If you haven't done the test on a manual your driver license will have a restriction to automatics. I was quite surprised when I rented a large delivery van in Germany and they didn't flinch after seeing my American license. It was a Diesel manual. All they asked me was whether I had driven a truck like this before, upon which I said "Well, yes, but not this small" :-) -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

I took the exam with a stick the examiner was suitably impressed (even though I missed a gear parking - but don't think he caught it) and I passed. It was a tough car to learn a stick on too. It was way underpowered with a slushy clutch. >I was quite surprised when I rented a large delivery van in Germany and >they didn't flinch after seeing my American license. It was a Diesel >manual.

This would require the computer for the automatic transmission to have a permanent and precise GPS feed, weather data feed, traffic congestion feed and so on. Oh, and in Europe it would also have to see that old Russky truck ahead that is abruptly pulling into lane 2 and that there is a wee berm of frozen snow between lane 1 and lane 2 (had a close one there once). -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

A cyclist is still alive today because I know the road and have ABS - he was right over on my side of the road on a tight blind bend. > When we moved to the US they wanted us to do a new driving test.

When I lived in Japan after a year we had to do the Japanese driving test - which is conducted on a standard cricket pitch sized test ground (which all the driving schools faithfully replicate). The test is actually quite demanding after a fashion and more so switching back to an unfamiliar badly worn manual transmission after a year of driving fancy autos. Hardest part of the theory was remembering that "green" traffic lights are "blue" if you want to pass the test. Regards, Martin Brown

A US military driver's license listed only the vehicles you were authorized to drive. Drive anything not on that list and they lock you up. Even if there was an error on the list. I found that out the hard way in the Army. I was driving the truck I took my test in when a MP stopped me fro running a stop sign that was inside a huge bush at a corner in the officer's housing area. I asked how I was supposed to know the sign was there, when it was all he could do to pull the branches back enough to see part of it. His excuse was that I had been on base long enough to know it was there. I had been there a couple weeks, and never on that end of the base. Then he arrested me after looking at my license. It took half a day to get the civilians in 'testing' to admit that they screwed up. -- Offworld checks no longer accepted! |
