A6 between Heilbronn and Heidelberg though, I heard that section often in traffic reports.

I very often drive between Munich and Mannheim so I know all these options very well. Usually I look up the traffic reports on internet and decide then which way to go.
If there is no traffic jam reported I prefer the A8 over A6 because I think it's a more interesting drive (landscape wise). I find the A6 between Nürnberg and Heilbronn quite boring.
Another advantage of starting on A8 is that you still have the option to branch off on A7 or A81 in case the radio reports traffic jams building further down, while if you start on A9 you're more or less stuck on using A6 all the way through.

Nice trip though

If you want to avoid the annoying A3 between Nürnberg and Würzburg (2x2 and lots of trucks), you can use A73-A70 via Bamberg to Schweinfurt. The difference is only 2 km and it's both all Autobahn.

yeah, i thought so already.

btw i prefer going to Kaiserslautern because in that case we would use Tauernautobahn through Austria (i have never been there, i always used Pyhrnautobahn) and i would really like to pass that split part of A8 near Hohenstadt, i adore such things
